The effects of different spreader rates and fertilizer types on grain yields of barley (Hordeum vulgare L.)

Abstract

A field study was conducted to study the effects of three different spreader rates (170, 220 and 270 kg.ha-2) and two fertilizer types [NPK and DAP (Diammonium Phosphate)] on the yield of barley crop (plant height (cm), number of branches in plant (branch.plant-1), spike length (cm), number of seeds.plant-1 (seeds.plant-1), number of spike.m-2 (spike.m-2), 1000 kernel weight (g) and grain yield (t.ha-1)) by using a fertilizer spreader. The experiments were conducted in randomized complete block design (RCBD) with three replicates. The results of the study showed that the effects of the coefficients were ranged between significant and not significant concerning studied characteristics. It is recommended that using DAP fertilizer and 270 kg.ha-2 spreader rates to increase barley producing.
