Correlative Models between Balaton (B) and Atrium (E) Wheat Varieties, Nitrogen Doses and their Division in Seini – Maramures, 2009-2010

This study is intended to demonstrate that in the pedoclimatic conditions from Seini – Maramures, some that are not very favorable to the wheat crop, the productivity it can be easily increased by applying a new fertilization management scheme and by using wheat varieties of different categories, but with a great plasticity to biotic and abiotic factors from the research region. To analyze the reaction of Balaton and Atrium wheat varieties at a specific nitrogen management, the method of demonstration plots has been used, with 14 variants of nitrogen fertilization, in different dosages and application phases. Obtained results have been statistically processed. It has been observed that for both varieties the nitrogen fractionation doesn’t bring any increases at low doses (40-60 kg N/ha), but it is very efficient and demonstrated by the correlations performed at high doses (70-120 kg N/ha). Premium and A type wheat varieties, of provenance Austria, have been acclimatized and they can be successfully grown in the Seini area, as illustrated by the obtained yields.
