Nitrogen Uptake and Quality Parameters in Groundnut [Arachis hypogaea (L.)] Influenced by Different Weed Management Practices under Arid Zone of Rajasthan, India

The field experiment was conducted at Agricultural Research station, Mandor, Agriculture University, Jodhpur during kharif, 2019 to evaluate nitrogen uptake and quality parameters as influenced by different weed management practices in kharif groundnut. laid out randomized block design (RBD) with thirteen treatments of replicated thrice. Results revealed that weed-free treatment found significantly higher total crop, protein content kernel, oil out-turn lowest amount removal weeds compared weedy check. Among the herbicidal treatments, application pendimethalin + imazethapyr 1.0 kg/ha one manual weeding 30 DAS recorded crop (240.8 kg/ha), kernel (25.8%), (1214.7 kg/ha) (0.4 which closely followed (PE) 75 g/ha 20 DAS, quizalofop-p-ethyl 50 DAS.
