RESEARCHES REGARDING THE VARIATION OF THE WHEAT PROTEIN CONTENT AND PRODUCTION ACCORDING TO THE CULTIVATION AREA, TO THE WHEAT VARIETY AND TO THE FERTILIZATION PUBLISHEDVasiliki Rousi, Ioan Borcean
In this paper are presented the results obtained in Greece, in the region Aitoloakarnania, on an alluvial soil, and in Romania, in Câmpia Timişului (Timiș Plain), on a typical chernozem. The studied varieties are Gegora and Dio from Greece and Dropia from Romania. In Greece, the fertilization was done with 10 and 20 t manure/ha and in Romania with N 75, P 60 K 60 and N 150 P 60 K 60 . The protein content increased as the fertilizer dose increased. So, in Greece the protein content increased from 13,3% at the reference variant and 14,8% at the Gegora variety, to between 13,6% (Mt) and 14,1% (in the variant fertilized with 20t manure/ha) at the Dio variety and to between 13,0% (Mt) and 13,9% at the Dropia variety. In Romania, the protein content varied between 13,2% (N 0 ) and 14,8% (N 150 ) at Gegora variety, between 12,9% (N 0 ) and 13,9% (N 150 ) at Dio variety and between 12,5% (N 0 ) and 14,1% (N 150 ). The protein average quantity per hectare and according to the fertilization levels was of 566 kg/ha for Dropia variety and of 486 kg/ha for the varieties Gegora and Dio in Romania and of 502 kg/ha for Dropia variety, of 591 kg/ha for Gegora variety and of 573 kg/ha for Dio variety in Greece.
