ABSTRACT

The field experiments were conducted in Agronomy Department Farm, College of Agriculture, Dapoli. Dist. Ratnagiri during Kharif seasons to study the “Nutrient status of soil after the harvest of pigeonpea as influenced by Intigrated nutrient Management”. Results showed that available N and P content of soil after harvest of pigeonpea were improved due to all the nutrient management treatments over their respective initial values. Application of 75 % RDF + Two foliar sprays of nutrients (Potassium nitrate 1% + DAP 1% + Boron 500 ppm at flowering and 20 days after first spray) + Biofertilizers (Rhizobium +PSB) and RDF + Biofertilizers (Rhizobium + PSB) remained at par and both the treatments significantly improved the available N and P status of soil after harvest of pigeonpea crop over rest of the nutrient management treatments. the values were rather higher compared to their initial levels indicating the increased production of pigeonpea without reduction in soil fertility.

Key words : Cajanus cajan, Harvest, Nutrient status, Soil.
