A plot experiment was supervised in open pollinated field to evaluate the response of lower doses of Nitrogen combined with standard to high potassium and Phosphorus doses and the relative effects on sweet sorghum (Sorghum bicolor L. Moench) yield in Panskura Agriculture Field located at East Midnapore of West Bengal during 2017-18 in a randomized block design (RBD) with three replications. Data were collected on every 30 days interval starting from 40 Days After Sowing (DAS) to 130 DAS. Results revealed that maximum plant height of 193.4 cm was observed in N3P2K2 treatment at 130 DAS, maximum green biomass of 26.84 t/ha was observed with N3P2K3 treatment at 100 DAS, maximum sugar concentration of 10.07 % was observed with N3P2K2 treatment at 100 DAS and highest sugar yield of 1896.88 kg/ha with the same ratio of fertilizer treatment. All the parameters were evaluated to identify the cost-effective status as well as the significance of the study.
