Abstract: Climate variability affects crop productivity at both global and local scales, and adaptation of agricultural practices against this variability helps to translate perception of the farmers to decision-making process. This study was initiated to analyze climate variability, examine its effect on maize productivity, and assess perception and adaptation strategies of smallholder farmers to climate variability in West Badawacho District. Climate and crop data from 2000-2019 were colle...

TECHNICAL EFFICIENCY IN TEFF PRODUCTION: THE CASE OF SMALLHOLDER FARMERS IN JAMMA DISTRICT, SOUTH WOLLO ZONE, ETHIOPIA

Abstract: Teff is one of the dominant crops and its productivity is low in the study area. This means that it is possible to obtained additional output from existing inputs used, if resource are properly used and efficiently allocated. The aim of this study was to determine the level of technical efficiency of smallholder teff producers and identify factors affecting technical efficiency of smallholder farmers in teff production of Jamma district, South Wollo Zone, Ethiopia. A three-stage sa...

EFFECT OF MUNGBEAN (Vigna radiata (L.) Wilczek) INTERCROPPING ON EARLY GROWTH OF SUGARCANE (Saccharum officinarum L.) UNDER IRRIGATION AT METAHARA SUGAR ESTATE, ETHIOPIA

Abstract: Appropriate planting pattern and suitable variety of mungbean are important agronomic practices to increase the productivity of mungbean and sugarcane. Hence, a field experiment was conducted from June to August 2018 at Metahara Sugar Estate under irrigation to evaluate the performance of mungbean varieties intercropped in different planting patterns with sugarcane varieties; and to assess the effect of intercropped mungbean varieties on early growth and development of the associat...

EFFECT OF INTRA-ROW SPACING AND IN-SITU MOISTURE CONSERVATION ON YIELD COMPONENTS AND YIELD OF MAIZE (Zea mays L.) AT JIGJIGA, EASTERN ETHIOPIA

Abstract: Realizing the importance of developing appropriate cultural practices for maize in Jijjiga area, a study was conducted for one season in 2016 with the objectives to (1) assessing the effect of intra-row spacing and in-situ moisture conservation methods on yield components and yield of maize; and (2) estimate the economically feasible intra-row spacing and in-situ moisture conservation methods for higher productivity of maize. Three intra-row spacing (20, 25 and 30 cm) and four in-s...

EFFECT OF BLENDED NPS AND N FERTILIZER RATES ON YIELD COMPONENTS, YIELD AND GRAIN PROTEIN CONTENT OF BREAD WHEAT (Triticum aestivum L.) IN BORE DISTRICT, GUJI ZONE, SOUTHERN ETHIOPIA

Abstract: Bread wheat is a major cereal crop in Ethiopia and in the study area, but its yield is limited due to minimum use of improved varieties, diseases, weeds, low soil fertility and lack of location specific fertilizer recommendation. Therefore, a field experiment was conducted during the 2016 main cropping season at Bore Agricultural Research Center to evaluate the effect of blended NPS and N fertilizer rates on yield components, yield and grain protein content; and to determine econom...

EVALUATION OF BRACHIARIA (urochloa) CULTIVARS FOR AGRONOMIC PERFORMANCE, FORAGE YIELDS AND CHEMICAL COMPOSITION AT DIFFERENT HARVESTING STAGES

Abstract: A study was carried out at Haramaya University ‘Rare’ site to Evaluate the agronomic performance, forage yields, and chemical composition of three Cultivars of Brachiaria (Xaraes, Piata, and Basilisks) at three harvesting stages (60, 90 and 120 days). The experiment was conducted by 3*3 factorial arrangements in a randomized complete block design (RCBD) with three replications. The plot size was 4 m * 3 m (12 m2 ) with a total land area of 44 m * 15 m (660 m2 ). Data were analy...

Response of Sugarcane (Saccharum Spp. Hybrid) Varieties to the Application of Chemical Ripeners at Kessem, Metahara, and Wonji-Shoa Sugar Estates in Central Rift Valley of Ethiopia

Abstract: Ripening management is one of the core practices in sugarcane production to boost the sucrose content. Conventionally, in Ethiopian Sugar Industry, withholding irrigation through drying off the cane prior to harvesting is commonly conducted to facilitate the improvement of sucrose content. However, this method of ripening lacks accurate control of crop water supply and there is risk related to reduction in sugarcane and sucrose yield resulting from excessive withholding of water. C...

EVALUATION OF CROPPING SYSTEMS THROUGH OPTICAL SENSOR MONITORING AND SOIL MOISTURE MEASUREMENT IN MAIZE BEAN CROP

Abstract: Maize-legume cropping systems are practiced under conventional practice (CP) which has resulted in soil degradation and frequent crop failure, which may be slowed or reversed with conservation agriculture (CA). Traditional plant tissue sampling and analysis is time taken and destructive method; whereas optical sensor techniques in particular, normalized difference vegetative index (NDVI) are an instantaneous, non-destructive, and quantitative assessment. CA can improvesoil health a...
