ABSTRACT
The aim of the present research was to determine the effect of drip irrigation on the activity of enzymes (rhodanese and arylsulphatase) participating at cycling sulphur in soil and content of total sulphur and sulphate (VI) in soil under crops cup plant. The research material was derived from an experiment located at Kruszyn Krajeński in the vicinity of Bydgoszcz. The main factor of the
experiment was irrigation at following variants: O – without irrigation (control plots), D – with drip irrigation. The plant material was made up by plants seedlings from micropropagation. The amount of sulphur available for plants, in the soil investigated for control plots was, on average, 7.62 mg·kg-1 and for the irrigation plots it was similar 5.88 mg·kg-1, which, according to the soil richness with sulphur S-SO42- classifies it as the soil of its average content and growing cereals requires supplementary fertilisation with sulphur.
There was shown a high sensitivity of arylsulphatase on the changes in soil moisture and a greater stability in the activity of rhodanese on that factor.
Key words: arylsulphatase, cup plant, micropropagation, rhodanese, drip irrigation.
