Effect of Integrated Weed Management Practices in rabi Groundnut on Nutrient uptake by Crop and Nutrient Removal by Weeds

Abstract:

A field experiment was conducted to study the effect of integrated weed management practices on nutrient uptake by groundnut and nutrient removal by weeds at College of Agriculture, Professor Jayashankar Telangana State Agricultural University, Hyderabad, during rabi 2020-21. The experiment consisted of ten treatments laid out in randomised block design replicated thrice. Among all the weed management practices, the highest nutrient uptake by crop and lowest removal of nutrients by weeds were recorded with intercultivation fb hand weeding at 20 and 40 DAS. Among herbicides, pre-emergence application of diclosulam at 26 g ha-1fb intercultivation at 20 DAS in sandy loam soils and next best option was the pre emergence application of imazethapyr + pendimethalin at 960 g ha-1 fb intercultivation at 20 DAS.
