Abstract
In a 2-year study, when 'Ganga 2' maize (Zea mays Linn.) was intercropped with 'Bragg' soybean [Glycine max (Linn.) Merr.] significantly decreased the leaf-area index of soybean by 9-51% at all stages, mean net assimilation rate by 24-66% 45-60 days after sowing. There was a significant reduction in dry matter (21-60%), branches (5-31%), pods/plant (23-54%) and grain yield (65-69%) of soybean. Maize did not affect 100-grain weight and seeds/pod. Reduction in the leaf-area index (3-55%) of maize was more at wider spacings and at 30-45 days after sowing. Except at harvest the dry matter of maize decreased by 6-15% with intercropping and the grain yield by 3-45% with intercropping.
