Abstract: Bread wheat (Triticum aestivum L.) is an important food crop and source of income for farmers at Degam district in central highland of Ethiopia. However, its productivity is mainly constrained by poor soil fertility and lack of site specific fertilizer (NPSB) recommendation in general and in the study area in particular. Thus, field experiment was conducted at Degam district on farmer's field in 2019 main cropping season to investigate the response of bread wheat varieties to blend...
Abstract: Linseed (Linum usitatissimum L.) is one of the oil crops cultivated in the highlands of Ethiopia. Its average yield is low largely due to several poor agronomic practices, biotic, and a biotic factor, among which non optimum sowing dates, seed rates, inorganic fertilizer, and improved varieties usages are the major ones. Consequently the field experiment was conducted in Horo Guduru district during the 2019 and 2020 with five objectives: (1) to identify the effect of sowing dates a...
Abstract: Use of inappropriate fertilizer type and rate, cultivation of unimproved low yielding varieties and low soil fertility are among the major constraints limiting the productivity of wheat in Ethiopia in general and in particular to the study area. Thus, field experiment was initiated to evaluate the effects of blended NPS fertilizer rates on yield components and yield of bread wheat varieties and to identify economically feasible rates of blended NPS fertilizer in the study area. The...
Abstract: One of the basic agronomic practices to improve the yield potential of common bean is identification of optimum plant spacing. Thus, field experiment was conducted to assess the effect of inter-row and intra-row spacing on the yield and yield components of common bean using variety Dursitu (DOR-811) at Chiro District in eastern Ethiopia. The treatment consisted of four inter- row (20, 30, 40 and 50cm) and four intra- row (5, 10, 15 and 20 cm) spacing arranged in factorial combinati...
Abstract: Common bean (Phaseolus vulgaris L.) is highly preferred by Ethiopian farmers because of its fast maturing characteristics that enable households to get cash income required to purchase food and household needs when other crops have not yet matured. However, the current national average yield of common bean is far less than the attainable yield under good management conditions for most improved varieties. This low yield of common bean in Ethiopia is attributed to several production ...
Abstract: Low soil fertility and poor crop management practices including useof inappropriate seeds rates are among the major constraints limiting the productivity offood barley in Ethiopia in general and in the study area in particular.Thus,field experiment was conducted to assess the effect of blended (NPSB) fertilizer and rates of seed on growth,yield components and yield of barely;and to estimate economically feasible of blended (NPSB) fertilizers and rates of seed for barely production ...
Abstract: A field experiment was conducted to study the responses of faba bean (Vicia faba L.) to phosphorus fertilizer rates and plant population at Haramaya University, Rare research site during 2019/2020 cropping season. Factorial combinations of four phosphorus (P2O5) levels (0, 23, 46, and 69 kg/ha) and six plant populations (133,333; 166,667; 200,000; 222,222; 250,000 and 300,000 plants ha-1 respectively were tested. The experiment was laid out in a randomized complete block design (RC...
Abstract: Potato is the second most important and co-staple crop in eastern Ethiopia. However, the average tuber yield is low as compared to the potential yield of the crop. The use of proper types and rates of fertilizer is one of the measures to increase productivity of the crop in the region. Therefore, a field experiment was conducted to evaluate the effect of combined application of blended NPS and Urea fertilizers on growth, yield components, tuber yield and tuber quality of potato at ...
Abstract: Low soil fertility and poor crop management practices are among the major constraints limiting the productivity of bread wheat in Ethiopia in general and Hulbareg District in particular. Therefore, a field experiment was conducted in Hulbareg District during the 2019 main cropping season to evaluate the effect of blended NPSB fertilizer rates on yield and yield components and to determine the economically feasible rates for bread wheat production. Factorial combination of three imp...
Abstract: The study was conducted in Gondar Zuria and Banja districts in Amhara Regional State, Ethiopia with the aim of evaluating genotype by environment interaction on production performance of Koekoek, Kuroiler, Sasso, and Sasso-RIR chicken under smallholder production system. About 120 total households were selected for the survey work based on purposive and random sampling methods. The survey was conducted using a questionnaire and focus group discussion. These survey data were analysi...
Abstract: aize is the major food crop in western Ethiopia and is produced in a number of agro ecologies. However, its productivity is constrained by erratic and low amount of rain fall and little availability of high yielding variety applications. Therefore, a field experiment was conducted during the 2019 main cropping season in Haramaya University of eastern Ethiopia on rare research field. The objectives of the study were to determine the effect of different tied ridge planting methods an...
Abstract: In cotton production of Middle Awash, information on the effect of inter- and intra- row spacing on lint yield, yield related traits and fiber quality of cotton are scarce. Therefore, the objective of this study was to assess the effect of inter- and intra- row spacing on lint yield, yield related traits and fiber quality of cotton. The study was conducted at Werer Agricultural Research Center’s experimental site in 2019 main cropping season on chromic vertisol (clay to silty cla...
Abstract: The experiment was conducted at Chiro District, Eastern Ethiopia, on Oda Bultum University experimental field during 2019-cropping season to assess the effects of planting densities and varieties in maize/soybean intercropping on yield related traits and yield of component crops and to identify the optimum plant density and compatible variety of soybean that maximizes productivity. Maize variety BH140at recommended population rate of 44,444plants/ha and three soybean varieties (Did...
Abstract: Population density is an important agronomic management practices in the production of potato (Solanum tuberosum L.). However, potato farmers in Ethiopia often use random population density, which contribute to the low yield of the crop. The experiment was conducted at Burka Woter in model farmers in Kersa District, East Hararghe Zone during main cropping (meher) rain season of 2019, with the aim to assess the effect of intra and inter row spacing on growth, yield related traits an...
Abstract: Common bean (Phaseolus vulgaris L.) is an important source of food and income in East Hararghe Zone, Ethiopia. However, the extent of its on-farm diversity and conservation by smallholder farmers is not well known and no sufficient information is available on the characteristics of the genotypes for production and breeding purpose. Likewise, maize is a highly productive, multi-purpose crop and the cheapest source of calorie among the cereals and it is well-suited for diverse croppi...
