Double cropping with wheat is the most popular no-till system in Mississippi. Planting an early maturing grain crop, harvesting the grain at high moisture, and using no-till planting can help minimize the soybean yield reduction due to double cropping. Your county Extension office has a detailed publication on double-cropping systems. When planting after ryegrass or other winter grazing crops, you may need some tillage to break the compaction layer. No-till yields are comparable to conventional plantings, but the major influence is early season weed control and environmental conditions.
Varieties Select a variety adapted for the soil and location regardless of tillage.
Since weeds are usually a concern, plant a variety adapted to your particular soil type and row spacing. For minimum till systems where cultivation is planned, use a row width that will allow for the movement of tractors and cultivators. Many producers are placing a planter unit behind the tractor tire hopefully to get enough of a stand to help suppress weeds. For no-till, plant in as narrow a row as possible to provide the most shade in the fastest time. If planting in hard soil or other poor seedbed conditions, you may need to plant 10 to 15 percent more than you would with conventional planting.
