An experiment was conducted during 2016-2017 at College of Horticulture SKLTSHU Rajendranagar, Hyderabad. The experiment was conducted in randomized block design with factorial concept with three replications. Factor I includes two varieties Kamini (V1) and Poornima (V2), factor II includes eight treatments viz., Pendimethalin (30EC), Oxyfluorfen (25EC) and Alachlor (50EC) as pre emergence herbicides in combination with Quizalofop ethyl (10EC) as post emergence followed by hand weeding at 20 DAT. The results revealed pendimethalin 0.1 kg a.i ha-1 followed by hand weeding at 30 DAT recorded significantly increased, number of flowers, yield and quality of flowers. This was followed by alachlor 0.1 kg a.i ha-1 followed by hand weeding at 30 DAT. While, unweeded control gave poor control of weeds and reduced plant growth, yield and quality of flowers. Days to first flower opening, 50% flowering, duration of flowering, flower diameter, fresh weight of flower, number of flowers plant-1, flower yield plant-1 (g) and t, and vase life exhibited maximum with pendimethalin (30EC) @ 1.0 kg a.i ha-1 followed by hand weeding. Which was followed by alachlor (50EC) @ 1.0 kg a.i ha-1 followed by hand weeding. Minimum days to first flower opening and 50% flowering were observed in Kamini, while Poornima has recorded maximum duration of flowering. Flower diameter, fresh weight of flower and flower yield plant-1 (g).
