1.1 Background of the study
Agricultural sectors were the leading sector in Ethiopian economy, 47.7% of the total GDP compared to 13.3% for industry and 39% for services [The growing method and specific agronomic practices can considerably improve the quality and biological value of pepper fruits [Most of the farmers in central rift valley including the study area use traditional furrow irrigations with poor water management and irrigation practice. Shortage of irrigation water, erratic rainfall and short rainy season are problems to produce crops in the study area. The only Djido River, starting from the Silte zone mountainous area for irrigation of the site is highly utilized and used heavily by upper stream users. Therefore, these field experiments were conducted to examine the influence of deficit irrigation levels on the agronomic performance of pepper (➢ To evaluate the impact of deficit irrigation on growth, yield and water productivity of Pepper➢ To identify water stress threshold at different water deficit levels on Pepper under drip irrigation methods.
