Research on Crops

Field experiments were conducted during bharif and rabi seasons of 2008-09 at GKVK, University of Agricultural Sciences, Bangalore, Karnataka to study the effect of intercrops and paired rows on growth and yield of maize (Zea mays L.). Under rainfed condition, maize intercrop with gardenpea (Pisum sativa L.) followed by frenchbean (Phaseolus vulgaris L.) areas was found better than fieldbean and soybean. Whereas the row ratio 2: 3 followed by 2: 2 proved better than 1: 1 with respect to productivity of maize. Among various intercropping systems, maize+gardenpea at 1: 1 row ratio significantly achieved higher in growth parameters viz., plant height, number of leaves and total dry matter production and yield and yield components viz., number of grains per cob, test weight, cob length, cob girth, maize grain yield and maize equivalent yield in maize+gardenpea at 2: 3 in paired rows over the other inter cropping system. Intercropping gardenpea proved compatible, remunerative higher price and less competitive with maize at 2: 3 ratios rather than 1: 1 and 1: 2 row ratios. Source
