TIPS FOR NO-TILL COTTON PRODUCTION

Field Selection
• Same as conventional tillage.
• Control erosion using waterways, rows  on contour and filter strips.
• Subsoil if tillage pan exist and/or extreme traffic has occurred.
• Avoid land with heavy infestations of perennial grasses and vines.
Vegetative Cover
• Cover crops may be needed if crop residue is inadequate.
• Small grains, especially wheat is preferred.
• Excessive growth can interfere with planting, emergence and growth.
• Do not plant until cover crop and weeds are dead.
• Delayed termination of host weeds may increase incidence of early-season pests.
Fertilizer and Lime
• Soil test same as conventional.
• Adjustment for cover crop may be necessary

Weed Control
• Kill vegetation prior to planting.
• 2,4-D at least 30 days prior to planting will improve control of some winter annuals.
• May require two burndowns.

o First, at least two weeks prior to planting.
o Second, can be applied at planting.
• Identify weeds in seedling stage.
• See Roundup Ultra and Gramoxone Extra labels for rates on specific weeds.
Planting Equipment
• Use conservation tillage or no-till planting equipment.
o Heavy duty down pressure springs.
o Tool bar weight brackets.
o Double-disc or offset double- disc openers.
o Heavy duty press wheels.
• Plant 4 to 5 mph
• Use coulters if the planter does not have double disk openers.
Planting
• Soil temperature 68F for three consecutive days with a favorable five day forecast.
• Planting may be delayed if crop or residue is dense.
• Plant seed ¼ to ½ inch deep.
• Good closure of seed furrow can help ensure a better stand.
• Plant stands may be reduced – plant ½ to 1 seed per foot more than conventional.
