Best Management Practices For Corn Production In South Dakota: Tillage, Crop Rotations, And Cover Crops, Dwayne L. Beck, David E. Clay, Kurtis D. Reitsma

SDSU Extension Circulars

Historically, tillage and cultivation were used to manage residue, diseases, insects, weeds, and soil compaction. Tillage equipment that has been used includes molderboard plows, discs, cultivators, rippers, and chisel plows. Conservation practices and innovations in production tools (i.e., planters, herbicides, and genetically modified crops) provide farmers with the opportunity to minimize losses.

Best Management Practices For Corn Production In South Dakota: Seasonal Hazards—Frost, Hail, Drought, And Flooding, Robert G. Hall, Todd P. Trooien, Dennis P. Todey, David E. Clay

SDSU Extension Circulars

Conclusion: Weather conditions such as frost, hail, flood, or drought can severely reduce yields. Effects from these events are manageable to a certain extent, but loss can be expected when these events occur. The degree of loss depends on the severity of the event. Crop insurance has become a common component of corn production in the U.S.; the insurance provides the producer economic protection for uncontrollable events. Producers should consider crop insurance based on the consequences of crop loss.

Best Management Practices For Corn Production In South Dakota: Corn Planting Guide, Robert G. Hall, Kurtis D. Reitsma, David E. Clay

SDSU Extension Circulars

Obtaining maximum profit from a corn crop depends on the timely planting of an appropriate hybrid, at the proper depth, with a planter that evenly spaces the seed. The success of a corn crop is dependent on equipment maintenance, seedbed preparation, the development of a sound fertility and pest management program, and planting the seed. Early planting is best, but temperatures should be warm enough to assure quick germination and emergence, and late enough to avoid hard frosts. Planting-opportunity windows can be narrow due to spring rains or a late warm-up. Time spent in the off-season maintaining equipment and planning …

Best Management Practices For Corn Production In South Dakota: Corn Growth And Development, Kurtis D. Reitsma, Sharon Clay, Robert G. Hall

SDSU Extension Circulars

Corn growth is influenced by cultural practices and available natural resources. The rate of growth and development changes during the season (fig. 1.1). In South Dakota, water and nitrogen (N) are important resources that limit yield. Other factors that reduce yield include disease, insects, weeds, and deficiency of other plant nutrients. For example, disease and insect infestations can reduce water and nutrient uptake or severely damage the plant to the point of yield loss. Weeds compete with the crop for water, nutrients, and light. Stress from temperature and water extremes affects nutrient availability, often increasing pest population and occurrence and …

Population Reconstruction Model To Analyze Harvest And Banding Data For Mourning Doves In South Carolina, Christopher Chumbley

All Theses

Mourning dove (Zenaida macroura) call count indices for South Carolina indicate a negative trend over the past 42 years (1.2% decline per year, p < 0.05). Total harvest estimates in the state increased from 2003-2007. Banding data from doves banded in South Carolina and data from annual examinations of harvested mourning dove wings during 2003-2007 were collected and analyzed. Data sets used contained 6,600 banded doves and 21,240 harvested dove wings. Survival estimates from band recovery analyses for adult and juvenile doves were 0.44 (± 0.04 SE) and 0.35 (± 0.06 SE), respectively. Survival rates were constant from year to year while recovery rates differed annually for adults and juveniles. The average natural mortality estimates for adults and juveniles in the presence of hunting were 0.45 ± 0.122 and 0.47 ± 0.189, respectively, during the study period. The average harvest and kill rates for adults and juveniles were also estimated. Age-at-harvest ratios adapted from annual wing examinations during the harvest were used with recovery rates to derive estimates of annual productivity in the population. Linear regression analysis of productivity estimates found a significant decline in productivity during 2003-2007 (-0.21, p < 0.10). The average productivity estimate was 1.43 (± 0.33 SE) juveniles per adult and the estimated productivity required to maintain a stable population was 1.60 (± 0.30 SE). The effects of constant survival rates, varying hunting mortality estimates and declining productivity estimates were discussed in relation to breeding populations in rural areas of South Carolina.

Corn diseases can be separated into 1) seed and seedling diseases, 2) root-infecting nematodes, 3) leaf diseases, 4) rusts, 5) stalk rots, and 6) ear and grain molds. Yield losses can result from diseases directly reducing yields or from harvestability, spoilage, or marketing and/or use issues associated with mycotoxin contamination. See Table 9.1 for corn disease management information. Attention to optimal seed quality, hybrid selection, seed treatments, weed and insect control, crop rotation, soil fertility, irrigation, and prompt harvest can reduce disease impacts. This chapter discusses aspects of recognizing and managing South Dakota corn diseases.

Evaluation Of Streptomycetes For Biological Control Of Gummy Stem Blight Disease Of Cantaloupe, Shima Chaudhary

Theses and Dissertations - UTB/UTPA

Studies were conducted to evaluate the efficacy of Streptomyces isolates for the biological control of gummy stem blight (GSB) in cantaloupes (Cucumis melo var. ‘Primo’) in south Texas. Plants were monitored for seedling emergence, lesions, mortality and plant growth under laboratory, greenhouse and field conditions. Comparison of treatment groups indicated a significant reduction in plant mortality and enhanced growth of infected plants exposed to three Streptomyces isolates (MA1F4#2, WI1B#5, and MA2A4 #2), which appear to be most effective when used in combination. In all three experiments, GSB infection was associated with a significant reduction in reflectance of near-infrared wavelengths (700-1,100 …

On-Farm Energy – Can We Make It Work?, William L. Booker

Panhandle Research and Extension Center: Press Releases

The volatility of the biofuels industry has created another reason for farmers to consider producing “on- farm energy.”
Producing biofuel on the farm has the potential to help farmers become more independent by developing a more stable and secure fuel supply, as well as benefit the environment and prolong equipment life. But first they must study and understand the process, the risks, and opportunities.
As little as a year ago, biodiesel production was expected to rise rapidly, as it had for several years. But the sudden fall in crude oil prices changed the direction of the production curves.
