| Tartalmi kivonat: | The knowledge and application of quantitative and qualitative means of increasing corn production is a major concern of growers and researchers in the field. One of the main factors of increased production in corn is planting dates. Planting at the optimum time favors emergence, growth and development of plants. The purpose of this paper is to analyze the behavior of current corn hybrids at different planting dates, based on a polyfactorial field experience with hybrids of three maturity groups and 4 planting dates. Thus, observations were made during the vegetation period, like: the appreciation of emergences, cold spring resistance, plants condition and uniformity. The yield obtained was analyzed according to planting dates and hybrids. The results highlights the importance of following optimum planting date of corn, which is different depending on: soil temperature, location, soil water reserve, disease and pest pressure, weed pressure, used hybrid, tillage system, etc. The results obtained from the field experience demonstrates the superior production capacity of current hybrids, this is due to the progress in breeding and selection of new corn hybrids. |
