Impact analysis of demonstration on integrated nutrient management in Green gram

Abstract

Green gram (Vigna radiata) is an important and traditional pulse crop of Odisha. Green gram is the major source of protein and fibre. It is eaten both in raw form (sprouted green gram) and cooked form (dal).It can be grown in all the seasons i.e during kharif, pre-rabi, rabi and summer season in Bargarh district of Odisha. A Demonsration was undertaken during Rabi 2015-16 &2016-17 in the farmer’s field of Bargarh District of Odisha to find out the response of integrated nutrient management on plant growth, yield in green gram cv.TARM-1. In this Demonsration, INM includes Soil application of Zn (25kg zinc sulphate/ha) and B (10 kg borax/ha), seed treatment of Rhizobium and PSB (200g/10kg of seed) with recommended dose of NPK. Applications of 25kg ZnSO4/ha, 10 kg borax/ha and seed treatment with Rhizobium (200g/10kg of seed) and PSB (200g/10kg of seed) resulted in enhancement of plant growth and yield characteristics.23% & 20% increase in yield was obtained with application of integrated nutrient management in farmer’s field during 2015-16 and 2016-17 respectively.
