dc.description.abstractOwing to its characteristics, alfalfa (Medicago sativa L.) is important for the production of high-quality fodder. Its seed yields vary widely and are heavily influenced by environmental factors. The synchronization of alfalfa seed harvest requirements with environmental factors is partially possible through the cutting system. The purpose of this research is to investigate the influence of a cutting schedule on the germination and size of alfalfa seeds. The pre-cutting time did not significantly affect the absolute mass within a 1 pre-cut system, whereas the number of pre-cuts had a reducing impact on the absolute mass within a 2 pre-cut system. The cutting system had no significant effects on seed germination. While the ecological conditions during the year had significant impacts, the lowest seed germination was recorded in the year with the highest rainfall during the summer period.en
dc.description.abstractPlava lucerka (Medicago sativa L.) je zbog svih svojih osobina značajna u proizvodnji kvalitetne kabaste hrane. Prinosi semena u Srbiji jako variraju u zavisnosti od godine i kreću se, od onih koji ne opravdavaju troškove žetve, do preko 1000 kg ha-1, dok se u glavnim proizvodnim reonima u svetu beleže stabilniji prinosi. Različitim vremenom kosidbe predotkosa moguće je delimično upravljati vremenom cvetanja semenskog otkosa i na taj način uticati na sinhronizaciju cvetanja i oprašivanja, formiranja mahuna, sazrevanja i žetve sa periodom godine kada postoje najpovoljniji uslovi za to. Cilj ovih istraživanja je da se u poljskim uslovima ispita uticaj vremena kosidbe na klijavost i krupnoću semena lucerke. Praćeni su uticaji različitih rokova kosidbe prvog predotkosa u proizvodnji semena iz drugog otkosa i uticaj dva predotkosa u proizvodnji semena iz trećeg otkosa. Vreme predotkosa u sistemu sa jednim predotkosom nije značajno uticalo na apsolutnu masu, dok je u varijanti sa dva predotkosa ostvarena manja apsolutna masa. Posmatrano zajedno u trogodišnjem periodu ostvarena je prosečno masa 1000 semena od 1,92 g, a apsolutna masa se kretala u intervalu od 1,75 g do 2,07 g. Sistem kosidbe nije imao značajan uticaja na klijavost semena. Ekološki uslovi u toku godine imali su značajan utiacaj na klijavost i najmanja klijavost je ostavrena u godini sa najviše padavina u letnjem periodu. Prosečna klijavost je iznosila 82,11%, sa variranjem od 71,50% do 88,40%.sr
