Abstract

A two-year (2022, 2023) field trial was conducted to explore the impacts of controlled-release nitrogen fertilizer (CRN) combined with Se fertilizer on the Se content, quality and yield of rice (Oryza sativa L.). Results showed that CRN combined with Se fertilizer significantly increased the Se content of rice (30.2–58.0 %). Notably, this increase was more substantial than that of the treatment common nitrogen fertilizer (CN) combined with Se fertilizer. Furthermore, it was found that irrespective of the application of Se fertilizer, CRN application could increase the net photosynthetic rate, nitrogen utilization, and actual yield (2.46–7.01 %) of rice. Moreover, it improved the processing and appearance quality of rice and increased the protein content, thereby enhancing its nutritional quality. However, the sole application of CRN significantly decreased the rice taste value. In contrast, Se fertilizer could effectively improve the eating quality of rice by reducing the amylose content. Overall, the fertilization strategy of combining CRN with Se fertilizer can enhance the Se content of rice and concurrently improve its yield and quality. This offers a reference for the development of Se-enriched rice.

期刊介绍： The Journal of Food Composition and Analysis publishes manuscripts on scientific aspects of data on the chemical composition of human foods, with particular emphasis on actual data on composition of foods; analytical methods; studies on the manipulation, storage, distribution and use of food composition data; and studies on the statistics, use and distribution of such data and data systems. The Journal''s basis is nutrient composition, with increasing emphasis on bioactive non-nutrient and anti-nutrient components. Papers must provide sufficient description of the food samples, analytical methods, quality control procedures and statistical treatments of the data to permit the end users of the food composition data to evaluate the appropriateness of such data in their projects. The Journal does not publish papers on: microbiological compounds; sensory quality; aromatics/volatiles in food and wine; essential oils; organoleptic characteristics of food; physical properties; or clinical papers and pharmacology-related papers.
