The field study was conducted at Haro Sabu Agricultural Research Center, during 2018 with the objective of assessing the effects of varieties and relative planting date of climbing common bean intercropping with maize on yield and yield related traits of the component crops and productivity of the system. The experiment was laid out in Randomized complete Block design...

EVALUATION OF EARLY MATURING SORGHUM [Sorghum bicolor (L.) Moench] AND COWPEA [Vigna unguiculata (L.) Walp.] VARIETIES INTERCROPPING ON GRAIN, STOVER, HERBAGE YIELDS AND NUTRITIVE VALUE IN FE

Abstract: The shortage of arable land and shortage of livestock feed are major constraints in East Hararghe Zone. Thus, a field study was conducted to evaluate early maturing sorghum varieties and cowpea varieties intercropping for both food and feed production at Fedis Agricultural Research Center, eastern Ethiopia in 2018 cropping season. With a total of 11 treatments; Two cowpea varieties (9333 and 9334) and three varieties of early maturing sorghum (Teshale, Birhan and Melkam) and their ...

EFFECT OF VETCH INTERCROPPING AND HARVESTING STAGES ON MORPHOLOGICAL CHARACTERISTICS, DRY MATTER YIELD, AND CHEMICAL COMPOSITION OF BRACHIARIA GRASS (Urochloa)

Abstract: This study was conducted at Haramaya University ‘Rare’ research site with an objective to determining the effects of intercropping vetch and harvesting stages on morphological characteristics, dry matter yield and chemical composition of brachiaria grass using a three factor factorial in RCBD with three replications. The three factors were 1) harvesting stages (HS) with five levels: 60, 90 and 120 day, 60 and 90 day of regrowth, 2) five-levels of intercropping: sole basilisk, s...

EFFECT OF NPS AND CHICKEN MANURE ON POTATO (Solanum tuberosum l.) GROWTH, YIELD COMPONENT AND YIELD AT HARAMAYA, EASTERN ETHIOPIA

Abstract: In Ethiopia, potato ranks first among the major tuber crop in the volume of production and consumption. However, the national average yield is 13.8 tons ha-1, which is very low, due to low soil fertility and poor fertilizer management practices. Field experiment was conducted in 2019/2020 main cropping season at Haramaya University research site. The objectives of the experiment were to assess the influences of integrated use of chicken manure and NPS fertilizers on growth, yield c...

RESPONSE OF COMMON BEAN (Phaseolus vulgaris L.) VARIETIES TO RATES OF BLENDED NPS FERTILIZER IN ADOLA DISTRICT, SOUTHERN ETHIOPIA

Abstract: Low soil fertility is one of the production constraints of common bean in the study area. Hence, a field experiment was conducted in Adola sub-site of Bore Agricultural Research Centre during the 2016 main cropping season to assess the effect of blended NPS rates on the yield and yield components of common bean varieties and to identify economically feasible rates of blended NPS that increase the productivity of the common bean varieties. The factors studied were six rates of blend...

RESPONSE OF WHEAT (Triticum aestivum L.) VARIETIES TO PHOSPHORUS FERTILIZER RATES AT SHASHEMENE, ETHIOPIA

Abstract: Optimum rate of phosphorus fertilization and use of adaptable variety are important factors in increasing grain yield. Thus, study on the response of wheat varieties to phosphorus fertilizer rates was conducted in 2015 main cropping season at two locations in Shashemene district of Oromia, Ethiopia. The objective was to determine the economically feasible rate of P fertilizer and to assess the effect of P on yield components and yield of wheat varieties. The treatments were three b...

RESPONSES OF TEF [Eragrostis tef (Zucc.) Trotter] VARIETIES TO BLENDED NPSB FERTILIER RATES AT GELAN, CENTRAL ETHIOPIA

Abstract: Tef is the major crop grown in Ethiopia and the study area. However, its productivity is low mainly due to limited use of improved varieties and low soil fertility as result of intensive soil erosion and long history of cultivation. Therefore ,a field experiment was carried out on a farmer’s field at Gelan Akaki district during the 2018 main cropping season (from July to November 2018) to assess the response of tef varieties to blended NPSB fertilizer rates and to identify the ec...

PREVALENCE AND MANAGEMENT OF STRIGA (Striga hermonthica L.) AND ITS EFFECT ON PRODUCTIVITY OF SORGHUM [Sorghum bicolor (L.) Moench] IN EASTERN ETHIOPIA

Abstract: Sorghum grows in a wide range of agro-ecologies most importantly in the drought prone areas and is the main staple food crop in eastern Ethiopia. However, Striga hermonthica is the major constraint to sorghum production in the Striga-stricken or invaded areas. Thus, this research was conducted with the specific objectives to: (1) investigate the prevalence and socio economic impact of Striga infestation in sorghum growing areas; (2) evaluate the effect of moisture conservation prac...

EFFECTS OF CLIMATE VARIABILITY ON CROP YIELD, INCOME AND RURAL LABOR DISPLACEMENT IN CENTRAL ETHIOPIA

Abstract: Ethiopian smallholder farmers are the most vulnerable group of societyto the effects of climate variabilitybecause they have nature dependent economic system. This study examinedtheeffects of climate variability on five major cereals yield,crop income and rural labor displacementin thecentral highlands and Arsi grain plough farming systems of Ethiopia. The seven round unbalanced panel data (1994-2009) collected by Ethiopian Rural Household Survey from 15 kebeles of the seven farmin...

CROP PRODUCTIVITY, EFFICIENCY AND COMMERCIALIZATION OF SMALLHOLDER FARMERS IN THE HIGHLANDS OF EASTERN ETHIOPIA

Abstract: The agriculture sector is the most important segment in the Ethiopian economy. This is because of its contribution to the national GDP (38.5%) where crop accounted for 27.4%, and provides employment for 72.7% of the total population. Despite efforts made to commercialize and transform Ethiopian agriculture from subsistence to production of high value crops, the sector’s performance has been below expectations. In light of the problems and the research gaps identified, this study ...
