Simulation of influence of natural and climatic and agrochemical factors on efficiency and safety of industrial cultivation of large-fruit cranberry in controlled production environment

The analysis of influence of the most significant natural-and-climatic and other factors (the level of soil moisture during periods of active growth of green mass, emergence of sets, berry ripening; the impact of return spring frosts; the quality of mineral fertilizers application; chemical protection of plants on checks from weeds, pests and diseases) on the efficiency and safety of industrial cultivation of large-fruited cranberries in the conditions of changing parameters of the production environment has been carried out. On the basis of logical-and-linguistic approach, a mathematical model of influence of the considered factors on potential biological yield of berries in conditions of changing state of industrial environment has been developed. It has been determined that the most important for the effective functioning of industrial cranberry checks is the factor of “chemical protection of plants”. It has been established that under conditions of meeting the required indicators of water-and-air and thermal modes of soil on the checks in case of non-observance of agro-timing, violation of dosage and uniformity indicators of chemical plant protection products and mineral fertilizers application, the losses of berries can make over 30 % of the yield.
