Worldwide, maize ranks 3 rd from the point of view of the areas cultivated with maize – after wheat and rice – and 1 st from the point of view of the production. Due to the large areas cultuivated with maize and particularly due to the maize prodcutions, mankind largely depends on maize to feed. Due to the chemical composition of its component parts, maize is both a absic food for humans and a basic feed for animals as well as a valuable raw matetr for industry. The importance of corn as the crop is clear from this plant that uses it has. Thus, maize grain used to feed both people and animals to obtain oil. In human nutrition, by grinding dried beans are obtained: corn flour, corn flakes, baby food, milk etc artificially. The wet milling (grain with embryo), we obtain, in addition to the products listed and rich in fructose syrup (for diabetics), beer, coffee substitutes, etc. coated glazed pastes. The different treatments after wet milling are obtained: starch, glucose, dextrose, whiskey, drug. In forage nutritive value of maize is 1.17 to 1.30 units for 1 kg grain nutrition. The cobs are obtained : furfural, fodder for ruminants, soaps, vitamins are used as fuel . The world production of oil 2% is obtained from corn. Green plant is used as feed for dairy cattle feed. Expansion in culture is due to nutrition and special features The main goal of this paper is to determine optimal planting density in six maize hybrids aiming at obtaining optimal production quality indices. : "Research on the influence of sowing density on production and its quality from 6 corn hybrids, climatic conditions of Plain Arad" scholarship program funded by the European Social din Pilot Program Fund to support research doctoral scholars, under contract POSDRU/6/1.5/2 USAMVB Timisoara, under the distinguished University Professor Dr. Valeriu Tabară
