Effect of polythene mulch and irrigation levels on yield of Bt cotton

A trial was conducted to study the effects of Polythene Mulch and Irrigation levels on growth and yield of Bt cotton. at Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra (India) during kharif 2013-14 and 2014-15 on clayey soil. The experiment was laid out with eight treatment combinations in Factorial Randomized Block Design replicated thrice. Treatment comprises were without polythene mulch and with polythene mulch and four irrigation levels as 0.4 ETc, 0.6 ETc, 0.8 ETc and 1.0 ETc constituted the factor I and factor II respectively. The Polythene mulch treatment recorded significantly higher yield attributes, seed cotton yield (g) plant-1, Seed cotton yield (Kg ha -1,) Stalk yield (Kg ha -1,) over without polythene mulch both being at par with each other, recorded significantly higher number of bolls plant-1 than 0.4 ETc (33.42). But Interaction effect between mulch and irrigation was found to be non-significant.
