【 摘 要 】

Due to the big importance of potato cultures as food source worldwide, the phytosanitary protection of thisvegetal crop is an important component of all managerial practices. In this context, we mention Alternaria solaniSorauer fungus attack as major threat in wet climatic conditions. The aim of our study is to emphasize the role ofbiostatistics in analyzing results of alternariosis control in potato cultures maintained in climatic conditions specific toTransylvanian Plane, which receive mineral a fertilization, and treated with specific phytosanitary products. Abifactorial trial (fertilization, treatment, 3 x 2) was installed in a private farm located in Poienii village with variants:control with no fertilization and no phytosanitary treatment (V1), fertilized with compost and treated with Alcupral 50PU (V2), and fertilized with N50P60K80 and treated with Alcupral 50 PU (V3). The attack degrees were weekly recordedduring April up to September 2014. The climatic parameters were monitored with an automatic measuring station. STATISTICA 7.0 v. programme was implemented in order to assure the basis of biostatistical approach. Theimplementation of biostatistical tools demonstrate the importance of using this method, due to synthetic and accurateresults. They demonstrate the superiority of treatment with Alcupral 50 PU in cultures fertilized with mineral fertilizer N50P60K80
