COMMENTS 1. No insect problems experienced and broadleaf weeds effectively controlled by spraying. Septoria· leaf spot incidence insufficient to affect yields. 2. Little effect of time of planting on either total dry matter or grain yield. Crop received about 70% of the average May-October rainfall with a very dry September-October. Perhaps the distribution of rainfall allowed a similar pattern of water use, and total water use by each planting time. 3. There is probably a significant effect of Nitrogen regime on grain yield. Osmocote (N3) consistently yielded more than either single (N1) or repeated (N2) dressings of Agran 34:0. The …

Fallow Re-Assessment, D Tennant

Experimental Summaries - Plant Research

Fallow re-assessment. I. 72M29. Location - Merredin Research Station II. Other fallow results. As part of the fallow re-assessment project, a study was made of results from all trials done since the early 1920's which either compared fallow with non fallow or examined other aspects of fallowing. Analysis of these data has led to an update of some of the rainfall - soil water storage - yield relationships presented in previous reports. On the basis of these rainfall-yield relationships and of relevant rainfall statistics we can make an assessment of the probable value of fallow at different locations; Merredin; Chapman, …

Cereal, Pasture Legume And Water Supply Prospects At Forrestania : Results Of Experimental Work East Of Hyden, Western Australia, T E. Mcdowell, M G. Mason, J W. Gartrell, William J. Toms, I A F Laing

Technical Bulletins

The agricultural potential of the Forrestania area appears at least equal to that of much of the settled eastern wheatbelt. The scrubplain soils of the Forrestania area have an average yield potential of at least 1 000 kg/ha wheat and carrying capacity of 1.8 to 3.7 sheep per hectare on improved pastures. The use of clover ley rotations would maintain these levels of potential yield. Partial crop failures caused by adverse seasonal conditions could be expected 10 years in every 100.

(1) Yield assessments have continued similar to those used in 1977 and 1978. Essentially, plants with symptoms typical of BYDV are marked in the early spring as well as a similar number without symptoms. Yield differences were obtained both for Clipper Barley and an oats variety. (2) Two pilot experiments using viruliferous aphids were carried out at Mount Barker (79MT20) and at South Perth · (79PE13). Both Rhopalosiphum padi and R. maidis were used. Infection at Mt Barker failed, and therefore no data is presented. The Perth experiment was planted on August 31, 1979. The original plan was to have …

Soil Salinity In Western Australia : A Summary, T C. Stoneman

Soil salinity problems have long been recognised in Western Australia. The earliest published explanation in 1924 suggested that removing native vegetation increased stream salinity, and this basic cause has been confirmed by many studies since.
