Abstract: Wheat is the most important staple cereal crop in most parts of Ethiopia.However, appropriate management practice that combines improved varieties and NPS fertilizer is lacking in Gewane. Thus, field experiment was conducted from November 2018 to February 2019 to assess the effects of NPS fertilizer rates on growth, yield components and yield of bread wheat varieties; and to evaluate the cost-benefit of NPS fertilizer rates for production of bread wheat under irrigation at Gewane A...
Abstract: Maize 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 ...
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: Intercropping is one of the intensive cropping systems which ensure sustainable utilization of limited land resources. Maize-common bean intercropping is often considered to be the best strategic cropping system to overcome the problems of adverse effects of shortage of rainfall. Cereal-legume intercropping is common in Ethiopia but intercropping of common bean and with maize (Zea mays L.) is a recent practice in maize based cropping system of many areas in Ethiopia. The objective ...
Abstract: Maize is becoming an important cereal crop in Ethiopia due to its use as sources of food security and generated income. However, its productivity is constrained by insufficient application of NPS fertilizer rate and different inter row spacing. Thus, afield experiment was conducted at Haramaya to assess the effects of application of different rates of blended NPS fertilizer and inter- row spacing on growth, yield components and yield of maize and to estimate the cost benefit analys...
Abstract: Groundnut (Arachis hypogaea L.) is one of the most important cash oil crops for smallholder farmers in semi-arid parts of eastern Ethiopia. However, its productivity is low due to biotic and abiotic stresses as well as poor agronomic practices. Suboptimal plant population and soil fertility depletion are among the major constraints to sustainable groundnut production in the semi-arid ecology of Ethiopia. This problem is aggravated by lack of application of fertilizers at appropriat...
Abstract: Bread wheat is one of the major crops in the study area cultivated both for home consumption and market purposes. However, its productivity is mainly constrained by poor soil fertility and lack of site specific fertilizer (NPSB) recommendation. Therefore, field experiment was carried out to assess the effect of blended NPSB fertilizer rates on yield, and yield related traits on selected bread wheat cultivars during the 2018/2019 cropping season on farmer training center (FTC) in Ke...
Abstract: Potato is an important food and cash crop in eastern Ethiopia including Oda Bultum District of West Hararghe Zone. However, there is no information on the role of blended NPSB fertilizer required to produce tuber yield and tuber quality traits of potato varieties in Oda Bultum District. A field experiment was conducted in Oda Bultum District, under rainfed during 2018 cropping season, with the objectives of assessing the effects of blended NPSB fertilizer rates on yield-related tra...
Abstract: Nitrogen and phosphorus deficiency are the most important production constraint of maize next to moisture deficiency. Therefore, a field experiment was conducted at Haramaya University main campus research station (Rare), eastern Ethiopia, using a maize hybrid xv variety (BH 661) as a test crop in the 2015 cropping season. The objectives of the study were to investigate the effects of nitrogen and phosphorus fertilizer application on growth, yield components and yield of the maize ...
Abstract: Nitrogen fertilizer is a major input required for cereal crop production in Ethiopia and its efficient use is important for the economic sustainability of cropping systems. Furthermore, the dynamic nature of N and its susceptibility for loss from soil-plant systems creates a unique and challenging environment for its efficient management especially on Vertisols. Developing suitable nitrogen fertilizer management practices is important strategy to improve productivity, quality and n...
Abstract: Faba bean (Vicia faba L.) is an important legume grown in the highlands of Ethiopia. However, the yield of the crop is limited by a number of edaphic constraints out of which low soil fertility, low pH and reduced N2 fixation due to various biological and environmental factors are the major problem. Therefore, a field experiment was conducted at Bore Agricultural Research Center under rain-fed condition during the 2015 main cropping season to evaluate effects of Rhizobium inoculati...
Abstract: Soybean [Glycine max (L) Merrill] is among the most important legume crops produced in western Ethiopia. However, declining soil fertility as well as poor soil fertility management practices has limited its yields. A field experiment was conducted in Bako Agricultural Research center during 2018 main cropping season to investigate the effect of NPS rates on yield and yield components of soybean varieties and to identify economically feasible rates of blended NPS rate that increase ...
Abstract: Common bean is one of the most important food and export pulse crop in Ethiopia. However, its yield is limited by a number of constraints, which include poor agronomic practices such as low soil fertility management, inappropriate plant spacing, low and erratic rainfall and diseases. Hence, a field experiment was conducted at Yabelo during the 2018-2019 main cropping seasons to assess effect of rates of NPS fertilizer and inter row spacing on growth, yield components and yield of c...
Abstract: Optimum plant spacing and number of seedlings per hill are important agronomic practices for the productivity of rice. Hence, field experiment was carried out to assess the effect of plant spacing and number of seedlings per hill on yield components and yield of transplanted rice under irrigation at Werer, Middle Awash. Factorial combinations of 2 inter-row spacing (20 cm and 30 cm), 3 intra-row spacing (10 cm, 15 cm and 20 cm) and 3 seedlings (2, 3 and 4) per hill were laid out in...
Abstract: The study was conducted in three districts of Borana Zone, with the objective to determining the impacts of climatic factors and grazing on vegetation structure, herbaceous biomass yield and soil nutrients of Borana rangelands under traditional enclosure and continuous grazing rangeland types during end of growing season. Within both rangeland types of each districts 20 m x 20 m plots were placed at 200 m distances intervals with three replication used to collect woody vegetation a...
