A field experiment was conducted during kharif seasons of 2003 and 2004 at the research farm. Regional Agricultural Research Station, Guntur to find out the response of cotton to irrigation at critical growth stages in vertisols of coastal Andhra Pradesh. The plots receiving irrigation at boll development stage recorded marked increase in seed cotton yield. The treatment receiving irrigations at IW/CPE ratio resulted in lower water use efficiency, net returns and benefit:cost ratios though it yielded comparable seed cotton yield with the treatment receiving irrigation at boll development stage and markedly higher yield than the control plots.
