Assessing the Effect of Basalt Rock Fines, Activated Humic substances and Its Interaction on Rice Growth and Yield

Rabbany A, Bhadha JH, Barbier M

Silicon known as a beneficial nutrient in the cultivation of rice, playing a key role in photosynthesis enhancement, and tolerance to biotic and abiotic stress. The present study aimed to examine available Si content from rice plant tissue and soil from an experimental area located at Butte county as affected by basalt fines, humic substances and its interaction in a single product containing both materials. The study was performed in trays contained in plastic tubs. Results from this study suggests that there is a positive interaction between basalt and humic substances and that the interaction of these materials in a single product have the potential to increase rice yield grains by 20%.
