IMPLEMENTATION OF MANAGEMENT PRINCIPLES ON GREENHOUSE VEGETABLES NEAR THE CITY OF THESSALONIKI
The aim of this work was to implement the management principles on greenhouse vegetables in Thessaloniki and to estimate the effectiveness on greenhouse crops. For this purpose a questionnaire was composed and filled in by the greenhouse growers (with formal, integrated and biological production) in the area near Thessaloniki. Before visiting the growers, a visit to the Directorate of Rural Development in Thessaloniki took place in order to provide to the research the necessary informations about the greenhouse growers and their reliability. Simultaneously observation tables were filled in which helped the finance results to be extracted. Results testified for greenhouse growers separation and theirs explanation based on growers profile and theirs management ability. Finally, Data Envelopment Analysis (DEA) took place as a method for approximation of estimation of technical efficiency (TE), for greenhouse farms. DEA method is based on influx and efflux of farms and contributed to range greenhouse farms according their efficiency. The results showed that the strategy sets objectives, provides changes, make choices according to the: i). choice of the production method, ii). determination of the production plan, iii). definition of other investments iv). desire of the farmer - trader to have some control over the growing procedures. However, these results can not be generalized, mainly because of the climate differences between cultivation periods and simultaneously the differences on influx and efflux values. In order to be achieved results efficiency a series of experiments with a lot of repetitions been proposed.
