Abstract:
Wheat is the most extensively grown food crop and a staple food for the majority of the world's population. At the same time, wheat is the most reliable crop in the country and is necessary for the country's nutritional security. But, one of the primary factors limiting wheat output and productivity is weed infestation. Weeds in crop fields not only compete with standing crops for nutrients but also for light, water, air, space and micro environment and thus, reduce the quantity and quality of agricultural produce. Weeds can reduce yields to a greater extent depending on the density and dynamics of the weeds. Effective weed management plays a crucial role for the growers aiming at minimizing labour demand and production costs. It can be achieved through adopting integrated weed management (IWM) in which weed flora population can be eliminated by using various suitable management practices against weeds i.e. hand weeding, mulching, hoeing or integration of herbicide can control weed effectively during critical period of crop weed competition. Considering all these facts this article summarizes effect of tillage and herbicides on weed growth and yield of wheat.
