Does an increase in available nitrogen during the seed-filling period improve soybean seed physiological quality under field water deficit?

Abstract

Increasing or maintaining yield and seed physiological quality under water deficit (WD) conditions is challenging for agriculture under the current climatic change scenario. The aim of this study was to evaluate the increase in nitrogen (N) availability on seed physiological quality under water deficit (WD) during seed filling in soybean genotypes contrasting in seed protein concentration.
