Effect of Weed Management Practices on Nutrient Uptake and Economics of Mustard (Brassica juncea)

A field experiment was conducted during rabi season (November to February, 2020–21) at College Farm, of Agriculture, Rajendranagar, Hyderabad. The farm is geographically positioned 17°19’16.4” North latitude and 78°24’43” East longitude an altitude 542.3 m above the mean sea level. According troll’s climatic classification, it categorized under semi-arid tropics (SAT). experimental sandy loam texture with available nitrogen (223 kg ha-1), phosphorus (30.87 ha-1) potassium (375.72 ha-1). Mustard variety NRCHB-101 sown seed rate 4 ha-1. seeds were in solid rows 40 cm apart between a depth 3‒4 covered loose soil immediately after seeding. laid out randomized block design twelve treatments replicated thrice. data analyzed using standard statistical techniques. Among different weed management practices, higher nutrient uptake (59.57, 24.51, 52.46 ha-1 ) by crop observed intercultivation hand weeding 15 30 DAS on par Oxadiargyl 6% EC 0.09 PE fb DAS.
