GENETIC VARIABILITY AND ASSOCIATION AMONG AGRONOMIC CHARACTERS IN SOME GENOTYPES OF MAIZE ( Zea mays L.) GROWN IN MAYICHOW, NORTHERN ETHIOPIA

Abstract: A total of sixteen barley (Hordeum vulgare L.) genotypes were evaluated for genetic variability and character associations at two different environments. The genotypes were grown in a simple lattice design. Data were collected on 16 morpho-agronomic characters. The analysis of variance at each location showed significant (P< 0.05) difference for all of the characters, except spikelets per spike gonder This indicated the existence of variability and hence the potential for selection...

EFFECT OF DEFICIT IRRIGATION LEVELS AT DIFFERENT GROWTH STAGES ON YIELD AND WATER PRODUCTIVITY OF ONION (Allium cepa L.) AT RAYA AZEBO WOREDA, NORTHERN ETHIOPIA

Abstract: Scarcity of water is the most severe constraint for development of agriculture in arid and semi-arid areas. Under such conditions, the need to use the available water economically and efficiently is indisputable. The important strategy for increasing water productivity and improving water use efficiency in the area of water scarcity, was deficit irrigation. A field experiment was conducted at Mehoni Agricultural Research Center during off season aimed at investigating the effect of...

RESPONSE OF MAIZE TO RATES AND TIMING OF NITROGEN FERTILIZER APPLICATION AND SUPPLEMENTARY IRRIGATION IN HARAMAYA DISTRICT, EASTERN ETHIOPIA

Abstract: Maize (Zea mays L) is an important food security crop widely grown in Hararghe Zones, eastern Ethiopia. However, the average yield of the crop is low due to several biotic and abiotic production constraints, among which low soil fertility and moisture stress are the major factors. As a result, three field experiments were conducted in the Haramaya District during the 2019/20 and 2020/21 main cropping seasons. The first objective was to investigate the response of two hybrid maize v...

EFFECT OF NITROGEN FERTILIZER AND HARDENING SEEDLINGS ON FRUIT YIELD AND YIELD RELATED TRAITS OF HOT PEPPER (Capsicum annum L.) AT AGARFA, SOUTH - EASTERN ETHIOPIA

Abstract: Hot pepper is an important spice and vegetable crop in Ethiopia, but its productivity is low due to poor agronomic practices including inappropriate nutrient supply and poor seedling management before transplanting. Therefore, a field experiment was conducted on the demonstration field at Agarfa Agricultural Technical Vocational and Education Training (ATVET) College in Bale Zone, south-eastern Ethiopia to evaluate the effects of nitrogen fertilizer and hardening seedlings on fruit...

Effect of Inter and Intra Row Spacing on Yield Components and Yield of Maize (Zea Mays L.) at Chinaksen, Eastern Ethiopia

Abstract: Maize production plays vital role for the producers of the study area in serving as staple food. However, its productivity is constrained by a number of factors out of which optimum spacing is among the most important production factors. 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 ...

Abstract: A field experiment was conducted inBabile District during the main cropping season of 2019 to evaluate the effect of plant spacing (inter- and intra-row spacing) on yield and yield related traits of sorghum (Sorghum bicolor(L.)Moench].Four inter-row spacing (65 cm,75 cm,80 cm and 90cm) and four intra-row spacing (15, 20, 25 and 30 cm ) were evaluated as treatments using a randomized complete block design with three replications. Yield and yield related parameterswere collected and ...

Effects of Blended NPSB Fertilizer Rates on Growth, Yield Components and Yield of Bread Wheat (Triticum asetivum.L) Varieties at Degam District, Central Ethiopia

Abstract: Bread wheat (Triticum aestivum L.) is an important food crop and source of income for farmers at Degam district in central highland of Ethiopia.

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 ...
