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 ...

EFFECTS OF BLENDED (NPSB) FERTILIZER RATES ON YIELD AND YIELD COMPONENTS OF BREAD WHEAT (Triticum aestivum L.) VARIETIES IN HULBAREG DISTRICT, SOUTHERN ETHIOPIA

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...

EFFECT OF DIFFERENT TIDE RIDGE PLANTING METHODS AND VARIETY ON YIELD COMPONENTS AND YIELD OF MAIZE (ZEA MAYS L.) AT HARAMAYA, EASTERN ETHIOPIA

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...

EFFECT OF INTER- AND INTRA-ROW SPACING ON LINT YIELD, YIELD RELATED TRAITS AND FIBER QUALITY OF COTTON (Gossypium hirsutum L.) IN MIDDLE AWASH, ETHIOPIA

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...

EFFECTS OF INTRA AND INTER ROW SPACING ON YIELD AND YIELD COMPONENT OF POTATO (Solanum tuberosum L.) IN KERSA DISTRICT, EASTERN ETHIOPIA

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...
