Effect of N and Si on Growth, Yield and Quality of Rice var. MTU-7029

“Rice is a staple food for millions of people around the world, and its production is crucial for food security. In order to sustain rice production and meet the increasing demand, it is important to understand the factors that influence the growth, yield, and quality of rice. One such factor is the availability of essential nutrients like nitrogen (N) and silicon (Si).”

The Role of Nitrogen and Silicon in Rice Production

Nitrogen is a vital nutrient for rice plants as it plays a key role in their growth and development. It is a major component of chlorophyll, which is essential for photosynthesis. Nitrogen also promotes the formation of proteins, enzymes, and other important molecules in rice plants. Adequate nitrogen supply enhances the vegetative growth of rice, leading to increased tillering, leaf area, and biomass production.

On the other hand, silicon is a beneficial element for rice plants that is often overlooked. It is taken up by the roots and deposited in the cell walls, strengthening them and providing structural support. Silicon also enhances the plant’s resistance to various biotic and abiotic stresses, such as diseases, pests, and drought. Additionally, silicon improves the quality of rice grains by increasing their weight, size, and resistance to lodging.
