Book Description
"The importance of red claver (Trifolium pratense) as a forage crop; growing concern about both seed and hay yields; the failure of almost continuous research on varieties, seed setting etc. to greatly improve the situation in Quebec, and preliminary surveys indicating a very high percentage of two year old plants infested by the clover root borer (Hylastinus obscurus (Marshem)), gave rise to these investigations. It has been generously supported by a grant-in-aid for the purpose, from the Quebec Agricultural Research Council to Dr. Frank Morrison." --

Book Description
"By far the most important legume grown on Quebec farms is red clover, Trifolium pratense L. It has, however, been falling short of its potential productivity in this area. Within recent years, considerable research has been conducted with a view to evaluating the effects of various factors on the longevity and vigour of the red clover plant. The current view is that a complex of interacting factors, including varietal differences, weather conditions, and the attack of a large number of insect species, fungus diseases and possibly nematodes is involved in reducing the yield of this crop." --
