Abstract:
Global warming is currently considered a "planetary cataclysm" in full swing; it is the worst climate risk on Earth, whose causes, still unknown exactly, create important contradictions in the scientific world and among policy and economic decision-makers on a global scale. This article provides an analysis of research conducted in 2016-2019, with data obtained by monitoring the influence of climatic factors on soil moisture and productivity of field crops agroecosystems from Plop locality, Dondușeni district, GȚ "Agro-Panfil". The authors underline the role and the great importance of the study conducted on climate change by assessment of climatic conditions (temperature and precipitation) through the HOBO station, providing us with data and concrete examples. This paper also describes agroecosystems were monitored practically from sowing to harvesting and post-harvesting throughout the agricultural year through the Station "HOBO - 01102025". Were investigated main agricultural ecosystems (autumn wheat, autumn barley, soybeans, rape, alfalfa) characteristic for the North area of the country. The characteristic of the climatic conditions of the agricultural years 2016-2019 for the researched agroecosystems are presented in figures 5 - 7. Research has shown that climatic conditions have influenced the harvest of field crops. The harvest structure for some research variants is presented in fig. 9 compared to the harvest obtained on the territory of the Republic of Moldova in fig. 8. The average harvest for autumn wheat (4.8 t/ha) and autumn barley (6 t/ha) was high, maize grains - very high (9 t/ha), sunflower (2.4 t/ha), rape (3.3 t/ha), sugar beet (60 t/ha), soybeans (1.8 t/ha) - low.
