Effect of planting pattern of intercropped legumes (Soybean, groundnut and mungbean) on yield and nutrient uptake of legumes from the intercropping system at mid altitude of Meghalaya

A field experiment was conducted in mid-altitudes of Meghalaya during the kharif season of 2015 to study the effect of intercropped legumes and their planting pattern on the yield and nutrient uptake of legumes. The experiment was conducted in randomized block design with ten treatments replicated thrice. Three legumes namely mungbean, soybean and groundnut were intercropped with maize in additional series as 1:1 intercropping and two rows of intercrop legumes in between paired rows of maize included in the study. All the growth and yield parameters of intercrops (soybean, mungbean and groundnut) were considerably affected when intercropped with maize except for harvest index. In all three legumes, their sole planting recorded considerably higher uptake of total N, P, K over their intercropping treatments. Total uptake N and K was recorded considerably higher from sole soybean while total uptake of P was recorded considerably higher from sole groundnut.
