Abstract:
An experiment trial was conducted at the Agricultural College and Research Institute in Killikulam during the summer crop of 2021-2022. treatments using a different range of weed control methods. According to this experimental, minimum weed density and weed dry weight, maximum weed control efficiency was achieved in rice + Dhaincha 1:1 ratio fb 2, 4-D at 25 DAS (Brown manuring) and mechanical weeding (MW) at 45DAS. Dhaincha intercropping, when combined with brown manuring, reduces weed growth while increasing rice crop growth and yield. Nitrogen has the greatest impact on rice production. Different levels of nitrogen application are followed to find the difference in crop growth reported by (Subramanian et al., 2021). RDF Nitrogen at 4 splits 20% at 15 DAS, 30% at AT, 30% at PI, and 20% at Flowering increases the growth and yield in aerobic rice. Therefore, two crucial management parameters that affect aerobic rice yield are nitrogen and weed management.
