Influence of Various Nutrient Sources on Rice (Oryza sativa L.) Productivity and Quality under Organic Farming

Abstract

The field investigation aimed to examine the impact of various organic nutrient sources on rice var. GNR-7 at the organic farm of ASPEE College of Horticulture, Navsari Agricultural University, Navsari, Gujarat during the kharif season of 2021. The experiment was structured using a Randomized Block Design with a factorial concept, incorporating two levels: soil application and foliar application. Total of twelve treatment i.e., S1: 100% RDN through NADEP compost, S2: 80% RDN through NADEP compost along with Azospirillium and PSB @ 2 l/ha each S3: 60% RDN through NADEP compost along with Azospirillium and PSB @ 2 l/ha each and S4: Ghan-jivamrut @ 500 kg/ha + Jivamrut @ 500 l/ha and that of foliar application were, F0: Control, F1: Novel organic liquid nutrient @ 1% and F2: moringa leaf extract @ 3%. The application of foliar spray was done thrice at 15, 30 and 45 days after sowing. were replicated thrice. The result revealed that S1 treatment significantly recorded the grain yield and S2 treatment significantly recorded the straw yield. While for foliar application, the treatment F2 significantly recorded the highest grain and straw yield but remained at par with F1 treatment. The mean data of quality parameters did not significantly change due to soil and foliar application of different organic nutrient sources. It can be determined that the soil application of 100 per cent RDN through NADEP compost and foliar application of either 3 per cent Moringa leaf extract or 1 per cent Novel organic liquid nutrient at 15, 30 and 45 DAS resulted in higher yield and also improved the quality parameters of rice under organic farm.
