Impact of crop weed competition on growth and yield of mulberry (Morus alba).

摘要

The effect of crop weed competition on growth and yield of mulberry was assessed during 2010-11 at Department of Sericulture, GKVK, Bangalore. The pooled data of two years revealed that weed free period of 75 days improved the growth characters viz., plant height (119.44 cm), number of shoots per plant (13.10), number of leaves per plant (138.80), leaf area per plant (4825.38 cm2) and dry weight per plant (22.85 g) significantly as compared to weed free period of either 60 days or less and weedy check. Consequently, leaf yield of mulberry was significantly higher in plot kept free up to 75 days after pruning (6446 kg/ha) as compared to other weed free period and weedy check. All growth characters showed positive correlation with mulberry yield.
