Among the weed control treatments, the minimum weed count (35.50), fresh weight (22.78 g), and dry weight (7.51 g) of weeds/m2 were recorded with the treatment pendimethalin @ 1.0 kg a.i. ha -1at 75 days after transplanting. Various vegetative and flowering characteristics like maximum plant height at first bud appearance, number of branches plant-1, plant spread, minimum days taken to colour break stage, days taken to full bloom stage, duration of flowering, number of flowers plant-1, flower diameter,rnweight of loose flowers plant-1, yield of loose flowers ha-1 and vase life were improved at the application of pendimethalin @ 1.0 kg a.i. ha-1.
