Abstract
A field experiment was conducted in the Organic farm, Department of Natural Resource Management, ASPEE College of Horticulture, Navsari Agricultural University, Navsari, Gujarat in the year 2021 in summer season. The experiment was laid out in Randomized Block Design with Factorial concept (FRBD) comprising of two factors each having three levels i. e. soil application viz., S1 (100 % RDN through NADEP compost), S2 (Ghan-jivamrut @ 500 kg/ha) and S3 (Ghan-jivamrut @ 500 kg/ha + Jivamrut @ 500 l/ha) and foliar application viz., F0 (Control), F1 (Novel organic liquid nutrient @ 1 %) and F2 (Moringa leaf extract@ 3 %) was given thrice at 15, 30 and 45 DAS. The result revealed that S1 treatment significantly recorded the seed yield. While for foliar application, the treatment F2significantly recorded the highest seed yield and stover yield but remained at par with F1 treatment. 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 soil properties as compared to the initial status of soil after harvest of black gram under organic farm.
