CRIMSON CLOVER (Trifolium incarnatum L.) SPRING PLANTING IS NOT ADEQUATE FOR CULTIVATION IN NORTH-EAST SLOVENIA

V poljskem mikroposkusu, ki je bil zasnovan spomladi leta 2015 na posestvu Fakultete za kmetijstvo in biosistemske vede v Hočah (46°29\u27 N in 15°39\u27 E), smo ugotavljali vpliv časa setve na rast in razvoj inkarnatke (Trifolium incarnatum L.). Poskus je bil zasnovan po metodi naključnega bloka v štiri ponovitvah. Posamezno obravnavanje so predstavljali različni termini setve (1) 2. 4. 2015, (2) 7. 5. 2015, (3) 1. 7. 2015, (4) 2. 9. 2015. Statistično značilno smo ob košnji ugotovili najvišje pridelke sveže zelene krme (ZM t ha-1), suhe snovi (SS t ha-1) in tudi višino rastlin (cm) pri košnji zgodnjega spomladanskega roka setve (1). Na posevku se je pred košnjo začela zelo hitro pojavljati plesen kot negativni faktor za pridelavo inkarnatke v tem času. Z vsako naslednjo košnjo, kasneje sejane inkarnatke (2,3), so se posamezni merjeni parametri zmanjševali. Nasprotno so se bolezni vedno bolj širile.In a micro field experiment, which was carried out in the spring of 2015 on the estate of the Faculty for Agriculture and Life Sciences in Hoče (46°29\u27 N and 15°39\u27 E), we tried to determine the influence of the sowing time on the growth and development of crimson clover (Trifolium incarnatum L.). The experiment followed the arbitrary block method in four repetitions. Each treatment was performed in different sowing times: (1) 2 April 2015, (2) 7 May 2015, (3) 1 July 2015 and (4) 2 September 2015. We found a statistically typical highest value for fresh green mass (GM t ha-1), dry matter (DM t ha-1), and height of plants (cm) in the cutting of the early spring planting. The tillage showed signs of mould very early, even before the cutting, indicating the mould as a negative factor of crimson clover cultivation during that time. With each subsequent harvesting of crimson clover that was sowed later (2, 3), the measured parameters decreased. On the other hand, the diseases spread more prominently
