COMMERCIAL SWEETPOTATO PRODUCTION IN MISSISSIPPI AgEcon
Parvin, David W., Jr.; Walden, Charles; Graves, Benny.
This report provides an estimate of selected costs incurred in sweetpotato production in Mississippi, 1999. Land, management and general farm overhead costs were not included. Per acre returns above specified costs are estimated at approximately $1,100.00 per acre.
Tipo: Working or Discussion Paper Palavras-chave: Sweetpotatoes; Production costs; Net returns; Cash flow; Price sensitivity; Equipment; Chemicals; Production Economics.

Competitive Relationship of Three Warm-Season Turfgrass Species AgEcon
Adrian, John L., Jr.; Duffy, Patricia A.; Lloyd, Michael.
The competitive position of three warm-season turf species commonly grown in the South (bermudagrass, centipedegrass, and zoysiagrass) is evaluated for a farm with 100 acres available to allocate to turfgrass-sod production. A multiperiod linear programming model is used to determine optimal mixes of grasses and resulting net returns for a seven-year planning horizon. Within current observable price ranges, variation in the prices of the different grasses has little impact on the profit-maximizing combination of grasses. Bermudagrass, with the shorter production cycle and positive influence on cash flow, dominates the higher-valued, longer-production-cycle alternative grasses. Availability of initial money capital from internal sources does not alter the...

Economic Effects of Bovine Respiratory Disease on Feedlot Cattle during Backgrounding and Finishing Phases AgEcon
Brooks, Kathleen R.; Raper, Kellie Curry; Ward, Clement E.; Holland, Ben P.; Krehbiel, Clint.
This research examines the economic effects of bovine respiratory disease (BRD) on backgrounding and finishing phases of cattle production. This research measures the effectiveness of using serum haptoglobin (Hp) concentration to predict BRD occurrence and the impact of multiple treatments for BRD infection on cattle performance and returns. During the backgrounding phase, 222 heifers were grouped by Hp level. After the backgrounding phase, 193 heifers were then grouped by number of BRD treatments in the finishing phase. Net returns decreased in the backgrounding phase and the combined phases as the number of BRD treatments increased. Hp concentrations had no significant effects on net returns.
Tipo: Conference Paper or Presentation Palavras-chave: Bovine respiratory disease; Haptoglobin; Net returns; Livestock Production/Industries; Production Economics.

Spatial and harvesting influence on growth, yield, quality and economic potential of Kalmegh (Andrographis paniculata Wall Ex. Nees) JARTS
Kumar, Sanjeev; Kumar, Anil.
Andrographis paniculata, commonly known as Kalmegh, is used both in Ayurvedic and Unani system of medicines because of its immunological, antibacterial and hepatoprotective properties. This study was carried out to investigate the influence of four harvesting times (120,135,150 days after planting and at seed maturity) and four planting distances (30×15, 30×10, 20×15 and 20×10 cm) on growth, dry herbage biomass, seed yield and quality traits of Andrographis paniculata at CCS Haryana Agricultural University, Hisar, India in the two years 2005 and 2006. The treatments were laid out in a split plot design with three replications. The maximum values for dry herbage biomass yield (5.14 t ha^(-1)), net returns (760.00 EUR ha^(-1)), B:C ratio (2.59),...
