Abstract
The rice variety 'RD43' produces white grains with superior dietary characteristics, medium to low levels of apparent amylose content and rapidly available glucose.In this study, we investigated the effects of chitin-based bio-stimulant (CB) on growth, yield components, starch properties, total protein content, and antioxidant capacity of 'RD43' rice grown in a pot system.Two types of CB were developed: Type I CB derived from fermented shrimp shell with Bacillus licheniformis SK-1 mixed (FC) with rice bran, and Type II CB derived from FC blended with rice bran and rice husk.Both Type I and Type II CB were applied to soil at concentrations of 0.01%, 0.1%, and 0.2% (w/w), whereas the general practice without soil supplements was used as a control.The application of 0.2% Type II CB resulted in the maximum tiller number and the rice yield enhancement of 69.8%, while 0.2% Type I CB application increased the yield by 56.8%.This was attributed to the increase in the number of spikelets and filled grains per panicle without the increase in panicle number per plant.While neither type of CB application affected starch properties or protein content, 0.2% Type II CB significantly increased the antioxidant activity of brown seeds.These findings reveal that CB application can boost the yield of 'RD43' rice and preserve starch quality and protein content.Moreover, the enhanced antioxidant activity further underscores the CB potential to elevate 'RD43' rice as a functional food, supporting both yield and health benefits in rice production.
