111. Morphological Studies of Certain Agronomic Crops . To study 

 (1) morphological development of corn, wheat, oats, soybeans, 

 etc., and describe initiation and development of primordia of 

 parts of plant ; (2) cycle of development of above in different 

 seasons and under different growing conditions, learn when dif- 

 ferent seasons and under different growing conditions, learn 

 when different stages of development of plant occur and duration 

 of each stage; (3) morphological characteristics of above in re- 

 lation to corn and stem rust, strength of stalk or stem, and 

 other agronomic characteristics ; and (k) developmental morphology 

 of certain aberrant types of corn, wheat, oats, soybeans, etc.

Soil-Plant Relations 



Ark. Root Development of Forage Crop Species as Influenced by 



Physical and Chemical Factors of the Soil . Make lab., greenhouse 

 and field investigations of: (1) factors influencing root 

 growth; (3) field study and control of root growth (seasonal 

 variations in number and extent of roots, correlation of en- 

 vironmental factors with number of roots and extent of root system).

Calif. Brush Seedling Establishment and Growth in Relation to Soil 

 Fertility Levels . To determine (1) if brush increase is related 

 to soil fertility level; and (2) to what extent brush can be 

 controlled by increasing soil fertility through fertilization.

Fla. The Maintenance of Soil Fertility under Permanent Pasture . 

 To (1) study effects of different soil types and various manage- 

 ment practices on yields, composition of forage and animal re- 

 sponse; and (2) effect of these practices on physical and chem- 

 ical characteristics of soil and on maintenance of soil fertility.
