Abstract :
A field experiment was carried out to study the relationship between manual weeds removal timings and garlic production during winter 2007-08 at Government Seed Farm, Rakh Manghan, Dera Ismail Khan Pakistan. Randomized complete block design, having five replications, was used in the experiment. The treatments were; No weeding (weedy check), Two weedings (75 days interval), Three weedings (60 days interval), Four weedings (45 days interval), Six weedings (30 days interval), and Twelve weedings (15 days interval). Garlic yield (t ha-1) and yield components (bulb diameter, height and weight) increased significantly (P≤0.001) with increase in manual weeds removal timings, whereas, weeds density, fresh and dry weeds biomass decreased significantly (P≤0.001) with increase in manual weeds removal timings. Negative linear relationship between bulb yield and weeds fresh and dry biomass (t ha-1) and positive linear relationship between bulb fresh weight and bulb diameter were observed.
