Effect of Soil Liming On the Yield of Birdsfoot Trefoil Cultivars in the Third Year of Production

Abstract

In less favorable growing conditions, especially in terms of climate and soil to produce sufficient quantities of qality animal feed, special attention should be paid to the cultivation of birdsfoot trefoil (Lotus corniculatus L.). The aim of the study was to analyze the effect of liming (control - without CaO and treatment with 3 t ha-1 CaO) on forage yield, hay yield and dry matter content in the forage of birdsfoot trefoil cultivars (K-37 and Rocco) on acid soil. The field trial was set up in 2012 in Čačak on the loessivized vertisol soil type (pHH2O 4.8). Sowing was done at a row spacing of 20 cm and a seeding rate of 18 kg seed ha-1. The results indicate that was birdsfoot trefoil to a great extent tolerant to acid soil. Soil liming had a positive effect on forage yield and hay yield of birdsfoot trefoil, only in the cultivar K-37.

U manje pogodnim uslovima uspevanja, pre svega u pogledu klime i zemljišta, u cilju proizvodnje dovoljnih količina kvalitetne kabaste stočne hrane, posebnu pažnju treba posvetiti gajenju žutog zvezdana (Lotus corniculatus L.). Cilj rada bio je da se na kiselom zemljištu analizira uticaj kalcizacije (kontrola - bez CaO i tretman sa 3 t ha-1 CaO) na prinos krme, prinos sena i sadržaj suve materije u krmi sorti žutog zvezdana (K-37 i Rocco). Poljski ekseriment je postavljen 2012. godine u Čačku na zemljištu tipa lesivirana smonica (pHH2O 4,8). Setva je obavljena na rastojanju od 20 cm međuredno sa 10 kg ha-1 semena. Dobijeni rezultati ukazuju da je žuti zvezdan u velikoj meri tolerantan na uslove kiselog zemljišta. Kalcizacija zemljišta je imala pozitivan uticaj na prinos krme i sena žutog zvezdana jedino kod sorte K-37.
