Effect of Water-Soluble fertilizers through fertigation on growth, yield component and yield of Bt cotton

Abstract

Field experiment was conducted during kharif season of 2013-14 to study the effect of water soluble fertilizers through fertigation on growth, yield component and yield of Bt cotton at research farm, Department of Soil Science and Agricultural Chemistry, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. The experiment was carried out in randomized block design with five treatments and four replications. The treatment consists of T1- Recommended dose of fertilizers through soil application, T2- Recommended dose of fertilizers through fertigation (conventional), T3-100% RDF through soluble fertilizers by fertigation, T4- 80% RDF through soluble fertilizers by fertigation and T5- 60% RDF through soluble fertilizers by fertigation. The growth and yield component like plant height, number of leaves, leaf area, number of bolls, seed and stalk yield of cotton significantly improved with application of 100 per cent RDF through soluble fertilizers by fertigation into six splits followed by 80 per cent RDF through soluble fertilizers.
