Abstract
An experiment was conducted to evaluate the growth and development of turmeric under four different shade levels at Crop Farm, Faculty of Agriculture, Eastern University, Sri Lanka from September 2014 to March 2015. Treatments consist of, open field condition (T1) which was considered as 0% shade level, 50% shade level (T2), 70% shade level (T3) and 80% shade level (T4), were evaluated in completely randomized design. Agronomic practices were followed according to the recommendations of Department of Export Agriculture, Sri Lanka. Leaf area and plant biomass were measured bimonthly and yield was quantified at the end the experiment. Analysis of Variance was performed to determine significant differences among treatments (P < 0.05). Results indicated that leaf area, biomass and yield were significantly higher in T2 followed by T3 than T1.Higher radiation level would have caused destruction of photosynthetic pigments and hence reduction in growth. In the treatments of T3 and T4, the amount of solar radiation received by the plants are not sufficient for optimum photosynthesis. Therefore, it could be concluded that 50% shade level is suitable for the cultivation of turmeric in the Batticaloa district of Sri Lanka.
