1. D. Teare, Editor

This bibliography contains a listing of the research and extension articles published
during the year from July 80 to July 81 at AREC Quincy Marianna. Publications are
inventoried under the following classifications: Agricultural Economics, Agronomy,
Animal Science, Entomology, Soils, Plant Nutrition and Water Relations, Plant Breed-
ing, Plant Pathology, and Vegetable Crops. In each of these classifications, publica-
tions are delineated as articles in professional journals, bulletins, circulars and fact
sheets, research reports, other publications and abstracts.

This is the second in a series of periodic bibliographic listings of the publications
made by the faculty of the Agricultural Research and Education Center in Quincy -
Marianna, a branch of the University of Florida, Institute of Food and Agricultural
Sciences.

To avoid duplication of articles with multiple authors, the senior author determined
