Abstract
The processing tomato cultivation, like the rest of the outdoor cultivation is very dependent on climatic conditions, an aspect that is accentuated in climates such as the Mediterranean which is characterized by a large inter-annual as well as intra-annual variability.
Weather conditions and trends in the main climatic variables which affect tomato crops, is essential information, taking into account current global warming.
From 11 stations operated by the European Climate Assessment & Data set (ECAD), which is a daily, high-resolution data set of in-situ meteorological observations, daily maximum and minimum temperatures were used to compute the active days (tm>10°C) and the optimal days (25<tm<30°C) in different periods (months and growing season) in the most important areas of processing tomato cultivation in Europe in the last 30 years.
The first objective was to characterize the differences between the cultivation areas and the second and main objective was to analyze the effect of climate change in the duration of the active and optimal harvesting season.
Trend analysis was performed by an ANOVA test, while the trend analysis for the time series was evaluated using Mann-Kendall and trend magnitude was estimated by Sen-Slope methods.
The results obtained have identified significant differences in the duration of optimal and thermally active days in many areas of Europe.
Increasing trends have also been found in the length of the period of optimal temperatures in the years of study.
Consequently, the start of the harvest is expected to be earlier.
