RESEARCHES REGARDING THE INFLUENCE OF FERTILIZATION ON THE FLOWER YIELD OF TAGETES SP. ( FRENCH MARYOLD) PUBLISHEDIonică Prohab, Ioan Borcean None
In the paper are presented the results of the research done on the moderate gleic alluvial soil from Belinţ area obtained by differentiated fertilization for Tagetes tenuifolia, Tagetes erecta, and Tagetes patula, the yellow, orange and nana types.The highest yield was that of 1700 kg/ha liguled dry flowers and was obtained for Tagetes erecta.The yield of liguled dry flowers was increased by 8% by doubling the doses of phosphorous from P 40 to P 8 . The nitrogen based fertilizers, N 34 – N 128 , led to increased yields in the studied areas. Depending on the doses used, the increase in yield was between 2% and 17%.
