A STUDY ON THE PLANT NUTRIENT SYSTEM ON THE SOLUBILISATION OF THE PHOSPHORUS

Abstract

During the 2019-20 rabies season at Botany Research Farm, College of Agriculture, Nagpur, the current investigation into the 'Impact of the Integrated Plant Nutrient System on Phosphorus Solubilization and Productivity of Wheat in Vertisols' was conducted. The results revealed that the use of ghanjivamrut @ 5 t ha-1 in combination with 50 percent RD of chemical fertilizers + bio-fertilizers for the incorporation of green manure is the appropriate nutrient source for maintaining the phosphorus nutrient available to the soil at the physiological growth stage and fertility status and also improves nutrient uptake and wheat yield. With the IPNS practice, the grain yield of wheat was 3.63, 4.52 and 14.40 percent higher than 100 percent RDF + GM, where 50 percent chemical fertilizers can be saved and solubility increased.
