AB  - The aim of this study was to evaluate the thinning efficacy of metamitron applied either alone (single or double application) or in combination with 6-benzyladenine (BA) or naphthalene acetic acid (NAA) in young 'Gala' and 'Golden Delicious' apple trees. The experiment was carried out during the first three crop seasons, 2014, 2015, and 2016, at the commercial orchard located on the mountain Fruska Gora, Serbia. Application of chemical thinners was carried out at two fruit diameter stages (6-9 and 12-15 mm). The number of fruit and yield per tree, fruit size distribution, parameters of fruit ripeness, and return bloom were assessed. Single metamitron treatments were effective when the weather conditions were favourable on the day of application and 3 days after (minimum night temperature >10 degrees C, maximum daily temperature >20 degrees C) regardless of fruit diameter stages. A reduction in fruit number per tree was followed by an increase in mean fruit weight. Double metamitron application at lower concentration caused relatively stable thinning activity during the whole experimental period in both cultivars tested. Metamitron combined with either BA or NAA at standard rates significantly reduced the negative influence of low temperature on metamitron thinning activity in the first experimental year. These treatments slightly influenced overthinning in 'Gala' trees if applied when the air temperature was too high minimum night temperature >15 degrees C, maximum daily temperature >25 degrees C). Repeated metamitron treatment and treatments in which metamitron was combined with BA and NAA resulted in an increase in fruit size and share of large fruit in the total yield during the whole experimental period in both cultivars tested. A reduction in fruit number per tree affected by these treatments was followed by increasing flowering intensity in the subsequent year, with the exception of double metamitron application to 'Golden Delicious' trees in the last experimental year. Fruit maturity parameters were slightly different under the influence of metamitron treatments.

AB  - The effect of different irrigation regimes and the application of kaolin on the canopy temperatures of sweet pepper (Capsicum annuum L.) and tomato (Lycopersicon esculentwn MilL), determined by a nondestructive imaging method, is discussed in the paper. The research was conducted in an open field on carbonate chernozem soil at Stara Pazova (40 km north of Belgrade, Serbia), over a period of three years (2011, 2012 and 2013). The 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. The experimental pepper plants were subjected to thre different irrigation regimes: a) full irrigation (F), covering 100% of ETc (cultivar's evapotranspiration rate); b) deficit irrigation at 80% of ETc (R1); and deficit irrigation at 70% of ETc (R2). Two different irrigation regimes were monitored in the case of tomato: full irrigation (F), covering 100% of ETc, and b) deficit irrigation at 50% of ETc (D). The kaolin treatments of both crops were: a) control without kaolin (C) and 5% kaolin suspension (K). The results of this research indicated that the irrigation regime had a very significant effect on the temperature of pepper and tomato; the higher the level of irrigation, the lower the temperature. The dual-effect of kaolin impacted the heat balance of the plants.

AB  - The applicability of the FAO AquaCrop model to simulate sweet pepper growth with and without plastic film mulching under different water supply and weather conditions is assessed. Pepper yield and biomass are simulated using the results of a two-year (2012 and 2013) field experiment conducted in Stara Pazova and a three-year (2011, 2012 and 2013) field experiment in Sombor, both in Serbia. The year 2012 was much warmer and drier than the two other years. At the Stara Pazova site, black plastic mulch was used and three different irrigation treatments applied: 1) full irrigation (F), at 100% of ETc (crop evapotranspiration); 2) deficit irrigation (R), at 80% of ETc; and 3) deficit irrigation (S), at 70% of ETc. In Sombor, only full irrigation (F*) was applied and there was no mulching. Two different cultivars (cv. Elephant Ear and Misina) were grown in Stara Pazova and Sombor, respectively. The model was calibrated using data from the F-treatment in 2012 at Stara Pazova and F*-treatment in 2011 at Sombor, given that the highest yields were recorded in these two cases. The difference between the measured and simulated values was 2.9% and 7.5% for yield and 7.6% and -14.3% for biomass, in Stara Pazova and Sombor, respectively. The calibration results showed a very good agreement between the measured and simulated values. The deviation of simulated yields from the measured values in the validation data set depended on weather and soil conditions. Namely, the match was very good in the case of well-watered pepper grown without plastic film mulching in the average year at Sombor (1.2%), and was the worst in the extremely warm year (-45.2%). Similar differences were noted in biomass. Based on statistical indicators, the coefficient of determination (R-2) of pepper yield at Stara Pazova and Sombor was 0.61 and 1.00 and the Willmott index of agreement (d), 0.79 and 0.89, respectively. Thus the AquaCrop model simulates the yield of pepper grown with and without plastic film mulching quite well. Biomass simulations resulted in slightly lower values of R2 and d. The AquaCrop model can also predict the amount of water needed for pepper grown with and without black plastic mulch.
