Abstract
This research aims to study the effect of chitosan on 10 rice cultivars. Number of leaves, tiller number per plant, stem height, leaf area, photosynthesis and dry weight were analyzed. Seeding were immersed by chitosan concentration level at 0.01, 0.05 and 0.10 %w/v and transplanted in the tray for 14 days and further grew in 8 inch pot contained soil and sprayed with all those chitosan solution compared to the control group. The results showed the increasing of all studied factors. The concentration of chitosan at 0.05 %w/v would obviously cause more effect than chitosan concentration at 0.01 and 0.10 %w/v. Especially to the photosynthetic activity of RD41, RD49 and RD47, the activity increased up to 41.93, 37.80 and 34.05%, respectively compared to the control group. Also increasing of number of leaves, tiller number per plant, leaf area total dry weight and stem height. Overall, the application of chitosan to the growth of rice was significantly enhanced which affected to the photochemical reaction of rice especially to RD41, RD47, RD49 and PL2. Rice cultivars treated environmentally chitosan was an effective way to enhance and improve rice production.
