Pedology Of Corn Productivity Indices For Selected Parts Of Southern Highland Zone Of Tanzania, Johnson Godlove Mtama Jan 2015

Pedology Of Corn Productivity Indices For Selected Parts Of Southern Highland Zone Of Tanzania, Johnson Godlove Mtama

Graduate Theses and Dissertations

Scientific investigations to determine land use planning and interpretations for corn productivity potential in the Southern Highland Zone of Tanzania were conducted. The assessment of soils corn growth potential has been conducted in four selected pedons namely; Uyole, Mbimba, Inyala and Seatondale. Pedological, physical, chemical characterization and an attempt to develop the pedotransfer functions were done. The results show that the soils have deep to very deep sola, subangular blocky structures, evidence of pedogenic clay movement, fine to coarse texture, bulk density ranged from 0.79 to 1.46 g/cm3, pH ranged from slightly acidic to slightly alkaline, cation ...


Associations Between The Family Nutrition And Physical Activity Screening Tool And The Youth Activity Profile, Kimberly Ann Klimesh Jan 2015

Associations Between The Family Nutrition And Physical Activity Screening Tool And The Youth Activity Profile, Kimberly Ann Klimesh

Graduate Theses and Dissertations

Childhood obesity affects one third of children and adolescents and is expected to increase in coming years. Obesity has been linked to both genetic and environmental factors with more recent research focusing on the role parents play in childhood obesity. The Family Nutrition and Physical Activity (FNPA) Screening tool was developed to provide practical ways to evaluate home obesogenic environments. However, no study to date has examined associations between FNPA scores and child behaviors. Therefore, the purpose of this study was to examine associations between FNPA scores from parents and child reported lifestyle behaviors as assessed by an established self-report ...


Motivation And Retention Of Iowa’S Master Gardener Volunteers, Bryn Takle Jan 2015

Motivation And Retention Of Iowa’S Master Gardener Volunteers, Bryn Takle

Graduate Theses and Dissertations

Retention of participants in volunteer organizations has been shown to be not only a challenge, but also a great benefit to the organization. Rising costs of training and continuing education make each interaction valuable from both perspectives. Volunteer opportunities are abundant but must be meaningful and engaging for the participants in order to keep them involved. Using electronic survey software, Iowa Master Gardeners were asked to respond to a series of questions investigating 1) the current demographics of the population, 2) reasons volunteers associate with the Master Gardener program, and 3) the continuing education topics and delivery methods most preferred ...


Emerging Issues In The U.S. Corn Belt: Infection Of Corn By Clavibacter Michiganensis Subsp. Nebraskensis And Use Of Foliar Fungicides To Protect Yield, Salome Mallowa Obura Jan 2015

Emerging Issues In The U.S. Corn Belt: Infection Of Corn By Clavibacter Michiganensis Subsp. Nebraskensis And Use Of Foliar Fungicides To Protect Yield, Salome Mallowa Obura

Graduate Theses and Dissertations

Currently two major issues pertaining to disease management in corn production in the US Corn Belt are the spread of Goss's wilt and leaf blight caused by Clavibacter michiganensis subsp. nebraskensis (Cmn), and the use of foliar fungicides on corn for `plant health' benefits. This dissertation presents data regarding infection of corn by Cmn, and fungicide effects on disease management and yield.

Greenhouse and laboratory research was undertaken to determine if infection of corn by Cmn may occur without severe wounding, such as that caused by hail, sand blasting or wind damage. Corn plants with no obvious wounding were ...
