Abstract
In Pakistan, maize (Zea mays L.) is grown following a wheat crop under conventional tillage practices since long ago. The present concern about the soil fertility degradation, soil erosion and environmental pollution due to the intensive tillage practices and high inorganic fertilization is an important issue. The objective of this study was to investigate the effects of various organic and inorganic nitrogen treatments under three tillage systems i.e., Deep tillage (DT), conventional tillage (CT) and minimum tillage (MT) on maize planted after wheat crop. Tillage significantly affected all parameters studied. Minimum tillage and CT proved superior in terms of emergence m-2, plant height, grains per cob
