To determine the yield differences between no drainage or irrigation and four other water management systems: sensor-based sub-irrigation, controlled water table, tile drainage, and manual sub-irrigation. We also evaluated the yield performance of two different genetic families, one possessing an improved ability to handle moisture stress.

Sensor Controlled Sub-Irrigation vs. Manual

CAN TILE WORK FOR MORE THAN JUST DRAINAGE?

We evaluated both draining the soil profile during the wet times of the season and recharging the water table when it became hot and dry. The tile in this portion of the plot is set up on 15 ft. widths that follow the contour of the ground. This allowed for maximum drainage and improved water movement through the soil profile.

There were uniform, increased plant stands and improved plant health compared to the control.

The tiled area dried out 1 to 2 days sooner, allowing for earlier planting than most plots on the farm.
