Abstract

An experiment was carried out to evaluate the effects of graded shade levels on the growth and quality of Dracaena sanderiana var. ‘Celes’ in Batticaloa district of Sri Lanka. Graded shade levels were defined as treatments viz. 0% (T1), 50% (T2), 60% (T3), 70% (T4), and 80% (T5). The experiment was arranged in a completely randomized design with three replications. Experimental location was Crop Farm, Eastern University, Sri Lanka. Recommended agronomic practices were followed uniformly for all treatments. Plant height, leaf area, and plant biomass were measured at monthly interval and quality of cuttings was assessed at 3 months after transplanting. Analysis of Variance was performed to determine significant difference among treatments (p < 0.05). Plants grown at 70% shade level showed significantly (p<0.05) better performance in measured growth parameters viz. plant height, leaf area and biomass while the lowest performance was observed in plants grown at 80% (T5) shade level and open field condition (T1). In quality assessment, plants subjected to 70% shade received significantly (p<0.05) highest score. Plants grown at 70 % shade level would have received optimum amount of irradiation in this experiment. In conclusion, it could be stated that, 70% shade level is optimum for growing Dracaena sanderiana var. ‘Celes’ in the Batticaloa district of Sri Lanka.
