Abstract:
A field experiment was conducted during rabi season of 2022-23 at the Research Farm, A.K.S. University, Satna (M.P.) to study the effect of phosphorus levels on yield and uptake of nutrients in late-sown wheat. Amongst the application of increasing levels of inorganic phosphorus up to 90 or 100 kg/ha increased the yield-attributes, crop productivity, NPK nutrient contents in grain and straw as well as their total uptake per hectare by wheat var. JW-3336. The grain yield of wheat under 100 kg P₂O₅/ha was 35.53 q/ha, straw yield 53.72 q/ha and total N, P, K uptake was 127.75, 20.96 and 105.47 kg/ha, respectively. It may be inferred from the results that the application of inorganic phosphorus up to 90 kg/ha was found optimum in increasing the residual status of available N, P and K in soil besides crop yield and uptake of nutrients by the wheat crop.
