Ամփոփում

Investigations carried out in 2017-2019 under dry agricultural conditions at the Hrazdan province of the Kotayk region have disclosed that out of the two tested soil cultivation variants (deep ploughing, single disk harrowing), soil loosening with the single disk harrowing is the most efficient variant for the winter wheat
cultivated in the black soils, while out of the applied technologies (organomineral fertilizers and zeolite), that of the zeolite, manure and N30 applied on the background of P90K90 is the best variant. When applying this variant the soil agro-meliorative properties improve and 55.0 c/ha grain yield is harvested. Thus the mentioned variant is recommended for the introduction in the agricultural production.
