Abstract

In order to determine the response of YIELD AND YIELD COMPONENTS of POTATO in seed production and commercial planting densities to WEED INFESTATION periods an experiment was conducted in Agricultural Research Farm of Bu-Ali Sina University in 2006. This experiment was conducted in a factorial arrangement based on a randomized complete block design with three replications.Experimental treatments were POTATO PLANT DENSITY at two levels, 5.33 (optimum PLANT DENSITY of commercial fields) and 6.66 (optimum PLANT DENSITY of seed production fields) plant per square meter and WEED INFESTATION period at seven levels, in which at the five levels, weeds were allowed to grow for 10, 20, 30, 40 and 50 days after crop emergence and then weeds were removed manually until harvest. In addition two control treatments (weed free and weedy check) were also considered.Each plot consisted of four rows (eight meter per row) with row spacing of 75 cm. In order to calculate the total dry mass accumulation, crop sampling was started 10 days after crop emergence and repeated for 11 times, at 10 days interval. YIELD AND YIELD COMPONENTS were determined at harvest. The results showed that the effect of WEED INFESTATION on total dry matter accumulation trend was started 40 days after emergence and about 90 days after reached to maximum. The effect of WEED INFESTATION on total dry matter, tuber yield, number of tuber per square meter and mean of tuber weight in commercial PLANT DENSITY was more than seed production PLANT DENSITY. The number of main stem was not affected by WEED INFESTATION in both plant densities.
