Silicon on rice seed yield and quality

The study aimed to evaluate the yield components and physiological quality of rice seeds produced, obtained from coated with rusk ash kaolin®. Treatments consisted coating two sources silicon (silicate aluminum-70% SiO2 (kaolin® husk ash- 95% SiO2) at doses 0; 30; 60; 90 120 g.100 kg-1 seed. Yield were evaluated: Seed per plant, number panicles plant plant. subjected germination, first count, total length, root seedling tests quality. provided no increase in seed However, there was an produced for cv.
