Manukonda S, Anusha B and Satyanarayana PV

Field experiments were conducted during 2014 and 2015 Kharif season in deltaic alluvial soils at APRRI & RARS, Maruteru, Andhra Pradesh to develop suitable organic farming package for rice based cropping systems for enhancing productivity. Treatments mainly comprise of combination of organic and inorganic fertilizers. Significantly higher tiller count, panicle count and grain yields were realized with 100% NPK+micronutrients through inorganic followed by 50% NPK through inorganic and 50% N through FYM. Among organic sources, 100% N through organic sources+organic practices for weed and pest control recorded highest grain yield followed by 100% N through organic sources+Bio-fertilizers in both the years. This clearly indicates conjunctive use of organic and inorganic fertilizers improves grain yield besides soil health.
