Climate Change And Idaho Agriculture: Is Farm Size A Determinate Of Adaptive Capacity?, Blair P. Vanderlugt
Climate Change And Idaho Agriculture: Is Farm Size A Determinate Of Adaptive Capacity?, Blair P. Vanderlugt
McNair Scholars Research Journal
Determining how agriculture will be affected by climate change is not only a question biophysical change in crop production; it also depends on the adaptation of the farmer to these changing conditions. A flaw in models using nationally aggregated cross sectional data is that the adaptive capacity of unique farms is not captured in the analysis. In order to understand the local effect of climate change on welfare models must capture attributes specific to the study area. Factors that must be taken into consideration include farm characteristics local policy and institutional frameworks (Antle et al. 2004; Mendelsohn, Nordhaus, and Shaw …

Genetic manipulation of crop plants, through breeding or transgenic approaches, for enhanced tolerance to abiotic stress holds great promise for improving yields and promoting new methods for sustainable agriculture. This study examines the potential role that genes of the soybean, Glycine max L., encoding elongation factor-1 alpha (EF-1α) and glyoxalase I (GlxI) might play in response to salt stress. Previous reports have suggested a possible function for both GlxI and EF-1α in conferring enhanced salt tolerance in other plant species. In addition to other possible mechanisms, salt tolerance in soybeans can be regulated by plant uptake and transport of chloride …

Long Term, Continuous Temperature Monitoring Of A Simple Anaerobic Digester And Open Manure Storage Pond In Eastern South Dakota, J. Darrington, E. Cortus
The Journal of Undergraduate Research
A two-cell manure storage system with a cover on the first cell was constructed in the late summer of 2009 in Eastern South Dakota. The covered cell acts as a simple anaerobic digester. Continuous temperature monitoring for 8 months shows the winter effluent temperature equilibrated to around 6°C, and that the effluent temperature trend lagged the ambient temperature trend by a month. Manure composition was also analyzed and was found to be relatively steady throughout the system. Volatile solids were the only component that dropped appreciably across the treatment cell, with an observed maximum of 50% reduction.

Turkish Journal of Agriculture and Forestry
Tomato is one of the most widely produced and consumed vegetable crops worldwide. Plant breeders have usually focused on improvement of horticulturally important traits such as yield, fruit size, shape and colour. With increased attention on human health, however, plant breeders also consider the improvement of health-related traits of fruits and vegetables such as antioxidant characters. In the present study, genes controlling both health-related and horticulturally important traits were mapped in the tomato genome using 152 Lycopersicon hirsutum BC_2F_2 individuals. For this aim, all plants were phenotypically and genotypically characterised and a total of 75 QTLs were identified for all …
