Abstract
Background: Rice fallow pulse cropping system was familiarized in Tamil Nadu. There is reduction in yield due to inappropriate management of pest, disease, weed, fertilizer and nutrient management moreover cultivated as rainfed/ mixed cropping system. However, succeeding crop is sown without any preparatory cultivation in the stubbles of the previous crop. It minimizes the labour and fuel cost. The present study investigated the economic analysis of drip fertigation, Organic product for rice-fallow-greengram. Methods: A field experiment was conducted at Wetland farms of Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore during 2019-21. There are thirteen treatments in randomized block design with replicated thrice which is imposed with fermented fish waste and fermented egg product applied through drip at vegetative stage and peak flowering stage. Result: The field experiment result revealed that the application drip fertigation @ 125% RDF, 100% PE with FFW (2 times) (T11) recorded higher net return (₹ 48,958 and ₹ 33,402 during summer 2020 and Kharif 2021, respectively).
