Studies on the primary production of the potato field

, : Studies on the primary production of the potato field. Ekologia Polska 21(50): 813-826

The net primary production of 2 potato fields, the 1st located on the E. side of a shelter belt and planted with Flora in 1969, the 2nd on the W. side and planted with Uran in 1970, was estimated on the basis of the amounts of biomass produced by the crop and weeds. Values ranged from 961.5 to 1086.3 g DM/m2. The production was the same on each field with the exception of a 10-m belt adjoining the shelter belt.
