摘要

Tillage operation resulted in significant reduction in weed dry weight at all the growth stages and increased the grain yield over no tillage practice. The lowest weed dry weight and the highest grain yield in one season were recorded with 24 kg seedha~(-1). Hand weedings at 25 and 45 DAS recorded significantly higher grain yield and lower weed dry weight at silking and maturity stages. Maize is one of the most important cereals grown over diverse environments and has varied uses as food, feed and fodder. Rainy season maize suffers heavy yield loss due to severe crop-weed competition and the loss is further aggravated when weeds are not controlled within a specific period of time. Manual weeding is often difficult due to inadequate and non-availability of labour in time, higher cost and lack of workable field condition. In such situation, use of herbicides becomes an obvious choice, Competition for growth factors in favour of crop can also be exploited with favourable growth condition and by establishing optimum plant population. Considering the above views, the present investigation was planned to assess the effect of tillage, seed rate and weed control methods on weed growth and yield of kharif maize.
