Abstract
Field trials at Almora, Uttar Pradesh in the 1993-95 rainy seasons evaluated maize and soyabeans grown as pure stands or in different intercropping systems. All the intercropping patterns evaluated were superior in terms of maize-equivalent yield and LER values over sole crops. All the intercropping patterns except maize (60 cm) + soyabeans (45 cm) in a 2:1 row ratio, also recorded higher monetary returns compared to sole crops. Among different intercropping patterns of maize and soyabeans, paired rows of maize (30/90 cm) + 2 rows of soyabeans gave the highest total yield, maize equivalent yield and LER value, net return and benefit:cost ratio. Averaged over years, net return obtained under this intercropping pattern was 38.5%, 18.3%, 14.2% and 10.3% more compared to maize (60 cm) + soyabeans (45 cm) in 2:1 row ratio, one additional maize row after every two rows of sole soyabeans (45 cm), paired rows of maize (30/90 cm) + 1 row of soyabeans and paired maize rows (45/90 cm) + 2 rows of soyabeans, respectively.
