Abstract:
A trial was conducted to study the effects of Polythene Mulch and Irrigation levels on growth, yield, water use efficiency and economics 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 of 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 the factor II respectively. Application of polythene mulch recorded significantly higher seed cotton yields Water use efficiency, highest gross monetary returns, net monetary returns and B:C ratio over without polythene mulch. The seed cotton yield ha-1 was significantly higher with irrigation level 0.8 ETc over other irrigation levels. However, water use efficiency was higher under irrigation level 0.4 ETc, followed by 0.6 ETc, 0.8 ETc, and lowest under the1.0 ETc. Significantly highest gross monetary returns, net monetary returns and B:C ratio were obtained with the irrigation level 0.8 ETc.
