Author(s): L. TRIPATHY, S.K DASH, D.K DASH. AND S. MURMU
Abstract: An experiment was conducted during 2011-12 and 2012-13 at All India Coordinated Research Project on Floriculture at Chiplima, Sambalpur, Odisha. Ten treatments with four pre-emergence chemicals in different concentrations were administered to spray chrysanthemum cultivar “Flirt” in three replications per treatment The data collected was pooled over for two years .The result depicted that the treatments varied significantly with respect to weed count per square meter, fresh weight of weeds and dry weight of weeds. Pendimethalin 1.00 kg a.i.ha-1was found to be most effective in controlling weed growth as compared to other treatments and Pendimethalin – 0.75 kg a.i.ha-1was at par with Pendimethalin 1.00 kg a.i.ha-1.The growth parameters like plant height, plant spread, number of sprays per plant, weight of flowers per plant, number of flowers per plant did not vary significantly with the treatments which suggest that the chemicals have no effect on the plants and can be used for controlling weeds in spray chrysanthemum.
