Summer Annual Grasses - Kentucky, W. H. Stroube

Agronomy Notes

During the summer of 1965 , several varieties of summer annual grasses were seeded at the rate of 10-12 pounds per acre, in rows 3 feet apart, at the Woodford County Farm and at the Western Kentucky Substation. These varieties were replicated four times and harvested three times at each location. Harvest data are reported in the attached table. It should be noted that data from Woodford county are reported in dry matter per acre and that from Princeton in air-dry forage. Previous studies have indicated that yield data from 3-foot rows of this type of material should be multiplied …

Zinc Deficiency In Corn, Harold Miller, Shirley Phillips

Agronomy Notes

Status of Zinc Deficiency

Corn is the only field crop presently grown in Kentucky that has shown zinc-deficiency symptoms and that has definitely given a response to zinc applications. Isolated instances of zinc deficiency have been reported from nearly every area of the state. However, the difficulty appears to be more prevalent in soils of the central Bluegrass and the western Pennyrile regions.

Considerable variation in respect to zinc deficiency has occurred within these regions, characterized by no consistent pattern. Corn producers in these areas particularly should watch this crop closely for deficiency symptoms during the period 4 to 6 …
