    CERCETĂRI PRIVIND ACȚIUNEA UNOR FERTILIZANȚI ORGANICI ASUPRA CREŞTERII ŞI PRODUCTIVITĂȚII LA ALUN
    (CEP USM, 2024) Griţcan, Sava; Dadu, Zinaida; Polihovici, Lidia
    The paper presents the results of the research carried out for the first time on the hazelnut culture regarding the fertilization with Orgazot and Grinex applied in the soil to the projection of the crown of the trees.Fertilizers improved the nutrient regime of the soil, increased the content of nitrogen, phosphorus and potassium in the leaves, which favored the accumulation of chlorophyll pigments (chlorophyll A, B and carotenoids), increased the growth of shoots and foliar surface of the leaves.The hazelnut harvest increased by 13% after the application of Grinex fertilizer and by 12%after Orgazot.

    EFICACITATEA FERTILIZANTULUI FOLIAR –REACOM PLUS
    (CE UASM, 2013-09-27) Grițcan, Sava; Dadu, Zinaida; Polihovici, Lidia; Crivaia, Parascovia; Nagacevschi, Tatiana
    The article contains the results of a 2 year study of biochemical composition of apple fruits grown with the use of water-soluble fertilizers as well as of integrated products. It was established that weather conditions influenced the content of monosahara, sucrose separately and less their amount together. The content of dry substances and vitamin "C" remains unchanged. Application of fertilizers on tree development phases has a positive influence on biochemical composition of fruits. It was researched the comparative efficiency of foliar treatment of apple trees with the water-soluble complex fertilizer (Reacom Plus, Fosmex) as well as fertilizers containing nitrogen applied by installments on the background of fertilizers with phosphorus and potassium. It was established that the physiological state of the apple trees improved, the apple harvest increased and duration of fruits storage enhanced.
