Abstract

A study was conducted to determine the CRITICAL PERIOD of weed control in sugar beet (Beta vulgaris L.) during 1997 in Shahrood District. Treatments included weed free and weed infested periods up to 14, 28, 42, 56, 70, 84 days after emergence and to the end of growth season (Weed free and Weed interference, respectively). Treatments were replicated four times in a complete randomize block design.Results showed a CRITICAL PERIOD of 10 to 108 days after emergence for weed control (with 5% allowance for yield reduction), for root yield and 11 to 128 days after emergence for sugar yield. Weed free period up to 14 and 42 days after emergence reduced weeds dry weight by 47% and 80% compared to weedy check respectively.Weed infested up to the end of growth season reduced root yield by 91.5% and sugar yield by 94.5% compared to weed free check.
