Ind. Alfalfa I mprovement Th roug h Se lection and Breedin g. 



To develop by breeding and selection high yielding, disease 

 and insect resistant varieties of alfalfa of high 

 nutritional quality well adapted to environmental 

 conditions of Indiana,, 



For., PI. Path., Ent. Agron. 2^5 



Ind . The Effects of Insect s, Insecticides, and Cultural 



Prac t ices on the Qual i ty and Quantity of For a ge and See d 

 Yields of Alfal fa. To study (1) effects of new insecticides 

 on insect populations and on alfalfa plant yields and 

 quality; (2) seed production as influenced by various 

 cultural methods as seeding, overhead irrigation, and 

 blooming dates as influenced by time of cutting; and 

 (3) pollinators as affected by chemicals to control 

 injurious insects and determine time that most beneficial 

 pollinators are at a maximum so that alfalfa crop can be 

 planned to coincide with the period.

Kans . The Effects of Diff erent S ystems of Management of 



Grassl ands and Conservation Areas Upon the Insects Injur ious 

 to Gras ses . To determine cause and extent of insect injuries, 

 study relationship between grassland insects and insect 

 injuries to adjoining crops, study life histories, habits 

 and control of grassland pests, and observe grass species 

 and selections for differential insect injury.

Kans . In sects Affecting Alfalfa Hay and Seed Production . To 



(l) determine (a) the value of newer insecticides for control 

 of plant bugs and other injurious insects, (b) effect of 

 these insecticides on alfalfa seed and hay production, 

 (c) effect upon alfalfa pollinating insects, and (d) species 

 concerned with pollination of alfalfa by insects and rate of 

 tripping of each; and (2) devise (a") methods of increasing 

 numbers of honeybees and solitary bees per square yard in 

 alfalfa fields, and (b) controls for insects which live on 

 alfalfa seed while seed is in storage.
