Evaluation and Screening of Nitrogen Efficiency at Seedling Stage of Rice Germplasm Resources
: Excessive nitrogen fertilizer application increases production costs and environmental burdens in rice cultivation, highlighting the need to identify low-nitrogen-tolerant germplasm. In this study, 266 rice accessions were evaluated in hydroponic culture for 35 d under normal-nitrogen conditions (NN: 1.6 mM NO 3 − an...
