Abstract:

An experiment was conducted for three wet (kharif) seasons during 2008, 2009 and 2010 at the Agricultural College Farm, PJTSAU, Rajendranagar, Hyderabad to study the yield advantage and water productivity of supplemental irrigation to maize and red gram when grown as intercrops. There were three main treatments of irrigations - one supplemental irrigation each of 30 mm by drip at maize tasseling and red gram flowering, two supplemental irrigations of 30 mm of each by drip one each at maize tasseling and grain filling and red gram flowering and pod formation and Rain fed. These treatments were tested with combination four cropping systems - Sole Red gram, Sole Maize, Maize + Red gram intercropping (normal row) and Maize + Red gram intercropping (paired row) and replicated three times in strip plot design. The maize equivalent yield was significantly higher with two irrigations over that of one irrigation which in turn recorded significantly higher yield over rain fed. The water productivity was higher with two irrigations as compared to one and rain fed cropping. The water productivity was higher with Maize + Red gram normal planting followed by red gram sole crop, Maize + Red gram paired planting. The lowest water productivity was observed with maize sole cropping.
