Response of Nutrient Management Practices through Organic Substances on Rice var. GR-11 in North Konkan Coastal zone of Maharashtra

Abstract

The management of soil organic matter is crucial to maintain a productive organic farming system. No one source of nutrient usually fulfills to maintain productivity and quality control in organic system. In addition, the inputs to supplement nutrient availability are often not uniform presenting additional challenges in meeting the nutrient requirements of crops in organic system. With this concept, a field experiment was conducted at the research farm of ASPEE Agricultural Research and Development Foundation, Tansa Farm, at Nare, Taluka Wada, Dist. Palghar, Maharashtra, during Kharif 2018-19 in rice. Different treatments comprising organic amendments such as T1-FYM @ 5 t/ha (control), T2-T1 + vermicompost @2.5 t/ha, T3-T1+Neem cake @ 250 kg, T4- T1+ vermiwash @ 3% spray, T5-T1+ Jeevamrut @ 3 % spray, T6-T1+ Panchgavya @ 3 % Spray, T7-T1+ Enriched Bananpseudostem sap @ 3% spray and T8-T1+ Regular Banana sap @ 3% spray were tried in organic crop production. These treatments were compared with absolute control (FYM @ 5 t/ha + No biofertilizer+ No Spray). A Rice variety ‘GR-11’ was taken for study. Results revealed a significant enhancement in grain yield of rice over absolute control due to the application of different organic amendments applied alone or in combinations. The rice grain yield (3.19 t ha-1) obtained under combined application of FYM and vermicompost was at par with the yield recorded under neem cake, vermiwash and panchgavya. An interesting observation recorded was that there was no serious attack of any insects pest or disease in organically grown crop. The study revealed that addition of four organic amendments viz. vermicompost, vermiwash, neem cake&panchgavyacould give the optimum yield of organic rice var. GR-11.
