“…BC at 2% improved wheat growth and increased its height by 11% (Kanwal et al, 2018), while 5 % BC under salinity improved soil fertility and increased sorghum biomass yield by 25 % (Edmunds, 2012). In addition, 1.5, 3.0 and 4.5 % BC in saline-sodic paddy soil reduced stress and promoted rice yield (Jin et al, 2018), while BC improved the legume yield in the calcareous soil in arid area (Azeem et al, 2016). Diatta (2016) reported that 20 tons BC/ha could improve soil fertility and crop productivity in temperate soils but had limited effects on sandy, salt-stressed soils may be due to differences in soil properties.…”

T HE DROUGHT is one of the most important abiotic stresses limiting the crop productivity especially in sandy soils in arid and semi-arid areas. So, using soil amendments such as vermicompost (VC), biochar (BC), and polymer (PL) are more important in these areas. Lysimeter experiments with sandy soil were carried out at Sakha Agric. Res. Station, Kafr El-Sheikh, Egypt to study the effect of 0.4% PL, 4.0% VC and 1.0% BC (W:W soil) on productivity of wheat (2018/019) and maize (2019) under two irrigation levels (irrigation after depletion of 50% and 75% from soil moisture. The obtained results indicated that irrigation at 75% moisture depletion (irrigation deficit) decreased plant height, 100-grain weight, grain and straw yields, water applied to wheat (-16.8%) and maize (-20%) compared to that with higher irrigation level (50% depletion). Also, water productivity was slightly decreased for wheat, but it slightly increased for maize and ECe values were slightly increased due to irrigation deficit. Also, applications of soil amendments and their combinations significantly increased plant height, 100-grain weight, yield and water productivity of both crops and improved soil porosity and field capacity. The VC was more effective treatment followed by BC and PL treatments, while their interactions were the most effective on these parameters. Moreover, soil amendments alleviated the deleterious effects of irrigation deficit on plant growth and salt accumulation. Finally, applying BC combined with VC and PL could be recommended as a good approach to maintain long-term productivity of sandy soils and mitigate the hazardous effects of drought stresses.

“…Rice ( Oryza sativa L.), an important food crop worldwide, is used as a desalinization crop in saline‐alkaline soils (Lv et al., 2013). During rice cultivation, the ground is submerged for a long period, and the water washes salts from the soil, gradually reducing the concentration of salts and improving the soil (Jin et al., 2018; Safi‐naz, 2016). Therefore, planting rice in sodic soils not only improves soil salinity but also increases rice yield, which is important for food security.…”

Soil salinity and alkalinity are key abiotic stresses that limit crop growth and yield worldwide. Balanced N fertilization is important for improving rice (Oryza sativa L.) yield via efficient utilization of P and K under saline and alkaline soil conditions. In this study, a japonica rice cultivar, Kenjing 8, was used to investigate the effects of N fertilizer on rice yield, as well as N, P, and K status, in a 2‐yr field experiment in saline‐alkaline soil in Heilongjiang Province, northeast China. The plants were assigned to the following five treatment groups: no N fertilizer, or conventional, balanced, reduced, and postponed N fertilizer management. Compared with conventional N management practice, balanced and reduced N management practices increased the concentrations of N, P, and K in the leaves, stem‐sheaths, and panicles at full heading (FH) and maturity; however, postponed N management led to the opposite results. Balanced N management increased N, P, and K mobilization to the leaves (from FH to maturity) by 49, 43, and 67%, respectively, resulting in the highest crop yields among all the N management practices studied. Furthermore, rice yield was positively correlated with N, P, and K accumulation and rates of nutrient mobilization to the leaves, stem‐sheaths, and panicles at maturity. The application of 150 or 135 kg N ha−1, and the proportion of 4:3:1:2 in the pre‐transplanting, mid‐tillering, panicle initiation, and panicle differentiation stages, may increase rice yield and facilitate efficient utilization of nutrients in saline‐alkaline soil.

“…The authors' experiments also consistently found that under saline-sodic paddy soil, K + and K + /Na + ratio in rice root system was increased significantly (Fig. 2), thus improving cell membrane integrity, increasing water potential, and enhancing salinity tolerance and growth of rice (Jin et al 2018;Ran et al 2020). Yue et al (2016) also found that biochar application could accelerate salt leaching, lower soil EC, and provide a good environment for growth and development of plant roots.…”

Saline-sodic soil is one of the major threats to crop growth, production, and quality. Biochar amendment could alleviate the adverse impacts of saline-sodic stress in crops. However, the effect of biochar on root morphological, root physiological functions, and rice yield in saline-sodic paddy soil has not been studied. Here, the underlying mechanisms of positive effects in morphological characteristics and physiological functions of rice roots under heavily saline-sodic paddy soil amended with biochar were evaluated. The soil was amended with biochar at zero-biochar (CK), 15g kg-1 soil (T1), 30 g kg-1 soil (T2), or 45 g kg-1 soil (T3). Biochar addition significantly increased root length, root volume, root dry weight, and root-shoot ratio at all growth stages. The root absorption vigor and root oxidization capacity were enhanced and increased significantly by decreasing Na+/K+ ratio, MDA content, and increasing K+ concentration in rice root after biochar amendment. The root bleeding rate of biochar treatments at different growth stage were 11.01% to 67.73% greater than these of CK. The yield of rice was increased significantly under saline-sodic paddy soil after biochar amendment. It was concluded that biochar had positive effect on the morphological characteristics and physiological functions in rice roots in saline-sodic paddy soil.
