This experiment was part of a long term tillage trial designed to examine the effect of various tillage systems on the yield of wheat on a range of agricultural soils in Western Australia. A subset of results from the main experiment is presented here.This report describes the distribution of extractable P, extractable K, total N, organic C, and pH at 6 depths in the soil from 6 locations; Wongan Hills, Merredin (H) (calcic, red-brown earth), Avondale, Merredin (L) (acid, yellow earth), Esperance and Mt Barker. Three tillage systems (conventional cultivation, direct drilled with a combine, direct drilled with a triple …

Conclusions about the geographic and climatic limitations to the economic production of some pulse species in Western Australia cannot be too definite after only two years of gathering data. The yield results confirm the superior adaptation of field pea and narrow-leaf lupin over the faba bean, chickpea, narbonne bean and lentil. In 1987, a relationship was found within specific crop cultivars / accessions, between seed yield and the spring (September + October) rainfall. It is expected that soil type will influence the yield response through variations in moisture retention capacity, fertility and root penetration. Any relationship between yield and environmental …
