AGROTECHNICS OF OILSEED RAPE

Uljana repica je jednogodišnja kultura koja kao plod daje komušku ispunjenu sitnim sjemenkama. Zrno repice sadrži 40-48 % ulja i 18-25 % proteina. U Hrvatskoj se uzgaja ozima kupusna uljana repica Brassica napus subspec. oleifera ,s osnovnom namjenom dobivanja ulja. U današnje vrijeme se sve više sije za proizvodnju ekološkog goriva, biodizela. Repica ima određene zahtjeve prema toplini, oborinama, tlu i svjetlosti. Uz ove agroekološke čimbenike potrebno je primijeniti punu agrotehniku da bi ostvarili visoke prinose i kvalitetu zrna. Vršenje se obavlja kada je oko 80 % komuški zrelo, tj. kada poprimi žuto-smeđu boju. Kako bi smanjili dodatne gubitke rasipanja zrna u žetvi, na heder postavljamo izduženu platformu (stol za uljanu repicu) , te s obje strane bočne kose. S obzirom na površine u RH pod uljanom repicom koje znatno osciliraju posljednih desetak godina, pretpostavka je da će se te površine povećavati upravo zbog široke upotrebe u farmaceutskoj i kozmetičkoj industriji, kao i za proizvodnju biodizela.Oilseed rape is a hardy crop which gives fruit of pods filled with small seeds. Grain of oilseed rape contains 40-48% of oil and 18-25% of protein. In Croatia winter cabbage rapeseed Brassica napus subspec. oleifera is cultivated the most with the primary purpose of obtaining the oil. Nowadays more and more is sown to produce environmentally-friendly fuel, biodiesel. Oilseed rape has certain demands of heat, precipitation, soil and light. In addition to these agro-ecological factors is necessary to apply the full cultural practices to achieve high yields and grain quality. The harvest starts when about 80% of fruit pods are ripe, ie, when it takes on a yellow-brown color. To reduce additional losses of dissipation grain at harvest, on the header we set elongated platform (rape cutter), and on both sides of the side cutter. Due to the surface in Croatia under rapeseed which significantly oscillate last ten years, the assumption is that these surfaces will increase because of the widespread use in the pharmaceutical and cosmetics industry, as well as for the production of biodiese
