The Use Of Foliar Applied Zinc Compounds In Correcting Zinc Deficiency In Fruit Crops, Lynn F. Hall
The Use Of Foliar Applied Zinc Compounds In Correcting Zinc Deficiency In Fruit Crops, Lynn F. Hall
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The effectiveness of two chelated zinc compounds in correcting zinc deficiencies was studied. Soil and foliar treatments were made to study possible residual zinc carry-over from one season to the next. Foliar treatments at various rates were applied to raise plant tissue zinc levels above deficiency levels. It was found that none of the treatments studied resulted in any substantial carry-over of zinc to the following year. All of the foliar zinc treatments resulted in an increase in leaf zinc content in all of the varieties of fruit studied. The level of zinc in the treated trees increased in proportion …

Influence Of Time Of Application Of Nitrogen Fertilizer On Corn Yields, Harold F. Miller, Kenneth Wells, Morris J. Bitzer, G. W. Thomas, R. E. Phillips
Agronomy Notes
Soil moisture conditions can have a large effect on crop responses to nitrogen fertilization. Kentucky's usual climatic pattern of periods of heavy rainfall and relatively warm temperatures during the winter and spring seasons influences expected yield responses of corn to applied nitrogen. If nitrogen fertilizer is applied in late winter or early spring, some of it may be lost before the plants have made sufficient growth to take up appreciable quantities. The amount of loss that might be expected will be influenced by the amount of rainfall, temperature, amount of organic matter and drainage of the soil.
