R. aPot experiments with various sulphur-containing compounds for rye grass and oats.h[electronic resource] c1978 aVarious organic sulphur compounds were compared with gypsum as sources of sulphur, in an experiment with annual rye grass in Spliagrirtrn peat, and one with oats grown in quartz sand. Without sulphur application in any form, both species showed obvious sulphur deficiency, though expressed in different ways. The yields and total content of S and cystine in the plants were lower than with adequate sulphur supply. Furthermore, the amino acid spectrum and the content of certain other components of crude protein appeared abnormal in rye grass. Choline sulphate and taurinc proved approximately equivalent to gypsum as sources of sulphur for both plant spccics. Cystine appeared inferior in the rye grass experiment. To oats, methionine placcd itself in a unique position, with high methionine and total S content in the plants. This indicates that the plants absorb sulphur quite readily from this aniino acid. The cause of the low yield at this treatment remains still an open question. aDry matter content aForage yield aOrganic compounds aSulfur fertilizers aAdubação aEnxofre aLolium Perenne aPastagem aFeed grasses1 aSORTEBERG, A.1 aODELIEN, M. tAgricultural Scandinavicagv. 28, n. 3, p. 293-297, 1978.
