Weed Control Measures in Maise

Abstract

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.
