Effect of Plant Spacing and Insect Management on Burley Tobacco Yields

This document explores the impact of plant spacing on Burley tobacco yields, including calculations for plant populations based on row width and in-row spacing. It discusses how different plant populations affect yield per plant and acre, labor requirements, and returns on management. Insect management strategies are also reviewed, detailing control measures for major pests like aphids and cutworms, relevant application rates, and transplant water considerations. Understanding these factors aids in optimizing crop production and pest control for better farming outcomes.

  1. Transplanting & Insect Management Gary Palmer

  2. Transplanting

  3. Transplanting- Ferris wheel

  4. Transplanting – Carousel

  5. Transplanting - Slide

  6. Plant Spacing • Populations • Row Width • 40 – 42” • In Row Spacing • 22 –24”

  7. Effects of Plant Population on Yield per Plant

  8. Effects of Plant Population on Yield per Acre

  9. Effects of Plant Population on Labor

  10. Effects of Plant Population on Returns to Labor & Management

  11. Plant Spacing • Calculating Plant Population • Space per plant • (Row width x In Row)/144 • Ex. (40 x 22)/144 = 880/144 = 6.111111 • Sq ft per acre = 43560 • 43560/space per plant • 43560/6.111111 = 7128 plants per acre

  12. Effects of In-row Spacing on Plant Population Difference = 3267, if Ten acres = 32,670

  13. Effects of In-row Spacing on Per Plant Yield

  14. Effects of In-row Spacing on Labor Rate per Acre

  15. Yield of Burley Tobacco at Different In-row Spacings

  16. Major Insect Pests

  17. Aphid & Flea beetle Control • Transplant Water • Admire 1 oz/1000 plts • Platinum .5-1.3 oz/1000 plts • Method • Drench • Transplant Water

  18. Influence of Time of Orthene Application on Burley Yield

  19. Cutworms • Transplant Water • Orthene 97 • 3/4 lb per acre • Acephate, Bracket, Orthene 75S • 1 lb per acre • Pre-Plant • Lorsban 15% G • 13.5 - 20 lbs per acre • Lorsban 4E • 2–3 qts per acre

  20. WireWorms • Transplant Water • Admire 2F • 1.4 to 2.8 fl oz / 1,000 plants • Platinum 2 SC • 1.3 fl oz / 1,000 plants
