Hybrid rice typically surpasses conventional in terms of biomass, yield, and stress resistance, whereas developing utilizing saline–alkali-tolerant hybrid is crucial to obtain crop harvests from salt-affected soils. In the present study, varieties (paternal parents), i.e., Hua-Zhan 9311, four varieties, Xiang-Liang-You-Hua-Zhan, Jing-Liang-You-Hua-Zhan, Guang-8-You-Hua-Zhan, Y-Liang-You-1-Hao, denoted as V1, V2, V3, V4, V5, V6, respectively, received an application two salt levels, 0% 0.3% saltwater irrigation, during 2022–2023. The results reveal that V1 (parental parent) had highest tolerance index, which was significantly greater than its V5. Moreover, index V2 also (V6). lower might be owing relative loss number effective panicles, total grains per panicle, seed setting rate, thousand-grain weight. our study revealed appearance different enhanced at a concentration 0.3%. Among all cultivars, largest reductions chalkiness chalky grain rate were observed 81.13% 63.49%, well 84.03% 87.53%, respectively. protein sodium contents sodium-potassium ratio cultivars increased under stress; however, no significant effect on cooking or sensory quality noticed saline conditions. Overall, negatively affected yield quality, but more salt-tolerant rice, harnessing heterosis improve saline-tolerant rice.

Soil salinization poses a serious threat to global food security, as high Na+ contents in soils hinder nitrogen use efficiency (NUE), affecting the growth and yield of crop plants. The present study aims explore effects different fertilizer types viz., NO3- (N1) NH4+ (N2) planting densities, D1: 30 × 10 cm, D2: 20 D3: on development, absorption utilization, formation. salt-tolerant rice variety 'Jingliangyou 3261' was exposed 0.3% salt irrigation water. Results revealed that N2 substantially improved by increasing number effective panicles rate grain-setting compared N1. In addition, also increased leaf chlorophyll content, dry matter accumulation, antioxidant enzyme activity such superoxide dismutase, peroxidase, catalase reduced content malondialdehyde. comparison with N1, treatment resulted an increase 12.21%, 31.89%, 37.53% total recovery (NRE), agronomic (NAE), respectively. This can be attributed enhanced metabolic activity, including nitrate reductase glutamine synthetase, more robust root system. Under N1 conditions, D3, D1 tillers but decreased percentage productive tillers, grains per panicle, grain-filling rate, thousand-grain weight, thereby reducing yield. Additionally, D3 significantly NRE NAE treatment. Therefore, rational selection type density (D3) is crucial for improving rice. would broaden scope agricultural solutions saline soils, potentially security regions where soil widespread issue.

The present study aimed to investigate the effects of different soil amendments coupled with nitrogen fertilizer on morpho-physiological characteristics and yield salt-tolerant rice under saline conditions. amendments, i.e., S1: zeolite amendment, S2: coconut coir S3: humic acid S0: no treatments, N1: urea, N2: slow-release N0: N fertilizer, were kept in main plots sub-plots, respectively, a split-plot design. variety 'Shuangliangyou 138' was exposed 0.3% salt irrigation water. results showed that during entire growth period, compared S0, S1 S3 treatments increased SPAD values by an average 6.3%and 5.5%, leaf area index 24.5% 19.8%, canopy interception rate 11.5% 4.1%, aboveground biomass 36.8% 13.9%, respectively. Moreover, conditions, tiller number per square meter, water potential, content, chlorophyll contents also improved urea than urea. promoted root vitality nutrient absorption as well enhanced activity antioxidant metabolism enzymes In sum, rational application could improve productivity saline-alkali land.
