The integrative use of residue mulch and phosphorous benefits the crop growth and yield through increased availability of nutrients, in turn improve nutrient uptake leads to increase in growth and yield. The experiment was conducted to study the residual effect organic mulching and residual phosphorous of preceding crop on summer sweetcorn crop. The experiment was conducted in split-plot design with three residual organic mulch levels (un mulch (UM), rice straw mulch (RSM, maize stover mulch (MSM)) and four residual rates of P (0, 40, 80, 120 kg ha-1) on growth, nutrient uptake and yield of sweetcorn. At the time of harvest of sweet corn RSM and MSM has reported 13.68 and 9.62% higher plant height, 20.35 and 8.89% higher dry matter content, 34.79 and 24.21% higher CGR, 12.31 14.54% higher RGR, 11.74 and 6.99% higher LAI and 21.68 and 18.87% higher NAR has been reported respectively over UM. Among the rate of P, P120 has reported 13.74% higher plant height, 14.87% higher dry matter accumulation, 28.16% higher CGR, 8.30% higher RGR, 7.54% higher LAI, 15.22% higher NAR has been reported over P0 treatment. Overall mulching along with increased rate of P has improved growth, nutrient uptake and yield of sweetcorn crop.
