Effect of seed rate and irrigation interval on yield components and yield of bread wheat (Triticum aestivum L.) at Mekane Selam district, South Wollo, Ethiopia

Abstract

Determination of optimum seed rate and planning suitable irrigation strategy are important practices to increase productivity of wheat under irrigation. Thus, a study was undertaken to determine the effects of irrigation intervals (5, 8, 11 and 14 days) and seed rate (75, 100, 125 and 150 kg ha-1) on yield components and yield of bread wheat during 2019 cropping season (November to April). Wheat variety ADEL-6 was used as test crop. The experimental design was split plot design with three replications using irrigation interval as the main plot factor and seed rate as sub-plot factor. Results showed that the interaction effect of irrigation interval and seed rate had highly significant (P
