ASSESSMENT OF AGROMETEOROLOGICAL FACTORS ON YIELD OF PEACH CULTIVARS IN RUSSIAN HUMID SUBPROPICS USING MATHEMATICAL MODELING METHOD

Peach fruit is much demanded worldwide. The success of its cultivation depends on the optimal plant placement of all the huge biodiversity considering the cultivar demands. The northern boundary of the peach cultivation passes through the Kiev-Kharkov-Rostov-on-Don, Maikop, Nalchik, Grozny, Astrakhan (Witkowski, 2003). However, because of extreme temperatures there are almost no suitable areas for Peach crop cultivation in these borderlands, in the Krasnodar and the Stavropol regions. From the other hand, extreme temperatures for peach cultivation in the humid Russian subtropics were not observed. Spring frosts till -5 ° C were observed in 2004, 2014. However, the cultivar productivity in the region influenced by the duration of low temperatures (7,2 ° C and below) that were observed from December to March. The amount of low temperatures for each cultivar was established using the highest coefficient of yield determination, depending on the temperature, amount of precipitation and the "cooling unit." The yield of peach cultivars is closely linked with the abovementioned agro-climatic conditions during the flowering period. Paired correlation coefficients of yield with precipitation and with temperatures (for most cultivars) were negative, and since they are unregulated value, the flowering phase is crucial for peach culture in the Russian subtropics
