Effect of different organic manures and inorganic fertilizers on chemical properties of cucumber (Cucumis sativus L.) in lateritic soils of Konkan

Abstract

The field experiment was conducted to assess the “Effect of different organic manures and inorganic fertilizers on chemical properties of cucumber (Cucumis sativus L.) in lateritic soils of Konkan” at the Department of Horticulture, at the College of Agriculture, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, during kharif season in the year 2015-16. The experiment was laid out in Randomized Block Design (RBD) with three replications. The present study was formulated to reduce the inorganic fertilizer dose by using various organic manures and there combinations. The experiment comprised thirteen treatments with the combined application of chemical fertilizers, FYM, poultry manure and vermicompost in cucumber resulted increased the all chemical properties. The application of 50% RDF through inorganic plus 50% RDN through poultry manure had shown its influence on the soil pH, electrical conductivity and organic carbon as well as available nutrient status of Nitrogen (477.70, 337.67, 254.01 kg ha-1) at 30 DAS, 60 DAS and at harvest, Phosphorus (19.27, 15.80, 12.43 kg ha-1) at 30 DAS, 60 DAS and at harvest and Potassium (582.40, 417.54, 362.43 kg ha-1) at 30 DAS, 60 DAS and at harvest respectively. In general, it was concluded that the application of 50% RDF through inorganic plus 50% RDN through poultry manure was found to be suitable for improving chemical properties of lateritic soils of Konkan.
