Abstract (sommario):

Cottonseed was treated with several fungicide treatments in an effort to protect the seed and seedling from disease. Seed germination and vigor was evaluated in three Arizona locations; Maricopa, Marana, and Safford. Stand counts were taken after emergence at all three locations and percent emergence (PEM) was calculated. Significant differences in percent emergence due to seed treatments were observed in the both sample dates at Marana. Maricopa and Safford showed no statistically significant differences due treatment.

Abstract (sommario):

Six different seed treatments and one in furrow granular treatment were used in a field with a history of black root rot, caused by Thielaviopsis basicola. The treatment was a follow-up on the study done the previous year (1). Stand counts, root lengths and seed cotton yields were taken to see if any of the treatments increased stand counts or stimulated root growth. Thielaviopsis was not isolated in the plants this year, so the effect of the fungicides on this pathogen were not evaluated. Stand counts were, however, significantly influenced by the seed treatments.

However, it was also found that soybean yield at five of the localities was reduced on average by 8% after Mo seed treatment. It was surmised that the yield reductions observed after Mo seed treatment were connected to the quality of the seed used for planting.

Agriculture consistently remains one of the most hazardous industries. Hazards exist not only on farms, but also within pesticide manufacturers and distributors. Treating seeds with neonicotinoid insecticides is an important strategy to address pest problems. Neonicotinoids are a systemic insecticide that transfuse throughout the entire plant from roots to pollen. While research on the environmental effects of neonicotinoids is growing, research examining the potential adverse effects on humans is in its beginning phases.

Abstract (sommario):

Natto and sprout soybeans are produced using small-seeded soybeans and their production is a high value alternative to grow grain soybeans for food in U.S. The development of soybean cultivars with improved natto and sprout quality is crucial for maintaining and increasing the soyfood market. However, there is insufficient information on sprout soybean characteristics. Therefore, the first objective of this study was to evaluate seed and sprout traits as potential selection criteria and study the storage effect on sprout quality. Seeds can be a vehicle for transmission of pathogens capable of

Abstract (sommario):

Dectes texanus LeConte (Coleoptera: Cerambycidae) is a longhorn beetle species endemic to eastern United States. Originally described as a pest of weeds from the family Asteraceae, D. texanus has expanded its host range and is found infesting the stems of soybeans, Glycine max (L.) through the southwestern and middle United States. Female D. texanus chews a hole in the epidermis of a petiole and oviposits on it. Then, the D. texanus larva depletes all the pith of the stem making a tunnel down to the base of the plant and girdle the stem about 5 cm above the soil line. When a force is applied t

Abstract (sommario):

The response of several plant species to heavy metal contaminated soils was evaluated using plant bioassays with a soil substrate. A natural soil was collected from Dinwiddie County, Virginia and soil analysis was performed. The plant species, Lolium multiflorum, setaria italica and Trifolium rep ens latum, Robinia pseudoacacia, Andropogon gerardi, Asclepias syriaca, Echinacea purpurea, Rudbeckia hirta and Festuca rubra were grown in to determine the response to cupric and cadmium chloride in soils (mg Cu/kg soil). A few plant species were grown in small pots in a plant growth chambe

Abstract (sommario):

The aim of this master thesis study was improvement of the required operational conditions for aerobic granulation in sequencing batch reactors (SBRs). In the first part of the study, membrane bioreactor sludge (MBS) and conventional activated sludge (CAS), were used to investigate the effect of suspended seed sludge type on granulation in SBRs. The MBS granules were found to be advantageous in terms of size, resistance to toxic effects, stability and recovery compared to CAS granules. During non-inhibitory conditions, sCOD removal efficiencies were 70&plusmn<br>13% and 67&plusmn<br>11% for M
