Abstract:
The present investigation was conducted during rabi season of 2020-21 under the supervision of college of Horticulture, Venkataramannagudem at College of Horticulture, Sirsi, (UHS, Bagalkot) Karnataka to study the effect of plant-based extracts on growth and weed suppression in lawn grasses. Eight plant-based extracts (Water, NLE @ 1.5%, NLE @ 3%, TPE @ 1.5%, TPE @ 3%, GTE @1.5%, GTE @ 3%, TLE @ 1.5% and TLE @ 3%) were selected for weed suppression ability and growth in Bermuda grass and Mexican grass. The experiment was laid out in factorial RBD replicated two times. Results revealed that the spraying of neem leaf extract (NLE) at 3% (T₃) has shown significantly minimum number of weeds, weed dry weight and maximum stolon length at 120 days after planting.
