RESPONSE OF WHEAT (Triticum aestivum L.) VARIETIES TO PHOSPHORUS FERTILIZER RATES AT SHASHEMENE, ETHIOPIA

Abstract:

Optimum rate of phosphorus fertilization and use of adaptable variety are important factors in increasing grain yield. Thus, study on the response of wheat varieties to phosphorus fertilizer rates was conducted in 2015 main cropping season at two locations in Shashemene district of Oromia, Ethiopia. The objective was to determine the economically feasible rate of P fertilizer and to assess the effect of P on yield components and yield of wheat varieties. The treatments were three bread wheat varieties (Danda’a, Kubsa, and Digalu) in main plot, and five P levels (0, 46, 92, 138, and 184 kg P2O5 ha-1) in subplot; in split plot design in three replications.
