Abstract:

A field experiment was carried out during the rainy ( Kharif ) season of 2009-10 at Rajendranagar, Hyderabad, to find out production potential and economic feasibility of rainfed maize ( Zea mays L. ) intercropping with soybean ( Glycine max L.) under row proportion of 1:1 and 1:2 at varying doses of zinc through zinc sulphate (0, 25, 50 and 75 kg ha -1 ). The result revealed that growth and yield components of maize and soybean were less in intercropping systems compared to sole cropping. Intercropping of 1:1 and 1:2 ratios declined the seed yield by 14.75 and 11% in maize and 52.19% and 38.34% in soybean as compared to sole crop. However, the total productivity of systems in terms of maize grain equivalent and LER (6182 kg ha -1 and 1.47) was found to be higher with maize + soybean 1:2 ratio. Irrespective of the cropping system, application of 50 kg ZnSO 4 ha-1 recorded significantly higher grain yield of maize and soybean (5301 and 936 kg ha -1 ), maize-equivalent yield (6850 kg ha -1 ) and LER. Highest net return (Rs. 43594) and B:C ratio (2.26) were found in maize + soybean 1:2 ratio with 50 kg ZnSO 4 ha -1 application.
