Phenology and crop stand are the important determinant which fix crop growth cycle and directly or indirectly affect crop productivity. In Pakistan, the conventional tillage practices are used for the production of wheat since long ago. The present concern about the environmental pollution due to the intensive tillage practices and high inorganic fertilization is an important issue. Field experiments were conducted at Agricultural Research Farm of NWFP Agricultural University Peshawar Pakistan during winter 2005-07 in Randomized Complete Block (RCB) design with split plot arrangement having three replications. Twelve treatments of N, farmyard manure (FYM) and soybean residue (SR) management were arranged in subplots and three tillage practices [deep tillage (DT), conventional tillage (CT) and minimum tillage (MT)] in main plots. The objective of this study was to investigate the effects of N sources under different tillage systems on wheat.
