The present study “Study the effect of chemical, physical and cultural methods on growth and flowering parameters of rose (Rosa hybrida var. Konfetti)” was carried out at Floriculture Department Farm, Punjab Agricultural University, Ludhiana, during 2016–17 to study the effect of pre-emergence herbicides and different mulching materials on vegetative and floral parameters of Rosa hybrida var. Konfetti by using the following 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. The result of experiment showed that Black polythene mulch (200 μ) was found to be the very effective weed control method. Maximum plant height (44.57 cm), plant spread (36.77 cm), number of branches per plant (5.13), number of flowering buds (4.93), flowering diameter (6.49 cm) and length of flowering stalk (17.97 cm) and minimum days taken to flowering (37.71 days) and longer flowering duration (17.97 days) was observed under black polythene mulch (200 μ) treatment. The minimum value of all the observations recorded was found to be in the weedy check. Thus, the present investigation revealed that among all the mulch materials used, black polythene mulch (200 μ) was found most effective among all.
