Response of Common Bean (phaseolus vulgaris l.) Varieties to rate of Blended NPS Fertilizer in Jarso District, East Hararghe.

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 ...

The Objective of the experiment was to investigate the influence of inter and intra-row spacing on yield components and grain yield of maize in 2019 cropping season at Chinaksen, East Hararghe Zone, eastern Ethiopia. The experiment was arranged in ...

Determination of Crop Water Requirement and Crop Coefficient at Different Growth Stage of Lowland Bread Wheat (Triticum aestivum L.) at Melkassa, Oromia, Ethiopia

Abstract: Accurate estimation of crop water requirements is crucial for better water-use efficiency and better planning of irrigation water resources. A crop water requirement is estimated using 'Kc ETo' approach. However, locally determined Kc information is not available for many crops in Ethiopia. In view of this, an experiment was conducted to determine the crop water requirement and crop coefficient of wheat during cool cropping season from lysimeter study. The study was carried out at ...

Effect of Plant Spacing on Yield and Yield Components of Common Bean (Phaseolus Vulgaris L.) Varieties at Haramaya, Eastern Ethiopia.

Abstract: The productivity of common bean (Phaseolus vulgaris L.) is low due to the use of inappropriate inter and intra row spacing in the study area. Thus, a field experiment was conducted at Haramaya, in the main rainy season ‘season of 2019 to assess the effects of plant spacing on Yield and Yield Components of common bean (Phaseolus vulgaris L.) at Haramaya, Eastern Ethiopia. The treatments consisted of two common bean varieties, (Haramaya and Babile), three inter-row spacing (30 cm, ...

Effect of Blended NPS and Urea Fertilizer Rates on Yield and Yield-Related Traits of Potato (Solanum tuberosum L.) at Haramaya, Eastern Ethiopia

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 ...

Effects of Blended NPS Fertilizer Supplemented With Nitrogen on Yield and Yield Components of Maize (Zea mays L.) at Dilla, Southern Ethiopia

Abstract: Maize is one of the most important cereal crops in Ethiopia. However, the yield of the crop is low mainly due to low soil fertility problems. Therefore, this study was conducted to identify the effect of blended NPS fertilizer supplemented with inorganic N and to estimate the economically feasible fertilizer rate for higher yield of maize. The experiment consisted of four levels of NPS fertilizer (0, 50, 100 and 150 kg ha-1) each supplemented with four levels of N (0, 32, 64 and 96...

Effects of NPS Fertilizer Rates on Growth, Yield Components and Yield of Bread Wheat (Triticum aestivum L.) Varieties under Irrigation at Gewane, North-eastern Ethiopia

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...

Effect of Different Tide Ridge Planting Methods and Variety on Yield Components and Yield of Maize (Zea Mays L.) at Haramaya, Eastern Ethiopia

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 ...

Factorial combination of three imp...

Effect of Maize and Common Bean Intercropping Pattern on Yield and Yield of the Components of Intercrops and Productivity of the System at Fafan, Somali Region, Eastern Ethiopia

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 ...
