Physiochemical characterization of rice genotypes based on gel consistency and alkali digestion under different N levels

Abstract

One crucial agronomic tool for regulating grain quality is nitrogen fertilizer. However, the impact of nitrogen application on grain quality during heading has not been well studied. Grain quality parameters, such as Gel Consistency (GC) and Alkali Digestion Value (ADV) responses to nitrogen fertilizer were determined in a field experiment. We found that GC and ADV decreased as the nitrogen application level at the heading stage. When considered collectively, our findings showed that GC and ADV increase in Pusa 44 in response to an elevated nitrogen content at the heading.
