The different agro-technical conditions, include three tillage treatments, three levels of N-fertilizer treatments, two levels of plant densities, irrigated and non-irrigated, monoculture maize and maize-winter wheat biculture. The experiment was set up in a split-plot design, as is part of an ongoing long-term polyfactorial experiment at Látókép Research Station, Debrecen, Hungary • Yield ranged from 7.12 tons/ ha to 11.64 tons/ ha. The highest yield was obtained in autumn plowing, 70,000 plants/ ha , 240 N-kg/ ha , irrigated and in maize-winter wheat biculture. • The best performing hybrid was Armagnac followed by Neffel and Renfor respectively. • N-120 kg/ ha was found to be the most economical and environmentally sound level. • Yield of maize was significantly influenced in increasing order by irrigation, hybrid, plant density, forecrop and fertilization. Tillage was not found to have any significant effect on the yield of maize.50enagrotechnical factorscrop yearhybridsDEENK Témalista::Mezőgazdaságtudomány::Talajtan
