Effects of Seeding and NPSB Blended Fertilizer Rates on Yield and Yield Components of Bread Wheat (Triticum aestivum L.) in Abay Chomen District, Horo Guduru Wollega Zone, Western Ethiopia

Abstract

Low soil fertility and poor crop management practices including use of inappropriate seeding rate are among the major constraints limiting the productivity of wheat in Ethiopia in general and in the study area in particular. Thus, the field experiment was conducted to enhance bread wheat productivity in the study area by determining the optimum seeding and NPSB blended fertilizer rates. Factorial combination of three levels of seeding rates (100, 125 and 150 kg ha -1 ) with five levels of NPSB blended fertilizer rates (0, 50, 100, 150 and 200 kg ha -1 ) were laid out in a Randomized Complete Block Design (RCBD) with four replications.
