AB  - Field pea (Pisum sativum L.) has the potential to be a suitable companion crop for the establishment of red clover (Trifolium pratense L.), as it is fast growing and is harvested early, and thus reduces the duration of competition and allows light to be transmitted through its canopy to an undersown species more so than other companion crops such as small grains. The aim of this study was to determine the suitability of field pea as a companion crop for red clover, and in particular to determine the effect of pea cultivar and plant population density. The field experiment comprised 2 sowing years, (2004 and 2005), and the first cut in the first full harvest year in 2005 and 2006. The factorial component of the experiment involved 2 pea varieties (Jezero: semi-leafless; Javor: normal leaves with reduced leaflet size) and 3 densities (30, 60, and 90 plants m(-2)). Two control treatments were also included in the experiment, i.e. red clover grown as pure stand (control I) and red clover with oat as a cover crop (control II). When the field pea had reached the harvestable stage all plots were cut, followed by 2 additional cuts in the sowing year. Yields at the first cut in the following year were also recorded. Forage and protein yields, as well as the weed proportion were measured. On average, control II produced the highest forage yield, followed by pea as the cover crop; the lowest yield was obtained in the pure stand of red clover. Field pea cultivar yields did not differ significantly. The highest average yield was obtained with 90 plants m(-2). The first cut comprised the highest proportion of annual yield (50%-69% when field pea was included). Red clover establishment was not adversely affected by competition from peas. As crude protein content did not vary much, crude protein yield followed the same trend as forage yield (r = 0.83).

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.

AB  - In the recent trends in plant production such as sustainable agriculture and organing farming, cover crops became more important and practically non missing link in crop rotation.

AB  - Ozimi krmni međuusevi postaju sve značajniji i zastupljeniji u strukturi setve sa pojavom novih pravaca u biljnoj proizvodnji, kao što su održiva poljoprivreda i organska proizvodnja. Osnovni cilj njihovog gajenja je zaštita agroekološkog sistema, što se ostvaruje, pre svega smanjenjem ili potpunom izostavljanju upotrebe mineralnih đubriva i pesticida. Ozimi krmni međuusevi imaju izrazito važnu ulogu, kao neizostavna karika u proizvodnji zdravstveno bezbedne hrane, uz očuvanje prirodnih resursa, pri čemu se istovremeno ostvaruje i profit. Ključni pristup za takvu koncepciju je viđenje farme kao agroekosistema koji predstavlja dinamičan odnos zemljišnih, vremenskih, bioloških i ljudskih resursa uključenih u biljnu i stočarsku proizvodnju. Ozimi krmni međuusevi predstavljaju čiste useve ili njihove smeše između dva glavna useva. Značaj gajenja krmnih međuuseva ogleda se u: smanjenju troškova đubrenja, čuvanju zemljišne vlage i ispiranje hraniva, popravci osobina zemljišta, sprečavanju erozije smanjenju upotrebe pesticida i očuvanju životne sredine. Navedene koristi od ozimih krmnih međuuseva značajno zavise od konkretnih agroekoloških uslova proizvodnje. U radu su analizirane sve navedene koristi, odnosno značaj ozimih krmnih međuuseva.

Cover crops are grown as pure crops or as plant mixture between two cash crops. According to sowing time cover crops are sows as winter cash crops. The main benefits of cover crops are: reducing fertilizer costs conservation of soil moisture, reducing of nutrients leaching, improving of soil properties, reducing the needs for pesticides, prevention of soil erosion, water quality protection and help safe guard personal health. Benefits vary by location and season, but at least two or three occur with any cover crop., Ozimi krmni međuusevi postaju sve značajniji i zastupljeniji u strukturi setve sa pojavom novih pravaca u biljnoj proizvodnji, kao što su održiva poljoprivreda i organska proizvodnja. Osnovni cilj njihovog gajenja je zaštita agroekološkog sistema, što se ostvaruje, pre svega smanjenjem ili potpunom izostavljanju upotrebe mineralnih đubriva i pesticida. Ozimi krmni međuusevi imaju izrazito važnu ulogu, kao neizostavna karika u proizvodnji zdravstveno bezbedne hrane, uz očuvanje prirodnih resursa, pri čemu se istovremeno ostvaruje i profit. Ključni pristup za takvu koncepciju je viđenje farme kao agroekosistema koji predstavlja dinamičan odnos zemljišnih, vremenskih, bioloških i ljudskih resursa uključenih u biljnu i stočarsku proizvodnju. Ozimi krmni međuusevi predstavljaju čiste useve ili njihove smeše između dva glavna useva. Značaj gajenja krmnih međuuseva ogleda se u: smanjenju troškova đubrenja, čuvanju zemljišne vlage i ispiranje hraniva, popravci osobina zemljišta, sprečavanju erozije smanjenju upotrebe pesticida i očuvanju životne sredine. Navedene koristi od ozimih krmnih međuuseva značajno zavise od konkretnih agroekoloških uslova proizvodnje. U radu su analizirane sve navedene koristi, odnosno značaj ozimih krmnih međuuseva.",
