The bulletin reports on the first four years of the Maine Potato Ecosystem Project, a long-term, multidisciplinary study of alternative crop management strategies. The study site is a 15-acre tract on the northern boundary of the University of Maine's Aroostook Farm in Presque Isle, Maine, divided into 96 main plots that are grouped into four blocks. Each block is an area where soil survey data show similar soil characteristics. Thus, given the same production inputs, the crop output is expected to be the same on each plot within a block. Within each block there are 24 plots to which the …

In Aroostook County, Maine, where the annual average rainfall is 35-40 inches, it is generalized by many that moisture is not a limiting factor in potato production. Weather data for Aroostook do, however, show frequent periods of low rainfall during the growing season, and these periods do cause temporary moisture deficiencies in the crop. Struchtemeyer, based on irrigation research in Maine, showed that the potato plant needs approximately 1 inch of water per week during the growing season. From the 1936 to 1955 Maine Weather Records, Pullen and Schrumpf (23) found that about 70 percent of the time, less than …

Bulletins
This bulletin presents the results of research on three aspects of the disease blossom and twig blight, (1) seasonal development, (2) the effect of environmental factors, and (3) chemical control. The work was supported financially by Maine Blueberry Tax funds.
