QUANTIFYING SOME PRODUCTIVITY ELEMENTS IN REACHING YIELDING POTENTIAL IN SIX PIONEER MAIZE HYBRIDS UNDER THE IMAPCT OF SOWING DENSITY IN THE SOIL AND CLIMATE CONDITIONS OF THE ARADULUI PLAIN (SEMLAC, ARAD COUNTY) PUBLISHED

Sorin Luca, Valeriu Tabără
Of world production of corn about 6 to 10% is used in various industries. Thus maize is processed wet, dry and fermentative. By all these methods, from corn to obtain some basic products that are used to obtain more than 3500 products with uses in a man but also in animal nutrition. Variability of chemical composition of maize grain is given by the combined actions of the following factors: soil, climate, agricultural technique, local conditions of nutrition, conditioning and storage. The present study proposes to examine the production quality hybrid maize seeds from 6 to determine optimum sowing density. Experience was located on a typical mold soil in the territory Plain Arad, Şemlac. In terms of physical characteristics, soil that was placed experience, providing favorable conditions for growing the plant Zea mays. Bifactorial experience is that factor analysis, factor I is the biological material certified corn hybrids, Pioneer brand: Pr37M34, Pr36R10, Pr37N01, Florencia, Pr35F38, Pr35T06 - hybrids of groups FAO 450-500, and factor II is given sowing densities: 40,000 plants / ha, 55,000 plants / ha, 70,000 plants / ha. The main physico indicators of the 6 grains of corn hybrids were determined in laboratory discipline Plant Growing: "Testing of the seed and plant material”.The Correlations were established between the physical evidence and density studied hybrids of maize plants. As the sowing density of three variants applied hybrids take the study as influencing indices of maize, but differently. Results of this study are part of a doctoral program, with the theme: "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.
