Abstract
This study evaluated the effects of various mulch types on weed management, soil moisture conservation, and crop performance in Gladiolus hybridus cv. Punjab Glance at Punjab Agricultural University, Ludhiana. The experiment tested different coloured polythene mulches—black (25µ), silver on black (25µ), transparent (25µ), and white (50µ)—as well as paddy straw mulch at the rate of 10, 15, and 20 tonnes/ha, and pendimethalin (0.5 kg/ha). Results demonstrated that transparent and white polythene mulches promoted earlier sprouting, bud initiation, and flowering. Black polythene mulch yielded the tallest plants (90.30 cm) and longest spikes (75.31 cm), while white polythene (50µ) mulch produced the most florets per spike (12.39) and extended the flowering duration (15.60 days). Hand-weeding achieved the highest weed control efficiency (100%), closely followed by black polythene mulch (99.87%). Paddy straw mulch (1 t/ha) was the most effective for soil moisture conservation, with polythene mulches also performing well. Transparent (25µ) and white (50µ) polythene mulches recorded the highest average soil temperatures during the study.
