If you have too much land you will not be able to stop tilling everything in the first year I recommend ally cropping to start. Add more perennial rows each year. The older perennials will need less care after a few years freeing your time to tend to the new ones. Let's face it on a large scale no till only works with herbicide. I practice shallow tilling on my farm with ally crops. The un-tilled tree rows are managed with weed eater and weeding with straight edge shovel. Most orchards use herbicide in the un-tilled area near the trees.
Flooding for extended periods is an ancient form of herbicide. This works in low areas or if you have an impermeable clay or bedrock if you dig trenches and use the soil to raise the growing bed.
