ABSTRACT
The efficiency of maize + mungbean intercropping method for yield and yield attributes were studied under different crop combination at the Research Farm of The University of Agriculture Peshawar, Pakistan during the year 2012. The study was carried out in a split-plot design with three replications. Herbicide treatments (herbicide used and herbicide not used) were assigned to main plots, while intercropping treatments (sole maize, sole mungbean, 5 rows of mungbean + 6 rows of maize, 10 row of mungbean + 6 rows of maize) were allotted to subplots. Results of the study revealed that weed density m-2, fresh weed biomass in maize and mungbean crops were significantly affected by both the main-plot and sub-plot treatments. Similarly, number of seeds pod-1, thousand grains weight, grain and biological yield of mungbean were also found significant. In main plots, weed density m-2 (16.47) and fresh weed biomass (529.8) were lower in herbicide treated plots in mungbean crop. Number of seeds pod-1 (10.85), thousand grains weight (30.15g), grain yield (366.56 kg ha-1) and biological yield of mungbean (1306.7 kg ha -1) were higher in herbicide treated plots. Subplots sown with sole mungbean resulted in heavier 1000 grains weight (32.95g), higher number of seeds pod-1 (11), grain yield (427 kg ha-1) and biological yield (1522 kg ha-1). The intercropping treatments of 10 rows mungbean + 6 rows maize resulted in lighter 1000 grains weight (30.1g) and seeds pod-1 (10). Grain yield (269 kg ha-1) and biological yield (1023 kg ha-1) of mungbean were significantly lower in 5 rows mungbean + 6 row maize intercropping treatments. It is concluded from our results that sowing of mungbean as sole was the most effective in terms of mungbean grain and biological yields. Mungbean can also serve as a compatible component in intercropping system involving maize crop, based on our results.
