Effects of using different soil tillage systems and treatments of herbicides in production of maize

Abstract

In this paper influence of two heavy mechanical type tillage systems: A - conventional tillage system and B - conservation tillage system is analyzed, and two different treatments of herbicides on yield of maize as well. The experiments are carried on production fields of 'Institutes for maize - Zemun Polje', during 2008/09 years. The focus of this research, among other effects, is on maize yield, as relevant parameter of efficiency of plant production. Right choice of soil tillage system and treatments of herbicides are key point for improvement of plant production, especially for grain yield aspects. Soil tillage system B in comparation with soil tillage system A is 10% more efficient. Treatment with herbicides 1 in comparation with treatment with herbicides 2 is 9,42% more efficient. Combining these two variable parameters (soil tillage systems and treatment of herbicides), the most efficient is model B+1, with grain yield increased up to 18,7%.

U radu je analiziran uticaj dva sistema obrade zemljišta teškog mehaničkog sastava: A - konvencionalnog i B - konzervacijskog, kao i primene dva različita tretmana herbicida na prinos merkantilnog kukuruza. Ogledi su izvedeni na proizvodnim površinama Instituta za kukuruz iz Zemun Polja, tokom 2008/09 godine. Akcenat istraživanja je, pored ostalih pratećih efekata, usmeren na prinos kukuruza kao relevantnog pokazatelja efikasnosti biljne proizvodnje. Pravilan izbor sistema obrade zemljišta i tretmana herbicidima svakako može unaprediti proizvodnju, naročito sa aspekta ostvarenog prinosa gajene kulture. Povećanje prinosa uslovljen modelom obrade je u korist modela B, veći za 10%. Povećanje prinosa uslovljen tretmanom herbicida je u korist tretmana 1, veći za 9,42%. Sa dejstvom ove dve agrotehničke mere, kao najoptimalnija kombinacija pokazao se model B+1, sa združenim efektom povećanja prinosa do 18,7% u odnosu na druge modele.
