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: 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: 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: 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: 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: 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: Common bean is among the most important food and cash legume crops cultivated in southern Ethiopia. But, its productivity in the country remains far below the genetic potential to be attained. This is partly due to low soil fertility management and a lack of improved varieties. Therefore, the study was conducted to evaluate the effect of blended NPSB fertilizer rates on growth, yield components and yield of common bean varieties and to assess economic feasibility of common bean var...
Abstract: One of the basic agronomic practices to improve yield potential of chickpea is identification of optimum plant spacing. Thus, field experiment was conducted to assess the effect of inter-row and intra-row spacing on the growth, yield components and yield of chickpea variety at Haramaya District at main season. The treatment consisted one chickpea variety namely Habru, three inter- row (20, 30 and 40 cm) and four intra- rows spacing (5, 10, 15 and 20 cm). The experiment was laid out...
Abstract: Bread wheat is one of important food crop in the study area, but its productivity is limited by poor soil fertility. Thus, the study was conducted to investigate the effect of blended NPS fertilizer rates on yield and yield-related traits, nutrient use efficiency and grain quality of bread wheat varieties and assess their economic feasibility. Factorial combination of three bread wheat varieties (Senate, Mandoyu and Local) and six fertilizer rates (0, 50, 100, 150, 200, and 250 kg ...
Abstract: Potato (Solanum tuberosum L.) is one the most important food and cash generating crops in the eastern parts of Ethiopia, particularly East Harerghe zone, where it is grown three times per year. However, the average yield of potato is low, due to low soil fertility and poor ferti lizer management practice. Therefore, a field experiment was conducted in 2021 at Damota, Haramaya district, with the objectives of assessing the influences of integrated use of Farm yard manure and NPS ble...
Abstract: Sugarcane (Saccharum officinarum l.) is an important industrial crop that is used for sugar production in Ethiopia. However, the yield and yield component of sugarcane crop is limited by lack of site-specific appropriate agronomic practices related to fertilizer management in Ethiopia. The effects of new blended NPS fertilizer optimum rate specific to sugarcane variety was not known at study area. Therefore, a field experiment was to assess the effects of blended NPS fertilizer rat...
Abstract: Black cumin (Nigella sativa L.) is one of the most important spice and medicinal herb which is produced mainly by smallholder farmers in Ethiopia. However, the seed yield of the crop is low due to a number of constraints out of which low soil fertility, random plant spacing, and sowing of the seeds by broadcasting are the major ones. Therefore, field experiments were conducted in Ambo and Dandi districts in West Shewa Zone of Central highlands of Ethiopia to investigate the effect ...
