“…On average, the highest B-WUE was achieved with treatment DK (22.48 kg m 3 ). Boari et al (2015) and Lukic et al (2012) arrived at similar conclusions, that deficit irrigation with kaolin increased both YWUE and B-WUE. The average values of B-WUE varied from 17.7 for FC to 23.16 kg m 3 for FK, which is consistent with the results reported from Spain (Battilani, 2006).…”

a b s t r a c tModern agriculture is faced with two tasks: (1) to produce enough food for a growing global population, and (2) to ensure satisfactory crop quality while using water resources efficiently. A study of the effect of kaolin on the yield, quality and water use efficiency of tomato (Lycopersicon esculentum Mill.), grown under different irrigation regimes, is reported in the paper. The research was conducted in an open field with carbonate chernozem soil, at Stara Pazova (40 km north of Belgrade, Serbia). It lasted for three years (2011, 2012, and 2013). The experimental setup was a two-factorial, completely random block system, with three replications. The first factor was the irrigation regime and the second the application of kaolin. Two irrigation treatments were studied: (a) full irrigation (F), covering 100% of ETc (crop evapotranspiration), and (b) deficit irrigation (D) at 50% of ETc. The kaolin treatments were: (a) control treatment, without kaolin (C) and treatment with a 5% suspension of kaolin (K).On average, the highest fresh tomato fruit yields were achieved under full irrigation, with kaolin (FK) (21.0 kg m −2 ). The FK treatment also resulted in the greatest dry weight of the fruits (1.1 kg m −2 ). The average fruit weight was rather uniform and ranged from 71.7 g with DC to 75.4 g with DK. The average sugar and lycopene content was quite uniform over the study period, while the irrigation regime had a significant effect on the average organic acid content and total antioxidant activity. Deficit irrigation treatments resulted in a higher organic acid content and higher total antioxidant activity than full irrigation. The application of kaolin had a greater effect of the water use efficiency of tomato than the irrigation treatment.

“…Similar results have been reported by other (Della Costa and Gianquinto, 2002;Dagdelen et al, 2004;Sezen et al, 2006;Karam et al, 2009), who claim that mild deficit irrigation increases the water use efficiency of peppers and that the time of application (phenophase) is very significant, as the pepper is the most sensitive in the flowering and yielding stages. Kaolin application did not affect yWUE and bWUE of the sweet pepper, contrary to reports by Lukic et al (2012) for tomato and Boari et al (2015) for different crops on a photosynthesis, biomass or yield scale.…”

“…It is also possible that the amount applied (26 mL per plant) was too small to result in a significant proportion of whiteness and reduce leaf temperature, so that it is not recommended in the case of peppers grown in the spring. As such, for kaolin to reduce sunburn, mitigate heat stress and water stress, and ensure pest control, adequate concentrations need to be applied, as shown in the present research and research reported by others (Melgarejo et al, 2004;Cantore et al, 2009;Boari et al, 2015).…”

“…Their results indicate that kaolin exhibited the greatest effect by reducing stomatal conductance, which contributed to decreased transpiration, improved plant water status and lower net assimilation. In addition to performing well in pest control and heat stress mitigation, kaolin can effectively be used as an antitranspirant to reduce the effect of heat stress and salinity, and to save water (Boari et al, 2015). The application of kaolin reduced the temperature of citrus fruits by 1-6 • C, on average, which resulted in less sunburn and better crop quality (Miranda et al, 2007).…”

“…This is a very difficult task, given the length of these phenophases of most pepper cultivars (GonzalezDugo et al, 2007). Apart from DI, the application of kaolin could be one of the options for mitigating drought impact and saving water in agriculture (Boari et al, 2015). The use of kaolin creates a canopy cover (over the above-ground part of the plant and fruits), which reduces the water loss by transpiration.…”
