Selection of tomato lines for industrial use regarding their nutritional value is a potential that will reflect in the final product obtained from tomato fruits. At the same time, technological process of preparation of tomato juice (100 °C), as well as hot air drying, was studied in order to establish an optimal technological process that is the least disrupting for the natural potential of nutrients contained in fresh fruits. The research was performed on 6 lines and one variety of industrial tomato. The content of vitamin C, vitamin E, lycopene, β-carotene, phenols, flavonoids, dry matter and total antioxidative capacity was studied by applying standard methods for determination of the level of these parameters. Grouping was performed according to traits of average carotenoid content (lycopene, β-carotene), vitamin C, vitamin E, phenols, flavonoids, dry matter and total antioxidative capacity in tomato fruit, by applying PCA. The first two principle components were responsible for 77.18 % of total variability of researched samples. The impact of other five components was low and they were responsible for 22.18 % of the variability. Antioxidative activity was best preserved after finishing, through small losses of lycopene and β-carotene. Losses of vitamin C, vitamin E, phenols and flavonoids during thermal processing were great, mostly in juice, while in dried product, these losses were lower. Nutrient losses were in function of temperature height that the fruits were exposed to during the thermal processing. Genotypes SPRZ and SPSM were marked as the best.

Weather derivatives are contemporary instruments for insurance risk of drought in agricultural production. Corn production is particularly sensitive to this risk, and the amount of the yield of this crop is in significant correlation with the July-August rainfall amount. Oscillations of production output, caused by the risk of drought, are reflected directly on the fluctuations of the financial result. The application of weather derivatives may decrease the variability of the mentioned economic parameter in corn production. In the investigated example of corn production, simulating the application of the weather option the coefficient of variation of realized financial results decreased by 9.64% compared to the version without the insured risk. At the same time, using the analysed insurance instrument, the risk of achieving a negative financial result is eliminated.

Summary: Our paper provides new data on genetic control of flower number per axillary inflorescence in garden pea ( Pisum sativum L.). This trait is of both agricultural and evolutionary interest. Analysis of crosses enabled us to conclude that, in addition to previously proposed models of monogenic recessive and cumulative polymery, two genes can control a given trait interacting in a mode of dominant epistasis. This means that many-flowered axillary racemes develop in pea plants either if they bear a dominant allele of inhibiting gene ( FN ) or comprise double recessive homozygotes ( fn fn fna fna ). In the second filial progeny, 13:3 ratio can be observed with many-flowered plants prevailing.

Plant growth promoting rhizobacteria (PGPR) represent a wide variety of bacteria inhabiting the root surface and root vicinity. They are directly or indirectly involved in promoting plant growth and development via production and secretion of various regulatory compounds in the rhizosphere. PGPR are generally beneficial to a wide range of crops including maize. The main objective of this study was to determine the effect of PGPR strains on the microbial abundance in maize rhizosphere. The trial was conducted at Rimski Sancevi experimental field of Institute of Field and Vegetable Crops in Novi Sad, Serbia. The trial included five maize hybrids (NS 3014, NS 4015, NS 5043, NS 6010 and NS 6030) developed at the Institute and three treatments with microorganisms. Non-inoculated treatment was control. Inoculation was performed with Bacillus Q7, Pseudomonas PS2 and their mixture with Azotobacter chroococcum (Q7 + PS2 + AC). Application method was incorporation immediately before planting with liquid culture of strains (density 109 CFU/ml). It was observed that the certain treatment with rhizobacteria increased the number of all three studied microbial groups in the rhizosphere of the same hybrid. The best effect on the number of microorganisms in the rhizosphere of NS 6010 was achieved with Q7 + PS2 + AC, in NS 5043 with Q7 and with PS2 in NS 4015. The results obtained in this study indicate the importance of PGPR in crop production, which requires a constant expansion of knowledge about the mutual interactions of plants and microorganisms.

Breeding of novel pea cultivars is of significant interest in scope of increasing food shortages. The cultivars of new generation have to be highly technological and appropriate for mechanical treatment in all stages of planting. To provide higher outcome of plant products, pea is to be harvested for prolonged seasonal period, i.e. bred for conveyor usage. In this paper we presented the results of preliminary investigation of pea germplasm collection and studies on inheritance of flowering time in a series of crosses. We evaluated all hybrid progeny for duration of vegetation, lodging resistance and seed mass. Seven maturity groups were emphasized with most of obtained lines exhibiting an average duration of vegetation period measured as number of sterile nodes (11-15 for average fraction). As a result of this survey, the prospective genotypes for breeding new forms resistant to lodging and suitable for mechanical harvest were isolated. We propose a scheme of conveyor usage of new forms for sustainable delivery of stock for conversion industry. The obtained material is recommended for further improvement as the initial material for breeding.

Brown rot or bacterial wilt caused by bacterium Ralstonia solanacearum is the main limiting factor in potato production. Quarantine measures are necessary to avoid spread of disease to disease-free areas. R. solanacearum has been shown to contaminate watercourses from which crop irrigation is then prohibited causing further potential losses in yield and quality. The bacteria also spread via surfaces that diseased seed potatoes come into contact with. This study showed bactericidal activity of chlorine dioxide (CIO2) on R. solanacearum for disinfection of water, surface and equipment. The results showed that CIO2 solution at concentration of 2 ppm at 30 minutes of exposure time had bactericidal effect for disinfection of water. For surface and equipment disinfection, concentration of 50 ppm showed total efficacy at 30 min and 5 sec exposure time, respectively. Results suggest that use of CIO2 as a disinfectant has a potential for control of brown rot pathogen in water, storage and equipment.
