Preliminarni rezultati ispitivanja prinosa krme nekih kupusnjača

Amnog the most importnat forage brassicas are fodder kale (Brassica oteracea L. var. viridis L), oilseed rape (Brassica napus L. var. napus) and white mustard (Sinapis alba L. subsp. atoa). A small-plot trial has been carried out at the Experimental Field of the Institute of Field and Vegetable Crops at Rimski Šančevi, including two winter cultivars of fodder kale, HS-Bikovo and K-357, two winter cultivars of oilseed rape, Bana-canka and Slavica, two spring cultivars of oilseed rape. Global and Qalant, and two spring cultivars of white mustard, MMB 001 and MMB 002. The winter cultivars were sown in September 2005 and the spring cultivars in March 2006, while all eight cultivars were cut at the stages of budding and beginning of flowering, with all cultivars producing two cuttings. The highest average total green forage and forage dry matter yields were in fodder kale (70,5 t ha-1 and 6,0 t ha-1), among the species, and the fodder kale cultivar K-357 (72,5 t ha-1 and 6,0 t ha-1), among the cultivars. White mustard had the highest portion of forage dry matter (0,16).Među najvažnijim krmnim kupusnjačama su stočni kelj (Bras sica oleracea L. var. viridis L), uljana repica (Bras sica napus L. var. napus) i bela slačica (Sinapis alba L. subsp. alba). Mikroogled sa po dve ozime sorte stočnog kelja (NS-Bikovo i K-357) i uljane repice (Banaćanka i Slavica) i po dve jare sorte uljane repice (Global i Galant) i bele slačice (MMB 001 i MMB 002) je izveden na Oglednom polju Instituta za ratarstvo i povrtarstvo na Rimskim Šančevima. Ozime sorte posejane su u septembru 2005. godine, a jare u martu 2006. godine, dok je svih osam sorti košeno dva otkosa, u fazi butonizacije i početka cvetanja. Među vrstama, najvišim prosečnim ukupnim prinosom zelene krme i suve materije krme odlikovao se stočni kelj (70,5 t ha-1 i 6,0 t ha-1), a među sortama, stočni kelj K-357 (72,5 t ha-1 i 6,0 t ha-1). Bela slačica se odlikovala najvišim prosečnim udelom suve materije krme (0,16)
