“…The superiority of the highest level of the hydrogel composite might be referred to regulates nutrients absorb by plant, availability enough water for longtime than control. Such results are in harmony with on Citrus limon and on Grandnain Banana Plants, who found that, increasing the amount of hydrogel increased flower number per shoot, fruit setting and yield (Kg /tree) [21][22]. Among all the treatments, T4 was found to be the best with respect to yield (113.67 and 118.33 kg/tree) which was significantly higher than other treatments; while T2 recorded lower yield (91.67 and 59 kg/tree) comparing other hydrogel treatment in both seasons, but still higher than control treatment which recorded the lesser values (76.00 and 78.33 kg/tree) in both experiment seasons , this may be due to increasing water availability and the soil was wet for a longer time, so, increasing the availability of nutrients, and also helps in reducing the fruit drop due to water stress, this agrees with the study by for the increased yield of citrus reticulata by the application of hydrogel [21].…”

This investigation was carried out at a private orchard, in Nubaria district, Behera Governorate, on “Washington Navel orange” trees [Citrus sinensis L.(Osbeck)] during the grown seasons of 2016 and 2017. The experimental site represents newly reclaimed sandy soil irrigated through drip irrigation system. This work aims to study the impact of hydrogel composite as substance holding water in the soil on improvement total yield, and fruit characters of W Navel orange tree. The treatments were applied as soil application at zero, 500, 1000 and 1500 g hydrogel composite/tree. The obtained results cleared that medium or high dose of hydrogel composite (1000 or 1500g/tree) enhanced the most studied parameters, it increased total yield, fruit weight, and enhancement fruit quality, different treatments of hydrogel composite increased fruit content of total soluble solids and total sugars. However, 1500g/tree treatment was the best treatment and recorded highest total yield. This may be due to the vital role of hydrogel composite in increasing water availability and nutrients for the tree for a longtime as well as increasing the fruit retained. Moreover, with respect to tree growth, it was found that there was a significant increase in the vegetative growth parameters (shoot length, leaf area, and tree canopy) in all the treatments where hydrogel composite used as compared to untreated tree.

“…Hassan and Ali [35] and Silber et al [36] suggested, however, that reduced photosynthesis during drought can be due to nutrient deficiency rather than lack of water. In either case, hydrogels can absorb either water or nutrients from the soil [37] and gradually release them to the soil in the root zone during drought conditions [38]. The absorption and rerelease of nutrients by the hydrogel can maintain photosynthetic rates [39].…”

The effect of soil amendment with hydrogel on reducing water stress was tested for Siberian elm (Ulmus pumila) and silver maple (Acer saccharinum) saplings. The trees were planted in soils with one of two concentrations of hydrogel (0.5% or 1% dry weight) as compared to the control soil (0% of hydrogel) and watered either daily, weekly, or bi-weekly. Growth was monitored by measuring height and stem diameter. Stress was monitored by measuring SPAD readings and normalized difference vegetation index (NDVI), as proxy measures of chlorophyll content and photosynthetic activity, respectively. Water stress decreased NDVI (p < 0.05) but did not have a significant effect on SPAD readings. Soil with 0.5% concentration of hydrogel was positively associated with greater height and NDVI (p < 0.01) for both maple and elm trees. Hydrogels had a species-specific effect on SPAD readings. The interaction between hydrogel concentration and the watering regime had a significant effect on the height and NDVI (p < 0.01) of elms, but not maples. The improved performance of water-stressed tree saplings in hydrogel-amended soils was presumably due to the ability of hydrogels to absorb and then gradually release water and nutrients. This is of special interest for urban foresters, because water stress and nutrient deficiency are two important growthlimiting factors for street trees.

An experiment was conducted to find out the effect of drip trickle irrigation and hydrogel with black polyethylene mulch on productivity and water use efficiency of Kinnow mandarin. The two years pooled data revealed that highest available nitrogen, phosphorus and potassium (244, 20 and 164 kgha-1), porosity and maximum water holding capacity (34.5 and 40.9 %) and percent increase height, spread and canopy volume (13.6, 14.8 and 44.5 %), respectively, were obtained with the application of 3 days drip trickle irrigation and 90 g hydrogel with black polyethylene mulch materials of tree. The drip trickle irrigation and hydrogel with black polyethylene mulch produced a significantly (p=0.05) maximum improve in soil moisture content over control treatment. The 3 days drip trickle irrigation and 90 g hydrogel with mulch showed highest fruit yield (9404.7 kg ha-1), length (6.5 cm), weight (116.5 g) and quality of fruit volume (113.9 cc), Juice content (54.1 %) and TSS (13.3 0Brix). The specific gravity and titratable acidity showed reverse trend. The water use efficiency and benefit cost ratio were better in 3 days drip trickle irrigation and 90 g hydrogel with mulch materials of tree.
