ABSTRACT
Integrated use of organic and inorganic fertilizers enhances wheat productivity. This research was conducted on integrated management of fertilizer nitrogen and poultry manure for wheat improvement at New Developmental Research Farm, Khyber Pakhtunkhwa Agricultural University, Peshawar in 2010-11. Three levels of fertilizer nitrogen (75, 100 and 125 kg ha-1) and two poultry manure levels (0 and 4 tones ha-1) were allotted to main plot while time of fertilizer nitrogen application were as: full at land preparation, full at boot stage and ½ at land preparation + ½ at boot stage, to the subplot. Poultry manure was incorporated into the soil at the time of land preparation. Compared to 75 and 125 kg/ha, inorganic nitrogen rate of 100 kg ha-1 produced more productive tillers m-2 (238), increased leaf area (27.87 cm2), grains spike-1 (42), thousand grains weight (48.38 g), biological yield (7244 kg ha-1), grain yield (2644 kg ha-1) and harvest index (36.30 %). More productive tillers m-2 (5.4%), leaf area (6.7%), grains spike-1 (5%), 1000 grain weight (4.4%), biological yield (5.8%), grain yield (16.7%) and harvest index (11.2%) were observed in PM incorporated plots compared to control. Optimum population of productive tillers (239), wider leaf area (27.9 cm2), more number of grains per spike (43), thousand grains weight (48.85 g), biological yield (7147 kg ha-1), grain yield (2701 kg ha-1) and harvest index (37.82%) resulted from split application of inorganic N in comparison to both early and late full applications. Thus, the use of 100 kg N ha-1 as half at sowing and half at boot stage with poultry manure incorporation is recommended for improving growth, yield and yield components of wheat.
