Effect Of Fertilization And Management On The Production Of Bromegrass In Northeast Nebraska, G. W. Rehm, W. J. Moline, E. J. Schwartz, R. S. Moomaw

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Several experiments were conducted in northeast Nebraska to determine the effect of fertility and management practices on the production of smooth bromegrass (Bromus inermis Leyss). The effectiveness of the various fertilizer treatments was measured in units of dry matter produced per acre as well as beef produced per acre. Results of these studies showed that the production of bromegrass pastures in Nebraska could be markedly improved through proper fertilization.

Tips For Small Grain Seeding, Morris J. Bitzer, James H. Herbek, Dennis M. Tekrony

Agronomy Notes

TEST YOUR SOIL AND SUPPLY THE SUGGESTED LIMING AND FERTILIZER MATERIALS.

A soil test is the first step to profitable small grain production. A pH of 6.0 to 6.5 is best, and nitrogen should be applied both in the fall and spring. If your small grains are part of a double cropping system the P and K requirements for both crops should be applied in the fall.

Uptake And Distribution Of Mineral Elements By Burley 21 Tobacco As Influenced By Nitrogen Nutrition And Suckering Practice, J. L. Sims, W. O. Atkinson Aug 1971

Uptake And Distribution Of Mineral Elements By Burley 21 Tobacco As Influenced By Nitrogen Nutrition And Suckering Practice, J. L. Sims, W. O. Atkinson

Agronomy Notes

Knowledge of nutrient content of tobacco and of removal of nutrients from soil is essential to developing sound fertilization practices for tobacco. Quantities of nutrient elements taken·up by tobacco vary widely. This is because of variations in variety, soil fertility level, fertilizer application, soil moisture, plant population, and other environmental and cultural factors . We conducted the present study to determine the effects of applied N and suckering practice on the content of mineral elements in certain plant parts of burley tobacco.


Soil Surveys In Kentucky, Harry Hudson Bailey, Robert L. Blevins Jul 1971

Soil Surveys In Kentucky, Harry Hudson Bailey, Robert L. Blevins

Agronomy Notes

Soil surveys are a scientific inventory of the soil and land resources of an area. They locate the different kinds of soils and provide information as to their physical and chemical properties. The survey reports also contain tables and charts showing the use of the soils for agriculture, engineering, community development, recreational areas, woodland, and wildlife.

Today there is some type of soil survey activity in every county of Kentucky. The University of Kentucky has cooperative soil survey arrangements with the USDA Soil Conservation Service and the U.S. Forest Service.

Forage Sorghum And Forage Pearl Millet Performance Lexington, Kentucky 1970, Roy E. Sigafus Jun 1971

Forage Sorghum And Forage Pearl Millet Performance Lexington, Kentucky 1970, Roy E. Sigafus

Agronomy Notes

Most livestock producers, especially dairy farmers, have a need for a high quality roughage in summer when cool-season grass pastures are normally low in production. Alfalfa and clover-grass mixtures grazed rotationally, and small grain and "grass" silage or hay are common sources of summer feed . There is an increasing interest, however, in forage sorghums and forage millets for grazing or green-chop .

Effect Of Nitrogen Fertilization On Yield Of Burley Tobacco, J. L. Sims, W. O. Atkinson, Jones H. Smiley, Allen M. Wallace May 1971

Effect Of Nitrogen Fertilization On Yield Of Burley Tobacco, J. L. Sims, W. O. Atkinson, Jones H. Smiley, Allen M. Wallace

Agronomy Notes

Relatively large amounts of nitrogen from fertilizers and manures commonly are used in burley tobacco production. Growers are currently estimated to apply between 150 and 400 pounds of actual N per acre. Fertilization of burley with nitrogen significantly affects the physical and chemical characteristics of cured leaf and produces changes in yield and value. On most soils, leaf yields usually are increased by applications of N fertilizer, but the amount of yield increase per unit of applied fertilizer N varies widely between soils. High rates of N applied preplant or at planting often retard early plant growth, delay maturity, and …

The Economics Of Spray Seed, J W. Malcolm

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

THE "Spray Seed"* technique has many advantages over conventional cultivation methods of weed control. Some of these are matters of convenience, preference or opinion, and these cannot be measured in general economic terms.

However, most farmers are in the business to make money and as making money becomes harder they are more concerned with the extra money a new move is likely to earn for them.

Grain Sorghum In The Ord Valley : Three Crops A Year?, P J. May Jan 1971

Grain Sorghum In The Ord Valley : Three Crops A Year?, P J. May

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

High temperatures and ample irrigation water allow grain sorghum to be grown throughout the year on the Ord River Irrigation Area, and observations in 1969-70 indicated that it may be possible in this area to produce three crops in one year from one planting, by ratoon cropping.

This article describes the technique and discusses its possibilities on the Ord.

The sorghum midge, one of the worst pests of sorghum, could well make ratoon cropping impossible, but the midge has not yet been seen in this area.
