Effect of Irrigation Interval, Nitrogen Fertilizer and Farmyard Manure on Wheat (Triticum aestivum L.) Yield in Elmultaga Soil Series Northern State, Sudan

Abstract

A field study was conducted for two cons successive winter seasons; 2016/17 and 2017/18, at the Research Farm of the National Institute of Desert Studies, New Hamdab Scheme, Northern State of Sudan. The objective was to investigate the effect of treatments interactions of irrigation interval (7, 10 and 15 days), application of Nitrogen fertilizer (43 and 86 Kg fed-1) and farmyard manure
(zero and 10ton ha-1) on wheat (Triticum aestivum L.) growth and yield in the area. The experimental design was a split-split-plot design with four replicates. The results showed no significant differences (P ≤ 0.05) on plant per meter square in both seasons and harvest index in the second season to significant differences (P ≤ 0.05) on plant height, spike length, number of seeds/spike, biological yield, straw yield in both seasons and harvest index season one. and highly significant differences (P ≤ 0.01) due to the interaction effect of these three factors on the number of spikes/m2, number of tillers/ m2, 1000 seeds weight and grain yield. The combination of 7 or 10 days irrigation interval, application of 86 Kg fed-1 nitrogen fertilizer and 10 ton ha-1 farmyard manure produced the highest means values of growth, yield and yield components of wheat in both seasons.
