RESPONSE OF INTERCROPPING SYSTEM INVOLVING MAIZE (ZEA-MAYS) TO IRRIGATION LEVEL IN KASHMIR VALLEY

An experiment was conducted during summer season of 1991 and 1992 to f ind out the response of maize (Zea mays L.) legume intercropped system s to different irrigation levels under temperate condition of Kashmir. Irrigation level of IW (irrigation water 65 mm); CPE (cummulative pan evaporation 86 mm) 0.75 gave the maximum optimum maize yield and maiz e-equivalent yield, which was at par with IW:CPE 1.0. The water expens e with optimum IW:CPE 0.75 regime was 30.4 cm and water-expense effici ency the maximum (126 kg/ha-cm). Maize + cowpea [Vigna unguiculata (L. ) Walp.] and maize + greengram (Phaseolus radiatus L.) recorded signif icantly highest maize-grain yield but maize + field bean (Phaseolus vu lgaris L.) gave the highest maize-equivalent yield.
