Effect of nitrogen and sulphur nutrition on growth and yield of Indian mustard (Brassica juncea L.) in western UP

Author(s): Mukesh Kumar, PK Singh, KG Yadav, Ashutosh Chaurasiya and Ashok Yadav
Abstract: A field experiment was conducted to study the effect of nitrogen and sulphur nutrition on growth and yield of Indian mustard (Brassica juncea L.) in western UP during Rabi season of 2016 at Crop Research Centre (Chirori) of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.). The soil of the experimental field was well drained, sandy loam in texture and slightly alkaline in nature. It was low in organic carbon and nitrogen but medium in available phosphorus and potassium with an electrical conductivity (1:2, soil: water) of 1.65 dS/m. The experiment consisted of twelve treatment combinations with nitrogen and sulphur. The treatment consisted of four nitrogen levels (0, 40, 80 and 120 kg ha-1) and three sulphur levels (0, 20 and 40 kg ha-1) were tested in Factorial Randomized Block Design (RBD) with three replications. The mustard variety Pusa Bold was grown. The growth and yield, nutrient uptake as influenced by different treatments were assessed. Increasing levels of nitrogen from 0 to 120 kg N ha-1 caused significant increase in growth and yield attributes (plant height, LAI, branches plant-1, siliqua plant-1, seeds siliqua-1, 1000 seed weight) and yields (biological, seed and oil yield) of mustard crop and found maximum at 120 kg N ha-1. Similarly, application of 40 kg S ha-1gave maximum plant height, leaf area index (LAI), dry matter production, yield attributes, seed, stover yield, oil content and oil yield of mustard crop. The highest net returns of 48,006 and B: C ratio of 2.25 was obtained with the application 120 kg N ha-1than rest of nitrogen levels. With respect to sulphur levels, the highest net returns of 36,454 and B: C ratio of 1.65 was obtained with 40 kg S ha-1. Thus, the application of nitrogen at 120 kg N ha-1and sulphur at 40 kg S ha-1 found economical in obtaining higher yields with higher net return and B: C ratio.
