Soluble Silica as a Boon for Alleviating Toxic Effects of Heavy Metals on Vigna Radiata Grown Hydroponically in Sewage
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 5
Abstract
Toxic heavy metals present in sewage induce stress and negatively affect physicochemical and biochemical characteristics of plants. Silicon is beneficial metalloid, for increasing growth of plants especially under adverse conditions. The aim of the study is to evaluate role of soluble silica in reducing toxic effects of heavy metals. In present experimental design Vigna radiata (Mungbean) plants were grown hydroponically for 30-days in sewage and sewage enriched with soluble silica as AgriboosterTM. Effect of silica was investigated, in terms of growth attributes and biochemical characteristics of V.radiata. Results showed that, enrichment of sewage with silica has prevented heavy metal (Lead) accumulation, improved Na+/ K+ ionic balance, and significantly increased (p <0.05) dry weight, carbohydrate content as compared to control. Significant increase (p<0.05) in root length, shoot length and chlorophyll b was observed when sewage was supplemented with silica as compared to sewage. Total chlorophyll and protein content increase was highly significant (p <0.01) on supplementation of sewage with silica as compared to sewage. It was concluded from present study, that soluble silica can reduced toxic effects of heavy metal on V.radiata and improved its quality in terms of sugar and protein content.
