The Effect of Foliar Spray Treatments with Various Biostimulants and Fertilisers on the Growth of M.9 Rootstock Stoolings

An experiment was conducted to compare the effect of applying half a dose mineral fertiliser combined with foliar treatment four biostimulants and two fertilisers in relation full fertiliser. The M.9 rootstock stoolings were sprayed times during their growth. Each year experiment, height, diameter, fresh weight leaves leaf surface area all measured. efficiency rootstocks from one mother plant assessed. Some parameters physiological processes as well content micro- macronutrients also research results showed that reduced did not significantly decrease growth stoolings. treatments, especially Bioamino Plant Bispeed, resulted higher larger biostimulant same or better than those control plants. After application fertilisers, usually control. lower most plants (N, K Ca). only exception magnesium after phosphorus biostimulants. Aminoplant Bispeed increased accumulation iron leaves, whereas Basfoliar 6-12-6 zinc copper
