Effect of Native Cassava Starch-Poly (Sodium Acrylate-co-Acrylamide) Hydrogel on the Growth Performance of Maize (Zea may) Seedlings

摘要

The physical mixture of native cassava starch and PAN was hydrolyzed by NaOH solution to yieldstarch-poly(sodium acrylate-co-acrylamide) superabsorbent hydrogel. The agricultural performance of the hydrogel – soilmixture samples in which maize seedlings have been planted were measured as a function of hydrogel loading and comparedwith the values obtained in the control in which hydrogel was not added. The results of the soil-hydrogel analysis at a monthlyinterval showed that there was significant increase in the ability of the soil to retain moisture and also the increase in thegrowth performance of the maize seedlings compared to the control
