Abstract:

Wheat is the most important staple cereal crop in most parts of Ethiopia.However, appropriate management practice that combines improved varieties and NPS fertilizer is lacking in Gewane. Thus, field experiment was conducted from November 2018 to February 2019 to assess the effects of NPS fertilizer rates on growth, yield components and yield of bread wheat varieties; and to evaluate the cost-benefit of NPS fertilizer rates for production of bread wheat under irrigation at Gewane Afar region. Factorial combinations of three varieties (Fentale, Lucy and Werer-2) and five levels of NPS fertilizer (0, 50, 100, 150 and 200 kg ha-1) were used in randomized complete block design with three replications. The results showed that the main effect of NPS fertilizer rates and varieties were highly significant on all phenology and growth parameters except days of 50% heading which was significant at NPS fertilizer alone. Similarly the main effect of NPS fertilizer rates and varieties were highly significant on all yield components but grain yield showed significant interaction (p
