Abstract:

Studies on methods of weed control in rainfed maize were carried out on farmer's fields in Islamabad Capital Territory (ICT) of Pakistan during 1986 and 1987. The weed control methods were use of primextra and two "seeling", (Mechanical method). The data at harvesting were recorded on plant population, total number of cobs and fodder and grain yields. Application of primextra @ 0.5 kg. a.i/ha + one "seedling", proved to be the most productive as it gave highest grain yield (2097 kg/ha). The yield (1674 kg/ha) in plots treated with two "seelings" was significantly lower than the chemical as well as chemical + mechanical methods which gave net benefit of Rs. 1054 and Rs. 1097/ha over mechanical method alone.
