Effect of Enhanced n and p Fertilizer with Chicken Manure on Growth and Yield of tow Wheat (Triticumaestivum L.) Cultivars at New Halfa Scheme

A field experiment was conducted for two consecutive winter seasons (2017/2018 and 2018/2019) at Shebaik site of New Halfa Scheme. The experiment arranged in (RCBD) with three replications was designed to study the Effect of amended N and P fertilizers on Performance and yield of two wheat cultivars: Bohain (B) and Debera (D). The six fertilizers levels was designated as 0N0P, M, M1N, M2N, M1P and M2P, corresponding to control (0kg/ha), 4 ton of chicken manure without or with 43,86kgN/ha and 43,86kgP/ha, respectively. Characters studied included: (leaf area(cm2) and shoot biomass(g) plant-1, number of yielded tillers plant-1, spike length, and grains spike-1, grain yield (g)plant-1,1000-grain weight(g, grain and harvest index.Generally, Debera cultivar (D) gave the heavier plants, highest number of tillers, longest spikes, higher number of grains plant-1 and grain yield. The results showed that, application of chicken manure together with high N,P levels significantly increased all growth and yield attributes. The highest grains yield/ha (7615.7, 7615.6 kg/ha) were recorded due to sowing Debera and application of (M2N and M2P). Therefore, wheat cultivar Debera may be grown under the application of 86kg N or P with combination of chicken manure in the agro-ecological conditions of Shebiak at northern region of NewHalfa Scheme.
