The aim of this study was to analyse the spatial variation of blooming, yield and quality parameters, in an apple orchard, by using precision agriculture tools. This study is a preliminary step in order to create management zones, to take the management decisions and made the evaluation of the applied practices. The study was conducted in the Research and Development Station for Pomology Voinesti, Dambovita, on the 0.9 ha orchard. The orchard consists in Florina apple trees and Generos pollinator. The surface was mapped with GPS and the yield of each tree was manually harvested and weighed. Apple quality was evaluated in terms of: firmness, soluble solid content, juice pH. Also, in spring was determined the number of flowers/tree and the exact period of flowering. The interpolated maps were created using Surfer 8 software and the correlations between yield and quality have been established; some quality characteristics are negatively correlated with yield, like firmness.

Liquid precipitation that freezes on contact with the surface of the underlying components represent a major risk meteorological phenomena affecting, among other things, the high proportion, forest vegetation. The phenomen occurs with a relatively high frequency, every few years, depending on specific mechanisms aggregation on atmospheric physics, needed to its genesis. Affected areas suffer significant changes in structure and composition of forest vegetation. Such a phenomen it was in the first decade of December 2014 on the northern slopes Persani Mountains and it affects an area of 2691.6 hectares of the Măieruş Forest Dept., in Brasov county, resulting 1.84486 million lei ( equivalent to approx. 412,000 euros) damages. Reducing the negative effects on the environment depends on how the administration made the harvesting of downed timber and reforestation of affected areas.
