Plan ahead for crop rotation. It's hard, but that's a way to get more food per square yard.
When the spring cool-season crops are winding down, the summer crops might even be inter-planted.
Try to get fall crops planted ASAP as summer crops are winding down.
Covering part of the bed with hoops and plastic might get your spring crops mature 2-4 weeks earlier. They might let your fall crops last a month opr more into the winter.

Simple, thrown-together plastic irrigation gadgets can save a lot of water and give roots much more consistent moisture, especially in sand. Dripline is pretty easy to lay down. Dripline would be suited to watering with MINIMUM water, but keeping the root zone moist.
They can pay for themselves in saved water and increased yield. If the time you would have spent dragging a hose around and spraying leaves is redirected to some other gardening activity, like a plot twice as large, you could have a lot more yield.
I found the mini-jet sprayers to be easier to set up, but they waste as much water to evaporation as a hose.
