Strains of O. compressus which originate from Paros in southern Greece were the earliest flowering serradellas tested. They consistently produced amongst the highest seed yields, are relatively hard-seeded and are worthy of further investigation for deep sands and very acid soils in low rainfall areas. Monthly applications of nitrogenous fertilizer about doubled the herbage yields of serradella in winter.

Trends In Wheat Protein/Yield Relationships, G B. Crosbie, Harry Fisher, Bryan Whan

Journal of the Department of Agriculture, Western Australia, Series 4

The major concern of wheat breeders in WesternAustralia has been to increase grain yield while maintaining quality at an acceptable level. There has been no concious effort to select for protein content. It is of interrest, therefore, to compare the relationship between yield and protein of varieties which have been prominent in Western Australia at various times, to see what effects yield increases have had on protein content and the extent of any variation which might exist.

The water-holding capacity of these soils, and their location in a low rainfall area combine to make them marginal for producing grain. In contrast to sowing wheat on ley pasture, mechanically fallowing the year before planting markedly improved grain yields by 1.3 to 4 times.
