AB  - In Vojvodina region, water deficit during the growing season is a major factor limiting maize production. Therefore, to achieve the ideal soil water content in this region, it is of crucial importance to optimize irrigation. The effects of different irrigation levels with sprinkler irrigation system on crop yield, yield components, water use, water (WUE) and irrigation water use (IWUE) efficiency of maize (Zea mays L) were investigated in Vojvodina (northern Serbia), on a Calcaric Chernozem soil in temperate environment for 3 consecutive years (2006-2008). Maize was subjected to four irrigation regimes, as follows: non limited irrigation (I-100), 75% of non-limited irrigation (I-75), 50% of non-limited irrigation (I-50), and rainfed (non-irrigated) as the control (I-0). The irrigation treatments were arranged in a complete randomized block design with 4 replicates. Results showed that maize grown in rainfed conditions had high annual variability, mainly due to amount of rainfall and its distribution during the crop-growing seasons. A significant irrigation effect was found for yield, yield components and others investigated parameters under study. Water stress had significant impact on yield response: as an average of the three years, a grain yield increase of 47.8, 32.8, and 22.9% was observed in I-100, I-75 and I-50 treatments compared to rainfed (I-0) treatment, respectively. Yield increased linearly with seasonal crop evapotranspiration and irrigation amount. Furthermore, WUE is maximized with a moderate water deficit (I-50), while IWUE is the highest in I-100 treatment. The deficit irrigation stress index, DISI, decreased with increasing irrigation rate. The results revealed that irrigation is necessary for maize cultivation because rainfall is insufficient to meet the crop water needs in Vojvodina. In addition, the study indicated that the irrigation regime of 25% water saving (I-75) could ensure satisfactory grain yield of maize and increment of WUE.

AB  - Pathogenicity of 10 Fusarium verticillioides isolates, originated from grain of wheat (five isolates) and maize (five isolates), were studied under greenhouse conditions. Based on different parameters of the pathogenicity estimate (a scale for % of nonemerged plants, % of survived plants, plant vigour - the growth and dry weight of roots and epicotyls and disease severity) it was determined that all F. verticillioides isolates expressed a different degree of pathogenicity. According to % of nonemerged plants six three and one F. verticillioides isolates expressed low, moderate and high degree of pathogenicity, respectively. All F. verticillioides isolates reduced the plant survival rate and vigour, while the disease severity ranged from 2.0 to 3.54. Two types of nit mutants, nit1 and NitM, were obtained by the use of the method of vegetative compatibility. The frequency of nit1 mutants was greater (58.79%) than the frequency of NitM mutants (5.77%). A total of 10 vegetative compatibility groups (VCGs) of F. verticillioides were established in the complementation tests. These results point out to a high genetic diversity of F. verticillioides population.
AB  - Patogenost 10 izolata F. verticillioides, poreklom iz zrna pšenice (5 izolata) i kukuruza (5 izolata), proučavana je u uslovima staklenika. Na osnovu različitih parametara ocene patogenosti (skala za % neizniklih biljaka, % preživelih biljaka, vigora biljaka - porast i suva težina korena i epikotila, i intenziteta bolesti) ustanovljeno je da su svi ispitivani izolati F. verticillioides ispoljili različit stepen patogenosti. Prema % neizniklih biljaka 6 izolata ispoljilo je nisku, 3 izolata srednju i jedan izolat F. verticillioides visoku patogenost. Svi ispitivani izolati F. verticillioides su prouzrokovali smanjeno preživljavanje i vigor biljaka, sa intenzitetom bolesti od 2.0 do 3.54. Primenom metode vegetativne kompatibilnosti izolovane su dve vrste nit mutanata, nit1 i NitM. Učestalost mutanata nit1 je bila veća (58.79%) u odnosu na NitM mutante (5.77%). U komplementarnim testovima ustanovljeno je 10 vegetativno kompatibilnih grupa (VCG) F. verticillioides što ukazuje na visok genetički diverzitet populacije ovog patogena.
