AB  - The aim of paper was to asses the use of regulated deficit irrigation (RDI) for production of two tomato cultivars (Cedrico and Abellus) in polytunnels in Serbia. RDI plants received 60% of the water that was applied to FI plants and significant saving of water for irrigation and increased in irrigation water use efficiency (IWUE) were achieved. Yield data for Cedrico cultivar showed no differences between RDI and FI, while due to the bigger sensitivity to drought, yield of Abellus was reduced under RDI. In general, fruit quality (soluble solids, titrable acidity) was sustained or improved in both cultivars under RDI. Economic analyses showed that due to the current low prices of water and electricity in Serbia, the profit increase of Cedrico, similarly to the previously trialed cultivar Amati, was not high under RDI comparing to FI. Reduction of yield and consequent profit for Abellus, indicated that for future commercial growing of tomato under RDI should be used drought resistant cultivars.

AB  - Many vegetables, including tomato and potato, have high water requirements, so that supplemental irrigation is necessary for successful production. The predictions are that the demand for irrigation will increase considerably in years to come to alleviate the consequences of climate change and more frequent and severe droughts. Water is expected to become the main limiting factor in agricultural production. However, as a consequence of global climate changes and environmental pollution, water available for agriculture is often reduced. Emphasis therefore must be placed on crop physiology and crop management under dry conditions in order to make plants more efficient water users. Recent results have demonstrated that regulated deficit irrigation (RDI) and alternate partial root drying (ARD) are new deficit irrigation strategies which may decrease demand for agricultural use of water. The application of these techniques to crops such as tomato and potato has demonstrated benefits in terms of improved wateruse efficiency and a stable yield, in addition to an increased yield quality. Both methods are developed on what is known on plant responses to drought stress and to the mechanism of root-to-shoot drought stress signalling. In this paper we review the research on the responses of tomato and potato to ARD and RDI irrigation strategies, with special emphasis on drought stress signalling mechanisms. Comparison of the beneficial effects of ARD and RDI were done with the aim to suggest which of these strategies may be used to get maximum tomato and potato water productivity and economic returns in dry environments.

AB  - The xylem hydraulic connection between shoot and fruits has previously been investigated, but contradictory conclusions were drawn about the presence of a flow resistance barrier in the pedicel. In this paper we were studying effect of the drought on the functional xylem vessels in the pedicels of tomato fruit. Commercial tomato genotype was grown in cabinet conditions under two watering regimes (full and deficit irrigation). An aqueous solution of eosin Y were used to visualize the path of water movement through tomato fruit pedicel and fluorescence microscopy observations were done on transversal and longitudinal sections. Dye uptake studies suggested that in well watered plants and in plants exposed to drought, a large majority of xylem vessels are not functional in water transport. Reduced-irrigation treatment significantly altered number and width of functional xylem elements in the fruit pedicel, especially in the abscission zone. This indicates that drought modifies xylem architecture and, thus, environmentally produced change in the hydraulic property of pedicel may affect fruit development.

AB  - Parameters of light interception have an important role in plant growth and dry matter production. Those parameters are: leaf area index (LAI), cumulative interception (CI), light interception (I) and light use efficiency (LUE). The aim of the presented research was to investigate the effect of nitrogen nutrition on light interception parameters and dry matter production and their relationships. A field experiment with leek was set up under nitrogen fertilization on a cambic soil. Nitrogen was incorporated in soil either as one-off or split dose and during experimental period light interception parameters were measured and calculated as well as dry matter production. The obtained results showed that light interception parameters and dry matter production increased over the vegetation period. Comparison of applied fertilizers methods showed that the split application technique had a better effect on light interception parameters, dry matter production and growth than the one-off dose. The split dose method also achieved better nitrogen utilisation over the vegetation period than the one-off dose.

AB  - Partial root drying (PRD) is a new irrigation and growing plants technique which improves the water use efficiency without significant yield reduction. The aim of the presented paper was to investigate the effect of PRD on tomato plant growth, water-use efficiency (WUE) and ions content and distribution in tomato organs. Obtained results showed that as a consequence of PRD treatment the growth of the whole plants was reduced, but not fruit, although WUE was increased. Water potential values of PRD plants did not differ significantly from those of well-watered plants. These results support the hypothesis that a root-sourced signal and not a leaf-sourced signal may be responsible for triggering growth reduction in these PRD plants. Data for ions content (N, P, Ca, Mn, Zn and Cu) and their distribution between roots, shoots and fruits showed that PRD treatment only significantly changed N content in the shoots.
