Integrated weed management in rose

The effect of pre-emergence herbicides and different mulching materials on weed population, vegetative and floral parameters of Rosa hybrida var. Konfetti was studied by using the treatments, Black polythene mulch (200 μ), Paddy straw mulch (4.5 kg/m²), Pendimethalin 1.5 kg/ha, Pendimethalin 1.0 kg/ha, Pendimethalin 1.0 kg/ha + Paddy straw mulch (4.5 kg/m²), Hand weeding (Monthly interval) and Weedy check. During the crop season, maximum plant height (48.9 cm), plant spread (35.2 cm), number of branches per plant (7.6), number of flowering buds (9.5) were observed under black polythene mulch (200 μ) treatment followed by hand weeding treatment. Minimum value of weed count and dry weight of broadleaf weeds, sedges and grasses was in black polythene mulch (200 μ) followed by hand weeding treatment. It was concluded that black polythene mulch (200 μ) was more effective in improving soil hydrothermal properties, weed suppression, growth and flowering of Rosa hybrida var. Konfetti.
