Slant beds for early season cantaloupe production ready for planting. Note how the south-facing bed receives more direct exposure to sunlight. This side of the bed is where seed is planted. The south-facing slant raises soil temperature for quicker germination at a time of year when temperatures can be too low for cantaloupe planting. After the crop is established and before vines run, the top of the bed will be flattened or "knocked down". See 1571762-3 for first pass on bed formation. January 1996 |

nutrient excess or toxicity (general) |
|
Manganese Toxicity on Cantaloupe; Undersides of leaves have water-soaked areas with small, necrotic, raised areas in the center of the water-soaked area. Bronzed, chlorotic areas on the upper leaf surface. Symptoms occur in patches in fields that have low pH. This allows Mn to achieve toxic levels. |
