Abstract: 

IN ORDER TO STUDY THE EFFICIENCY OF FOUR HERBICIDES INCLUDING PENDIMETHALINE, OXYFLOURFEN, TRIFLURALIN, IMAZETHAPYR, AND HAND WEEDING ON WEEDS AND CROP YIELD OF CHICKPEA, AN EXPERIMENT WAS CONDUCTED AT THE RESEARCH FARM OF FERDOWSI UNIVERSITY OF MASHHAD, IRAN DURING THE GROWING SEASON OF 2007 - 2008. THE EXPERIMENTAL DESIGN WAS RANDOMAZED COMPLETE BLOCK WITH THREE REPLICATIONS. WEED CONTROL TREATMENTS INCLUDED THE PRE- PLANT APPLICATIONS OF TRIFLURALIN (3LIT/ HA); PENDIMETHALINE (3LIT/ HA); IMAZETHAPYR (1.5LIT/ HA); PENDIMETHALINE (2LIT/ HA) +ONE HAND WEEDING; PREEMERGENCE APPLICATIONS OF OXYFLOURFEN (1.5LIT/ HA); PENDIMETHALINE (2LIT/ HA) +OXYFLOURFEN (1/ 5LIT/ HA); IMAZETHAPYR (1LIT/ HA); POST- EMERGENCE APPLICATIONS OF OXYFLOURFEN (2LIT/ HA); ONE HAND WEEDING; TWO HAND WEEDING AND FINALLY A WEED FREE AND WEED INFESTED PLOT ALSO WERE COSSIDERED AS CHECKS. THE RESULTS SHOWED THAT CHICKPEA SEED AND DRY WEIGHT WEEDS WERE SIGNIFICANTLY AFFECTED BY WEED CONTROL TREATMENTS (P<0.05). IN THE SURVEY, THE MOST DECREASE IN DRY WIEHGT OF WEEDS RELATED ON PRE- PLANT APPLICATIONS OF PENDIMETHALINE, PRE- EMERGENCE APPLICATIONS OF OXYFLOURFEN, PENDIMETHALINE+ONE HAND WEEDING, PRE- PLANT APPLICATIONS OF TRIFLURALIN AND PRE- EMERGENCE APPLICATIONS OF IMAZETHAPYR WITH PERCENT OF 84.64, 83.72, 82.84, 78.03 AND 75.82. THE RESULTS SHOWED THAT MAXIMUM GRAIN YIELD WAS OBTAINED IN TREATMENT INCLUDING PRE- PLANT APPLICATIONS OF PENDIMETHALINE (2LIT/ HA) +ONE HAND WEEDING WITH YIELD OF 1122 KG/HA. SO PRE- PLANT APPLICATIONS OF IMAZETHAPYR (1.5LIT/ HA), PENDIMETHALINE (3LIT/ HA), AND TWO HAND WEEDING WITH YIELD OF 980, 952, 943KG/HA WERE THE BEST TREATMENTS. THIS STUDY EXHIBITED THE INTEGRATED TREATMENTS OF PRE- PLANT APPLICATIONS OF HERBICIDE AND ONE PROCESS HAND WEEDING HAVE MAXIMUM YIELD OF CHICKPEA.
