THE EFFECT OF PREPARATIONS ALBITE, IMMUNOTSITOFIT AND ECOGEL ON THE YIELD OF APPLE CULTIVARS ‘EARLY RED’ AND ‘RED CHIEF’ IN THE CONDITIONS OF ABKHAZIA

In connection with the trends that have been developed in recent decades towards ecologized food production, as well as in order to reduce the pesticide load on the agrocenosis, plant immunity inducers applications are being relevantly researched. Albite, Immunotsitofit and Ecogel preparations applied in apple trees agrocenoses (‘Red Chief’ and ‘Early Red’ cultivars) increased the yield of apple trees four times in the spring and summer period in comparison with the control and production processing. Plant immunity inducers influenced the fruits weight specifically for each cultivar. On scab-susceptible cultivar ‘Early Red’, the best indicators were consistently obtained when applying Ecogel (an increase was 6.9– 36.7 % compared to the standard), and on the relatively resistant cultivar ‘Red Chief’, Albite was distinguished among plant immunity inducers (an increase in fruits weight was 4.7–9.5 %). Plant immunity inducers increased the yield of the investigated apple cultivars by 13.9–46.8 % compared to the production processing of apple plantations.
