Abstract

A field experiment was conducted at Agricultural College and Research Institute, Madurai, during rabi 2010 - 2011 to study the effect of drip fertigation on growth, yield attributes and yield of cotton. In this study, growth parameters such as plant height, leaf area index (LAI), sympodial branches, dry mater production, root length, root dry weight were found to be enhanced by drip irrigation at 100 per cent Pan Evaporation (PE) along with 100 per cent drip fertigation (Recommended Dose of Fertilizer(RDF) as Water Soluble Fertilizer (WSF)). This combination of drip irrigation 100 per cent PE with drip fertigation 100 per cent RDF as WSF also increased yield attributes such as number of bolls plant -1 , boll weight and seed cotton yield.
