“…Literature data indicated that ABA-deficient tomato mutants notabilis and flacca produce 1.6-2.3-fold more ethylene than wild types (Hussain et al 2000). In our experiment, the average concentration of ABA in the flacca fruits was 49% of the concentration of ABA measured in the wild type fruits of Ailsa Craig (Marjanović et al 2015). Although we did not measure the ethylene levels in the fruit, it could be assumed that the antagonistic interaction levels between ABA and ethylene could also explain the size of the flacca fruits in our experiment, which was significantly lower than in wild type Ailsa Craig.…”

“…Our results related to the fruit growth rate and ABA concentration in this phase are in agreement. The investigation of ABA content in the tomato pericarp of Ailsa Craig grown under different irrigation treatments also showed a declining trend during the tomato development until the end of the cell growth phase without any significant differences between differently treated plants (Marjanović et al 2015).…”

“…The results of Savić et al (2008) indicated that cell wall peroxidase activity increases during the deceleration of tomato fruit growth and during maturation. Also, the study of the effects of PRD on tomato fruit growth in cultivar Ailsa Craig showed that the increase in the activity of cell wall-associated peroxidase in the tomato fruit pericarp coincided with the end of cell growth and the beginning of the ripening process thus indicating that this enzyme may regulate tomato fruit maturation (Marjanović et al 2015).…”

To assess the effects of ABA deficiency on tomato fruit growth, the ABA mutant flacca was grown in an optimal soil water regime and various analyzes were performed, including morphological (fruit number, diameter and fruit biomass), physiological (duration of growth and fruit growth rate), biochemical (ABA accumulation, enzyme cell wall peroxidase activity) as well as proteomics. The fruit growth analysis showed that the slower fruit growth rate and development resulted in smaller flacca fruits in comparison to the wild-type fruits. The comparison of the temporal dynamics of cell wall peroxidase activity and ABA content in our experiment indicated an opposite relationship during fruit development. Proteomic analysis and the down-regulation of most proteins from carbon and amino acid metabolism, the translation and processing of proteins, energy metabolism and cell wall-related metabolism in the flacca fruits compared to the wild type, indicated reduced metabolic flux which reflected a slower fruit growth and development and reduced fruit size in the ABA mutant. These findings also indicated that ABA limited carbon sources, which could be responsible for the reduced fruit growth and size of ABA-deficient tomato fruits. The up-regulation of sulfur and oxygen-evolving enhancer proteins in the flacca fruits implicated the maintenance of photosynthesis in the late expansion phase, which slows down transition to the ripening stage. The majority of antioxidative and stress defence proteins were down-regulated in the flacca fruits, which could be related to the role of ABA in the activity of different antioxidative enzymes as well as in regulating cell wall expansion and the cessation of fruit growth.

“…Basically, well watered side of the soil maintains a well plant status while dehydration of the other side encourages the synthesis of the abscisic acid and therefore decrease stomata conductance (Giuliani et al, 2017). Among various irrigation techniques PRD has the potential of increasing water use efficiency and sustain yield of different crops (Hu et al, 2009;Nardella et al, 2012;Yactayo et al, 2013;Marjanovic et al, 2015;Wei et al 2016and Gomaa et al, 2018Qi et al, 2019. DI irrigation has been shown as an effective irrigation strategy to save water while maintaining yield reductions at the minimum and increase WUE (Nangare et al, 2016 andMele 2019).…”

The availability of fresh water and energy resources in remote locations is a major challenge for agricultural crop production in many countries in the Middle East region. Using limited water resources efficiently is crucial to sustain rapidly population growth. This research aimed to investigate the possibility of enhancing productivity and water productivity of squash crop through deficit irrigation technique. Two field studies were carried out to investigate the response of squash crop to deficit irrigation (DI) technique and potassium fertilization (K) over the spring and fall seasons of 2018. The irrigation treatments were based on the reference evapotranspiration (ETo). The results showed that the optimum squash seed yield could be obtained with K fertilizer level of 250 kg K 2 O ha -1 and irrigation with amount of water equals 75% of ETo using DI with laterals placed at 0.15m from crop row or 50% of ETo in the last stage using RDI techniques. Fully irrigated (1.0 ETo) treatments had the highest values of yield and yield components of squash and there were no significant differences with RDI and DI with 0.75 ETo. The application of RDI can save more than 20% of applied water with no significant reductions in squash yield. Potassium rates enhanced squash yield and water productivity with the greatest value at 250 kg K 2 O 5 ha -1 .

Wastewater use in agricultural irrigation is becoming a common practice in order to meet the rising water demands in arid and semi-arid regions. The study was conducted to determine the effects of the full (FI), deficit (DI), and partial root-zone drying (PRD) irrigation practices using treated municipal wastewater (TWW) and freshwater (FW) on tomato yield, water use, fruit quality, and soil and fruit heavy metal concentrations. The TWW significantly increased marketable yield compared to the FW, as well as decreased water consumption. Therefore, water use efficiency (WUE) in the TWW was significantly higher than in the FW. Although the DI and the PRD practices caused less yields, these practices significantly increased WUE values due to less irrigation water applied. The water-yield linear relationships were statistically significant. TWW significantly increased titratable acidity and vitamin C contents. Reduced irrigation provided significantly lower titratable acidity, vitamin C, and lycopene contents. TWW increased the surface soil and fruit mineral contents in response to FW. Greater increases were observed under FI, and mineral contents declined with reduction in irrigation water. Heavy metal accumulation in soils was within safe limits. However, Cd and Pb contents in fruits exceeded standard limits given by FAO/WHO. Higher metal pollution index values determined for fruits also indicated that TWW application, especially under FI, might cause health risks in long term.
