Evaluation of super absorbent polymer effects in soybean (Glycine max L.) under water deficit conditions.

摘要

Applying a super absorbent polymer (SAP) to (Glycine max L.) seed could be economically beneficial for dry regions. Field trials at four locations were used to evaluate the effect of SAP and soybean cultivar on crop yield. The SAP was used to estimate the economic value of using water irrigation, two selenium treatments and soybean cultivar. SAP returns differed across locations. Chemical markers activity was lower for selenium and SAP treatments, compared to without the use of a SAP and selenium. The value of a malondi aldehide (MDA) was generally positive for water deficit and negative for selenium and SAP. However, at a location prone to water deficit spells during which seed germination could occur, the SAP generally had significant effect. Despite the SAP having a positive value for soybean yield in cooperation with selenium, its potential use will be limited because selenium with a SAP had good reflect to water deficit tolerance.
