“…In general, the reduction in rice yield in the hot season was larger and the individual yield components contributed more evenly to it than in the wet season. This has been also evident that potassium application to rice under saline soil increased grain yield by 49% compared to the control (Akter et al, 2023). Increasing the level of potassium application from 24 to 72 kg K 2 O/ha increased rice yield on saline soils (Zayed et al, 2007;Zaina and Ismail, 2016) validate the present study findings.…”

“…Increasing the level of potassium application from 24 to 72 kg K 2 O/ha increased rice yield on saline soils (Zayed et al, 2007;Zaina and Ismail, 2016) validate the present study findings. Akter et al (2023) reported an increase in biological and grain yield by 20 and 14 % with the application of 57 kg K 2 O/ha in rice crop under salinity stress respectively over the control. The study also found that higher levels of K (114 kg K 2 O/ha) caused some reduction in both parameters by about 5.5 and 4.0%, respectively.…”

Background: Potassium (K) is an essential macronutrient, improves rice yield and contributes to salt stress tolerance. This study determined the best potassium (K) application level on yield formation and the saline resistance capability of rice under salinity field conditions of central Vietnam. Methods: Experiments were comprised of five K fertilizer application rates (0, 25, 50, 75 and 100 kg K2O/ha) and two rice varieties, viz, OM8104 and MNR3 for two growing seasons of 2021 and 2022. All treatments were arranged in a split-plot design with 3 replicates in Duy Vinh commune, Duy Xuyen district, Quang Nam province. Result: Potassium application affected the number of panicles per unit area, filled grain per panicle and actual grain yield of both rice varieties in both seasons under saline condition. Application of 50 kg K2O/ha reduced the soil salinity over the monitoring periods compared to the other K rates. EC values of soil were significantly higher during the hot season than the wet season showing high temperature effects. Application of 50 kg K2O/ha also accumulated maximum dry matter at different crop stages and produced the highest rice yield with 7.57 and 5.25 tons/ha for OM8104 and 7.35 and 5.18 tons/ha for MNR3 in both wet and hot seasons respectively. The harvest index could not affect significantly by K application irrespective of seasons and varieties. These increases in actual grain yields using 50 kg K2O/ha were attributed to increased filled grains per panicle, accumulation of high K+ content and K+/Na+ ratios in rice varieties in both seasons under saline field condition.

Nitrogen-use efficiency (NUE) of crops is critical for addressing global food security in response to climate change effects. The objective of our study was to evaluate the effects of N fertilization integrated with crop residue management to optimize NUE of crops. A replicated 2 x 4 split-plot experiment in randomized complete block design was conducted during the 2020–2022 on farmers’ fields at Bogura, Cumilla, and Mymensingh sites of Bangladesh. The main plots were two levels of crop residues (no residue, NR vs. 30% residue, CR) combined with sub-plots of four levels of N fertilizers (control, CL; farmers’ practice, FP; national recommended dose, RD, and 125% of RD, 125RD) on potato (Solanum tuberosum, L.), maize (Zea mays, L.), and rice (Oryza sativa, L.) systems. N fertilization when interacted with residue retention progressively increased crop yield. Residue alone contributed significantly to increase NUE of potato and maize by 9 and 6%, respectively. The NUE of rice increased significantly, while the NUE of maize decreased with N fertilization. The comparison of NUE models suggested that the nationally recommended N fertilization should be adjusted to 169, 152, 187, 92, and 112 kg/ha for potato, maize, Boro, Aus, and Aman rice, respectively. For potato and Aman rice, the SNMI showed better results, whereas for Boro, Aus, and maize, utilizing both NUE and SNMI provided maximum benefit from N management.

Despite the important role of silicon (Si) for the better utilization of plant nutrients, it is not well understood how the combinations of Si and P (phosphorus) will behave as a co-fertilizer in saline soil for better yield performance and nutrient uptake. Hence, the goal of this study was to identify the effects of different combinations of Si and P applications on the growth, yield, nutrient uptake including nutrient use efficiency of rice (Oryza sativa L.) in saline soil. Combinedly, 3 levels of silicon (Si), i.e., Ca2SiO4: 0, 300 and 600 kg Si ha− 1 and, 4 levels of phosphorus (P), i.e., TSP: 0, 13.2, 26.4, and 39.6 kg P ha− 1 were applied to salt-tolerant rice (Binadhan-8) variety. The results revealed that the significant effect of the Si and P combination improves the growth, and yield parameters (tiller number, filled grain, total grain, grain yield, biological yield, straw yield). We also found a strong positive correlation between the Si and P combination and other essential nutrients (N, P, K and S) implying that the interactive effects of Si and P fertilization improve nutrient uptake and increase nutrient use efficiency. Comparing all results, the combination of 300 kg Si ha− 1 and 26 .4 kg P ha− 1 is potentially optimum to maximize grain yield by 41.66% and straw yield by 55% and N uptake by 216%, P uptake by 193%, K uptake by 263% and S uptake by 130% over control in saline soil.
