Effect of weed management and nitrogen nutrition on biochemical and phenological parameters of Indian mustard [Brassica juncea (L.) Czern and Coss.]

Author(s): Sontara Kalita, SL Mundra and Naresh Kumar Sharma
Abstract:
A field experiment carried out during the rabi, 2014-2015 in Rajasthan College of Agriculture, Udaipur to study the effect of weed management and nitrogen application on Indian mustard [Brassica juncea (L.) Czern and Coss.]. The experiment comprising 15 treatment combinations consisted of 5 weed management practices and 3 nitrogen levels and was evaluated under factorial randomized block design with three replications. The results show that pre-emergence application of oxadiargyl 0.09 kg ha-1 recorded seed and oil yield (2234 and 899 kg ha-1) with the highest (2.67 mg g-1of fresh leaves) chlorophyll content among different herbicidal treatments which was comparable to one hand weeding. Among the nitrogen levels, application of both 75 and 60 kg N ha-1 resulted in significant increase in chlorophyll content, seed and oil yield of plant over 45 kg N ha-1.
