Maximizing yield of high quality cottonseed through nutrient management strategies
… The prevailing temperatures provide marginal heat unit accumulation during the early and latter parts of the growing season. The cool temperatures in September and October limit the maturation of both the seed and fiber of bolls resulting from flowers in mid-August. The nutrient supply, …

Factors governing zoysiagrass response to herbicides applied during spring green-up
… prevailing temperatures surrounding application, heat unit based application timings, and spray penetration into zoysiagrass canopies as possible contributors to zoysiagrass injury. The results indicated that a wide range of herbicides may be safely used in dormant zoysiagrass. However, as …
