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

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