In the year 2003, we had a field experiment on the field of the Biotechnical
faculty. It was the experiment with five procedures of mechanical and chemical care of
the corn. It was planed in the form of random blocks with four repetitions. Procedures 1
and 2 included spraying before emergence and hoeing with drawn hoeing machine;
procedure 3 was spaying before and after emergence, procedures 4 and 5 included
hoeing with PTO driven hoeing machine. With this experiment, we were trying to find
weediness, yield and corn moisture with different procedures. According to the method
of weighing the weeds, weediness was the least with procedure 3. The largest weediness
was with the procedures 4 and 5. Weediness was smaller in the hoed and larger in
nonhoed area. The largest yield of dry corn was with the procedure 3, the smallest with
procedure 4. With the other procedures yield was smaller, because of the larger
weediness in the nonhoed area. The smallest percentage of corn moisture was with the
procedure 3, the largest was with the procedure 5. The smallest percentage of corn
moisture was with the procedure 3, because the weediness was the smallest. U 2003 godini na oglednom polju Biotehničkog fakulteta u Ljubljani urađen je
poljski ogled sa pet potupaka mehaničke i hemijske i samo hemijskog načina nege
kukuruza. Osnovan je kao slučajni blok sa četiri ponavljanja. U postupak 1 i 2 bila je
uključena zaštita pre nicanja, i kultivacija za rotacionim odnosno vučenim kultivatorom.
U postupku 3 bila je zaštita pre i posle nicanja, a u postupku 4 i 5 bila je uključena
kultivacija za rotacionim, odnosno vučenim kultivatorom. U tim ogledima posmatrana
je: zakorovljenost, prinos i vlažnost zrna kukuruza. Zakorovljenost je određena po
metodi merenja težine korova. Po ovoj metodi najmanja je bila zakorovljenost u
postupku 3, a najveća u postupcima 4 i 5. Zakorovljenost je bila veća u nekultiviranom
pojasu i manja u kultiviranom pojasu. Najveći prinos suhog zrna sa 14% vlage je bio kod
postupka 3. Najmanji prinos je kod postupka 4. Najmanji % vlage je bio kod postupka 3,
a najveći kod postupka 5. Kod postupka 3 bio je % vlage najmanji, jer je bila
zakorovljenost najmanja.
