Abstract

Koruza (Zea mays L.) je zaradi svoje vsestranske uporabnosti ena najpomembnejših kmetijskih rastlin. Pridelujemo jo za prehrano ljudi in za živinorejo, kot organska masa pa je energent v bioplinarnah. Pridelek je odvisen od številnih dejavnikov, kot so hibrid, zrelostni razred, tip tal, vremenske razmere, obdelava tal ter drugi agrotehnični ukrepi in postopki. V želji po bolj trajnostni obdelavi tal se poleg konvencionalne v svetu in pri nas uvaja še ohranitvena, pri kateri ostane po obdelavi in setvi več kot 30 % obdelane površine pokrite z rastlinskimi ostanki prejšnje poljščine, tako se izognemo oranju in vsakoletnemu obračanju tal, ki lahko negativno vpliva na pestrost življenja v tleh. Vsak način obdelave zahteva specifične stroje in orodja ter seveda znanje, saj lahko z nepravilno izvedbo naredimo tlom več škode kot koristi. Smiselno se je torej zavedati, da obdelava tal brez oranja zaradi močnejše zapleveljenosti in zato večje porabe herbicidov ni vedno bolj gospodarna, niti ni povsod mogoča ali primerna, za to se minimalne obdelave ne bi smeli posluževati samo zaradi prihranjenega časa in denarja.

Secondary title: Influence of tillage on yield of maize (Zea mays L.)
Secondary abstract: Due to its general usability maize (Zea mays L.) is one of the most important plant species for agricultural production. We cultivate it for human and animal consumption, and it is also growing popular as an organic substrate in biogas plants. Yield depends on many factors such as plant variety, maturity class (FAO), soil type, weather conditions etc. Nowadays, in desire for more sustainable production we are introducing the conservation soil tillage in addition to conventional tillage by moldboard plow. At conservation tillage at least 30 % of a field stays covered with residues of previous crop. Each kind of cultivation requires specific machines and knowledge, to avoid doing more damage than benefits to our land. We should be aware that even if the conservation cultivation is cheaper and it takes less time for operations, it is not necessarily more economical or even possible and appropriate everywhere, because of permanence of weeds which results in bigger herbicide usage.
