AB  - In this study 36 maize hybrids of different FAO maturity groups were observed in three successive years (2011, 2012 and 2013), on 8 locations. The main objective of this experiment was to observe the GxE interaction concerning yield, grain moisture, grain yield per ear and test weight. The experiment was set up according to the RCBD. Based on the obtained results average estimates, CV and overall ranking of hybrids were calculated. ANOVA was applied in order to estimate the effect of factors: genotype, environment and interaction. Thus the significance of all these factors was observed. Results of this research indicate the importance and necessity of performing multilocation and multiyear trials with the aim of observation and understanding the intensity of GxE interaction, as well as its influence on the grain yield and it components.
AB  - Istraživanje je obuhvatilo 36 hibrida različitih FAO grupa zrenja, u 2011, 2012 i 2013 godini, na 8 lokaliteta. U ogledu je ispitivana interakcija genotip x sredina u pogledu stabilnosti prinosa zrna, vlage zrna, težine zrna po klipu i zapreminske mase kukuruza. Ogled je bio postavljen potpuno slučajnom blok sistemu (RCBD). Na osnovu dobijenih podataka izračunate su prosečne vrednosti, pokazatelji varijabilnosti posmatranih osobina i ukupan rang hibrida, a analizom varijanse utvrđena je značajnost efekta genotipa, sredina i interakcija. Za sve proučavane agronomske osobine, analizom varijanse su utvrđene statistički visokoznačajne vrednosti genotipa, sredina i interakcije. Najviši prosečan prinos zrna u ogledu ostvaren je u 2011. godini (11,62 t/ha), a najniži u 2012. godini (6,90 t/ha). Najniži prosečan procenat vlage zrna kukuruza u ogledu ostvaren je u veoma sušnoj 2012. godini (14,86%), dok između vrednosti ostvarenih u 2011. godini (19,47%) i 2013. godini (19,52%) nije bilo značajnije razlike. Vrednosti težine zrna po klipu kukuruza bile su direktno srazmerne vrednostima prinosa. Najveća zapreminska masa zrna kukuruza ostvarena je u sušnoj 2012. godini (74,84 kg/hl), dok je najmanje izmerena u kišovitoj 2013. godini (70,47 kg/hl). Rezultati ovog istraživanja potvrđuju neophodnost izvođenja višelokacijskih i višegodišnjih ogleda u cilju što boljeg sagledavanja intenziteta interakcija genotip x sredina, i njihovog uticaja na prinos i komponente prinosa hibrida kukuruza različitih FAO grupa zrenja na teritoriji Srbije. Da bi proizvodnja kukuruza bila stabilna, farmerima koji nemaju mogućnost navodnjavanja, već kukuruz gaje u suvom ratarenju, treba savetovati da seju hibride različite dužine vegetacije.

AB  - The present paper shows results obtained on effects of priming of sunflower seeds, subjected to accelerated ageing and the cold test, on seed vigour. Seeds were primed with distilled water, the potassium nitrate solution (0.2%) and the gibberellic acid solution (0.04%). The following parameters were tested: energy of germination, germination, proportion of abnormal seedlings, lengths of roots and shoots of normal seedlings. Accelerated ageing in the course of 3 and 5 days resulted in a statistically significant reduction in energy of germination and germination; it adversely affected the length of roots and shoots and it increased the proportion of abnormal seedlings. Seed priming with all three solutions mitigated adverse effects of 3-day accelerated ageing on energy of germination. Furthermore, seed priming with gibberellic acid prior to 3-day accelerated ageing positively affected seed germination and neutralized a negative effect of accelerated ageing on the number of abnormal seedlings, as well as on lengths of shoots and roots of normal seedlings. The cold test (at 5°C for 7 days) negatively affected energy of germination and the root length, increased the proportion of abnormal seedlings and did not affect seed germination. Priming of seeds with distilled water prior to the cold test completely neutralized the adverse effect of low temperatures on energy of germination. Finally, priming of seeds with all three solutions completely neutralized the adverse effect of cold test on the root length.

AB  - Thousand-seed weight and total germination from the first production year and two seed harvests were measured in tetraploid Italian ryegrass (cv. Tetraflorum) to study variations in seed quality. Four-year field experiments were carried out (2002-2006) in western Serbia and Italian ryegrass was established with three row spacings (20, 40 and 60 cm), four seeding rates (5, 10, 15 and 20 kg ha-1) and using four spring nitrogen rates (0, 50, 100 and 150 kg ha-1). High seed quality was obtained, except for the first experimental year (2003) and the second seed harvests which yielded the seed of unsatisfactory quality and validity. Applied factors and treatments did not change seed quality significantly unlike environmental conditions of production years which had considerable influence on seed quality.

Četvorogodišnji poljski eksperiment je izveden (2002-2006) u zapadnoj Srbiji i italijanski ljulj je zasnivan na 3 međuredna rastojanja (20, 40 i 60 cm), četiri setvene norme (5, 10, 15 i 20 kg ha-1) i primenom četiri doze prihrane azotom (0, 50, 100 i 150 kg ha-1). Ostvaren je visok kvalitet semena, izuzev prve godine ispitivanja (2003), a ostvarena je i druga semenska žetva sa semenom nezadovoljavajućeg kvaliteta i upotrebljivosti. Primenjeni faktori i nivoi ispitivanja nisu značajno menjali kvalitet semena za razliku od vremenskih uslova u proizvodnim godinama koji su značajno uticali na kvalitet semena.
