| مستخلص: | Značaj lucerke u srpskoj poljoprivredi, kao i njena velika tržišna vrednost nameće stalnu potrebu za unapređenjem proizvodnje ove krmne biljke koja zauzima velike površine, kako u svetu tako i u našoj zemlji. Sveobuhvatni cilj doktorske disertacije je da se oceni uticaj različitih sistema gajenja (režima kosidbe) na prinos i hranljivu vrednost lucerke, doprinese rešavanju praktičnih pitanja u proizvodnji lucerke (redefiniše optimalna količina semena za setvu) i odredi fenološka faza u momentu kosidbe u kojoj se postiže balans prinosa i kvaliteta suve materije lucerke. Trogodišnje istraživanje (2010-2012) je izvedeno na oglednim poljima Odeljenja za krmno bilje Instituta za ratarstvo i povrtarstvo u Novom Sadu, na dva lokaliteta (Rimski Šančevi i Čenej). Poljski ogled je postavljen po slučajnom blok sistemu u tri ponavljanja na oba lokaliteta. U radu su analizirane četiri sorte lucerke (Banat VS, Nijagara, NS Medijana ZMS V i NS Alfa); dve setvene norme od 8 i 16 kg/ha i tri sistema kosidbe u zavisnosti od fenološke faze razvoja biljaka: I – rani (10% cvetalih biljaka), II – srednje rani (50% cvetalih biljaka), i kasni (početak zametanja mahuna). Tretmani su aranžirani po sistemu podeljenih parcela (split-plot metod), a kao osnovna parcela (veličina 72 m2) korišćena je setvena norma, dok su sve ostale kombinacije sorti i režima kosidbe tretirane kao podparcele (veličina 6 m2). Dimenzije podparcele su 5 m dužina i 1,2 m širina, sa međurednim razmakom od 20 cm. Razmak između blokova je 1 m. Među ispitivanim sortama nije bilo značajne razlike u visini prinosa i komponentama prinosa suve materije lucerke, kao ni u pogledu njihovog kvaliteta. Različite količine semena za setvu lucerke, od 8 i 16 kg/ha, nisu uticale na prinos suve materije kao ni na komponente prinosa (visina biljaka, udeo lista u prinosu, broj izdanaka i broj biljaka). U umereno-kontinentalnim klimatskim uslovima, kakvi vladaju u većem delu u Republike Srbije, nema opravdanja povećanja setvene norme izn The importance of alfalfa in Serbian agriculture, as well as its high market value, imposes a constant need for the improvement of this forage crop production that occupies large areas both in the world and in our country. The overall objective was to evaluate the effect of different growing systems (cutting regimes) on yield and nutritional value of alfalfa, contribute to solving practical issues in alfalfa production (redefine the optimal amount of seed for sowing) and specify the phenological stage in the moment of cutting when the balance of yield and dry matter quality of alfalfa is achieved. Three-year study (2009-2012) was carried out on experimental fields of Forage Crops Department of the Institute of Field and Vegetable Crops in Novi Sad, at two sites (Rimski Šančevi and Čenej). Field trial was set up in a randomized block design with three replications at both sites. Four cultivars of alfalfa were studied in this dissertation (Banat VS, Nijagara, NS Medijana ZMS V and NS Alfa); two sowing rates from 8 and 16 kg/ha and three cutting systems depending on crop phenological stage of development: I – early (10% of flowering plants), II – medium early (50% of flowering plants), and late (beginning of pod setting). Treatments were arranged by split-plot method, and the basic plot (size 72 m2) was used as the sowing rate, while all the other combinations of cultivars and cutting regimes were treated as sub-plots (6 m2). Sub-plot dimensions were 5 m in length and 1.2 m in width, with interrow distance of 20 cm. Inter-block distance was 1 m. There were no significant differences in yield and yield components of alfalfa dry matter, or in their quality, among the tested cultivars. Different amounts of seed for alfalfa sowing, from 8 and 16 kg/ha, did not affect the dry matter yield, or the yield components (crop height, leaf ratio in yield, number of shoots, and number of plants). In moderate-continental climatic conditions, which are present in the majority of the |
