“…As a result of separation, the soil is differentiated by structural composition. By combing, the stratifier PRSM-5 removes a sufficient amount of productive moisture in the seed layer of the soil (De Moraes et al, 2020;Ferreira et al, 2021;Yue et al, 2021). Excessively loosened soil after ploughing in arid conditions quickly loses moisture, which significantly reduces the density of herbage and further yield (Troyanovskaya et al, 2019;Troyanovskaya et al, 2021).…”

For seed germination and the formation of a good soybean crop, significant reserves of soil moisture are required, which depends on the autumn-winter soil preparation, weather conditions and planting dates. The purpose of this study is to identify the impact of the main tillage technology on its agrophysical properties and conditions for the growth and development of soybean plants. Experimental crop rotation: soybean – winter wheat was carried out under favourable (hydrothermal coefficient 1.46) and dry (hydrothermal coefficient 0.66–0.87) weather conditions. The main tillage was carried out with a stratifier PRSM-5 to a depth of 15–17 cm or a chisel plough PCh-2.5 to a depth of 25–27 cm, with additional pre-sowing or post-sowing rolling with a ring-spur roller KKSH. Sowing was carried out at a depth of 10 cm with stable heating of the soil in three periods: the first at 8–10 °С, the second at 10–12 °С, and the third at 12–14 °С. As a result of evaluating the influence of various factors, it was found that under favourable conditions, the highest seed productivity of soybean plants (1.91–1.96 t·ha−1) was formed after treatment with the stratifier PRSM-5 at the first sowing period and at the second sowing period after chisel ploughing with additional soil compaction. In dry weather conditions, pre-sowing treatment with a stratifier PRSM-5 had an advantage in seed productivity by 7–12% compared to ploughing with a chisel plough PCH-2.5.

“…This approach is advantageous for highthroughput analysis of root samples, enabling the swift collection of root RSA traits in the eld, aiding the selection of ideal RSA varieties in controlled environments. It has been widely adopted in diverse crops, including corn [32,33], soybean [34], wheat [35], etc. However, despite the widespread application of 'shovel omics' in various crops such as maize, wheat and soybean, its application in the eld research of cotton RSA is still a novel method.…”

Background: Root system architecture (RSA) exhibits significant genetic variability and is closely associated with drought tolerance. However, the evaluation of drought-tolerant cotton varieties based on RSA in the field conditions is still unclear. Results: So, we conducted a comprehensive analysis of drought tolerance based on physiological and morphological traits (i.e., aboveground and RSA, and yield) within a rain-out shelter, with two water treatments: well-watered (75 ± 5% soil relative water content) and drought stress (50 ± 5% soil relative water content). The results showed that principal component analysis identified six principal components, including highlighting the importance of root traits and canopy parameters in influencing drought tolerance. Moreover, the systematic cluster analysis were used to classify 80 varieties into 5 categories, including drought-tolerant varieties, weak drought-tolerant varieties, intermediate varieties, and weak drought-sensitive varieties, drought-sensitive varieties. Further validation of the drought tolerance index showed that the yield drought tolerance index and biomass drought tolerance index of the drought-tolerant varieties were 8.97 and 5.05 times higher than those of the drought-sensitive varieties, respectively. Conclusions: The RSA of drought-tolerant varieties was characterised by a significant increase in average length-all lateral roots, a significant decrease in average lateral root emergence angle and a moderate root/shoot ratio. In contrast, the drought-sensitive varieties showed a significant decrease in average length-all lateral roots and a significant increase in both average lateral root emergence angle and root/shoot ratio. It is therefore more comprehensive and accurate to assess field crop drought tolerance by considering root performance.

“…On the other hand, macroporosity refers to the porosity of the soil in relation to the larger spaces between particles, where water and air can be stored and circulate freely [101][102][103][104][105][106]. Reduced macroporosity related to depth may indicate soil compaction at the layers, affecting the movement of water and air and, consequently, the development of the root system [107][108][109].…”

Studies on the development of the root system can provide important information about responses to different management strategies, such as the use of lower quality water, also evaluating the interaction between plants and the physical properties of the soil. This study tested the hypothesis that irrigation with treated sewage effluent (TSE) supplies the water needs of sugarcane plants, increasing root growth and improving the physical properties of the soil. We evaluated the effects of subsurface dripping with TSE or surface reservoir water (SRW) on the root development of first ratoon cane (Saccharum officinarum L.) and the physical properties of dystrophic red latosol. Irrigation treatments were applied at 20 and 40 cm and soil properties were evaluated at soil depth layers of 0–20, 20–40, 40–60, and 60–80 cm. We verified that under irrigation with TSE and SRW, shallower soil layers present better porosity, soil aggregation, and aggregate stability conditions, parameters that improve the root system development and plant growth. On the other hand, deeper soil layers have lower macroporosity and higher total clay volume, indicating the possibility of compaction and greater limitations for sugarcane root growth. These results are important for understanding soil quality and provide significant information for agricultural management and for the implementation of sustainable soil conservation practices. This study shows the efficiency of TSE as an alternative water source for sugarcane crops.
