“…It sticks to plant roots and increasing the water-holding capacity of soil, but when the soil moisture reduces as temperature rises, then hydrogels slowly release moisture back to the plants as it is needed (Wu et al, 2010). In this respect, many investigators found positive effect on growth characters of soybean plants when they were treated with some soil amendments such as hydrogel for plant height (Fidelis et al, 2018), biochar for leaf chlorophyll (Qian et al, 2019) and superabsorbent polymer for total dry matter (Yazdani et al, 2007) as compared with untreated plants.…”

E GYPT is currently experiencing water shortage, which causes a threat to crop productivity and efficiency of water use, especially in light of the current climatic changes. A field experiment was done to study effect of irrigation intervals (12, 16 and 20 days), soil amendments (compost, biochar, polyacrylamide "PAM" and hydrogel) beside control and their interaction on root, morpho-physiological, yield and quality traits of soybean.1-Prolonging irrigation intervals up to 20 days significantly decreased root characters (length and dry weight of root, number and dry weight of nodules/ plant and nitrogenase activity), morphological characters (plant height, leaves number/ plant, leaf area and total dry weight/ plant), physiological traits (relative water content and chlorophyll), yield (pods number/ plant, number and weight of seeds/ pod, 100-seed weight and seed yields/ plant and fed) and quality (protein% and oil and protein yields/fed).2-Application of soil amendments caused a significant and positive effect on root, morphophysiological characters as well as yield and seed quality compared to control. Hydrogel application produced the highest values of most abovementioned characters.3-The interaction revealed that highest values of most characters were obtained when plants were irrigated every 12 days and treated with hydrogel. Plants irrigated every 16 days produced the highest values of root length and oil yield when treated with PAM and hydrogel, respectively.4-Irrigation every 16 and 20 days can save water amounted to 18.62 and 27.82% compared to irrigation every 12 days, respectively. Irrigation every 16 days associated with hydrogel produced the highest values of water use efficiency (WUE) indicating that it was more effective for productivity and water consumption.

“…Hydrogel effects on productivity, phenology, root attributes and soil moisture dynamics. Hydrogels have been used as water-retaining polymers in agriculture 2,6,16,25−27 since they can retain a great amount of water when incorporated in soil and release it slowly more or less matching with plant requirement leading to improved crop growth and yield under water-stressed conditions 43 . In the current study, the applied hydrogels exhibited a signi cant effect on soybean and wheat growth, especially under limited irrigation and rainfed conditions.…”

“…A signi cant (P ≤ 0.05) enhancement in soybean seed yield (6-25%) and wheat grain yield (3-15%) in P-hydrogel applied plots compared to no-hydrogel (control) and K-hydrogel applied plots were observed (Table 3). All the other parameters being constant, the increase in yield may be attributed to the extended availability of water to plants in the polymer treatments during periods of water stress 10,11,43 . Similarly, Jarvis and Davies 44 reported that the increased photosynthesis rate and leaf relative water content in plants under superabsorbent polymers would enhance growth under drought-stress conditions.…”

Environmental crises, declining factor productivity, and shrinking natural resource threatened global agricultural sustainability. The task is much more daunting in the Indo-Gangetic northern plains of India, where depletion of the underground water table and erratic rains due to the changing climate pose a major challenge to agriculture. To address these challenges a field investigation was carried out during 2016–18 to test the efficacy of biopolymeric superabsorbent hydrogels namely Pusa Hydrogel (P-hydrogel: a semi-synthetic cellulose derivative-based product) and kaolin derivative of Pusa Hydrogel (K-hydrogel: semi-synthetic cellulose derivative) to assess their effect on crop and water productivity, soil moisture, root dynamics, and economics of soybean (Glycine max L.)–wheat (Triticum aestivum L.) system under three irrigation regimes namely full irrigation, limited irrigation and rainfed. The results revealed that the full irrigation along with P-hydrogel led to enhanced grain yield, biomass yield, and water productivity (WP) of soybean (1.61–10.5%, 2.2–9.5%, and 2.15–21.8%, respectively) and wheat (11.1–18.3%, 12–54% and 11.1–13.1%, respectively) over control plots. The best performance of P-hydrogel was observed under full irrigation compared to K-hydrogel (both at 2.5 and 5.0 kg− 1) and control. Plots treated with P-hydrogel retained 3.0–5.0% higher soil moisture compared to no-hydrogel plots, while K-hydrogel treated plots held the lower moisture (4.0–6.0%) than the control. In terms of profitability, full irrigation along with P-hydrogel plots registered 12.97% higher economic returns over control. The results suggested that full irrigation along with P hydrogels (2.5 kg ha− 1) is a viable option for sustainable production of soybean-wheat systems in the Indo-Gangetic plains of India and other similar eco-regions of the world.

“…For this study the soybean cultivar MonSoy 8644 was used with two sources of hydrogels and five concentrations of the products, in a total of totaling ten treatments. The experimental design was a randomized block design (DBC), with four replicates, in a 5x2 factorial scheme, with five product concentrations (0, 5, 10, 15 and 20 kg ha -1 ) and two hydrogel sources (Hydroplan and Polim-Agri), in the seedling line in soil during the planting, according to Lopes (2016) and Fidelis et al (2018).…”

The aim of this work was to verify the influence of hydrogel application during plant development on the biochemical composition of soybean grains. The experiment was carried out in a randomized complete block design with four replicates, in a 5x2 factorial scheme, with five concentrations (0, 5, 10, 15 and 20 kg ha -1 ) and two hydrogels sources (Hydroplan and Polim-Agri). The soybean cultivar used was MonSoy 8644.The biochemical contents evaluated were: oil, soluble carbohydrates, amino acids, starch, and proteins. The use of hydrogel was an alternative for grain production, since there no major changes in the contents of the biochemical compounds analyzed here. Highlighted Conclusions1) The use of hydrogel for the maintenance of soybean yield when cultivated in water deficit do not impaired the grain biochemical quality. 2) There is an interaction between carbohydrates and proteins levels, but not between oil and proteins in the treatment with hydrogel's doses.
