1990 Kentucky Winter Annual Legume Variety Test, L. M. Lauriault, Norman L. Taylor, Jimmy C. Henning, W. T. Edmonson

Agronomy Notes

Cover crops are often used in Kentucky following the harvest of row crops such as tobacco, corn, and soybeans. Living cover crops can prevent erosion, reduce leaching of nutrients, and supply grazing, green manure, or a plant cover in which to no-till the following spring.

Bulletin 4133 - Fungal Diseases Of Pasture Legumes In Western Australia, M. J. Barbetti

Bulletins 4000 -

Subterranean clover (Trifolium subterraneum L.) is the most important annual pasture legume in Western Australia, forming the basis of some 6.5 million ha of annual pastures. The success of subterranean clover may be attributed to its ability to increase soil fertility as a consequence of nitrogen fixed, to withstand heavy grazing, to control soil erosion and, with some cultivars, to tolerate waterlogging. Fungal diseases have been a major limitation to the productivity of subterranean clover, affecting both the amount of plant matter and the quantity of seed produced.

Annual medic (Medicago spp., in particular M. polymorpha L.) is also an …

Soil Acidity And Legume Nodulation, J G. Howieson, M. A. Ewing

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

Nitrogen is a basic constituent of protien and is essential to all forms of life. Many agricultural plants are legumes - a group of plants which, in co-operation with specialised soil bacteria, fix their own nitrogen from the air. When the legume dies, the organic matter breaks down anf the nitrogen becomes available to the following crops.

Soil acidity is a major factor limitimg the successful association between legumes and their beneficial soil bacteria in Western Australia.

Agronomy Of Low Alkaloid Lupins - Preliminary Investigations, C M. Francis

Experimental Summaries - Plant Research

Although the value of leguminous crops in the pattern of Western Australia's agriculture has been recognised for a number of years (Gladstones (1968))*, they have received comparatively little scientific attention. Whilst one such crop, the "sweet" lupin, has occasionally produced highly profitable yields, there is nevertheless a high incidence of near failures which may to a large degree be logically attributed to lack of knowledge of the basic agronomy of the crop. As a preliminary to more extensive trials at a large number of locations, it was proposed to study the effect of some basic agronomic practices (and of the …

Lupin And Serradella Inoculation Experiments, D L. Chatel

Experimental Summaries - Plant Research

BACKGROUND: During 1967 there were a number of reports of poor establishment of Weiko and Uniwhite lupins. Because of the possibility of either delayed nodulation or insufficient nitrogen fixation being involved, an experiment was conducted during 1968 to examine a range of lupin rhizobia isolates in the field (a summary of this experiment was circulated during 1969). In this experiment two strains, WU425 and WU43, showed sufficient promise to warrant additional testing in 1969.

Molybdenum Recommendation For Legumes, J. L. Sims, Warren C. Thompson, S. H. Phillips

Agronomy Notes

Molybdenum is recommended in Kentucky for legumes (soybeans, alfalfa, clovers and other forage legumes) beginning in 1969. The application should be made as a seed treatment and at the rate of 0.4 to 0.8 (4/10 to 8/10) ounces of molybdenum per acre. Molybdenum is recommended only on soils testing less than pH 6.2.

Nodulation Of Legumes On New Light Land. 1. Survival Of Rhizobia On Inoculated Pelleted Seed Held For Varying Periods Before Sowing Into Dry Soil, O M. Goss, W. A. Shipton

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

MOST of the light land areas being opened up in Western Australia are very sparsely populated with the rhizobial bacteria so essential for successful legume establishment.

Seed inoculation is therefore a necessity.

Farmers often have to resort to dry sowing because of the large acreages being planted or late opening rains.

Nodulation Of Legumes On New Light Land. 4. Rhizobial Strains For Pasture Establishment, O M. Goss, W. A. Shipton

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

LEGUMES are the basis of improved pastures in Western Australia.

Successful establishment of these legumes depends on the presence in the soil of suitable bacteria which will invade the roots and develop nodules in which nitrogen fixation is carried out. The nitrogen compounds produced are utilised by the plants, making them independent of soil nitrogen.

At the end of the season, the decomposition of the plant residues improves soil fertility.

Nodulation Of Legumes On New Light Land. 2. Protection Of Rhizobia From The Toxic Action Of Superphosphate And Trace Elements, O M. Goss, W. A. Shipton

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

VAST areas of new light land being developed in Western Australia are deficient in trace elements such as copper, zinc and molybdenum as well as in phosphorus.

These fertilisers are known to be damaging to the rhizobial bacteria inoculated on the seed unless they are protected by lime pelleting.

Nodulation Of Legumes On New Light Land. 3. The Effect Of Rogor Seed Treatment On Legume Nodulation, O M. Goss, W. A. Shipton

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

SEED treatment with systemic insecticides is widely used for the control of insect pests. However, when seed inoculation is necessary for pasture establishment, seed treatment with insecticide is not advisable.

A field experiment conducted at Badgingarra Research Station in 1964 showed that the systemic insecticide Rogor was very damaging to the applied rhizobia even when the treated seed was held for a month before inoculation.

Inoculation And Lime-Pelleting Of Leguminous Seeds, W P. Cass Smith, Olga M. Goss

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

IN Western Australia extensive areas of new land are brought under cultivation each year.

Much of this virgin soil is only sparsely populated with the beneficial rhizobial bacteria which nodulate the roots of common pasture and forage legumes, such as subterranean clover, barrel medic, lucerne and field pea.

Yields In Different Cropping Systems And Fertilizer Tests Under Stubble Mulching And Plowing In Eastern Nebraska, F. L. Duley

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The material in this report will be confined chiefly to studies on crop production with stubble-mulching compared with plowing. Major cash crops have been studied in different rotations including legumes and non-legume crops. In all tests, plowing has been compared with subsurface tillage. Different types of equipment have been devised and tested for the various operations during the course of these studies.

Nebraska Pastures: Seeding And Management, A. L. Frolik, E. F. Frolik

Nebraska Agricultural Experiment Station: Historical Circulars

Pastures are an important source of feed in the livestock industry. Approximately 70 per cent of the income from Nebraska farms is from the sale of livestock and livestock products, and for this reason consideration should be given to the maintenance of good pastures. Poor pastures, like other poor crops, are expensive. Good grass cover is also an effective means of conserving the soil resources.

Studies Of Prairie Hay In North Central Nebraska, F. D. Keim, A. L. Frolik, G. W. Beadle

Nebraska Agricultural Experiment Station: Historical Research Bulletins

During five years, 1924-1928, Nebraska ranked first among the states in the production of prairie hay. Approximately 2,500,000 tons were grown annually during this period. In acreage utilized, wild hay ranked third among the field crops of Nebraska. As a forage crop in the state, prairie hay ranked first in acreage, but second to alfalfa in production. The purpose of this bulletin is to report studies made of the botanical structure and yields of the native hay meadows during a period of four years, 1926-1929, in the most prominent prairie hay producing section of the state. Four counties in this …
