						 Onion is an important  vegetable crop, which has produced worldwide including of Ethiopia for its daily uses and economic  benefits. Under the scarcity of irrigation water, the need to use the available water economically and efficiently is unquestionable.  Deficit irrigation improves water use efficiency, by maintaining soil moisture content below optimum level  throughout the growing season. The objective  of this study was to study the effect of onion yield response to  irrigation level during low and high sensitive  growth stages and bulb quality  under semi-arid climate  conditions. An experiment was conducted for three consecutive seasons to investigate the effect of water stress  imposed at different growth stages on bulb yield and water productivity of onion (Allium cepa L.). This was  mainly related to low adoption of onion production package. The objective  of this .. Read More»
