Abstract: 

TWO FIELD EXPERIMENTS WERE CARRIED OUT IN ORDER TO EVALUATE THE EFFECTS OF PLANTING DATE, METHOD AND DATE OF WEED CONTROL ON YIELD AND YIELD COMPONENTS OF CUMIN IN THE EXPERIMENTAL RESEARCH FIELD, FACULTY OF AGRICULTURE, DURING 2006 AND 2007. TREATMENTS INCLUDED PLANTING DATE (30 DECEMBER, 20 JANUARY AND 30 FEBRUARY), WEEDING DATE (FIRST TRUE LEAF, START OF BRANCHING AND BEGINNING OF FLOWERING STAGES) AND WEED CONTROL METHODS (HAND WEEDING, FIRE TREATMENT AND CONTROL). THE RESULTS SHOWED THAT THERE WERE SIGNIFICANT DIFFERENCES BETWEEN DIFFERENT SOWING DATE, AS THE HIGHEST YIELD WAS IN 30 DECEMBER AND THE LOWEST WAS IN 30 FEBRUARY. HOWEVER, DELAYING OF SOWING DATE DECREASED NUMBER OF SEED AND BIOLOGICAL YIELD. THERE WERE ALSO SIGNIFICANT DIFFERENCES IN START OF BRANCHING STAGE, BRANCHING STAGE AND FIRST TRUE LEAF STAGE IN DIFFERENT TIMES OF WEED CONTROL AS THE HIGHEST YIELD WAS CONSIDERED IN THE START OF BRANCHING. IT SHOWED THAT THERE WERE SIGNIFICANT DIFFERENCES BETWEEN HAND WEEDING, CONTROL AND FIRE TREATMENTS. THE HIGHEST YIELD OF SEED AND BIOLOGIC WAS OBTAINED IN HAND WEEDING METHODS.
