Prinos sorti žutog zvezdana na zemljištu bazne reakcije

The aim of the study was to analyze the forage and seed yield of birdsfoot trefoil cultivars on the soil base reaction. The field trial was set 2014th in Čačak on soil type fluvisol (pHH2O 7.8). The experiment was set a randomized complete block design with three replications with a plot size of 6x1m. The birdsfoot trefoil cultivars K-37, Zora and Bull were planted at a row spacing of 12.5 cm and a seeding rate of 10 kg ha-1. Cultivars among themselves, did not differ significantly in terms of forage yield, hay yield and dry matter content. The average forage yield in the first cut in the second year of cultivation was 26.53 t ha-1. The forage yield in the first cut in the third year of cultivation was 26.56 t ha-1 and in the second cut 11.77 t ha-1. The average seed yield of cultivars in the second growth in the second year of cultivation was 472.3 kg ha-1. Birdsfoot trefoil cultivars among themselves, did not differ significantly in terms of seed yield components. However, Zora cultivar had significantly higher seed yield potential, compared to other cultivars. These results do not differ from results obtained under similar conditions on acid soil.Cilj istraživanja je bio da se analizira prinos krme i semena sorti žutog zvezdana na zemljištu bazne reakcije. Ogled je postavljen 2014. godine u Čačku na zemljištu tipa fluvisol (pHH2O 7,8). Poljski eksperiment je postavljen po potpuno slučajnom blok sistemu u tri ponavljanja, sa veličinom elementarne parcele 6x1m. Sorte žutog zvezdana K-37, zora i Bull su zasejane na rastojanju 12,5 cm međuredno, sa količinom semena 10 kg ha-1. Sorte se među sobom nisu značajno razlikovale u pogledu prinosa krme, prinosa sena i sadržaja suve materije. Prosečan prinos krme u prvom otkosu u drugoj godini proizvodnje je bio 26,53 t ha-1. Prinos krme u prvom otkosu u trećoj godini proizvodnje je bio 26,56 t ha-1, a u drugom otkosu 11,77 t ha-1. Prosečan prinos semena sorti u drugom porastu u drugoj godini gajenja je bio 472,3 kg ha-1. Sorte žutog zvezdana se među sobom nisu značajno razlikovale u pogledu komponenti prinosa semena. Međutim, sorta zora je imala značajno veći potencijalni prinos semena u odnosu na ostale sorte. Navedeni rezultati se ne razlikuju od rezultata dobijenih u sličnim uslovima na kiselom zemljišu
