Abstract: 

IN ORDER TO EVALUATING THE EFFECT OF CORN/SOYBEAN INTERCROPPING ON GRAIN YIELD AND WEED CONTROL, AN EXPERIMENT WAS CONDUCTED IN A SPLIT PLOT ARRANGEMENT IN RANDOMIZED COMPLETEBLOCK DESIGN WITH FOUR REPLICATIONS AT THE FIELD STATION OF AGRICULTURAL SCIENCES AND NATURAL RESOURCES, UNIVERSITY OF SARI, DURING 2008-2009 CROPPING SEASON. IN THIS EXPERIMENT MAIZE (SC704) AND SOYBEAN (032) WERE INTERCROPPED. IN THIS STUDY, THE MAIN PLOTS WERE DIFFERENT DATES OF PLANTING (APRIL 20, MAY 4 AND MAY 19). SUB PLOTS WERE PURE STAND OF TWO CROPS AS WELL AS THREE INTERCROPPING RATIOS (2 SOYBEAN+ 2 CORN ROWS, 3 CORN+2 SOYBEAN+3 CORN ROWS, 3 SOYBEAN +2 CORN+3 SOYBEAN ROWS). RESULTS SHOWED THAT INTERCROPPING OF MAIZE AND SOYBEAN CONTROLLED WEEDS AND INTERCROPPING RATIO OF 2CORN+3 SOYBEAN+2CORN ROW PLANTING HAD THE LOWEST WEEDS DENSITY AND BIOMASS. INTERCROPPING OF 2 CORN+3 SOYBEAN+2CORN ROW PLANTING ON MAY 19 WAS THE SUPERIOR TREATMENT, BECAUSE OF THE HIGHEST LAND EQUIVALENT RATIO (1.37) AND THE HIGHEST GRAIN YIELD. THIS WAS REFERRED TO BETTER USE OF GROWTH INPUTS AND CONTROL OF WEEDS BIOMASS AND DENSITY AS COMPARED TO MONOCULTURE. GENERALLY, INTERCROPPING OF 2 CORN+3 SOYBEAN+2CORN ROW PLANTING ON MAY 19 WAS OF HIGH GRAIN YIELD, BETTER USE OF GROWTH RESOURCE AND REDUCING OF WEEDS DENSITY.
