AB  - Consumption of fresh vegetables and fruits is a healthy diet supply and it is recommended as prevention of illnesses. There is an increasing trend in consumption of fresh vegetables and fruits in the world, and their microbiological quality is very important for public human health and protection. Contamination of vegetables and fruits is the result of presence of human pathogen bacteria which can contaminate products in any part of production chain. There is an evidence of presence of: Salmonella spp., Escherichia coli, E. coli O157:H7, L. monocytogenes on the fresh vegetables. Salmonellosis is connected with tomato, sprouts, cantaloupe etc. E. coli and E. coli O157:H infections are linked with lettuce, sprouts, carrot etc. There has been an increasing number of outbreaks caused by human pathogen on fresh vegetables and fruits in the recent years. Contaminated irrigation water is a very effective vector of the transmission of human pathogen to plants, so microbiological safe water has special importance in health safety food production. Contamination of fresh vegetables by human pathogen bacteria depends on bacterial ability to colonize plant. In the case of microbiological contamination of fresh vegetables and fruits, it is very difficult to carry out decontamination of product, because it is impossible to remove all attached bacteria only by washing. The goal of this research is an investigation of presence and identification of pathogen bacteria in the irrigation water and on vegetables, transmission of pathogen bacteria from irrigation water to plants and studying/monitoring the ability of the human pathogen to colonize the surface and endophyte of root, stem and leaf of different vegetable species. Microbiological quality of water and vegetables is estimated on the basis of the presence and number of coliform bacteria, as well as certain species of pathogen bacteria. Isolated strains of human pathogen bacteria are identified by their morphological, ecological and biochemical properties. Transmission of pathogen bacteria from irrigation water to plants, as well as colonization of plants by human pathogen bacteria was investigated by: applying PCR method, using green fluorescent protein transformed bacteria, fluorescence in situ hybridization (FISH) and confocal laser scanning microscopy (CLSM)...

AB  - Partial root-zone drying (PRD) is a new water-saving irrigation strategy which requires that the roots are simultaneously exposed to both dry and wet soil zones. This technique is now undergoing extensive trials with a range of agricultural crops. These results show significant benefit in increasing water-use efficiency. The field potato (Solanum tuberosum L cv Liseta) experiments were conducted during 2007 and 2008. Subsurface drip irrigation was used. In 2007 season PRO plants received 70% of full irrigation (FI). To further enhance water saving during the last 3 weeks of the irrigation period, PRO using 70% of FI was replaced with PRD using 50% of FI in 2008. By five harvests during the season N content, fresh and dry matter (DM) of leaves, stems and tubers were followed. At final harvest the effects of PRD and FI irrigation on total and marketable yield and yield quality were investigated. Also, the irrigation water-use efficiency (IWUE) was calculated. As compared to FI, PRO treatment saved 33% (2007) and 42% (2008) of irrigation water while maintaining similar yield. This resulted in 38% and 61% increase in IWUE for the 2007 and 2008 seasons, respectively. In both years the PRO treatments resulted in the increase of N, starch content and antioxidant activity in potato tubers. The latter novel findings on the effect of PRD irrigation on tubers quality might be favorable for the health-promoting potato value.

AB  - Drip irrigation systems and irrigation strategies like deficit irrigation (DI) and partial root drying (PRO) are potential water saving irrigation systems and strategies. This paper analyses the Serbian farmer's economic incentive to use these water saving systems and strategies instead of the present sprinkler irrigation. The analysis is a partial budgeting analysis, based on irrigation application efficiency from the literature, standard figures for power requirements, pumping efficiency and friction losses for various sources of water and pressure requirements, yields and water use from recent Serbian field experiments, as well as prices and cost structures for potatoes collected in the Belgrade region. The analysis shows that changing the present system and strategy can save a significant amount of water (almost 50%). At the same time, however, irrigation costs are also significantly increased (more than doubled), and the total production costs are increased by 10% (deficit drip irrigation) and 23% (PRD). Increased taxes on water, investment subsidies, increased energy prices, and an increased yield or yield quality may provide incentives for farmers to change to new systems and strategies. The analysis indicates that a 0.80 to 1.97(sic) m(-3) water tax is needed to make deficit drip irrigation and PRD profitable. The socioeconomic cost of providing water for irrigation and the alternative value of saved water are probably not that high. Thus, water taxation may not be a socioeconomic efficient means to improve the irrigation water productivity of Serbian potato production. Drip irrigation and PRD may, however, also increase the yield quality, and a 10-23% quality premium (price increase) is needed to make deficit drip irrigation and PRD profitable.

AB  - Water availability for irrigation is a limiting factor for agriculture in Mediterranean countries. An upcoming strategy for increasing water supply is to use treated wastewater for irrigation. A principal drawback of irrigating with wastewater is the potential heavy metal accumulation in soil and foodstuff. Accumulation of heavy metals in soil and potato plants (Solanum tuberosum L) irrigated with treated low quality surface water was studied in a three years experiment. The low quality surface water used for irrigation experiments contained a significant proportion of urban sewage and was spiked with selected heavy metals (Cd, Cr, Cu, Pb) and arsenic before treatment for years 2 and 3. The experiments were carried out during the growing seasons of 2006, 2007 and 2008 on a humogley soil of a commercial vegetable farm, 10 km north of Belgrade, Serbia. The growing seasons started in April/May and finished in August. Irrigation water was treated using (1) a conventional sand filter treatment, and (2) a sand filter combined with a specific filter for heavy metal removal treatment. Irrigation water composition was highly variable and cases both of enrichment and depletion of the measured inorganic trace elements were observed in the treated water, compared to the low quality feed water. In spite of this variability of the irrigation water composition, the soil contents in inorganic elements at the end of the three irrigation years are similar to the initial state. After the third harvest, no impact of the irrigation water on potato quality could be detected except for total sugar and sugar in total solids. Statistical tests (ANOVA) were performed to assess similarities between the different set of samples. The principal conclusion of this investigation is that, when appropriately treated, low quality feed waters with high heavy metal contents can be used for irrigation over several years without significant degradation of soil and produces. Even though, long-term cumulative effects in other pedologic and hydroclimatic settings, irrigation and cropping conditions cannot be excluded.

AB  - Clean water has become one of the main limiting factors in agricultural food production in Europe, especially for countries around the Mediterranean, who now face more severe and-frequent seasonal water shortages. In order to overcome water shortages the European Water Framework Directive encourages and promotes the use of treated urban wastewater in agriculture. However, the use of poor quality water in agriculture poses potential health risks. The application of wastewater through subsurface drip irrigation lines could possibly overcome public health concerns by minimizing contact with wastewater by farmers, farm workers but it is uncertain if the risk for consumers of wastewater irrigated produces would be acceptable. The objective of the current study was therefore to assess whether subsurface irrigation of potatoes with low quality water was associated with higher food safety and reduced human health risks as compared with surface irrigation. The microbial quality of soil and potatoes irrigated by sprinkler, furrow and subsurface drip irrigation, using treated urban wastewater, canal water and tap water were compared at experimental sites near Belgrade, Serbia and in Bologna, Italy. Water, soil and potato samples were collected from March 2007 to September 2008 and their faecal contamination estimated by enumeration of the faecal indicator Escherichia coli. In addition, water and potatoes in Italy were analysed for the presence of helminth eggs, another important indicator of faecal pollution. A quantitative microbial risk assessment (QMRA) model combined with Monte Carlo simulations was used to assess whether the different irrigation practices and associated health risks complied with guidelines set by the World Health Organization (WHO). The study found low levels of E. coli in irrigation water (Italy mean value: 1.7 colony forming units (cfu)/ml and Serbia 11 cfu/ml), as well as in soil (Italy mean: 1.0 cfu/g and Serbia 1.1 cfu/g). Similar low concentrations of E. call were found on potatoes (Italy mean: 1.0 cfu/g and Serbia 0.0 cfu/g). The vast majority (442/516) of the collected different samples were free of E. coli. No helminth eggs were found in any types of irrigation water or on the surface of potatoes. The risk assessment models found the use of treated wastewater to exceed the levels of risks for gastro-intestinal disease (1.0 x 10(-3) disease risk) as recommended by the World Health Organization (WHO) for the accidental ingestion of soil by farmers (Serbia: 0.22 and Italy: 5.7 x 10(-2)). However, samples that exceeded disease risks set by the WHO were collected before initiation of wastewater irrigation and were limited to a few numbers of samples, which would indicate environmental contamination not linked to irrigation practice. Disease risk from consumption of potatoes in Italy and in Serbia was found to be within acceptable levels. No relationship was found between E. coli concentrations in irrigation water, soil and produce. Similar lack of association was found for E. coli findings in sprinkler, furrow or subsurface drip irrigated soils and produce. This indicates that subsurface drip irrigation can be practiced while ensuring food safety and protecting the health of consumers and farmers.

abstract = "Clean water has become one of the main limiting factors in agricultural food production in Europe, especially for countries around the Mediterranean, who now face more severe and-frequent seasonal water shortages. In order to overcome water shortages the European Water Framework Directive encourages and promotes the use of treated urban wastewater in agriculture. However, the use of poor quality water in agriculture poses potential health risks. The application of wastewater through subsurface drip irrigation lines could possibly overcome public health concerns by minimizing contact with wastewater by farmers, farm workers but it is uncertain if the risk for consumers of wastewater irrigated produces would be acceptable. The objective of the current study was therefore to assess whether subsurface irrigation of potatoes with low quality water was associated with higher food safety and reduced human health risks as compared with surface irrigation. The microbial quality of soil and potatoes irrigated by sprinkler, furrow and subsurface drip irrigation, using treated urban wastewater, canal water and tap water were compared at experimental sites near Belgrade, Serbia and in Bologna, Italy. Water, soil and potato samples were collected from March 2007 to September 2008 and their faecal contamination estimated by enumeration of the faecal indicator Escherichia coli. In addition, water and potatoes in Italy were analysed for the presence of helminth eggs, another important indicator of faecal pollution. A quantitative microbial risk assessment (QMRA) model combined with Monte Carlo simulations was used to assess whether the different irrigation practices and associated health risks complied with guidelines set by the World Health Organization (WHO). The study found low levels of E. coli in irrigation water (Italy mean value: 1.7 colony forming units (cfu)/ml and Serbia 11 cfu/ml), as well as in soil (Italy mean: 1.0 cfu/g and Serbia 1.1 cfu/g). Similar low concentrations of E. call were found on potatoes (Italy mean: 1.0 cfu/g and Serbia 0.0 cfu/g). The vast majority (442/516) of the collected different samples were free of E. coli. No helminth eggs were found in any types of irrigation water or on the surface of potatoes. The risk assessment models found the use of treated wastewater to exceed the levels of risks for gastro-intestinal disease (1.0 x 10(-3) disease risk) as recommended by the World Health Organization (WHO) for the accidental ingestion of soil by farmers (Serbia: 0.22 and Italy: 5.7 x 10(-2)).

AB  - The effects of partial rootzone drying (PRD), deficit irrigation (DI), and full irrigation (FI) on tomato physiology were investigated. In PRD and DI plants, leaf water potential values and stomatal conductance were significantly lower, while xylem ABA concentration was greater compared to FI plants. Photosynthesis was similar for all treatments. Water use efficiency was improved by PRD and DI, which reduced fruit dry weight, but had no effect on dry weight of leaves and stems.

AB  - Partial rootzone drying (PRD) is a new water-saving irrigation strategy that requires that the roots are simultaneously exposed to both dry and wet soil zones. This technique is now undergoing extensive trials with a range of agricultural crops and these results showed significant benefit in increasing water use efficiency. The field potato (Solanum tuberosum L., cv Liseta) experiment was conducted during 2006. Subsurface drip irrigation was used. In the season PRD plants received 70% of fully irrigated (Fl). Plant growth and biomass production were followed in the tuber bulking phase. At a final harvest, the effects of PRD and Fl irrigation on total and marketable yield were investigated and irrigation water use efficiency was calculated (IWUE). In comparison to Fl, PRD treatment saved 26% of irrigation water, while maintaining similar yield resulting in 24% increase in IWUE. .

AB  - Predmet ovog istrazivanja je ispitivanje efekata delimičnog sušenja korenova (DSK) na kva­litet tri značajne poljoprivredne kulture - paradajza, krompira i vinove loze, a posebno na anti­oksidativnu aktivnost. U oba eksperimentalna sistema (plastenik i polje) sadržaj vode u zemlji­štu u uslovima optimalnog navodnjavanja (FI) održavan je blizu vrednosti poljskog vodnog ka­paciteta, dok je kod DSK tretmana, jedna polovina korenovog sistema zalivana 60% od FI, a za­mena strana zalivanja je izvršena u skladu sa smanjenjem sadržaja vode na strani korena koja ni­je prethodno zalivana. Na kraju vegetacione sezone urađena je analiza prinosa i kvaliteta plodo­va i krtola, kao i efikasnost usvajanja vode (WUE). Generalno, u ogledima nisu utvrđene značaj­ne razlike u prinosu, dok je WUE i antioksidativna aktivnost bila veća nego kod optimalno na­vodnjavanih biljaka. Dobijeni rezultati ukazuju da delimično sušenje korenova (DSK) može bi­ti korisna strategija u očuvanju vode za navodnjavanje koja neće dovesti do značajnih redukcija kvantiteta iii kvaliteta prinosa.
