Abstract


Recent studies demonstrated the beneficial effects of silicon (Si) on the growth and development of many graminaceous plants. Exogenous application of Si on growth, yield and nutrient status is not known for finger millet (Eleusine coracana (L.) Gaertn.), therefore in the present study, efforts have been made to assess the localization of Si in different plant parts of the finger millet. In addition to this, the attempts were made to evaluate the effect of exogenous application of Si on growth, yield, and nutrient status in finger millet. Finger millet readily absorbs the Si and accumulate it in the aerial organs, predominantly in leaves. Exogenous supplementation of silicon significantly improved all the attributes of plant growth and yield. Si supply alters the status of significant nutrient such as carbon (C), nitrogen (N), and oxygen (O) in different plant parts. There is a negative correlation between Si content and C content in all the plant tissues examined. Silicon has got positive impact on the accumulation of nitrogen and oxygen content in different plant tissues. To the best of our knowledge, this is the first report on Si accumulation and its influence on growth, yield, and mineral accumulation such as carbon, nitrogen, and oxygen.
