About 21-year hale cyclic signature in agriculture complement those in biomedicine.
Data on total cultivated area and total production of wheat and rye, barley and two-row barley, corn, soya and sunflower in Romania (1968-2000) are re-analyzed from the viewpoint of chronomics. An about 10.7-year component is detected with borderline statistical significance. A 3-component model consisting of cosine curves, with periods of 3.62, 2.48 and 2.15 years, accounts for 27% of the overall variability. Transdisciplinary chronomics is advocated to systematically map predictable dynamics in agriculture such as Hale-like cycles in corn and soja and their interactions with chronomes of external environmental factors.
