Abstract:

A field experiment was conducted at oilseed block of Norman E. Borloug Crop Research Center of G.B. Pant University of Agriculture and Technology, Pantnagar, U.S. Nagar (Uttarakhand) during rabi season of 2014-2015 to study the nitrogen requirements through foliar applications in mustard. The experiment was laid out in split plot design containing three nitrogen levels viz. recommended dose of nitrogen (120 kg ha-1), 75% of the recommended dose of nitrogen (90 kg ha-1), and 50% of the recommended dose of nitrogen (60 kg ha-1) in main plots; with four foliar sprays viz. single spray of water, single foliar spray of 2 % urea solution at 20 days after sowing (DAS), two foliar sprays of 2 % urea solution at 20 and 40 DAS and three foliar sprays of 2 % urea solution at 20, 40 and 60 DAS in sub plots, replicated thrice. The results revealed that the soil application of 75% of the recommended dose of nitrogen (90 kg ha-1) was found significantly superior over rest of the soil application treatments as in all the growth indices and the yield attributing characters like plant height, dry matter accumulation, number of branches, number of siliquae per plant, 1000 grain weight, oil content in seeds and ultimately resulted to higher yields (1463.6 kg ha-1) yield. Among the foliar sprays, two foliar sprays of 2 % urea solution at 20 and 40 DAS proved superior over rest of the foliar applications and recorded highest yield (1622.6 kg ha-1).
