Preserve And Use Tobacco Stalks, George D. Corder

Agronomy Notes

When Kentucky's 1964 tobacco crop is stripped , there will be about 176,000 tons of stalks in and around stripping barns. There will be more than $2 million worth of nitrogen, phosphorus and potassium in them.

If these stalks are left outside the barn and exposed to winter rains, 61 percent of the nitrogen, 38 percent of the phosphorus, 83 percent of the potassium and 41 percent of the organic matter may be lost.

Use Of Phosphate Fertilizers And Bedding To Preserve Manures, George D. Corder

Agronomy Notes

Superphosphate fertilizers added to farm manures as they accumulate in barns, feed lots, and loafing areas will reduce the loss of nitrogen as gaseous ammonia.

Farm Manures, George D. Corder

Agronomy Notes

More than 16 million tons of farm manures valued at more than $47 million are produced on Kentucky farms each year.

Almost half of these manures accumulate in barns, feedlots, and loafing areas. A large part of this will accumulate in these areas between now and pasture time next spring. These manures must be removed from time to time and the cost of handling is unavoidable. Preserving their value and using them wisely on crops and soils that benefit from them will give a fair return on handling costs.

Agronomy Notes, No. 19, George D. Corder

Agronomy Notes

A Test Ban Treaty designed to stop nuclear explosions above ground was signed. World tension was eased. Fear of radioactive fallout was lessened. The Chinese have the atomic bomb. They did not sign the Test Ban Treaty. World tension is on the up-swing.

What has all this to do with agriculture in Kentucky?

Borax, Borates, And Other Boron-Carrying Compounds, Harold F. Miller

Agronomy Notes

Boron is available on the market in a number of different compounds. Since the amount of boron contained in each compound is different, the concentration will determine the rate required per acre. Frequently, all of these boron-containing compounds are erroneously referred to as borax (11.36 percent boron).

Organic Toxicity, Jones H. Smiley, Ira E. Massie

Agronomy Notes

In recent years there has been much discussion on the subject of organic matter toxicity and its relation to the severity of black root rot of tobacco. Organic matter toxicity is due to or at least related to toxins produced during organic matter decomposition.

Fertilizer-Insecticide Mixtures On Corn, R. L. Miller, George D. Corder

Agronomy Notes

Soil fertility and insects are major factors that affect corn yields. The proper kinds and amounts of fertilizers and insecticides properly placed will make corn production more economical on fields where either or both are needed.

Fertilizer-Insecticide Mixtures On Tobacco Plant Beds And Fields, George D. Corder, R. L. Miller

Agronomy Notes

Fertility and insect control programs have a major influence on tobacco production. The proper amounts and kinds of fertilizers and insecticides properly placed will make production more economical on beds and fields if either or both are needed.

Is a fertilizer-insecticide mix the best way to meet the fertility needs and t he insecticide needs on tobacco? The following questions and answers should help show how the decision was reached that this method is not recommended.

Sulfur Fertilizers For Alfalfa Production In Nebraska, R. L. Fox, A. D. Flowerday, F. W. Hosterman, H. F. Rhoades, R. A. Olson

The sulfur supplying capacities of various soils under field and greenhouse conditions. 4. The sulfur content of precipitation at widely scattered points in Nebraska. 5. Soil properties associated with sulfur deficiency. 6. Optimum methods for estimating the sulfur status of soils by soil testing. The …

Stem Rust Of Wheat, H L. Harvey

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

STEM RUST is one of the most serious diseases of wheat and is of world-wide importance.

Fortunately, widespread epidemics are rare in Western Australia because the general climatic conditions are usually unfavourable to the disease.

Nevertheless, localised outbreaks of stem rust are quite common on the Esperance Plains and around Geraldton where seasonal conditions are frequently mild and humid.

Recommended Wheat Varieties, 1965 : State Wheat Advisory Committee Recommendations For Wheat Varieties For 1965 Plantings, Department Of Agriculture, Western Australia

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

State Wheat Advisory Committee recommendations for wheat varieties for 1965 plantings.

THE wheat rust epidemic of 1963 has directed attention to resistance of varieties to this disease, new races of which have recently appeared in Western Australia.

However, last year was one of abnormal seasonal conditions, with late summer rains followed by a mild winter, and spring conditions which favoured rust.

Insect Pests Of Cotton In The Ord River Irrigation Area, K T. Richards

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

COTTON is grown in the Ord Valley of north Western Australia, mainly as an annual, irrigated crop during the hot summer months of the "wet season".

It is usually planted in November-December and harvested March-May.

This period of growth corresponds closely to that of maximum insect activity.

A Chemical For Doublegee, Geoffrey A. Pearce

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

DURING the past two years, finance has been made available from the State Wheat Research Fund for an intensive study on doublegee.

A newly-developed herbicide has been shown to give complete control of growing plants, while ecological studies have started to yield valuable information about seed behaviour.

Root Rot Of Legumes Caused By Cylindrocladium Scoparium, Daryl A. Freter, Roy D. Wilcoxson

Journal of the Minnesota Academy of Science

Massey ( 3) in 1927 was the first to report that Cylindrocladium scoparium Morgan could parasitize plants. In 1928 Sherbakoff ( 4) isolated the fungus from a chlorotic red clover plant and from diseased apple roots. Cox (2) proved that C. scoparium can cause damping-off, root rot, stem infection, and needle blight on seedlings of several conifers. He also found that C. scoparium was highly pathogenic on several species of Leguminosae. Bugbee ( 1 ) reported alfalfa to be ideal for detecting C. scoparium in soil in the greenhouse because the seedlings damped-off and the fungus sporulated on the seedlings. …

Lucerne Establishment On The West Midland Sandplain, J W. Gartrell

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

WEST of Dandaragan and the Midland line from Watheroo to Mingenew there are four million acres of scrubplain commonly called the Western Sandplain.

All virgin soils in this region are acutely nitrogen deficient so that the agricultural future of the region depends on how successfully legumes are grown.

Silage Making In The Lower South-West, A L. Hamilton

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

The history of silage making in the South-West of Western Australia is typified by periods of relatively intense activity followed by periods when the activity virtually ceases.

The recent rise in popularity has followed the introduction of machinery or methods which tend to make the job easier to handle, or which improve the quality of the silage.

Linseed Growing In The Ord River Valley, D F. Beech

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

Experimental work with linseed at the Kimberley Research Station began in 1952 and has been intensified in the last four years.

Fertiliser requirements and methods of land preparation, sowing, irrigation and weed control have been established.

Suitable varieties have been selected. Farm-scale crops have been grown in the area and, although cotton is very much more remunerative as an establishment crop, it is expected that linseed will ultimately have a place in the Ord irrigation scheme.

Take-All Of Wheat On The Esperance Downs : The Effect Of Multiple Cropping, S C. Chambers

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

A considerable increase in take-all occurred in the second crop of wheat following linseed, oats or vetches at the Esperance Downs Research Station.

THE take-all disease of wheat, caused by the fungus Ophiobolus graminis, has been responsible for many crop failures in the Esperance district during the past 15 years.

In an endeavour to find a practical solution to this problem, a crop rotation experiment was started in 1961 at the Esperance Downs Research Station.

Take-All Of Wheat On The Esperance Downs : The Ffect Of Nitrogenous Fertiliser, S C. Chambers

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

The number of wheat tillers affected by take-all was not influenced by the application of ammonium sulphate in an experiment at Esperance Downs Research Station.

However, its use stimulated tillering and increased yields by an estimated 7.4 bushels an acre.

Phosphate Requirements Of Rice In The Ord River Valley, Rijn P J Van, A. L. Chapman

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

A three-year experiment on the initial and maintenance phosphate requirements of wet-season rice was carried out at Kimberley Research Station between 1960 and 1963.

Application of 2 cwt. per acre superphosphate as the first application on new land, followed by annual application of 1J cwt. per acre is recommended.

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.

The 1963-64 Wheat Stem Rust Epidemic, J T. Reeves

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

Comments on the 1963 epidemic and the current situation regarding rust races and resistant varieties in Western Australia.

THE 1963-64 harvest included 12 million bushels of undergrade wheat, representing 25 per cent, of the total harvest.

The average yield was reduced to only 11.3 bushels per acre. Although these adverse effects were due to a number of causes, the principal one was stem rust.

The economic loss due to this disease in the 1963-64 harvest probably exceeded £10 million.

Take-All Disease Of Wheat, S C. Chambers

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

Take-all is the most serious of the several root-rotting diseases of wheat in Western Australia.

In the absence of cereal crops, the fungus responsible for take-all survives on the roots of native grasses.

Losses can be minimised by adopting cultural methods which reduce the amount of infective material in the soil and which also encourage vigorous growth of the crop.

Oat Variety Trials, 1962 And 1963, J L. Mcmullan

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

OAT variety trials were located on a number of Research Stations and, in 1963, on three other properties in the higher rainfall areas.

These three trials contained only varieties of midseason maturity.

The location of the test centres is given in the tables, while brief details of the varieties and crossbreds under test in the period 1962-64, inclusive, are given in Table 1.

Linseed Variety Trials, 1963-64 Season, J T. Reeves

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

RESULTS of 1963-64 linseed variety trials are available for four trials on research stations and for four trials on farmers' properties.

These are shown in the table below. Excellent yields were obtained at some sites, while disappointing results were obtained at Chapman and Esperance.

Poor results at Esperance were due to the poor finish to the season.
