Boron Fertilization Of Corn In Kentucky, Lloyd W. Murdock, Kenneth L. Wells, H. F. Miiller
Boron Fertilization Of Corn In Kentucky, Lloyd W. Murdock, Kenneth L. Wells, H. F. Miiller
Agronomy Notes
The need for use of boron (B) for alfalfa production has been recognized for many years in Kentucky and is presently recommended for general use as an annual topdressing on alfalfa fields. Use of B is also recommended in Kentucky for red clover fields which are to be harvested for seed. In recent years, there has been interest in use of fertilizer B for good corn production in Kentucky. Plant available B is greatly affected by soil pH and decreases with increasing soil pH. Because of this, some states recommend use of B on corn grown on soils with a …

G77-382 Right Crop Stage For Herbicide Use Corn, Sorghum, Small Grains (Revised May 1992), Drew J. Lyon, Robert G. Wilson Jr., Alex Martin
University of Nebraska-Lincoln Extension: Historical Materials
Herbicides recommended for postemergence application in corn, sorghum, and small grains are discussed in this NebGuide. Proper timing of postemergence herbicides is essential to achieve maximum weed control and minimum crop injury. As field crops grow and mature, their tolerance to herbicides changes. As a general rule, annual and biennial weeds are more susceptible to postemergence herbicides when they are in the seedling stage. As they mature they become increasingly difficult to control, facing the grower with the problem of when to apply the herbicide to achieve the least crop injury and the most satisfactory weed control. Field crops differ …

G77-340 Scheduling Irrigation By Electrical Resistance Blocks, Paul E. Fischbach
University of Nebraska-Lincoln Extension: Historical Materials
Delay of irrigation for a few days during a critical part of the growing season can be expensive. A week's delay in supplying irrigation water to corn or grain sorghum can reduce potential yield more than 30 bushels per acre.
Several methods are available to help you schedule the right amount of water at the right time. One of these methods uses electrical resistance blocks discussed in this NebGuide.
