Abstract
The present investigation entitled âEffect of Integrated Weed Management on growth and yield of maize (Zea mays L.)â was conducted at the Crop Research Centre, ITM University, Gwalior (M.P.). Maize (Zea mays L.) is the worldâs widely grown cereal crop and primary staple food crop in India and many developing countries. Control of weeds from the fields of maize is, therefore, very essential for obtaining good crop harvest. Hence weed control in developed countries is done by using herbicides. Herbicides weed control is an important alternative to manual weeding because it is cheaper, faster and gives better weed control. There is a great potential of increasing its yield of maize varieties with high yield potential are under cultivation yet the average yield is still far below as compared to achievable potential of varieties. The experiment was laid out in the Split Plot Design with three replications. Each replication was comprised of twelve treatments consisting of three varieties (viz., SWAD, ZM 8 and Jawahar Makka-215) in main plot and different weed control treatments (viz., Control, Atrazine, 2 4-D and Hand weeding) in sub plot. Result concluded that the different weed control treatments were significantly diminishing the weeds under experimental filed of maize. It was recorded that the variety V 3 (Jawahar Makka-215) was significantly superior variety of maize as compared to the rest of varieties. It was recorded that the weed control W 1 (Hand weeding at 20 & amp; 40 DAS) was found the best treatment among all weed control treatments. Treatment W 2 (Atrazine at 1.0 kg ai ha -1 (PE) + Hand weeding at 40 DAS) was superior to control narrow leaf weeds, while the treatment W 3 (2, 4 D at 1.0 kg ai ha -1 (POE) + Hand weeding at 40 DAS) was the best treatment to control broad leaf weeds in maize.
