The irrigated brown meadow soils of the Ararat valley are poor in humus content and other important plant required nutrients; hence, the application of scientifically justified quantities of the fertilizers becomes a priority measure. Considering the afore stated fact, the effect of various fertilizers’ combinations (N; NP; NPK; NPK + complexon via foliar feeding, thrice) on the plant growth, yield capacity and its quality has been studied. The best result has been recorded in the option of N120P120K120+complexon. The fruit quality has also improved: the content of dry matters and sugars has increased, while the nitrate content has decreased.
