N. C. A Study of the Nutritional Status^ Requirements, and 

 Methods of Correcting Deficiencies of Blueberry and Straw - 

 berry Plantings in North Carolina , To (1) learn optimum 

 nutrient-element contents of leaves of blueberry smd straw- 

 berry plants in State; (2) compare these standards with 

 leaf nutrient -element contents of State strawberry and blue- 

 berry plantings; (3) obtain basic nutritional stat\is data 

 to guide development of additional nutritional research; 

 and, (U) formulate and perform corrective field experiments 

 which will be indicated as desirable by leads uncovered 

 through basic data developed by elementary greenhouse and 

 survey data.

Ohio Responses of the Red Raspberry to Different Soil Manage - 



ment Practices, Training Systems, and Rates of Nitrogen 

 Fertilization as Indicated by Growth, Yield and Mineral 

 Nutrient Content of the Leaf . To determine (1) effect of 

 different soil management practices, differential N fertili- 

 zation, and training systems upon growth ajad yield response 

 of red raspberry; (2) pattern of development of red rasp- 

 berry fruit, and of individual druplet; and, (3) effect of 

 differential N applications on development of fruit and 

 individual druplet,

Ohio A Study of the Nutrient Status of Ohio Vineyards and 



of the Effect of Various Pruning, Soil Management and Fe"rti - 

 lizatlon Practices on the Growth, Yield and Quality of Grapes . 

 To (1) survey representative Ohio vineyards to find essential 

 nutrient element status of commercially important varieties 

 as indicated by foliar analysis; (2) investigate severity of 

 pruning in order to obtain information upon which specific 

 recommendations for grower pruning practice may be based; 

 and, (3) determine influence of various soil management and 

 fertilizer practices on yield and quality of Concord and 

 Delaware grapes,

Oreg. The Floral, Vegetative, and Physiologic Response of 



Certain Plants to Specific Temperatures and Photoperiods . To 

 (1) obtain basic information regarding the floral, vegetat i ve 

 and physiologic response of the strawberry and other plants 

 sensitive to specific temperatxires and photoperiods; and, (2) 

 ultimately obtain sufficient basic information to establish 

 specific relation between mineral uptake, carbohydrate accu- 

 mulation, protein synthesis, etc. and partic\ilar teniperattires 

 and photoperiods,
