“…In line with previous studies [52][53][54][55][56] drought treatments (I80 and I60) reduced lettuce head weight (HW) as well as growth parameters (PH, PD, RL, RD, RW, and SD), regardless of the lettuce genotype and growing cycles. On average across treatments, the highest stability was shown by the butterhead genotype (G-BL) with the highest HW in both growing cycles.…”

“…Studies on the negative impact of drought stress on lettuce yield and quality are well documented, it is also well acknowledged that the lettuce's highest yield, leaf number, plant weight, height and diameter, root weight, length, and diameter were obtained on no stressed treatments, that is on treatment with the highest irrigation rate [52][53][54][55][56]. The beneficial effects of mycorrhizae on the growth-related traits and nutritional quality of lettuce plants were previously reported by many authors as well [57][58][59][60][61].…”

Morphological and biochemical responses were assessed in an iceberg (GIL) and butterhead (GBL) lettuce (Lactuca sativa var. capitata) treated with commercially available soluble preparation of mycorrhizal fungi and beneficial soil bacteria (MT) grown in three irrigation treatments considered in greenhouse (continental Croatia, 2022): I100—control treatment (100% volumetric water content—VWC); I80—80% VWC, moderate drought and I60—60% VWC, severe drought), in two growing cycles. MT was applied during lettuce drought-sensitive stages, i.e., transplanting and heading. Study results show that MT improved lettuce growth-related traits, yet the results are genotype and growing-cycle dependent. The beneficial effect of MT was also noted for root length, weight, and diameter which confirms the mycorrhizal role in improving the plant water uptake. Both lettuce genotypes responded to water deficit by overproduction of MDA and proline content, whereby the response of tested variables was growing cycle and genotype-specific. Both genotypes in severe drought treatment (MT-I60) responded with higher MDA in the first growing cycle and lower MDA content in the second growing cycle. MT-I60 treatment reduced proline accumulation in GBH in both growing cycles, while increased accumulation in GIL during the second growing cycle. The responses of lettuce to MT are genotype-specific and shaped by environmental conditions.

“…These results are consistent with Kurunc 30 and Ibrahim et al 31 who stated that water stress in lettuce is often accompanied by significant yield reductions and poor marketing quality. The sensitivity of lettuce to water stress may be attributed to its shallow root system that limits its ability to absorb water from deeper soil layers under water deficit conditions 21 , 32 , 33 . However, the application of super absorbent hydrogels mitigated these negative effects in water-stressed plants.…”

Due to water scarcity challenges, efficient management of irrigation water is becoming crucial. Water use efficiency (WUE) involves increasing crop productivity without increasing water consumption. This study was carried out to study the effect of hydrogel, deficit irrigation and soil type on WUE, soil hydro-physical properties and lettuce productivity. For this purpose, four irrigation treatments (100%, 85%, 70% and 60% of full irrigation requirements), four hydrogel concentrations (0, 0.1, 0.2 and 0.3% w/w) and three soil textural classes (clay, loamy sand, and sandy-clay soil) were conducted in pot experiment at open field during two consecutive seasons. The results revealed that crop growth parameters and soil hydro-physical properties were significantly affected by hydrogel application rates. Hydrogel addition significantly enhanced head fresh and dry weights, chlorophyll content, number of leaves and WUE. Application of hydrogel at 0.3% and 85% of irrigation requirements achieved the highest WUE without significant yield reductions. Changes in the studied hydro-physical properties of soil were more dependent on soil texture and hydrogel application rate than on the amount of irrigation water. The significant decrease in soil saturated hydraulic conductivity and bulk density confirms that super absorbent hydrogels could be recommended to improve soil water retention and enhance water use efficiency under deficit irrigation conditions.
