A field experiment was conducted during cropping seasons 2021-22 and 2022-23 at the Private Agricultural-cum-Research Farm, Beenda-Semaria Road, Rewa (M.P.) to study the utilization of nutrients by short-duration pigeonpea genotypes applied with phosphorus and sulphur. The N, P, K, S nutrient contents in grain and straw deviated significantly due to different genotypes and fertility levels as well as their interactions. The genotype TJT-501 as well as highest fertility level (P60 S45) recorded significantly higher N, P, K and S nutrient contents in grain and straw over the respective treatments. Consequently the uptake of these nutrients was found significantly higher in grain and straw of TJT-501 over other genotypes. Thus highest nutrients uptake by TJT-501, genotype producing a total biomass up to 54.64 q/ha, was 79.32 kg N, 12.84 kg P, 55.98 kg K and 11.93 kg S/ha. The uptake nutrients was found significantly higher in grain and straw due to increasing fertility levels up to P60 S45. Similarly the maximum N, P, K and S uptake was recorded under highest P60 S45 fertility level producing total biomass upto 70.64 q/ha. The findings suggest that due to heavy withdrawal of nutrients by pigeonpea genotypes, the succeeding crop must be nourished properly based on soil test values.
