The only difference between the two varietiesproduction was recorded in the unfertilizedvariant, where the Generous exceeded theproduction of Florina variety by 0,28 t/ha,which is a significant difference statisticallyassured being insignificant. Fertilizeradministration has reduced the distancebetween productions, reaching at the dose of 5kg/ha, Florina variety exceeds the production atthe Generous variety, but the differences areinsignificant.Influence of fertilization level on theproduction of apples for the same varietyand level of irrigation, average of the years2008-2011.Under the same conditions of fertilization andirrigation, the reaction was different varieties.Thus, Generous variety obtained yieldincreases in the range of 0,78 t/ha, at doses of2,5 kg/ha to 1,16 t/ha obtained by Florinavariety, up to 4,94 t/ha, achieved growth in adose of 5 kg/ha towards 5,25 t/ha obtained byFlorina variety. This variety has used moreeffectively the fertilization effect. All registeredproduction increases at all graduations used,were very significant.Influence of irrigation level on theproduction of apples for the same varietyand level of fertilization, average of the years2008-2011.Applying irrigation causes very significantproduction increases at all variants studied.Thus, Generous variety obtained yieldincreases in the range of 2,15 t/ha, the norms of2 l/h compared to 1,94 t/ha obtained by Florinavariety, up to 7,40 t/ha, increase made at normof 4,94 t/ha, increase achieved at a dose of 4l/h, compared to 7,10 t/ha,obtained at Florinavariety. Generous variety exploited moreefficiently the effect of irrigation.All registered production increases at allgraduations used were very significant.Influence of variety on the production ofapples for the same level of irrigation andfertilization, average of the years 2008-2011.There are no differences of productionstatistically assured between the varietiesanalyzed, which suggests a production capacityapproximately equal. Overall the yields ofFlorina variety were lower than the Generousvariety. The largest differences in productionwere of 0,43 t/ha and the lowest, of 0,01 t/ha.REFERENCESAtkinson D. 1977.
