ABSTRACT
The study was conducted at the National Agricultural Research Centre, Islamabad to assess the effects of different combinations of fertilizer nitrogen (N) and phosphorous (P) with or without farm yard manure (FYM) on yield, yield components and as well as on the grain quality parameters of wheat. Nutrient treatments included full fertilizer NP (100:100:00), full fertilizer NP + FYM (100:100:20), half- fertilizer NP (50:50:00), half- fertilizer NP + FYM (50:50:20), FYM only (00:00:20) and control (00:00:00). N & P were applied in kg ha-1 and FYM in t ha-1. Wheat variety, Chakwal-86 was planted in randomized complete block design (RCBD) with four replications. Because of different combinations of fertilizer NP and FYM, statistically significant differences in biological yield, grain yield and yield components of wheat were recorded. Maximum wheat grain yield of 4083 kg ha-1 was obtained with the application of full fertilizer and FYM. Minimum grain yield and biological yield were recorded with no fertilizer and only FYM application. Different combinations of fertilizer NP with and without FYM did not have any significant effect on quality parameters i.e., test weight, PSI and percent flour yield.
