Standardisation of Suitable Super Absorbent Polymer Coating for Enhancing Seed Quality of Green Gram (Vigna Radiata L.)
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2019, Vol 9, Issue 3
Abstract
Changing climatic conditions accompanied with unpredictable rainfall leads to decreased available water to plants thus creating the drought conditions, which reflects on the yield of quality seeds. Hence, suitable technologies that can mitigate water deficit condition is vital. One of the innovative methods to overcome drought in order to meet sustainable food production is the use of Super Absorbent Polymers (SAPs) as a seed coating material. The present study was conducted to optimize the best concentrations of both synthetic (Sodium Polyacrylate and Polyacrylamide) and natural SAP for coating on green gram seeds. Results of the experiment revealed that among different concentrations of SAPs used, sodium polyacrylate, polyacrylamide and bio SAP @ 7, 2 and 8 g/kg of seeds respectively were noticed to have improved physiological performance over the control seeds (untreated seeds). Among the various SAP coating treatments, bio SAP recorded the highest speed of germination (7.1), germination percentage (88%), seedling length (35.7cm), dry matter production (0.199 mg/ 10 seedlings) and vigour index (3142).
