“…These findings give insights into the beneficial effects of humic acid on Giza 179 plant growth under nonsaline and saline conditions. Similar growth-promoting effects of humic acid have been reported in other rice cultivars [26,27], soybean seedlings [28], and maize [29]. These findings are supported by the results of PCA analysis (Figure 4A) that revealed differences between humic acid-treated and non-treated rice plants growing in non-saline and saline conditions.…”

The sensitivity of rice plants to salinity is a major challenge for rice growth and productivity in the salt-affected lands. Priming rice seeds in biostimulants with stress-alleviating potential is an effective strategy to improve salinity tolerance in rice. However, the mechanisms of action of these compounds are not fully understood. Herein, the impact of priming rice seeds (cv. Giza 179) with 100 mg/L of humic acid on growth and its underlaying physiological processes under increased magnitudes of salinity (EC = 0.55, 3.40, 6.77, 8.00 mS/cm) during the critical reproductive stage was investigated. Our results indicated that salinity significantly reduced Giza 179 growth indices, which were associated with the accumulation of toxic levels of Na+ in shoots and roots, a reduction in the K+ and K+/Na+ ratio in shoots and roots, induced buildup of malondialdehyde, electrolyte leakage, and an accumulation of total soluble sugars, sucrose, proline, and enzymic and non-enzymic antioxidants. Humic acid application significantly increased growth of the Giza 179 plants under non-saline conditions. It also substantially enhanced growth of the salinity-stressed Giza 179 plants even at 8.00 mS/cm. Such humic acid ameliorating effects were associated with maintaining ionic homeostasis, appropriate osmolytes content, and an efficient antioxidant defense system. Our results highlight the potential role of humic acid in enhancing salt tolerance in Giza 179.

“…In our study, the lowest grain yield was found in the L treatment among the soil amendment treatments, although the combined application of L and F could significantly improve the grain yield of winter wheat in a winter wheat–summer maize rotation. This is mainly due to the ability of L to provide a large amount of carbon and F to improve soil microbial activity (Matuszak‐Slamani et al, 2017). Thus, the combined treatments can improve soil nutrient availability and crop yield.…”

Effects of the combined application of biochar and humic substances on the improvement of saline cropland in the Yellow River Delta of China

Soil salinization has become a global environmental problem with the potential to cause serious land degradation. Thus, improving salt‐affected soils and enhancing the nutrient utilization efficiency of saline farmlands through scientific and effective measures are urgent scientific problems. In this study, a 2‐year field experiment was conducted to evaluate the effects of different soil amendments and their combinations on the dynamics of soil salinity, soil nutrients, and crop yield in a moderately salinized soil (EC1:5 of 0.78 dS m−1 and total salt content of 3.06 g kg−1). Nine soil treatments were implemented: biochar (B), lignocellulose (L), humic acid (H), fulvic acid (F), biochar + humic acid (B + H), biochar + fulvic acid (B + F), lignocellulose + humic acid (L + H), lignocellulose + fulvic acid (L + F), and control (CK). The results demonstrated that the application of F led to a certain reduction on the contents of soil salt, Na+, and Cl− among the soils amended with a single amendment application. The combined application of B and F or H could increase the soil desalination rate and increase the mineral N and Olsen‐P concentrations at a soil depth of 0–20 cm, which improved the grain yield, biological yield, N recovery efficiency (REN), N agronomic efficiency (AEN), N partial factor productivity (PFPN), P agronomic efficiency (AEP), and P partial factor productivity (PFPP). Although the single application of L led to decreases in the grain yield, biological yield, REN, AEN, PFPN, REP, AEP, PFPP, and P physiological efficiency (PEP), the combined application of L and F had superior effects on enhancing the winter wheat grain yield and accumulative nutrient use efficiency. In conclusion, the combined application of B and F or H is recommended to ameliorate salt‐affected soils and improve nutrient availability.

“…A wide array of bio-stimulant compounds has been utilized to mitigate the salinity-induced injury to crop growth, development, and productivity. Humic acid reduces the salinity stress and increases the yield of many crop plants (Jarošová et al, 2016;Matuszak-Slamani et al, 2017;Saidimoradi et al, 2019). It positively affects multiple indices of plant growth including root and shoot growth, leaf photosynthetic pigments, yield, and its related traits (Osman et al, 2017;El-Beltagi et al, 2023).…”

Salinity stress is a major constraint for rice growth and productivity. Rice cultivars with considerable salt tolerant capabilities have been developed and improving their performance in the salt-affected lands is crucial. Herein, the effects of humic acid (100 mg/l) as a stress-alleviator and a biostimulant on the germination, vegetative growth, and yield of Giza 179 rice cultivar under increased salinity (0.55, 3.40, 6.77, 8.00 mS/cm) were investigated. The humic acidinduced effects were also validated in salt-affected field. Salinity retarded Giza 179 germinationrelated traits which were associated with a significant decline in Gibberellic acid (GA 3 ) content and α-amylase activity. Also, salinity reduced the Giza 179 vegetative growth which was correlated with accumulation of shoot Na + , proline, and total soluble proteins (TSP), induction of membrane injury, and reduction of photosynthetic pigments. Humic acid significantly decreased most of the salinity-induced injury; however, it increased the salinity-induced synthesis of proline and TSP. The deteriorative effects of salinity during germination and vegetative stages were translated into significant reduction in grain yield and quality whereas the ameliorative effects of humic acid against salinity were reflected in better overall growth and yield. These results indicate the efficacy of humic acid in maintaining vigorous germination, growth, and yield in salt-affected lands.
