Autotrophic plants are significant for unique ability ? to produce bioproduction i.e. biological and agronomical yield in photosynthesis process. However yield amount is eliminant by interaction of plant genetic potential and external environmental factors. In submitted work is analyzed mathematical-statistical relation between botanical yield of Vitis vinifera, variety Furmit and characteristics of energetic and water balance, which is expressed by average temperature and precipitation total amount for months of vegetation period in years 2001 -2007 in Tokay vineyard region. Biological but also agronomical grapes yield is resultant of genetic and biological potential and also external environmental factors. For the grape is elementary limiting factor for organic mass production the air temperature, which influences such vital function as transpiration, photosynthesis, nutrient income, breathing and so on. In this connection is the most used temperature characteristic the thermal vegetation constant i.e. the sum of active temperatures of air for the main vegetation period (T≥10.0?C). From the characteristics of water regime is the most used the total atmospheric precipitation. On the base of analytic relation between cumulative sum of air temperature (∑T in ?C), total precipitation (P in mm) of a grape phytomass production (Uf in kg.m-2) was created agroclimatical diagram of grape production. From diagram is possible in random part of vegetation determinate the phytomass yield and to its, according coefficient K=0,588 the agronomical yield (grapes). Consequently there was determinated the model of phytomass and saccharides production with using mathematical-statistical analyse according the program of non-linear correlation and multiple linear regression the influence of temperature and precipitation to production process.
