Evaluation Of Body Size Parameters In Elite Angus Cattle, Wilson Stone
Masters Theses & Specialist Projects
The cattle shown at the prestigious All-American Angus Futurity were studied in order to evaluate the relationship between various body measurements. The measurements taken included wither height, hip height, body length, fat thickness,and weight. Also, these measurements were analyzed in order to determine if Angus cattle had gained in genetic frame size. Data were collected for the 805 animals shown in the years 1974 through 1978.
The cattle were grouped into classes based upon sex and age prior to any statistical procedures being performed. Means of classes were used in order to evaluate sex differences and bulls were found to …
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 …
