The estimated results indicated that Geographic locational and farm size were significant in explaining both the decision to participate in purchasing wheat seed and the level of wheat seed purchase. Improved wheat variety use in the last five years has been found to have a negative relationship on farm households’ decision to purchase wheat seed but it was not important on the quantity of wheat seed purchase. With regard to educational level, out of the education levels identified, farm households who only read and write have a less likelihood to participate in purchasing of wheat seed. In addition, economic factors such as income and livestock ownership were among the significant determinants of wheat seed purchase demand. Calculated non-farm income elasticties, ...

Both purposive and two-stage sampling techniques were used. Primary data was collected from 157 randomly selected wheat producing farmers through a structured questionnaire. The translog production function analysis revealed that the mean technical efficiency of wheat producers in the study areas in the season were 55%. Given the present state of technology and input level, the result of the study suggests that there is plenty of scope to increase the output of wheat commodity by up to 45%. Education, gender, fragmentation (number of wheat plots), and access to input and output markets have negative coefficients in the inefficiency model. In addition to this, the study indicates scaling up/out of best farmers' practices in the use of recommended integrated soil, water and nutrient management practices is essential for improving the productivity of commercial wheat varieties grown under waterlogged vertisols. Furthermore, sharing the benefits of improved technologies through informal education and field days in demonstration plots could be important possible interventions for obtaining maximum achievable wheat yield under the difficult growing conditions of waterlogged vertisols in Ethiopia.

However, wheat productivity has remained low. This study was carried out in Ethiopia Aris Zone to determine the level and impact of adoption of improved wheat varieties on wheat productivity and farm income level of wheat producers in the country. The study employed the propensity score matching method to carry out the impact study. It was found out that the rate of adoption of improved wheat varieties in 2013 was 56%. Probit model showed that sex of household headship and livestock ownership enhanced adoption of improved varieties, while the educational level of the household head negatively affected in enhancing the adoption of improved wheat varieties. According to the result of the propensity score matching method, improved wheat variety adoption on average increased wheat productivity of adopters by about 1 to 1.1 t ha-1 than the non-adopters. Similarly, the result of the propensity score matching estimates showed that the average income of adopters was 35 to 50% greater than the non-adopters.The results provide empirical evidence that agricultural technology adoption can contribute to improving productivity and raising income of farm households. RÉSUMÉ Blé (Triticum aestivum L.) est l'une des cultures de céréales les plus importantes cultivées dans une large gamme de produits agro-écologiques en Afrique orientale. Cependant, la productivité du blé est restée faible. Cette étude a été réalisée en Ethiopie Aris Zone pour déterminer le niveau et l'impact de l'adoption de variétés améliorées de blé sur la productivité du blé et au niveau des producteurs de blé dans le pays du revenu agricole. L'étude a utilisé la méthode score de correspondance de propension à mener à bien l'étude d'impact. Il a été constaté que le taux d'adoption de variétés améliorées de blé en 2013 était de 56%. modèle Probit a montré que le sexe du chef de famille et la propriété de l'élevage amélioré l'adoption de variétés améliorées, tandis que le niveau d'instruction du chef de ménage affecté négativement dans l'amélioration de l'adoption de variétés améliorées de blé. Selon le résultat de la méthode score de correspondance de propension, l'amélioration du blé variété adoption sur la productivité moyenne du blé a augmenté des adoptants d'environ 1 à 1,1 t ha-1 que les non-adoptants. De même, le résultat des estimations d'appariement des scores de propension a montré que le revenu moyen des adoptants est de 35 à 50% plus grand que les résultats non-adopters.The fournir des preuves empiriques que l'adoption de la technologie agricole peut contribuer à améliorer la productivité et l'augmentation du revenu des ménages agricoles.

The estimated results indicated that Geographic locational and farm size were significant in explaining both the decision to participate in purchasing wheat seed and the level of wheat seed purchase. Improved wheat variety use in the last five years has been found to have a negative relationship on farm households' decision to purchase wheat seed but it was not important on the quantity of wheat seed purchase. With regard to educational level, out of the education levels identified, farm households who only read and write have a less likelihood to participate in purchasing of wheat seed. In addition, economic factors such as income and livestock ownership were among the significant determinants of wheat seed purchase demand. Calculated non-farm income elasticties, for those who purchased wheat seed, indicated that farmers' wheat seed demand sensitive to changes in non-farm income. Introduction Availability of quality seed of improved varieties at required amount and affordable prices has been amilestone of developments recorded in wheat production. Assured supply of breeder's and pre-basic seed is crucial for public breeders to engage private companies to produce seed of public cultivars. In a regional seed market, companies may need breeders and pre-basic seed to produce and sell seed in several countries. Failure to use appropriate seed, while investing sufficiently on other inputs and management practices, usually yields against expectations. This can be observed in the improved seed coverage and national wheat productivity in Ethiopia. During the main rainy season of 2009/2010, of 1.68 million hectare of land covered with wheat, only 2.25% was sown with seeds from the formal sources (CSA, 2010)1 1 indicating that the vast majority of seeds used by small farmers in the country is obtained from the farmers' seed system. Moreover, DawitAlemu and Spielman (2006) 2 had summarized that only 20% of the demand for improved seed was covered in the main rainy season of 2005 demonstrating that nearly 3000 tons of improved wheat seed is required to satisfy the present demand. Experience has shown that the predicted demand for wheat seed usually does not conform to the demand at planting times. When farmers revise their expectations of rainfall, prices and other factors, they incline to shift their interests. This frequently causes significant coordination problems for seed suppliers. This is well evidenced by the present national scaling up initiative by the EIAR and seed sales reports by seed suppliers. Hence, clearly defining demand dynamism for wheat seed has a crucial. To this end, this paper was carried out with the objective of presenting the important farm household Socio-demographic characteristics that are affecting wheat seed demand and investigate their effects on wheat seed demand.
