AB  - Years which are encompassed by the research, according to the mean daily air temperatures and precipitation, were characterized by the frequent occurrence of extremely warm and dry vegetation periods. The aim of the research is to estimate the economic viability of the production of maize, potatoes and tomatoes in terms of FI (full irrigation). The assessment of the economic viability of the application of the irrigation system when it comes to maize and potato production is done on the basis of a comparative analysis of the realized profit in the natural water regime and FI, whereas in the case of greenhouse tomato production it is done on the basis of comparative analysis of profit achieved in terms of RDI (regulated deficit irrigation) and FI. The research results indicate a positive economic effect of the irrigation system implementation because in our climate the water needs of a culture cannot be satisfied solely by precipitation, and thus water deficit occurs. This lack of rainfall causes yield reduction because it is the main parameter which increases the production profitability. Therefore, increasing the area under irrigation is very important.
AB  - Godine obuhvaćene istraživanjem, shodno srednjim dnevnim temperaturama vazduha i sumi padavina, odlikovala je učestala pojava sušnih i ekstremno toplih vegetacionih perioda. Cilj istraživanja je ocena ekonomske isplativosti proizvodnje kukuruza, krompira i paradajza u uslovima FI. Ocena ekonomske isplativosti primene sistema za navodnjavanje u slučaju proizvodnje kukuruza i krompira izvršena je na osnovu komparativne analize ostvarenog profita u prirodnom vodnom režimu i FI, dok u slučaju plasteničke proizvodnje paradajza izvršena na osnovu komparativne analize profita ostvarenog u uslovima RDI i FI. Rezultati istraživanja ukazuju na pozitivan ekonomski efekat primene sistema za navodnjavanje jer u našim klimatskim uslovima kulture svoje potrebe za vodom ne mogu da zadovolje isključivo padavinama, te se tako javlja deficit vode. Upravo taj nedostatak padavina uslovljava redukciju prinosa kao glavnog parametra u povećanju profitabilnosti proizvodnje i iz tog razloga bi povećanje površina pod sistemima za navodnjavanje bilo izuzetno značajno.

AB  - Quinoa (Chenopodium quinoa Willd.) is a highly nutritious Andean seed crop which shows great potential to grow under a range of different stress environments. The objective of this study was to investigate the effect of drought on water regime and the growth of quinoa variety KVL52 in controlled conditions. The results of the present experiment indicate that the reaction of quinoa plants to drought are based on drought avoidance mechanisms: reduced transpiration and sustained water uptake. Transpiration was reduced due to the decrease of stomatal conductance and leaf area development. These results could be of practical importance for testing the possibility of growing quinoa as a new drought resistant crop in Serbia.
AB  - Kvinoja (Chenopodium quinoa Willd.) je nutritivno visoko vredna kultura poreklom sa Anda, koja se može gajiti u različitim stresnim uslovima spoljašnje sredine. Cilj ovih istraživanja je bio da se ispita efekat suše na vodni režim i rastenje sorte kvinoje KVL52 u kontrolisanim uslovima gajenja. Dobijeni rezultati ukazuju da su reakcije kvinoje na sušu bazirane na mehanizmu izbegavanja suše: redukciji transpiracije i održanju usvajanja vode. Transpiracija je redukovana zahvaljujući opadanju provodljivosti stoma i redukciji lisne površine. Ovi rezultati mogu biti od praktičnog značaja za testiranje mogućnosti gajenja kvinoje kao kulture koja je otporna na sušu i nova za gajenje u Srbiji.

AB  - Cucumber (Cucumis sativus L) is an important member of the Cucurbitaceae family. Production of healthy nursery is necessary for high-quality production of this crop in greenhouses and in fields. With the idea of minimizing the use of pesticides and mineral fertilizers to preserve soil quality, we investigated the effects of plant growth promoting bacteria (PGPB) on growth promotion and protection of cucumber plants from phytopathogenic fungi. The effects of Pseudomonas spp. strains with different antifungal activities and Bacillus sp. Q10 strain with PGP activity were tested on cucumber plants. Antagonistic activity of Pseudomonas spp. against the growth of several phytopathogenic fungi isolated from cucumber: F. acuminatum, B. cinerea and A. niger, was observed. The influences of overnight cultures, supernatants and heat-stable antifungal factors were tested on the phytopathogenic fungi in vitro. Pseudomonas sp. K35 and K24 strains were more effective than P. chlororaphis Q16 and Pseudomonas sp. K27, showing 70-80% of fungal growth inhibition regardless of culture or fraction applied. The good antagonists that belong to pseudomonads and Bacillus sp. Q10 strain were used as mixtures for estimation of plant growth and health promoting effects on cucumber plants. Growth dynamics differed depending on the applied strain of Pseudomonas sp. The M3 treatment (a mixture of Bacillus sp. Q10 and P. chlororaphis Q16) stimulated the initial phase of growth, while M4 (a mixture of Bacillus sp. Q10 and Pseudomonas sp. K24) resulted in the maximal height at the final measurement. Significant differences in leaf and plant weight (M4), and leaf weight (M5, containing K35 strain) were found after the treatments. No significant differences in chlorophyll and NBI level were observed in any of the tested combinations. The obtained results suggested that M3 was suitable for stimulation of the early phase of cucumber growth, while the mixtures M4 and M5 improved plant protection and stimulated the later phases of cucumber growth.
AB  - Krastavac (Cucumis sativus L) je važan predstavnik familije Cucurbitaceae, a proizvodnja zdravog rasada je nephodna za visoku produktivnost u plastenicima i na otvorenom polju. Da bi se umanjila primena pesticida i mineralnih đubriva i pri tome sačuvalo zemljište, ispitan je uticaj bakterija stimulatora biljnog rasta (PGPB) na rast biljaka i zaštitu od patogena. Primenjeni su sojevi Pseudomonas spp. sa različitim antimikoznim delovanjem i Bacillus sp. soj Q10 sa PGP aktivnošću. Praćena je antagonistička aktivnost Pseudomonas spp. na fitopatogene gljive izolovane sa biljaka krastavca: F. acuminatum, B. cinerea i A. niger. Testiran je uticaj prekonoćne kulture bakterija, supernatanta i termostabilnih antifungalnih faktora na rast ovih fitopatogena. Pseudomonas sp. K35 i K24 sojevi, koji pokazuju 70-80% inhibicije rasta gljiva bez obzira na primenjenu kulturu ili frakciju, efektivniji su od P. chlororaphis Q16 i Pseudomonas sp. K27. Sojevi Pseudomonas spp., koji su ispoljili visok stepen antagonizma, kombinovani su sa sojem Bacillus sp. Q10 i procenjen je uticaj na rast i zdravstveno stanje biljaka krastavca. U zavisnosti od primenjenog soja Pseudomonas sp., razlikovala se dinamika rasta krastavca. Tretman M3 - kombinacija Bacillus sp. Q10 i P. chlororaphis Q16 uticala je na početnu fazu porasta biljaka, dok je treatman M4 - kombinacija Bacillus sp. Q10 i Pseudomonas sp. K24, imala najviše uticaja na visinu biljke na kraju merenja. Uočene su značajne razlike za masu lista i masu biljke (M4) i masu lista (M5 sa sojem K35), dok sadržaj hlorofila i nivo NBI nisu imali značajne razlike kod svih ispitivanih kombinacija. Dobijeni rezultati ukazuju da je M3 pogodan za rane faze razvoja biljke, a kombinacije M4 i M5 pogodne su za zaštitu biljaka i u kasnijim fazama porasta biljaka. Potpuna ekspresija PGP svojstava za M4 i M5 može se utvrditi tek posle testiranja na siromašnim supstratima, koji će biti upoređeni sa rezultaima dobijenim na supstratima sa dovoljno hranljivih materija.
