Effect of water-soluble fertilizers through fertigation on quality, nutrient content and nutrient uptake of Bt cotton

Abstract

Field experiment was conducted at research farm, Department of Soil Science and Agricultural Chemistry, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during kharif season of 2013-14 to study the effect of water soluble fertilizers through fertigation on quality, nutrient content and uptake of Bt cotton. The quality parameters like lint index, ginning percentage and test weight of cotton significantly improved with application of 100 per cent RDF through soluble fertilizers by fertigation over 100 per cent RDF through conventional fertilizers. Application of 100 per cent RDF through soluble fertilizers by fertigation significantly increased nitrogen, phosphorus and potassium content and their uptake in stalk of cotton over the application of RDF through conventional fertilizers.
