In this paper influence of two tillage systems (conventional and conservation)
on sunflower and maize yield is analyzed. The experiments are carried on production
fields of Maize Research Institute "Zemun Polje".
The conventional tillage system gave satisfying yields of both plants. This type of
tillage is acceptable in years with medium rainfall during the vegetation period. When
amount of precipitation was not evenly distributed during the year, yield was
significantly lower, or even omitted if the differences in amount of precipitation were
extreme.
With conservation tillage system, the yield was higher, in comparison with
conventional system, even in the years with medium amount of precipitation during the
vegetation period. Sunflower and maize yields were 8.6% and 9.9% higher with
conservation tillage system than with conventional system.
The research is necessary to continue in order to see the effects of conservation
tillage on other breeding plants, and also for observing the effects of continuous usage of
this tillage system (in second, third and fourth year of production). U radu je analiziran uticaj dva sistema obrade zemljišta: konvencionalnog i
konzervacijskog na promenu prinosa suncokreta i merkantilnog kukuruza. Ogledi su
izvedeni na proizvodnim površinama Instituta za kukuruz "Zemun Polje".
Konvencionalni sistem obrade dao je zadovoljavjuće prinose kod obe kulture. Ovaj
način obrade zemljišta je prihvatljiv u proizvodnoj godini sa umerenim padavinama
tokom vegetacionog perioda. Prinosi u godinama sa neravnomernim rasporedom
padavina su značajno manji, dok u ekstremnim godinama često izostaju.
Konzervacijskim sistemom obrade postižu se veći prinosi u poređenju sa
konvencionalnim sistemom, čak i u godinama kada je količina padavina tokom
vegetacionog perioda umerena (prinos je veći u odnosu na konvencionalni sistem obrade
za: suncokret 8.6%, merkantilni kukuruz 9.9%).
Ova istraživanja je potrebno nastaviti zbog sagledavanja efekata primene sistema
konzervacijske obrade zemljišta i na druge gajene kulture, kao i radi sagledavanja efekata
produženog dejstva primene ovog sistema obrade (u drugoj i trećoj proizvodnoj godini).
