Why Does Second-Cutting Red Clover Hay "Slobber" Animals, J. Kenneth Evans, A. S. Williams, D. E. Labore

Agronomy Notes

For years, farmers have noticed the slobbering of animals after feeding second-cutting red clover hay. Severity of this effect, however, has varied from year to year. Questions asked many times are what causes the slobbering and what can be done about it? To get the answers available, let's go back about 37 years into something which appears to be totally unrelated to slobbering and follow research which has been done on a fungus, which causes a disease of red clover.

Yield And Value Of Burley 21 Tobacco As Influenced By Nitrogen Nutrition, Suckering Practice, And Harvest Date, J. L. Sims, W. O. Atkinson

Agronomy Notes

An experiment was conducted in the field during 1966 on Maury silt loam soil to obtain information of the effects of agronomic factors on yield and value of Burley 21 tobacco . Ammonium nitrate fertilizer at varying rates, and concentrated super-phosphate and potassium sulfate at constant rates , were broadcast and disked in after plowing and before transplanting. All plots received irrigation water (sprinkler system) to supplement rainfall when soil moisture dropped below 60% of available moisture-holding capacity. Sucker control practices utilized were (a) no topping - no suckering, (b) topping - no suckering, (c) topping - hand suckering, and …

Effects Of Ensiling On The Hcn Potential Of Sorghum Plants, Glenn Mccarty

Masters Theses & Specialist Projects

The effects of ensiling on HCN potential (HCN-p) of sorghum plants were studied at Bowling Green, Kentucky in 1969-70. Four cultivars were sampled at various growth stages and ensiled in 1.8 liter glass containers fitted with gas release valves. The plant material was analyzed for HCN-p by the sodium picrate procedure prior to ensiling, immediately after being removed from the silo, and after 24 and 48 hours of air-drying. Gases released during ensiling, and gases flushed from the silos were analyzed for HCN. The level of HCN-p decreased during the ensiling period and during the first 24-hour drying period. Some …

Reactions Of Pollen-Pistil Combinations In Vitro & Their Relationships To Compatibility In Alfalfa, Emerson Shipe

Masters Theses & Specialist Projects

Reactions of in vitro pollen-pistil combinations were studied and related to compatibility differences in Buffalo alfalfa Medicago sativa L.) at Western Kentucky University, Bowling Green. Pollen-pistil combinations were made at random among a number of alfalfa plants in 1968 (Experiment I). Pollen tube elongation varied significantly when -4 pollen from the same plant was placed on agar media containing pistils from different plants. Three of four plants for which intra-plant combinations (pollen and pistils from same plants) were made 1,ad tube lengths significantly shorter than those measured for inter-plant combinations (pollen and pistils from different plants).

Similar in vitro pollen-pistil …

Linseed Within The Clover Ley Farming System, Department Of Agriculture, Western Australia

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

LINSEED was one of the first crops to be widely used as an alternative to cereals in the over-17 inch rainfall areas. It is now an established crop with a total 1969 production worth just under half a million dollars.

Linseed is currently worth nearly twice as much as wheat per bushel, wih its short term prospects still attractive.

Weed Control Research Pays Dividends, G R W Meadly

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

On my bookshelf is a handbook entitled "War on Weeds" or "How to Double our Food Supply."

In many of these countries experiments have been made to ascertain as far as possible the exact damage done by weeds to crops.

Result: In all the experiments, whether made in England or abroad, the mean loss was over 50 per cent.

The level of loss is equally true today, but the methods at our disposal for handling weeds have improved tremendously.

Grain Aeration On The Farm, G D. Rimes

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

ALTHOUGH grain aeration is a well known and widespread technique employed to prevent insect development in stored grain, the installations are invariably designed for large scale grain handling authorities.

Experimental work carried out in Western Australia over the last four storage seasons has shown that simple unsophisticated equipment can be of direct use in farm storage.

Rationing Standing Crops To Sheep, H E. Fels

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

This experiment was done at Merredin Research Station to develop and test a method of rationing standing crops to sheep, and also to find whether rationing would reduce the sheep's water consumption.

The experiment involved 60 sheep on 12 one-acre plots of drought affected Gamenya wheat.

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

In a preceding article* we stated that the expansion of linseed in Western Australia was due primarily to the ability to sell on the export market at current ruling prices.

This is necessary because Australia's domestic needs are likely to be supplied in most years by Eastern States producers.

Urea Drilled With Seed Affects Germination And Yield, M G. Mason, A. Loutit, J. A. C. Smith, D. Highman, P. Stallwood

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

Trials in 1968 at Burracoppin and York again showed it is safer to topdress urea just before seeding than to drill a mixture of seed and urea.

At all but the lowest urea rates, urea drilled with the seed reduced the number of plants emerging and surviving, and reduced final wheat yields.

Lucerne Establishment In High Rainfall Dairying Districts, R Sprivulis

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

LUCERNE is one of the oldest of perennial forage plants. It originated in the Middle East and because it flourishes under a wide range of climatic and soil conditions it is being grown in many parts of the world.

Lucerne was introduced to Australia in the early years of British settlement. The original introductions proved suitable for the alluvial flats of the Hunter and Peel River valleys of N.S.W.

Lucerne is basically a summer growing legume with or without winter dormancy.

Rapeseed Production In Western Australia, M L. Poole

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

RAPESEED production began in Western Australia in 1968 when a few acres were grown. In 1969, about 20 growers ptanted small acreages for about 80 tons of seed. In 1970, up to 20,000 acres will be grown, and a total of 40,000 acres seems possible within the next few years.

Copper Requirements For The South-Eastern Wheatbelt, D J. Gilbey, K. D. Greathead, J. W. Gartrell

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

FARM experience and the results of five years intensive research have shown copper deficiency to be widespread in the south-eastern wheatbelt.

On many areas of the south-eastern wheatbelt, copper deficiency is likely to restrict wheat yields.

Growing Barley For Grain In Western Australia : Varieties And Production Methods, H M. Fisher

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

BARLEY is an adaptable crop which can be grown successfully throughout the cereal areas of Western Australia. It is more suited to the wetter areas than wheat and tolerates the drier, shorter season of the eastern cereal districts better than oats.

The Outlook For Barley, P J. Hackett, E. J. O'Loughlin

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

World production of barley in 1968 was 4,107 million bushels—an increase of 7 per cent, on the previous year.

Further increases are estimated for the 1969 season, especially in Canada and France. World production is expected to be 3 per cent, higher than in 1968.

The Making Of A New Pasture Variety, Department Of Agriculture, Western Australia

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

FARMERS who attend field days at Department of Agriculture research stations are reasonably familiar with the procedure for producing a new cereal variety. It involves a painstaking and tedious process of crossing, followed by many years of segregation, selection and testing for yield, disease resistance, and other characters.

Although there are many pitfalls, the procedure for the creation of a new cereal variety is at least fairly well systematised.

Until recently the making of a new pasture variety was far from a systematic undertaking.

Progress In Research On Noxious Weeds, Geoffrey A. Pearce

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

RESEARCH on noxious weeds has enabled the development of many practical methods for the control of these weeds.

Where the recommended treatments have been accepted by farmers, large scale operations have reduced the areas infested and stopped spread into new paddocks.

No-Tillage -- Suitability To Kentucky Soils, Robert L. Blevins

Agronomy Notes

As more farmers adopt no-tillage methods of farming the questions arises whether or not all soils are suited to this practice. To get an idea of how well suited the no-tillage method of corn production is to wide variety of soils, we made a survey in five different physiographic regions of Kentucky in 1969.
