Abstract

A field experiment was conducted for 2 consecutive winter (rabi) seasons of 2014–15 and 2015–16 at G.B. Pant University of Agriculture and Technology, Pantnagar to evaluate the effect of irrigation levels, planting methods and mulching on growth, yield, water-use efficiency, economics and nutrient uptake in yellow sarson {Brassica rapa (L.) var. trilocularis (Roxb.) Kitam}. Plant height, total dry matter, yield attributing characters, seed and stover yields, nutrient uptake by seed and stover, net returns and benefit: cost ratio were influenced significantly due to irrigation levels being the maximum at 1.2 IW/CPE ratio followed by 0.9 IW/CPE ratio. Higher water-use efficiency (WUE) was recorded with irrigation at 0.9 IW/CPE ratio, which was at par with 1.2 IW/CPE ratio. The maximum plant height, total dry matter, yield attributing characters, WUE and seed and stover yields, C assimilation and N uptake by seed and stover, net returns, B: C ratio were found with raised bed planting compared to flat bed planting. Yellow sarson sown with mulch produced significantly higher values of growth and yield attributing characters, seed and stover yields, WUE, nutrient uptake and economics compared to no mulch treatment.
