Abstract


Climate conditions in any land area have a direct influence on the productivity level of natural ecosystems and agroecosystems. To assess the yield per area unit, we took into account the amounts of dry matter depending on temperature (10C) and precipitations (1 mm) during vegetation. During the experimental period, the mean annual temperature during vegetation was 9430C, with variations between 7750C (1997) and 1,1750C (2012). This multiannual variation of the thermal constant also influenced the level of dry matter yield per 10C, which ranged between 2.14 kg DM/10C and 9.08 kg DM/10C. As for the amounts of precipitations, dry matter yield varied between 6.02 kg DM/1 mm (2002) and 29.11 kg DM/1 mm (2003).


Keywords
