Forage Quality Evaluations Of Twelve Grasses In Relation To Season For Grazing, L. C. Newell, W. J. Moline

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

A study of forage quality in relation to seasonal yield of important perennial forage grasses was initiated to provide information and to promote a better understanding of their best use for grazing. This information should be particularly valuable in planning seasonal use of pure stands or mixtures of grasses.

Results Of The Eighth International Winter Wheat Performance Nursery Grown In 1976, K. D. Wilhelmi, S. L. Kuhr, V. A. Johnson, P. J. Mattern, J. W. Schmidt

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This is the eighth report of results from an International Winter Wheat Performance Nursery (IWWPN) organized in 1968 by the Nebraska Agricultural Experiment Station and the Science and Education Administration (SEA), U.S. Department of Agriculture, under a contract with the Agency for International Development, U.S. Department of State. The Nursery was designed to (1) test the adaptation and stability of winter wheat cultivars in a range of latitudes, daylengths, fertility conditions, water management regimes, and disease complexes; (2) identify superior winter cultivars to serve as recipient genotypes for high protein and high lysine genes, (3) test the degree of expression …

Sulfur Fertilization Of Alfalfa And Corn On The Sandy Soils Of Nebraska, G. W. Rehm

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Objectives of these studies were: 1. To determine the effect of various S fertilizers and rates of S application on the yield of both alfalfa and corn grown on sandy soils. 2. To determine the residual effects of a single application of S fertilizer on the production of alfalfa. 3. To measure the influence of S fertilizers and the rate of S applied on the S content of corn and alfalfa tissue and S uptake by these two crops. 4. To develop a soil testing procedure which accurately predicts the requirement for the application of S fertilizers to alfalfa and …

Effects Of Row Width And Seeding Rate On Yield And Other Agronomic Characteristics Of Three Soybean Cultivars, Russell Kithcart

Masters Theses & Specialist Projects

Soybeans have traditionally been grown in rows wide enough to allow mechanical cultivation and to increase lodging resistance. Improved cultivars and herbicides have permitted farmers to obtain yield advantages from narrower rows. The growth response of soybeans to variations in row width and seeding rates depends upon the cultivar and geographic location.

“Williams,” “Mitchell,” and “Essex” cultivars were planted at row widths of 18, 36, 54, and 72cm. at seeding rates of 33, 67, 100 and 134 kg/ha in multi-row plots. Data were collected from each plot for seed yield, lodging, plant height, height of lowest pod, seed and population …

Results Of The First High Protein-High Lysine Wheat Observation Nursery Grown In 1975, K. D. Wilhelmi, S. L. Kuhr, V. A. Johnson, P. J. Mattern

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This is the first report of results from a high protein-high lysine observation (HP-HL) nursery organized in 1974 by the Nebraska Agricultural Experiment Station and the Agricultural Research Service, U.S. Department of Agriculture, under a contract with the Agency for International Development, U.S. Department of State. Primary objectives of this nursery are to: (1) Systematically provide breeders and cooperators with superior genetic germplasm for elevated levels of protein and/or lysine. (2) Test the degree of expression of the high protein and high lysine traits in a diverse array of environments.

Zinc Fertilization Of Corn In Kentucky, W. W. Frye, H. F. Miller, Lloyd W. Murdock, D. E. Peaslee

Agronomy Notes

Of the agronomic crops, corn is especially sensitive to zinc deficiency. The major symptom of zinc deficiency in corn is broad white stripes in the leaves at or near the growing point in the early growth stages of the plant. It has been referred to as "white bud" disease because of the characteristic whitish area on one or both sides of the midrib near the base of new leaves. It can be seen as a new leaf unfolds from the whorl. Growth is stunted resulting in shorter than normal internodes. The pith of the stalk may become darkened at the …

Soil And Plant Analysis : A Guide To Fertilizer Usage, Walter Jacob Cox

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

Soil and plant analysis can be used to identify problems in soils, diagnose nutrient deficiencies and as a guide to fertiliser usage.

Soil testing is particularily useful where large amounts of phosphorus and potassium are leached or removed from the paddock in hay or silage.

Actual rates of fertiliser can only be recommended from soil testing and only in conjunction with additional biological and economic information.

Producing 20-Month Old Beef Steers Off Annual Pasture, K D. Greathead, D. J. Barker, W. J. Ryan

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

A recent Mt Barker experiment compared two systems of fodder conservation with continuous grazing, using two types of steers, at three stocking rates. Year-round performance, carcass composition, and resulting costs and returns per hectare were assessed.

Production per hectare was greatest from crossbred steers at the intermediate stocking rate with either type of fodder conservation.

Response Of Different Crops To Various Rates Of Furnace Ash Applied As A Soil Amendment, Lloyd W. Murdock, George Everette

Agronomy Notes

Furnace ash from coal fired electrical generating steam plants has increased greatly in the last decade with the increased demand for electricity and increased restrictions on air pollution. The large volumes of ash are presenting disposal and containment problems for management of electrical generating plants. Property adjacent to the generating plants has been exposed to fly ash settling from the smoke stacks and ash over flowing from holding structures. The effects of the material on the land and its production are unknown and concern property owners.

Tincurrin : A New Biscuit Wheat, J T. Reeves, H. M. Fisher, G. B. Crosbie

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

Although a demand has existed both locally and overseas for soft wheat suitable for biscuits, cakes and various confectioneries, production has been very limited.

In 1978 farmers in the soft wheat area will be able to grow the higher yielding variety Tincurrin.

It is recommended for general sowing to replace all varieties grown at present in the soft wheat areas as defined.Exceptions may prevail in areas prone to rust snd septoria problems.

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

Sharing of single items of plant between farmers is common in Australian Agriculture but it is quite rare for farmers to amalgamate their holdings and farm them as a single unit.

This article looks at the advantages of syndicate farming. It is based on a study of four whole farm syndicates in the Wimmera of Victoria.

Wesreo : A Blackleg Resistant Rapeseed, N N. Roy

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

A new rapeseed variety, Wesreo, has recently been released after an unusually rapid and successful breeding programme by the Department of Agriculture.

Trials Indicate Best Lupin Seeding Rates, G H. Walton

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

Trials on the seeding rate of lupins have shown that for most crops, at least 80kg of seed per hectare gives best yields. However the yields varied considerably, and in higher yielding situations, lower seeding rates were better.

Progress In Clover Scorch Research, A Bokor, D. L. Chatel, D. A. Nicholas

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

Considerable progress has been made with the clover scorch problem since the devastation of the 971 epidemic when intensive research began.

Over 2000 varieties and crossbreds of subterranean clover from various collections have been screened for resistance resulting in the release of the first resistant clover, Esperance, this year.

Benefits of fungicidal spraying have been demonstrated and low cost spraying programmes for grazed pastures, and seed and hay crops are under field investigation.
