Abstract: 

IN ORDER TO EVALUATE EFFECT OF ADDITIVE INTERCROPPING GRAIN SORGHUM AND COWPEA ON WEED CONTROL IN LIMITED IRRIGATION CONDITION AN EXPERIMENT WAS CONDUCTED IN THE RESEARCH FARM OF COLLEGE OF AGRICULTURE, TEHRAN UNIVERSITY IN SPRING 2006. THE EXPERIMENTAL TREATMENTS WERE ARRANGED IN SPLIT PLOTS BASED ON A COMPLETE RANDOMIZED BLOCK DESIGN WITH FOUR REPLICATIONS. THE LIMITED IRRIGATION (MOISTURE STRESS) TREATMENT OF IR1: NORMAL WEEKLY IRRIGATION (CONTROL), IR2: MODERATE MOISTURE STRESS DURING VEGETATIVE AND GENERATIVE GROWTH, IR3: MODERATE MOISTURE STRESS DURING VEGETATIVE AND SEVERE DURING GENERATIVE GROWTH, IR4: SEVERE MOISTURE STRESS DURING VEGETATIVE AND MODERATE DURING GENERATIVE GROWTH WERE ALLOCATED TO THE MAINPLOT AND DIFFERENT COMBINATION OF SORGHUM AND COWPEA ADDITIVE INTERCROPPING SYSTEM OF S1: SOLE SORGHUM (WITH WEEDING), S2, S3 AND S4 AN ADDITIVE SERIES 15, 30 AND 45% OF THE SOLE SEED RATE OF COWPEA MIXED WITH FULL SORGHUM SEED RATE AND S4: SOLE SORGHUM (WITHOUT WEEDING) WERE ALLOCATED TO SUB PLOTS. THE RESULTS OF THIS EXPERIMENT SHOWED THAT WEED DENSITY WAS SIGNIFICANTLY LESS IN SORGHUM-COWPEA INTERCROPPING TREATMENTS COMPARE TO SOLE SORGHUM (S5) AND S4 TREATMENT WHICH HAS THE LOWEST NUMBER OF WEEDS IN CONTRAST WITH OTHER TREATMENTS. THESE FINDING SUGGEST THAT ADDITIVE INTERCROPPING SORGHUM-COWPEA SUPPRESSES WEEDS AND IT IS AN EFFECTIVE WAY TO BIOLOGICAL WEED CONTROL.
