An experiment was carried out in the Department of Horticulture, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U.P.), India, during 2015-16 and 2016-17 to study the influence of integrated nutrient management on vegetative growth, fruiting, yield and soil physical characters in papaya (Carica papaya L.). For this plant of Sapna cultivar was planted on 20th March during both years of experimentation at a spacing of 2.0 x 2.0 m. There were eighteen treatments comprising Azotobacter, PSB and vermicompost with graded dose of RDF including one control, replicated thrice in randomized block design. All treatments were applied at the time of planting in the field. The data of both the years of experiment were analyzed which clearly shows that maximum plant spread from North to South direction and from East to West direction, maximum number of leaves and font area, biomass per plant, number of flowers, number of fruits set and yield per plant with minimum fruiting height and fruit developmental period were recorded with the application of RDF 75% + Azotobacter 100 g + PSB 100 g + vermicompost 2 kg/plant, which was significantly higher than the control, whereas the minimum plant spread from North to South direction and from East to West direction, minimum number of leaves and font area, biomass per plant, number of flowers, number of fruits set and yield per plant with maximum fruiting height and fruit developmental period were recorded under unfertilized plants during both years of experimentation. As various soil physical characters are concerned maximum available potassium, organic carbon per cent, available nitrogen, available phosphorus with minimum soil pH and soil electrical conductivity were recorded in the field fertilized with RDF 75%+ Azotobacter 100 g + PSB 100 g + vermicompost 2 kg/plant, whereas the minimum available potassium, available nitrogen, available phosphorus, minimum organic carbon per cent with maximum soil pH and electrical conductivity were recorded in field kept under control, where non amount of fertilizers were applied during both years of present investigation.
