Long Term Effects Of Direct Drilling And Conventional Cultivation On The Distribution Of Nutrients And Organic C In Soils Of South Western Australia, P F. White, R K. Belford, A D. Robson, N D. Delroy, R J. Jarvis
Division of Plant Research : Technical Report Series
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 …
Evalution Of Grain Legumes For Wheatbelt Rotations In Western Australia 1986 -1987, G H. Walton
Evalution Of Grain Legumes For Wheatbelt Rotations In Western Australia 1986 -1987, G H. Walton
Division of Plant Research : Technical Report Series
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 …

Trial 89AB12
Great Southern Agricultural Institute - Paddock B15
This trial was of similar design to the single row evaluation, except four replications and pesticide treatments were also included.
However the trial had to be abandoned due to severe phytotoxic responses seen in the medics due to repeated spraying of 'Lorsban' (used at recommended rates).
Intended to repeat this work in 1990, bulk seed where possible and to eventually assess these lines, under such conditions, in large plots.

Trial 89NA61
Location: Duranillin
In this site we would expect a very large response (40 to 50% ) to phosphorus.
History:
The site was chosen because of the patchy and poor pasture production. The poor areas tend to have more suckling clover than the good areas. The pasture was legume dominant.
Treatments were applied on April 16, 1989.
