Effect of different sources of fertilizers on the yield and yield components of wheat variety kohat-2000 under rainfed conditions of kohat during 2012

Experimental site had pH value of 7.44 with electrical conductivity of 0.14 dS/cm. Soil was alkaline, strongly calcareous (21.25% CaCO3), deficient in organic matter, nitrogen & phosphorus and adequate in potassium. It has no problem of salinity and is clay loam in texture. The grain yield was significantly increased due to different fertilizer combinations. The highest grain yield of 2133 kg ha -1 was recorded by applying Nitrophos+UREA+K2SO4 @ 90-60-30 kg ha -1 followed by 1933 and 1900 kg ha -1 obtained by applying DAP+ Ammonium sulfate+ Potassium
