Effect of irrigation management and water conservation practices on growth and yields in yellow sarson (Brassica rapa L.) in Uttarakhand region

Field experiments were conducted for two consecutive rabi seasons during 2014-15 and 2015-16 at Norman E. Borlaug Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar to evaluate growth and yield parameters of yellow sarson (Brassica rapa L.) affected by different irrigation levels, planting methods and mulching. Significantly higher numbers of leaves per plant and dry matter accumulation in leaves and stem were reported at 1.2 IW/CPE ratio over 0.6 and 0.3 IW/CPE ratio in both the years of study. Seed yield of yellow sarson increased significantly up to 0.9 IW/CPE ratio as compared to remained irrigation levels. In both the years, yellow sarson planted on raised bed produced 11.5 and 7.1 per cent higher seed yield with higher number of leaves over flat bed planting method, respectively. Application of rice straw mulch recorded 11.7 and 12.3 per cent significantly higher seed yield than no mulch, respectively. | Effect of irrigation management and water conservation practices on growth and yields in yellow sarson (Brassica rapa L.) in Uttarakhand region
