Weed infestation ranked first as main constraint in agriculture production system because both weeds and crop striving for space, light, water and nutrients. For this purpose, a field trial was designed in CRBD across factorial management during 2017-18. Four different seed rates (100, 125, 150 and 175 kg ha-1) tested against weed management practices (no weeding, herbicide application, hand hoeing and allelopathic weed control) and replicated thrice. The results revealed that seed rate of 125 kg ha-1 increased grain yield (4.24 t ha-1). The wheat physiological traits were also improved on this seed rate with CGR (16.80 g m-2 day-1) and NAR (4.78 16.80 g m-2 day-1). This medium seed rate also increased
