Description ABSTRACT
The present investigations entitled, “Weed management in chrysanthemum (Chrysanthemum morifolium Ramat.)” were undertaken in the experimental field area of the Department of Floriculture and Landscaping, Punjab Agricultural University, Ludhiana during 2013-2014 to study the effect of different pre-emergence herbicides and different types of mulching materials on weed population, vegetative and floral parameters of chrysanthemum cv. Garden Beauty. Three pre-emergence herbicides viz. Butachlor, Atrazine @ 1 kg/ha, 1 kg/ha + 2 HW, 1.5 kg/ha and Pendimethalin @ 0.75 kg/ha, 0.75 kg/ha + 2 HW, 1.0 kg/ha along with weed free and weedy control treatments were tried in chrysanthemum. Eleven different treatments with three replications were compared in terms of weed population, growth and floral characters. The result of experiment showed that butachlor 1 kg/ha + 2 HW was found to be the effective weed control method for controlling weed population. Weed free treatment resulted in the maximum plant height (68.22 cm), plant spread (38.27 cm), number of branches per plant (5.89), number o flowers per plant (70.37) and duration of flowering (21.77 days). Among the different herbicides tried, butachlor 1 kg/ha + 2 HW gave the maximum plant height (65.53 cm), plant spread (35.27 cm), number of branches per plant (5.56), number of flowers per plant (67.50) and duration of flowering (20.71 days). In another experiment, eleven different treatments comprising different types of mulching material (black and clear polythene sheet and paddy straw) were compared. Among the different mulching material used, mulch with black polythene 150 µm showed better results with effective weed control and improved growth and floral parameters. This treatment showed the maximum plant height (66.67 cm), plant spread (41.77 cm), number of branches per plant (5.55), number of flowers per plant (71.56) and duration of flowering (21.22 days). Weed free treatment also showed better results with maximum plant height (67.00 cm), plant spread (42.22 cm), number of branches per plant (5.78), number of flowers per plant (72.11) and duration of flowering (22.00 days). Out of 14 weed species, Cyperus rotundus, Phyllanthus niruri and Parthenium hysterophorus were not controlled by any herbicidal or mulching treatments in the experiment.
