Introduction
e agricultural sector continues to play a dominant role in the development and growth of most African nations. Ethiopia is one of the most populous countries on the continent. In this regard, the agricultural sector is the mainstay of the economy and catalyst for the entire development of the country [1]. It accounts for about 34% of GDP [2] and 66.12% of employment [3].
Cereal crops are the main cultivated crop in Ethiopia. It contributes 81.39% and 87.97% in acreage and production for total crops, respectively, in the 2018/19 cropping season [4]. Tef (Eragrostis Tef ) is a major cereal crop and extensively cultivated in most of the agroecological zones of Ethiopia and Eritrea [5]. In Ethiopia, a total of 3.07 million hectares of land were covered in Tef in the 2018/19 cropping season. From this, 54.03 million quintals production was produced. At the country level, Tef contributes 24.32% for the total cultivated cereal crops and 17.22% for the total production in the 2018/19 cropping season. In the Amhara region of Ethiopia, Tef contributes 25.4% in area coverage, 32% of the total production in the 2018/19 cropping season, and 2.5 million rural households of Ethiopia were engaged in Tef cultivation [4].
Tef is a major staple crop in Ethiopia and Eritrea. It is the most important crop in terms of production value and cultivation area with excellent storage properties, highquality food, and the unique ability to thrive in extreme environmental conditions [1]. Besides being used to make the Ethiopian cultural food Injera (Injera is "pancake-like soft bread in Ethiopia"), its straw is used as a feed for livestock and binder of mud for house construction in rural and semiurban parts of Ethiopia [6]. Currently, Tef cultivation is spreading to other parts of the world (i.e., Australia, Canada, the Netherlands, South Africa, and the USA). Abroad, it is used for gluten (gluten is a protein found in wheat, barley, and other cereal crops. It is a major cause of lifelong gastrointestinal tract disease, which is called celiac disease. e only effective treatment for celiac disease is the total lifelong avoidance of gluten ingestion. Tef is one of the major gluten-free cereal crops [7]) free food, malting, and brewing [7].
Adoptions of improved technologies and production practices are important drivers of agricultural development in low-income countries like Ethiopia [8].
e Ethiopian Ministry of Agriculture has attempted to increase the production and productivity of Tef using conventional and modern breeding techniques and improved production technologies. So far, 42 improved Tef varieties and improved agronomic practices were released to the farming community [9]. e adoption of Tef production technology has paramount importance to increase Tef productivity, foster food security, and secure the well-being of smallholder farmers. Information on the farmers' adoption status and perception on released improved Tef technology have a paramount important prerequisite for launching new and modifying existing Tef technology packages. Such useful information is however meager in Ethiopia. erefore, this study was undertaken to assess farmers' status and perception of improved Tef technologies in the West Gojjam zone, Ethiopia.

Description of the Study Area.
Yilmana Densa district is located in the West Gojjam administrative zone about 42 Km far from the capital city of the Amhara region, Bahir Dar ( Figure 1). According to Yilmana Densa Agriculture and Rural Development Office (YDARDO) report, Yilmana Densa district has 30 rural kebeles and 4 town kebeles. e main farming system in the study area is mixed farming including crop production and livestock. e majority of farmers practice a traditional way of crop production system such as plowing in oxen, harvesting in sickles, threshing in livestock and human power, sowing in broadcast, and poor land management. Tef, wheat, maize, potato, barley, field pea, and finger millet are the major crops grown in the district.

Sampling Technique and Sample Size.
A multistage random sampling technique was employed to select sample households (in this study, a household is defined as all persons living in the same house and sharing their meals together) for this study. In the first stage, from the total of 19 potentials (out of 35 rural kebeles) Tef producer kebeles, three kebeles were selected using a simple random sampling technique. In the second stage, sample respondents were selected using a systematic random sampling technique from the selected kebeles. e sample size from each kebele was taken through population proportion (see Table 1). Availability of sample frames at the kebele agricultural office and homogeneous socioeconomic characteristics of the population were the main reasons for using this type of random sampling technique [10].
ere are many rules-of-thumb used to determine the representative sample size to conduct analysis. In this study, Kothari's [11] sample size determination was employed to select a representative sample size. e main reasons to use this sample determination are: first, it is the latest sample determination method, and second, it considers two groups, failure (nonadopter) and success (adopter). ere are two situations to consider p (population proportion of success).
First, if some approximation is known (from a previous study) that value can be used in the formula. Second, if no approximation is known, use 0.5.
is value will give a sample size sufficiently large to guarantee an accurate prediction, given the confidence interval and the error of the estimate. e reason is that when each is 0.5, the product is at maximum [10]. Based on the following equation, 224 Tef grower farmers were selected using population proportion for each kebele: where we have the following: (1) n � estimated sample size (2) e � the allowable error, where e � 0.05 (3) N � total Tef grower farmers (N � 2584) (4) p � the estimated proportion of an adopter that is present in the population, which is 0.8 (from a previous study by Tamir [12]) (5) q � the population proportion of nonadopter in the population. q � 1 -p, where q � 1 − 0.8; therefore, q � 0.2 (6) Zα/2 � standard variate for given confidence level (as per normal curve area). It is 1.96 for a 95% confidence interval

Source and Type of Data Collection.
In this inquiry, crosssectional data were used for achieving the objective of the study. Data were collected from primary and secondary sources. Primary data were collected from the sample farmers using a structured interview schedule from 224 Tef grower sampled farmers. Primary data such as demographic, socioeconomic, institutional, farmer's perception, and plotlevel data were collected using Kobo Toolbox (KoBo Toolbox is a free open-source tool for mobile data collection, available to all. It allows collecting data in the field using mobile devices such as mobile phones or tablets, as well as with computers) software. e data were collected using qualitative and quantitative approaches from sampled farmers. Information was gathered from the kebele administrative body, development agent, and district agricultural officers to capture supplementary information and to observe the validity of information from the household survey. Secondary data such as theories and models, empirical evidence, and supplementary data to primary data were collected from the journal article, previous studies, agricultural office manuals, proceedings, and NGO reports.

Methods of Data Analysis.
After the data was collected, the data were arranged, coded, managed, and analyzed by using STATA version 15.1. e results were interpreted and discussed using descriptive and inferential statistics. Descriptive statistics such as mean, standard deviation, percentage, and frequency distribution were used to describe the socioeconomics, institutional, and demographic characteristics of the respondents. Furthermore, inferential statistics were used to compare the means (i.e., one-way ANOVA) between adoption categories.

Status of Adoption of Tef Technology
Packages. To know the aggregate adoption level of Tef production technology, first, it was listed for the main components of the technology packages based on the Tef production manual, which was prepared by the Amhara National Regional State Bureau of Agriculture collaborated with ATA and EIAR in [13] for package study, giving equal weights for each package not acceptable because some components are easy to implement, while others are difficult to implement. In addition, all components do not have equal contributions to specific crop production.
Many scholars such as Mulugeta [14], Wuletaw and Daniel [15], Ogunya et al. [16], and Julius and Jimoh [17] had given weight to each package to obtain the intensity of adoption of a given technology. erefore, this study has given different weights for each package of Tef production technology (see equation (2). Based on the weight, the Tef grower farmer's adoption level was calculated. Accordingly, the adoption index of the technology was calculated as follows: where ATi is the level or number of packages (plowing frequency, seed type, crop rotation, fertilizer rate, seed rate, sowing method, and weeding frequency) of the i th farmer applied. RTi is the recommended level or number of packages farmers ought to apply, ISi is the proportion of score (weight) for each package. AIi is the adoption index of the i th farmer. As already explained above, researches conducted on agricultural technology adoption had been using weight to calculate adoption intensity. For instance, Mulugeta [14] used weight to calculate the intensity of the adoption of old coffee stumping technology packages. Wuletaw and Daniel [15] give a proportion score to calculate the adoption intensity of Malt-barley. Research conducted by Ogunya et al. [16] used weight for each package to calculate the adoption intensity and level of Nerica rice varieties in Ogun, Nigeria. Julius and Jimoh [17] give weight for each technology packages to calculate the intensity of adoption of cocoa production technology packages in Ekiti State, Nigeria. ey calculated the weight from sample respondents. Hence, this study computed the proportion score (weights) of Tef production technology packages from district agricultural experts and model farmers.

Farmer's Perception towards Improved Tef Technology
Packages. Farmers' perception towards improved Tef varieties and row planting was analyzed using five-point Likert scales as strongly agree (5), agree (4), undecided (3), disagree (2), and strongly disagree (1). e least favorable degree is given the least score (1), and the most favorable is given the highest score (5). e study used relative importance index (RII) analysis to rank the attributes of improved Tef varieties and row planting methods according to their advantages and disadvantages. e following formula was used to determine the relative index [18].
Ethio-Region   Advances in Agriculture where RII is the relative importance index, A is the highest weight, N is the sample size, and W is the weight as assigned by each respondent on a scale of one to five with one implying the least and five being the highest. Scales for measuring farmers' perceptions were given from one to five. One implies the least, and five is the highest.

Results and Discussion
3.1. Demographic Characteristics. As shown in Table 2, from the total sample respondents, 85.27% were male-headed, while the remaining 14.73% were female-headed. Another notable result is that the mean age of the sample household heads was found to be 44.63 years with a standard deviation of 12.05. is shows that majority of the household heads were found at productive age. e average family size of the household was 5.16 persons. e mean labor force based on the conversion factor of man-day equivalent was 2.76. is shows that over half of household members can work on the farm. In the case of the Yilmana Densa district, farmers starting their farming at the early age 18 s. Due to this, the majority of the household heads have solid Tef farming experience (24.50 years). Educated farmers are taught to adopt and peruse in using improved technology. e average education level of sample households was 1.35 with a standard deviation of 1.327. is implies farmers in the study area are not well educated.

Current Status of Farmers on the Adoption of Tef Technology Packages.
e agronomic practice of improved Tef production technology package contains land preparation, crop rotation, improved seed, sowing method, planting date, seed rate, rate of fertilizer application, the timing of fertilizer application, weeding frequency, disease prevention, pest prevention, harvesting time, threshing method, and storage system. However, all the packages were not included in this study to calculate the adoption index because it is difficult to get reliable data for some packages (i.e., sowing date and harvesting). Furthermore, some packages are included in other packages. For instance, the recommendations of disease and pest prevention are integrated under management such as plowing frequently, deep plow, applying crop rotation, and use of improved seed. erefore, those packages are included in crop rotation, improved seed, and plowing frequency. Eventually, this study included plowing frequency, crop rotation, rate of fertilizer application, seed type, seed rate, sowing method, and weeding frequency to know adoption status and intensity of Tef production technology in the study area.
e actual adoption categories were categorized into four groups such as nonadopter, low adopter, medium adopter, and high adopter based on the adoption index. e index score is 0.00, 0.01-0.33, 0.34-0.66, and 0.67-1.00, which represents none, low, medium, and high adopters, respectively. Similar studies, Endeshaw [19], Bosena and Susie [20], and Dawit and Gemechu [21], used similar techniques. Table 3, from the total sample households, 21.43%, 3.13%, 69.64%, and 5.80% were categorized under none, low, medium, and higher adopter of Tef production technology packages, respectively. e result indicates that the average adoption index was 0.43 with a standard deviation of 0.24. is implies that farmers in the study area are categorized as medium adopters. ere is a significant mean difference between adoption categories in the adoption index at less than 1% level of significance.

As shown in
According to Table 4, from the total sample households, 78.57% of farmers were using improved Tef varieties. Evidence from the key informants in Goshiye kebele indicates that farmers in the sample kebele accessed improved seed from Avolla Goshiye community-based seed enterprise since 2014. Due to the fact, in the study area, majority of farmers are used improved Tef seed. Contrary to this, only 4.91% of the sample households applied the Tef row planting method in their Tef plots. Evidence from farmers' perception towards the row planting method indicates that farmers do not apply this package due to its low straw quality for the livestock feeding, more time consumption, and high labor consumption even they are accepted better yield, reduced seed cost and convenient for weeding attributes of the package. e result is consistent with the findings of Bart et al. [1]. e recommendation of seed and fertilizer rates for Nitosols and Vertisols are different. As shown in Table 4, 79.61% and 79.01% of the farmers applied improved Tef seed in their Nitosols and Vertisols, respectively. Another notable result is that 97.55% and 98.77% of the sample households applied urea and NPS/NPSB fertilizer for Nitosoils, respectively. Similarly, 93.87% and 93.25% of the farmers who have Vertisols applied urea and NPS/NPSB, respectively. is implies that farmers applied inorganic fertilizer almost in all their Tef plots. In addition, the adoption status of weeding and plowing frequency was found that the sample households were adopters (100%), whereas only 91.07% of the sample households were applied crop rotation in their Tef plots. is implies that the majority of farmers are applied crop rotation to reduce weed and improve soil fertility. According to Table 4, there is a significant mean adoption index difference between adopter categories in all the Tef packages at a 1% level of significance. Table 5, the average area allocated in improved Tef seed was 0.31 ha with a standard deviation of 0.21, whereas the average area covered under local varieties was 0.16 ha with a standard deviation of 0.15. is implies that in the study area, the majority of sample households covered their Tef plot in improved seed rather than local seed.

Advances in Agriculture
As illustrated in Figure 2, the most cultivated improved Tef varieties in the study area were Quncho (70.98%) and Etsub (7.59%). e remaining 21.43% were covered in local Tef varieties (i.e., Davo, Dimbito, Fesho, and Qey Tef ). is implies that adopter farmers are cultivating their Tef plots based on the recommendation of improved Tef varieties.
As shown in Table 6, low, medium, and high adopter farmers cover their Tef plots on average 0.14 ha, 0.27 ha, and 0.47 ha on improved seed, respectively. is shows that low, medium, and high adopters covered 36.84%, 54.00%, and 90.38% of their Tef lands with improved seed, respectively. e result implies that high adopters relatively covered their Tef plots widely in the improved seed. ere is a significant mean difference between adopter categories with respect to adoption intensity of improved Tef variety at less than 1% level of significance.

Adoption of Seed
Rate. Recommended seed rates for Nitosols and Vertisols are 25 kg ha −1 and 30 kg ha −1 , respectively [23]. As provided in Table 7, respondents on average applied 26.83 kg ha −1 and 32.89 kg ha −1 seed rates for Nitosols and Vertisols, respectively. Another notable result is that on average, low, medium, and high adopters applied 34.16 kg ha −1 , 37.04 kg ha −1 , and 32.73 kg ha −1 seed rate on their Nitosols Tef plots, respectively. Likewise, the low, medium, and high adopters applied on average 34.11 kg ha −1 , 48.42 kg ha −1 , and 38.82 kg ha −1 on their Vertisols Tef plots, respectively. Respondents in the study area applied 26.83 kg ha −1 and 32.89 kg ha −1 for Nitosols and Vertisols, respectively. It is worthwhile to note that farmers applied seed rates above the recommended rate. ere is a significant mean difference between adopter categories with respect to seed rate in Nitosols and Vertisols at less than 1% level of significance (see Table 7).

Adoption of Fertilizer.
In the study area, farmers use both organic and inorganic fertilizers in their plots. Source: own survey data, 2020. * * * p < 0.01, * * p < 0.05, * p < 0.1, and ns P > 0.1.  Farmers applied organic fertilizer for small plot crops, which are growing around their dwellings such as potato, maize, cabbage, and permanent crops (i.e., mango, coffee, and Gesho). However, they did not apply for Tef crops because it grows apart from their residence house and are covered in a large area. On the contrary, all respondents (100%) applied inorganic fertilizer in their Tef plots (see Table 8). is implies that the majority of farmers in the study area applied inorganic fertilizer than organic fertilizer in their Tef plots. Nowadays, Tef production is unimaginable without inorganic fertilizer. As provided in Table 9, from the total respondents, 98.66% and 100% applied urea and NPS/NPSB fertilizer, respectively. On the other hand, fertilizer adopter farmers have applied 71.43 kg urea ha −1 and 104.16 kg NPS/ NPSB ha −1 on average. is implies that Tef growers applied artificial fertilizer below the recommendation rate.
is implies that Tef grower farmers applied urea fertilizer below the recommendation rate. One-way ANOVA result shows that there is a significant mean difference between adopter categories in relation to the rate of urea fertilizer in both soil types at less than 1% level of significance.
(2) NPS/NPSB Fertilizer. e recommendation rate of NPS/ NPSB fertilizer for Tef is 125 kg ha −1 and 150 kg ha −1 for Nitosols and Vertisols, respectively. Sample households applied on average 110.47 kg ha − 1 and 97.19 kg ha −1 NPS/ NPSB fertilizer for Nitosols and Vertisols, respectively (see Table 11). Low, medium, and high adopters applied 38.46 kg ha −1 , 96.55 kg ha −1 , and 124.73 kg ha −1 NPS/NPSB fertilizer for Nitosols, respectively. Similarly, medium and high adopters applied 95.57 kg ha −1 and 119.50 kg ha −1 NPS/ NPSB fertilizer for Vertisols, respectively. is implies that farmers in the study area apply NPS/NPSB below the recommendation rate. One-way analysis of variance (ANOVA) result indicates that there is a significant mean difference between adopter categories with regard to the rate of NPS/ NPSB fertilizer application at less than 1% level of significance.

Adoption of Plowing Frequency.
Plowing is one of the crucial packages in Tef production. Its frequency varies from 2 to 4 times based on soil type and weed and pest infestation conditions. A mechanized plowing method is recommended for better plowing [13]. However, in the study area, mechanized plowing (i.e., tractor) is nonexistent at the farmer's level. As depicted in Table 12, sample Source: own survey data, 2020. * * * p < 0.01, * * * p < 0.05, * * * p < 0.1, and ns P > 0.1. Source: own survey data, 2020. * * * p < 0.01, * * * p < 0.05, * * * p < 0.1, and ns P > 0.1. Advances in Agriculture 7 households plowed their Tef plots using oxen 3.71 times plot −1 with a standard deviation of 0.42. is implies that farmers in the study area plow their Tef plots relatively based on the recommended frequency. Low, medium, and high adopters plowed their Tef plots on average 2.5 times plot −1 , 2.5 times plot −1 , and 3.73 times plot −1 , respectively. ere is a significant mean difference across adopter categories in relation to plowing frequency at a 1% significant level.

Adoption of Weed Management.
e management practice of weed remains one of the most tasks for Tef growers due to its poor competitive ability with weed. e manual weeding management method is recommended for Tef grower farmers [24]. According to Table 13, from the total respondents, 66.67% were used of manual-only weed control method, whereas the remaining 33.33% of the respondents used chemical and manual methods. is implies that in the study area, the majority of households manage  Source: own survey data, 2020. * * * p < 0.01, * * p < 0.05, * p < 0.1, and ns P > 0.1. Source: own survey data, 2020. * * * p < 0.01, * * p < 0.05, * p < 0.1, and ns P > 0.1. (1) Frequency of Manual Weeding Management per Plot. e recommendation frequency of the manually weeding control method is two to three times [13]. As shown in Table 14, of the total respondents, 47.32% of households were managed their Tef plots with a frequency below two, whereas 52.68% managed two and above frequency using manual method. is implies that the majority of households practice manual weeding management based on the recommended frequency.
(2) Farmers Adoption Status of Weeding Frequency. As shown in Table 15, adopter farmers managed manually their Tef plots 1.75 times plot −1 on average with a standard deviation of 0.49. Another notable result is that low, medium, and high adopters applied 1.12 times plot −1 , 1.76 times plot −1 , and 2.29 times plot −1 with manually weed control methods on average, respectively. is implies that farmers practice manual weed management methods based on the recommended frequency. One-way analysis of variance results indicated that there is a significant mean difference across adopter categories with regard to weeding frequency at a 1% level of significance.

Adoption of Crop Rotation.
Crop rotation is another vital technology package in Tef production. e Ministry of Agriculture suggested farmers should not be planting Tef for two consecutive years on the same plot [22]. As shown in Table 16, sample households on average rotated their Tef plots 0.74 times plot −1 with a standard deviation of 0.32. Low, medium, and high adopters rotated their Tef plots 0.33 times plot −1 , 0.55 times plot −1 , and 0.97times plot −1 , respectively. On average, the respondents rotated their Tef plots 0.74 times. is implies that farmers in the study area practice monoculture production practice in consecutive cropping seasons. One-way analysis of variance results indicated that there is a significant mean difference across adopter categories with regard to crop rotation at a 1% level of significance.

Planting Method.
Row planting by hand or machine at a row distance of 20 cm or transplanting at 10 to 15 cm between plants within a row is recommended to alleviate lodging and increase production and productivity of Tef [25]. Respondents in the study area were covered only 0.01 ha in a row planting method (see Table 17) from the average 0.47 ha Tef land (see Table 6).
is implies that farmers in the study area seem to totally exclude the row planting method. is is because the row planting method is a backbreaker, labor-consuming, and lack of efficient row planter machine. e result is consistent with the findings of Joachim et al. [25]. One-way analysis of variance results indicated that there is a significant mean difference across adopter categories at a 1% level of significance.

Productivity of Tef in the Study Area.
At the national level, the expected Tef production is 2,300 kg ha −1 [26]. Table 18 shows survey respondents' of Tef production ha −1 during the 2019/20 cropping season. According to the table, the average Tef production ha −1 in the study area was 954.90 kg ha −1 . It is worthwhile notable that Tef production is very low in the district. As can be seen, adopters are exceeding 96 kg ha −1 than nonadopter. Another notable result is that there is a significant production mean difference between adopters and nonadopters.

Farmers' Perception towards Improved Tef Technology Packages.
is part of the study was including the two core technology packages such as the improved Tef varieties and row planting technology packages.

Farmers' Perception towards Improved Tef Varieties.
To obtain farmers' preference of Tef varieties, first, the list of attributes are identified, which helps farmers characterize the different varieties of Tef. is was done by consulting Tef seed multiplication cooperatives (i.e., Avolla Goshiye farmers' seed enterprise), research center (i.e., Adet research center), and kebele plant science experts and validating the information with farmers. e identified attributes were better grain yield, tolerance to disease, lodging tolerance, good germination, early maturity, and high straw quality.

Advances in Agriculture
(1) Improved versus Local Varieties. Table 19 shows the result of farmers' perception embodies in local and improved Tef varieties. As it can be seen, 89.73%, 87.05%, 59.38%, 45.54%, and 41.52% of the respondents perceived that improved seed is better in grain yield, germination, disease, early maturity, and tolerance to lodging than local Tef seed, respectively. However, 70.54% of the farmers perceived that the straw quality of local seed was better than the improved seed. is implies that attributes of improved Tef varieties are better than their counterpart local Tef varieties. According to Figure 3, the respondents who agree with improved Tef variety have high yield, high disease resistance, early maturity, straw quality, and better germination were higher in adopter groups than nonadopter groups. When comparing adopter and nonadopter respondents with improved Tef varieties that have high lodging tolerance, the former one has a positive perception than the latter. e result shows that adopter groups in the study area perceived that improved Tef varieties are better than local varieties in different attributes.
is implies that positive perceptions towards the technology has utmost importance to adopting the technology.

Farmers' Perception on Improved Tef Variety
Attributes. Farmers' perception on the use of improved Tef technology is generally attached with the advantages of technology components. Farmers examine the advantages from the view of profitability and compatibility. Davis [27] suggested that the "degree to which a person believes that using a particular technology would enhance production" is a major factor that affects the acceptance of technology. Based on this farmers' perception on improved Tef varieties, they have been included in this study. Accordingly, ratings such as strongly agree (5), agree (4), undecided (3), disagree (2), and strongly disagree (1) were used to measure the respondents' perception of the technology. e value (5) indicates that how farmers perceived technology as highly positive, and values less than (3) show how farmers perceived the technology as negative or poor. According to Source: own survey data, 2020. * * * p < 0.01, * * * p < 0.05, * * * p < 0.1, and ns P > 0.1.  Source: own survey data, 2020. * * * p < 0.01, * * * p < 0.05, * * * p < 0.1, and ns P > 0.1.       Table 20, the grand mean (3.31) shows that the overall perception of the respondents based on the given attributes was positive. e result also shows that farmers' perceptions on straw quality (2.12) and lodging tolerance (2.74) capacity were negative. Negative perception for straw quality of improved Tef varieties could be because farmers need soft and weak straw for livestock feeding, but the quality of improved seed straw is strong. is result is consistent with Regasa et al. [28] and Dawit and Gemechu [21].

Relative Importance of the Attributes of Improved Tef
Variety. As shown in Table 21, six Likert scale items were included to measure the relative importance of improved Tef varieties. Accordingly, the relative importance index was developed to determine which items were very highly important and of less importance. e result shows that high grain yield, good germination, early maturity, disease resistance, high tolerance to lodging, and better straw quality for livestock feeding ranks first to sixth, respectively. is implies that tolerance to lodging and straw qualities are less important attributes of improved Tef variety.

Farmers' Perception towards Row Planting Method.
As illustrated in Figure 4, farmers in the study area perceived that the Tef row planting method is labor-intensive, consumes more time, and has low straw quality for livestock feeding than the broadcast method. Moreover, farmers perceived these attributes as demerits of the row planting method. However, they perceived that row planting has a high grain yield, is convenient for weeding, saves fertilizer cost, reduces seed rate, and has high tolerance to lodging than the broadcast planting method. Surprisingly, farmers perceived that row planting has paramount importance to boost Tef yield by reducing competition between Tef plants for water, light, and nutrients. Eventually, Figure 3, shows the comparison between adopter and nonadopter farmers with relation to perception towards row planting method.
To measure farmers' perception towards the row planting method, 5 and 3 Likert scale statements were included (see Table 22). e result shows that reduced seed cost, reduced fertilizer cost, high grain yield, convenience for weeding, and tolerance to lodging were perceived by the farmers as a relative advantage with item mean of 4.65, 4.59, 4.56, 4.49, and 3.37, respectively. On the other hand, high labor and time consumption and low straw qualities were perceived as a relative disadvantage with item mean of 4.82, 4.73, and 4.65, respectively. e grand mean (4.33) of relative advantage shows that the overall perception of the respondents with relative advantages of the row planting method is positive. On the other hand, the grand mean (4.73) of relative disadvantage shows that the overall perception of the respondents with a relative disadvantage of row planting was highly negative.

Relative Importance Index of Row Planting Method.
As shown in Table 23, eight Likert scale items were included to measure farmers' perception towards relative importance and disadvantage of the Tef row planting method. From the advantage side of Tef row planting method, reduce seed cost, reduce fertilizer cost, high grain yield, convenient for  Advances in Agriculture 13 weeding, and tolerance to lodging are ranked from first to fifth, respectively. On the other hand, from the disadvantage side, consume high labor, time-consuming, and low straw quality are ranked from first to third, respectively.

Conclusion and Recommendations
e findings verify that farmers in the study area were found at the medium level of adoption of Tef production technology (i.e., the average adoption index is 0.43). e findings also confirm that farmers perception towards the relative advantages shows that high grain yield, good germination, early mature, and disease resistance capacity were perceived by the farmers as the most crucial attributes of improved Tef varieties, whereas straw quality and tolerance to lodging were perceived as the least important of attributes of the technology. e findings also verify that even if farmers perceived that Tef row planting method has a high yield, reduces the quantity of seed and fertilizer costs, and has convenience for weeding, but time consumption, low straw quality, and high labor consumption nature of the technology are major bottlenecks to apply Tef row planting method. e most crucial issues in the Tef row planting method are the high labor and time consumption nature of the technology. Due to this reason, farmers prefer the broadcast planting method even if they accepted high yield and convenience for field management attributes of the technology. erefore, the Ministry of Agriculture of Ethiopia, particularly the Amhara Region Bureau of Agriculture, and Yilmana Densa District Office of Agriculture should avail easy, efficient, and least time; low labor consumer; and costeffective row planter technology for the farmers. According to the finding of this inquiry, farmers perceived lodging tolerance attributes of improved Tef varieties as the least important. ey also raised this attribute as a major bottleneck for their Tef production process. erefore, the efforts and the commitments of plant breeders and genetic specialists to develop Tef varieties would help reduce lodging Tef through hybridizing semidwarf Tef varieties. e postharvest practice of Tef technology can be future research priority.
