Experimental Summaries - Plant Research

Powdery mildew control of grapes with fungicides. Location: Mount Barker Research Station. Black spot and downy mildew of processing peas - 80AL32. Facial eczema investigation. Facial eczema is a recognised myco-toxic disease of grazing stock in New Zealand. It is caused by a fungus Pithomyces chartarum growing on dead litter part of the pasture. The disease has become recognised as a risk to sheep in the Albany Region following reported losses in 1978. A pasture paddock at Cape Riche was sampled weekly by the Animal Division to determine fluctuations in spore numbers of P. chartarum. Comments: The fungus could readily …

Influence Of Planting System On Surface Soil, Physical Conditions And Soil Water Relations, D Tennant

Experimental Summaries - Plant Research

Influence of planting system on surface soil, physical conditions and soil water relations. The availability of soil water for crop use can this way be influenced by planting system. Various aspects of soil water relations were examined in varying detail at three sites - Wongan Hills, Avondale and Merredin, over the 1979 and 1980 growing seasons. Some of this soil water data are presented here. The Department of Agriculture initiated a programme in 1977 to investigate and compare crop performance under several planting systems. This project was part of this programme and had as its objectives: 1. Measurement of soil …

Effects Of No-Tillage Fallow As Compared To Conventional Tillage In A Wheat-Fallow System, C. R. Fenster, G. A. Peterson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The benefits of reducing tillage by use of herbicides for weed control emphasizes why research was started to study a fallow system where all tillage was replaced by herbicides. Wheat planting was then the only soil disturbing operation. Objectives of the research were to compare the effects of no-tillage (chemical), stubble-mulch and plow (bare fallow) systems of fallow on: 1. Grain yield. 2. Grain protein. 3. Residue retention. 4. Soil nitrate-nitrogen accumulation. 5. Soil water accumulations during fallow. Data presented are in the form of a progress report. These experiments will continue.
