Abstract:

Intending to scrutinize the influence of silicon (Si) on the yield attributes of rice under well-watered and water-deficit conditions, a field trial for two successive years (2017 and 2018) was laid out in split- plot design with four treatments viz. Control (T1), Si fertilization (T2), Si fertilization + Drought stress (T3) and Drought stress (T4). The results distinctly validated positive significant correlation between silicon and the yield attributes such as panicle weight (flowering and maturity) and harvest index in rice under well-watered conditions. Through further investigations, we could state that the panicle weight at flowering and maturity, test weight and harvest index which declines significantly under water deficit conditions could be escalated by 49.12%, 30% and 14.48% respectively through silicon applications. Commercial silicon fertilization could thus prove to be a vital manoeuvre in compensating the differences in yield attributes under adverse climatic conditions leading to fruitful and viable crop growth.
