Effect of Different Weed Management Practices on Growth and Economics of Green Gram (Vigna radiata L.) under the Medium Land Situation of Manipur

Background: Green gram is one of the oldest and third-most significant traditional pulse crop grown in India. Green gram growthand economics are mostly hampered by weeds, however these effects can be reduced by using appropriate weed control techniques. Methods: A field experiment entitled “Growth, yield and nutrient uptake of green gram (Vigna radiata L.) as influenced by weed management practices under medium land situation on manipur” was conducted at Agronomy Research Farm, College of Agriculture, Central Agricultural University, Imphal, Manipur during Kharif season 2023-24. The experiment was consist of Nine treatments in randomized block design (RBD) replicated thrice. Result: The result revealed that T8: hand weeding at 20 and 35 DAS recorded higher growth parameters like plant height, fresh and dry weight of plant, number of nodules plant-1, fresh and dry weight of nodules plant-1 leaf area index (LAI), crop growth rate (CGR), relative growth rate (RGR) and net assimilation rate (NAR) which was statically at par with T4: Oxyflurofen @ 150 g/ha (PE-2DAS) + Hand weeding (35 DAS). While, maximum net return (104373.98) and B: C ratio (2.22) was found under the treatment T4 (Oxyflurofen @ 150 g ha-1 (PE- 2 DAS) + Hand weeding 35 DAS).
