Arkansas

Irrigated fields outyielded dryland fields by 11.6 bushels per acre.

Raised beds outyielded flat by 1.4 bushels per acre.

Raised irrigated outyielded flat irrigated.

Group 4s provided 3.6 bushels more than Group 5s.

When both maturity groups were joined, planting date was best at May 1 through 16. Separately, Group 4 yields were maximized when planted April 16 through April 30. Group 5s did best when planted May 17 through May 31.

The highest yields were on 12-inch to 19-inch row spacings.

The optimal plant population was 100,000 to 140,000.

Louisiana

Irrigation didn't mean as much as in the other states, providing a 3.5-bushel bump over dryland.

Raised beds provided a half-bushel increase over flat ground.

As expected, raised/irrigated outyielded flat/irrigated.

Group 5s outyielded 4s by 1.3 bushels per acre.

Plantings for both Group 4s and 5s were best between April 16 and April 30.

Highest yields were obtained on 7-inch to 12-inch row spacings.

Optimal plant population was 100,000 to 120,000.

Mississippi

Mississippi had the biggest response to irrigation: 16.8 bushels per acre more than dryland.

Raised beds provided 2.5 bushels more per acre over flat land.

Group 5s were 11.9 bushels better than Group 4s.

When the Group 4 and 5s were combined, April 16 was the best planting date. When separated, Group 4s were best planted between April 1 and April 15. For 5s, the best were planted April 16 though April 30.

Highest yields were obtained on 12-inch to 19-inch rows.

The best final plant population was in the 100,000 to 120,000 range.

Tri-state

Irrigation was successful across the three states. “When you average the states over five years, it's a 12.2-bushel increase with irrigation.”

Raising beds provided producers an additional 1.5 bushels.

Group 5s provide a 4.6-bushel advantage over 4s.

Planting Group 4s and 5s is best in the April 16 through April 30 window.

Row-spacing is best at 12-inches to 32-inches.

The best final plant population is between 100,000 to 120,000.
