Effect of weed management practices on yield attributes and yields of sweet corn

Abstract

The experiment was carried out during rabi season of 2016 at Research Cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh). Maize has been an important cereal because of its great production potential and adoptability to wide range of environments. In Indian agriculture, maize assumes a special significance on account of its utilization as food, feed and fodder. The maximum plant height, number of green cobs, cob weight, highest length of cobs, number of rows cob-1 and number of grains row-1 were observed under atrazine 1.25 kg a.i. ha-1 (PE). The highest green cob yield of maize was obtained under atrazine 1.25 kg a.i ha-1 PE followed by one hoeing and lowest in the weedy check. Whereas, the maximum grain cob-1 was recorded under hand weeding twice.
