Abstract
An experiment on integrated nutrient management in guava grown as a component crop in a coconut-based cropping system was conducted under the coastal condition of Odisha. Adoption of integrated nutrient management like the application of organic manures with or without NPK fertilizers resulted in improvement in the physico-chemical properties of soil, which was reflected in terms of pH, organic carbon content, available nitrogen, phosphorus and potash content. Among the different combination of integrated nutrient management applied in guava, the plant height, canopy spread, flushing intensity, yield and yield attributing parameters. The maximum available soil nitrogen, available phosphorus and available potassium contents were estimated to be maximum in the treatment applied with 50% RDF +50% N through vermicompost + FYM +bio fertilizer, while the soil pH was highest owing to application of 75% RDF + 25% N through vermicompost + FYM which was at par with results obtained with application of 75% RDF + 25% N through vermicompost and 75% RDF +25% N through vermicompost + FYM +bio fertilizer.
