Nutritive Values Of Russian Wildrye, Crested Wheatgrass, And Intermediate Wheatgrass Grazed By Cattle On Utah Foothill Ranges, George W. Mitchell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A comparative index to digestible nutrients was established for Russian wildrye, crested wheatgrass, and intermediate wheatgrass seeded on foothill areas of Utah. The nutritive values of these grasses were compared by the lignin ratio method, the chlorophyllan ratio method, and the in vivo rumen bag process.

Average digestion coefficients computed by the lignin ratio method for dry matter, ether extract, cellulose, and gross energy were highest for intermediate wheatgrass. Protein was more digestible for Russian wildrye. Digestible energy was adequate in all species to meet requirements for late lactation.

Results from the chlorophyllan ratio method were excessively high and were …

Quantitative Evaluation Of Saponin Content In Du Puits Alfalfa Foliage (Medicago Sativa L.) With Trichoderma, Wang Li-Chun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Selections in Du Puits alfalfa (Medicago sativa L. ) were evaluated for saponin content. The data obtained from the Trichoderma bioassay were converted to saponin values by regressions and standard curves. It was necessary to adjust the concentration of alfalfa extract in the bioassay so that the saponin content in alfalfa was estimated in that portion of the curve showing a marked response to saponin. A different regression was established for each group of low and high saponin plants of Du Puits alfalfa. The standard curve prepared with extract of Du Puits alfalfa used on the basis of its …

High Stocking Rate On Kikuyu Dairy Pasture : Progress Report On Grazing Trials On Kikuyu-Sub. Clover Pasture At Denmark Research Station, F E. Ryan

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

KIKUYU is one of the most valuable pasture plants on dairy farms in the South-West of Western Australia.

It combines well with subterranean clover and ryegrass if heavily stocked, and pastures managed in this way can be cut for legume-grass hay in the spring. However, relatively little is known of its carrying capacity or potential for production under grazing.

Higher Stocking Rates For Cattle On Irrigated Pasture : A Report From Wokalup Research Station, Maurice C. Cullity

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

The possibility that higher cattle stocking rates than those commonly used could be economical was suggested by the results of a stocking rate trial at Wokalup Research Station

More Butterfat Per Acre At Denmark Research Station, Department Of Agriculture, Western Australia

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

STOCKING rates on dairy farms are generally too low and can be substantially increased, but unfortunately there is no satisfactory measurement to indicate the potential of a particular pasture or environment.

A trial carried out on Denmark Research Station in 1966-67, to obtain information on carrying capacity of a dryland kikuyu-subterranean clover pasture.

A Comparison Of Methods Of Urea Application At Ajana, M G. Mason, R. J. Parkin, H. Patrick

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

Compared with urea application separate from the seed, urea mixed with wheat seed delayed and reduced wheat germination, and reduced wheat yields, especially at high rates of urea.

Yields were higher where the urea was topdressed immediately before seeding than where it was top-dressed either immediately after, or two weeks after seeding.

Fertiliser Recommendations For Apple Trees, N H. Shorter, J. E. L. Cripps

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

THE increased use of irrigation and chemical thinning in apple orchards and the planting of trees in light soils have resulted in responses to regular fertiliser dressings.
