Abstract This study was conducted in Meket District, Amhara National Regional State, in northern Ethiopia. Cross-sectional data collected from 214 randomly selected farm households via a structured interview protocol was used for the study. Double-hurdle model was to identify factors affecting the probability of adoption and intensity of use of improved bread wheat varieties and associated technologies in the study area. The first hurdle of the model suggests number of oxen owned by household, mobile phone ownership, education level of the household head and access to extension services significantly affected the probability of any improved bread wheat variety adoption. The intensity of improved bread wheat variety adoption was significantly associated with ownership of main plots, participation in on-farm demonstrations, perception towards shattering problems of local bread wheat varieties, and annual income of household. The findings of this study highlight the importance of economic(such as number of oxen) and institutional(such as access to extension) factors related to agricultural extension and communication, the participation of farmers in on-farm demonstrations, wealth creation and acknowledging farmers’ perception regarding improved bread wheat variety attributes. Development interventions should strive to target such economic, institutional, and psychological factors to promote wider adoption of improved bread wheat technologies.

Participatory variety selection trials were conducted in 2018 G.C in Laelay-maichew, Tahtay-maichew and Ahferom districts of central zone of Tigrai to evaluate the performance of improved bread wheat (Triticum aestivum. L) Variety and to assess farmers’ criteria for bread wheat variety selection. Six improved bread wheat varieties (Mekelle-1, Mekelle-2, Ogolcho, Kingbird and Hedasse) including the most popular variety ‘Kakaba’ were used for the study at eighteen farmers (six from each district). The experiment was laid out using randomized complete block design at baby trial with three replications. Analysis of variance revealed a significant difference among the tested varieties for most of the agronomic traits except for kernels per spike and harvest index in all the tested locations. In the preference ranking, farmers used their own traits of interest which were very important in their wheat varieties for selection. Hence, common criteria’s identified by the farmers to select the best varieties were; grain yield, biomass yield, earliness, disease resistance, spike length and seed size. Accordingly direct matrix ranking by farmers showed that Ogolcho was top ranked both at L/maichew and Ahferom followed by Kakaba, however Mekelle-1 was first ranked followed by Kakaba at T/maichew.  Therefore farmers of L/maichew and Ahferom were recommended to use Ogolcho and Kakaba, whereas Mekelle-1 was recommended for T/maichew.

Relevance and methods. The article presents the results of studied the drought and heat tolerance of bread wheat varieties on rainfed. The aim of the research is to study new varieties of common wheat obtained from the international scientific center ICARDA with high drought and heat resistance, in dry conditions and selection for further breeding work. The material of our research was 116 varieties of the international scientific center ICARDA of soft wheat. Research was carried out on bogar in the laboratory of selection and seed production of common wheat of the Gallyaral Scientific Experimental Station of the Research Institute of Grain and Leguminous Crops.Results. It selected 6 varieties of high drought and heat tolerance of bread wheat on rainfed.

The aim of this study was to identify factors influencing the intensity of use of improved bread wheat package adoption in the study area. Two kebeles was selected randomly among the potentially wheat producing kebeles in each selected districts and a total of 120 randomly selected households were interviewed for this study. Tobit model was used to elucidate factors affecting adoption of technology packages. Result of the econometric model indicated, male headship (sex), TLU and multiple production objective orientation were important variables which had positively and significantly influenced adoption and intensity of adoption of improved bread wheat production package. Whereas, age of the household, increased annual off-non farm income, increased areas of own farm land, being far apart from the farmer training center and residences had shown negative relationship with adoption and intensity of adoption. The overall finding of the study underlined the high importance of institutional support such as extension; credit and market to enhance adoption of improved wheat production package. Therefore, policy and development interventions should give emphasis to improvement of such institutional support system so as to achieve wider adoption, increased productivity and income to small scale farmers.

<p class="042abstractstekst">Information on phenotypic variation helps to breed better varieties. Forty-nine bread wheat genotypes were evaluated in simple lattice design at Jamma and Geregera to determine the extent of variation and association among 11 traits. Analysis of variance showed significant differences (<em>p </em>&lt; 0.01) among the genotypes for all traits, indicating the presence of adequate variability. Maximum values of genotypic coefficients of variation were recorded for spike length (8.66 %), number of productive tillers (8.4 %), number of grains per spike (6.4 %) and thousand-seed mass (6.15 %); this also shows the presence of substantial variability for these traits. Genetic parameters of the study revealed that days to heading, plant height, spike length, number of grains per spike and thousand-seed mass had moderate to high heritability and genetic advance as percent of the mean. Therefore, direct selection could be practiced to improve bread wheat for these traits. Moreover, selection of early-cycle lines which can escape the negative effects of climate change will be possible. Grain yield had strong and significant positive correlation with thousand-seed mass (r<sub>g </sub>= 0.395**), biological yield (r<sub>gv</sub>= 0.617**) and harvest index (r<sub>g </sub>= 0.731**); selection based on these traits will be most effective in future bread wheat yield improvement programs as they also exerted strong positive direct effects on grain yield.</p>

AbstractWheat is an important staple crop in arid and semi-arid areas of the Tigray region of Ethiopia. However, the yield and quality of the crop is markedly constrained by low soil fertility, inappropriate rate and timing of nitrogen application. Therefore, an experiment was conducted to elucidate the effect of different rates and timing of nitrogen fertilizer application on the yield, quality, and nitrogen use efficiency of bread wheat varieties during 2013 and 2014 main cropping seasons. The treatments consisted of four rates of nitrogen (23, 46, 69, and 92 kg N ha
