Long-Term Effect of Manures and Fertilizers on Nutrient Status under Cotton Mono-Cropping in Vertisol

Type: article
Abstract: The status of nutrients-their depletion and build up in soil and crop productivity after twenty two years (1991-2012) of cotton mono-cropping were studied under continuous use of various inorganic fertilizers and organic manure in a Vertisol. Results showed that application of 100% RD of NPK (90:45:45 kg ha-1) +FYM @ 10 t ha-1 recorded highest seed cotton yield of 2181 kg ha-1 which was on par with 150% RD of NPK treated plot. The soil pH and EC did not change significantly but markedly changed the organic carbon and available nutrient contents of the soil. Thus, the balanced use of fertilizers continuously either alone or in combination with organic manure is necessary for sustaining soil fertility and productivity of cotton under rainfed conditions.
