Dataset showcases rice quality traits influenced by long-term fertilization in double-cropping fields, suggesting implications for rice production.
Long-term fixed-site experiments are essential for investigating the effects of fertilization on crop quality. This dataset is derived from a long-term fertilization field experiment in the double-cropping rice fields of the red soil region in Jinxian County, Jiangxi Province. It systematically compiles rice quality data from the 2024 early and late rice crops, covering cooking and eating quality (amylose content, gelatinization temperature, gel consistency), processing quality (husked rice yield, milled rice yield, head rice yield), appearance quality (transparency, chalky grain percentage, chalkiness degree, grain length, grain shape), and nutritional quality (starch, fat, and protein contents). The data originate from field replicate samples under different fertilization treatments and were collected, analyzed, and documented according to unified protocols. This dataset serves as a valuable resource for research on the mechanisms of rice quality formation, optimization of fertilization strategies, and high-quality rice production in the red soil region.
