In the three experiments reported, the selenium content of pastures was shown to be substantially affected by applications of sulphate fertilizer. Where pasture yields responded to sulphur topdressing, selenium levels in the legumes present were reduced by as much as 50 per cent due largely to yield dilution effects. On a second site, where pasture responses to sulphur were not obtained, selenium levels were also depressed, in this case indicating the existence of an antagonism between sulphur and selenium. A subsequent nutrient solution culture experiment indicated that an antagonism existed between sulphate and both selenate and selenite forms, with the effects being much stronger in the case of the selenate. The implications in animal production of the effects of applied sulphur on pasture selenium levels and of the associated increases in pasture sulphur levels are discussed.

`Vates' collard (Brassica oleracea L. Acephala Group) was more susceptible to tipburn than `Blue Max' or “Heavi Crop' in field and nutrient solution culture experiments. The root system of Vates' was smaller than that of `Blue Max' in all experiments. Because of its smaller root system, `Vates' may be more susceptible to moisture stress than `Blue Max' when grown under high-temperature conditions on sandy soils, thus increasing susceptibility to tipburn. Root system size, however, did not influence Ca accumulation or Ca concentration in the plants. Calcium accumulation rate was higher for `Blue Max' and `Heavi Crop' than for Yates' during the 3rd through the 5th weeks of culture, in a nutrient solution that contained 5 mM Ca. Calcium efficiency ratio (CaER, milligrams of dry matter produced per milligram of Ca in tissue) for young leaves was higher for `Blue Max' and `Heavi Crop' than “for `Vates' when plants were grown with 1 mM Ca, which may partly explain the greater susceptibility of `Vates' to tipburn. `Heavi Crop' had a higher total plant CaER than `Blue Max' when grown with 5 mM Ca.
