Abstract

A field experiment was carried out in the kharif seasons of 2022, to study the screening attributes for determining the optimal concentration of Silixol (0.6%) and selecting high-performing rice genotypes to assess the impact of drought on morpho-physiological characteristics and yield attributes of rice genotypes. Eight rice genotypes were subjected to several treatments including control, drought during blooming, foliar application of Silixol with irrigation and foliar application of Siliconl (Silixol 0.6%) during drought. Application of Silixol in all genotypes exhibited the best total dry matter production and leaf area index, relative water content and yield attributes compared to other treatment in the study, both in drought conditions and with foliar Siliconl spray during drought. KRH-1 had the highest number of productive tillers under drought conditions and foliar Siliconl spray. US-312 achieved the highest grain output in drought conditions. These genotypes are recommended for drought-prone regions, and their yield potential can be enhanced by applying Siliconl foliar spray during the flowering stage under drought conditions. After analysing the recorded parameters, it has been concluded that further biochemical assessment of rice under application of Silixol is needed for ultimate concentration and genotype selection

Conclusion

The findings showed that drought stress has a substantial impact on the growth, physiological characteristics and production of rice. The application of Silixol has improved the morphological features and production of rice in both well-watered and water stress circumstances by reducing the deleterious effects of drought stress. Thus, including silicon into breeding efforts is essential to enhance yield quality and develop drought-resistant rice varieties
