Agronomic strategies for improving rice protein quality through integrated nitrogen and water management under SRI


Madane Ananda Jagannath and J Bhavadheesh Varma

Rice is a staple food for more than half of the global population, yet its protein quality remains a nutritional concern due to its limited lysine content and overall low protein concentration. Agronomic practices, particularly nitrogen (N) fertilization and irrigation management, play a pivotal role in determining not only rice yield but also its nutritional quality. This study investigates the impact of different irrigation regimes and nitrogen levels on the protein content and amino acid profile of rice grains under field conditions. Results indicate that moderate to high nitrogen application significantly enhances total grain protein content, in grain (7.89 and 7.92%) and straw (4.04 and 4.12%) was recorded with scheduling of irrigation at two days after disappearance of ponded water as compared to rest of the irrigation scheduling during both the years Similarly, application of 100% RND + BGA recorded the maximum protein content and protein harvest over the other treatment but remained at par with 100% RDN + Sesbania aculeata co-culture in respect of protein content but significantly higher than 100% RDN alone treatment during both the years of study The findings suggest that water and nitrogen management strategies can be optimized to improve both yield and protein quality of rice, contributing to nutritional security and sustainable rice cultivation. This study underscores the importance of agronomic interventions in enhancing the functional quality of rice grains beyond mere yield optimization.
