The choice of variety, sowing time and optimum nutrition are important management options to optimise the seed yield. Accordingly, an experiment comprising of 18 treatments was conducted during the winter 2017-2018 and 2018-2019 in a factorial randomized block design, replicated three times to assess the response of pea genotypes (DPP-SP-6, Him Palam Matar-1 and Pb-89) to the seeding time (26th October and 10th November) and nutrient levels (0, 100 and 125% of the recommended NPK). The individual treatment effects revealed that early sowing, application of 125% NPK and DPP-SP-6 were significantly superior for the seed yield and related traits. The interaction effects indicated a significant response of the 125% NPK on the early sown crop for the seed yield, harvest index and NPK uptake. Significantly highest soil available NPK were obtained at 125% NPK with a respective increase of 41.54, 5.90 and 30.82 kg/ha, respectively, over the initial status. Early sowing of DPP-SP-6 with an application of 125% NPK is a better preposition for enhancing the productivity of peas.
