Kans. Control of Insects Injurious to Alfalfa and Allied 



Plants' ! To (1) study all of the insects which obtain 

 their living primarily or secondarily from alfalfa or 

 allied plants; (2) test old and new control measures for all 

 those species which cause commercial damage; (3) study 

 annual fluctuations of more important species in an effort 

 to understand the causes of abnormally large or small 

 population; and (k) determine effects of high temperatures 

 in the field and the effects of cutting on populations of 

 alfalfa insects.

Kan s . Dev eloping and Testing Pasture-Type Alfalfas . 



(l) Evaluate various alfalfas, including foreign intro- 

 ductions, as to their ability to persist and survive under 

 the extreme climatic and management practices that prevail 

 on the range. (2) Develop, from the best strains, through 

 selection and breeding, adapted high yielding, disease- and 

 insect-resistant varieties. (3) Study the behavior of pasture- 

 type alfalfas under different management practices and soil 

 and climatic conditions, (k) Conduct uniform variety yield 

 trials involving pasture types.

Ky. Seed Production in Red Clover and Alfalfa . To deter- 



mine (1) effects of different cultural and fertilizing 

 practices and of insect control measures upon seed yield 

 and quality, (2) amounts and causes of seed losses in 

 harvesting, (3) isolation necessary to prevent significant 

 crossing of varieties, and (k) degree of loss in crop adaptation 

 occurring in successive seed generations produced under farm 

 conditions.
