Knowing the relationship between orchards and bio-fertilization practices is needed to develop new production systemswhich bring known benefits and those of economic nature. Bio-fertilization systems applied to varieties of apple (Malusdomestica Borkh.) Vf type are recommended in order to maximize profitability in the apple culture. The purposeof thisstudy (2012-2013) was to calculate bio-fertilization influence on yield (t/ha) of apple varieties with genetic resistance toscab (Vf): 'Topaz', 'Redix', 'Rubinola', 'Goldrush' and economic indicators in the climate conditions of the Ilfov county.Experimental module was arranged by trifactorial type using the subdivided parcels method in three repetitions. At thebase of the economical study the technological files of apple culture/ha was used, determining the following indicators:production costs (lei/ha), net profit (lei/ha) and net profit ratio(%). Significant increases ineconomic indicators between10 and 20% resulted in the experimental variant Naturamin 7,5kg/ha.
