Abstrakt
Field experiments conducted at the Centre of Estonian Rural Research and Knowledge
evaluated six leguminous green manure crops grown as independent crops within an
organic crop rotation. The pre-incorporation biomass (dry matter t/ha) and the corresponding
plant nutrients (N, C, P, K kg/ha) were determined. The fertilizing value of
green manure was assessed on spring cereals (barley, spring wheat, oats, two varieties
of each) in the year following incorporation, based on the changes in yield, yield quality
and thein contribution to the realizable market value per hectare. The experimental
results showed that all green manure species significantly increased spring cereal yields
per hecatre and improved most of the quality indicators, to an extent that allowed spring
wheat and oats to be marketed as food grain, thereby enabling a higher sale price. Variety
choice was an important factor. Spring wheat and barley responded well to red and
pink clover used as green manure, with yield increases of approximately 60%, while
annual, biennial and perennial legumes sown as green manure had a similar fertilizing
effect on oats, resulting in yield increase of 30–40%.
