B753: The Uptake Of Nutrients By Katahdin Potatoes As Influenced By Soil Moisture Regimes And Rates Of Fertilization, Gurbachan Singh Kalra, Roland A. Struchtemeyer

Bulletins

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 …

Honey Plants In Western Australia, F. G. Smith

Bulletins - 3000 - 3999

Successful honey production depends, among other things on a good knowledge of the plants which produce nectar.

Every apiarist needs to know which plants are of importance to honey-bees, where those plants occur, and when they flower. He also needs to know which plants produce nectar which will result in the production of good quality honey, and which produce unpalatable or unmarketable honey. To maintain the strength of his bee colonies he also needs to know which plants produce nutritious pollen.

The object of this bulletin is to provide the basic information on these subjects in the main beekeeping areas …

Bulletin 200 - Trees And Shrubs Of The Campus And East Central Illinois, Ernest Stover

Eastern Illinois University Bulletin

The keys to the trees, shrubs and vines have been revised

in an attempt to make them more usable for the beginning student.

The keys to several of the genera, pines, oaks, ashes, willows,

etc., have been rewritten and species added that were not

in the previous printings.

The key to the trees in winter has been added hoping that it

will be helpful to both teachers and students. The identification

of trees without their leaves during the winter is not only interesting

but useful.

The identification of plants is but one phase of their study.

Botany is the basic …

The Pinetum Britannicum, Edward Ravenscroft

Archives & Reprint Series (imprint)

The Pinetum Britannicum: A Descriptive Account of Hardy Coniferous Trees Cultivated in Great Britain was authored by Edward James Ravenscroft (1816-1890) during the time period of 1863 through 1884.

This first edition Pinetum Brittanicum is regarded as an important British study of pines.

Ravenscroft was a master in the field of natural history illustration, which is often called “art in the service of science.”
