EFFECT OF DIFFERENT APPLICATION METHODS OF VARIOUS ORGANIC MANURES ON PLANT POPULATION AND GROWTH ATTRIBUTES OF RABI SWEETCORN

A field experiment was conducted during rabi, 2023-24 to study the response of rabi sweet corn (Zea mays.Saccharata) to methods and application of various organic manures under integrated nitrogen management system in alfisols of southern Telangana zone.The experiment was laid out in a randomized block design with eleven treatments and three replications.The treatments consisted of integration of chemical fertilizer and various organic manures viz., poultry manure (PM), farm yard manure (FYM), vermicompost (VC), sheep manure (SM) and jeevamruta.The results showed that 75% Recommended dose of nitrogen (RDN) through chemical fertilizer + 25% RDN using poultry manure (PM) through band application achieved the tallest plants (188.4 cm), the highest leaf area index of 5.8 and this led to the highest drymatter production with 13045 kg ha -1 .This was comparable with 75% RDN + 25% RDN using farm yard manure (FYM) through band application and 100% Recommended dose of nitrogen.Band application of organic manures showed higher results than their broadcasting, which suggests that under integrated nitrogen management system, band application of organic manures on the day of sowing could be introduced in nutrient management for better growth of sweetcorn in alfisols of semi-arid region.
