Influence of Conventional and Non-conventional Organic Sources of Plant Nutrients and Industrial Refuse for Yield and Quality Enhancement of Radish

Abstract

Background: India generates about 50 million tons of municipal solid wastes (MSW) every year. Composting MSW is viewed as a low-cost method of diverting organic wastes from landfills in to a valuable product of agricultural importance. Farm Yard Manure (FYM) is an organic matter rich with a small quantity of nitrogen, while rice hull ash is a good source of plant nutrients particularly of potash. Bagasse ash is a waste obtained from sugar industries and is capable of supplying significant amount of plant nutrients.The present investigation aimed to study the effect of organic sources of plant nutrients and industrial waste on yield and quality of radish as a supplementary source of plant nutrients.Methods: A pot trial investigation was carried out during 2019 at Annamalai University, Chidambaram, Tami Nadu to study the influence of conventional and non-conventional organic sources of plant nutrients and industrial refuse on yield and quality of radish. Under this trial, FYM (12.5 t ha-1), Municipal Solid Waste Compost (25 t ha-1), Rice hull ash (5 t ha-1), Bagasse ash (10 t ha-1) with 100% RDF and 75% RDF were tried.Result: The present investigation under pot trial showed that the maximum radish root yield, shoot yield and quality were observed due to the application of organic sources of plant nutrients of both conventional and non-conventional organic sources and industrial refuse.
