The present investigation in relation to "Effect of integrated plant nutrient system on phosphorus solubilisation and productivity of wheat in Vertisols" was conducted during rabi season of 2019-20 at Botany Research Farm, College of Agriculture, Nagpur. The results revealed that the use of ghanjivamrut @ 5 t ha -1 at incorporation of green manuring in combination with 50 % RD of chemical fertilizers + biofertilizers is the suitable nutrient source for maintaining soil available phosphorus nutrient at physiological growth stage and fertility status and it also improve the uptake of nutrient and yield of wheat. The grain yield of wheat was 3.63, 4.52 and 14.40 per cent higher over 100 % RDF + GM with the IPNS practice, there by 50 % chemical fertilizers can be saved and increase solubility.
