Effect of nitrogen and phosphorous application onyield and yield components of wheat (triticumaestivum l.), in three soils series at new halfa scheme

Afield Experiment was conducted for two consecutive winter seasons (2017-2018) and (2018-2019) at New Halfa Scheme in three of soil series (Asubri soil series at Hajir block, KashmAlgerba soil series at the Faculty Of Agric. Research Farm) and Sabaat soil series at Shabik block; to study effect of three levels of nitrogen(0,43 and 86 kg N/ha), and three levels of phosphorus (0, 40, 80 Kg P2O5/ha) on yield of wheat (Debera cultivar). The experiment was arranged in Randomized Complete Block Design (RCBD) with three replications at each location in both seasons. characters studded include (spike length, number of grains/Plant, ,1000- grain weight, grains yield/ha, and harvest index). The results indicated that, increasing levels of nitrogen or phosphorus and their interaction increased the yield attributes. Across the three locations, the highest grain yield (3363.5kg/ha and 2609kg/ha) were obtained at shebaik and Faculty locations due to application of 2N2P treatment while 2N1P recorded the highest grain yield (32290.6kg/ha) at Hajer location. The positive effect of high N level and low level of P atHajer site on grain yield may be a key factor for wheat production under semi-arid environment. In conclusion, application of high N level together with phosphorus could enhanced wheat production in New Halfa Scheme.
