Effect of Different Sources of Phosphorus on Protein Content, Soil Fertility and Yield of Greengram
Article | IMSEAR | ID: sea-229011
To study the effect of different sources of phosphorus on quality, fertility status and yield of greengram, an experiment was conducted during the kharif season of 2014 at Crop Research Farm, Department of Agronomy, SHIATS, Allahabad, UP. The experiment was conducted in randomized block design with 9 treatments viz. Control (No Phosphorus, 100% P through SSP, 100% P through URP, 50% P through SSP + 50% P through URP, 75% P through SSP + 25% P through URP, 100% P through SSP + PSB inoculation, 100% P through URP + PSB inoculation, 50% P through SSP + 50% P through URP + PSB inoculation, 75% P through SSP + 25% P through URP + PSB inoculation. Greengram variety Samrat was sown at a spacing of 30cm x 10 cm and it was fertilized with Phosphorus, SSP, URP, PSB as per the requirement of the treatments. The experimental results revealed that application of 100% P through SSP + PSB seed inoculation produced significantly higher grain yield (1496.77 kg ha-1), Stover yield (2920 kg ha-1) and protein (24.06%). There was a steady increase in the soil fertility status after harvesting of greengram. However, maximum available P2O5 (36.07 kg ha-1), available N (329.03 kg ha-1), available K2O (220.80 kg ha-1) was obtained with the application of 100% P through SSP + PSB seed inoculation. It also recorded higher net returns (Rs 47002.17 ha-1) and Benefit Cost (1.89). Thus, application of 100% P through SSP + PSB seed inoculation) helps in improving the quality and enhancing the yield in Greengram for resource poor farmers of India.
