Clones need to exhibit high yield and freeze tolerance. Far north Texas growers may need Cynthiana or hybrids because of freeze and disease resistance. In deep sand SO4 or 5C could be used for nematode control. In high pH soil FerCal or 41B could be used for preventing iron chlorosis. Hotwater treated Champanel may be used for Cotton Root Rot.
Mechanical harvesting is the key to the future in Texas.
A high wire Single Curtain is a low cost system, can give high yields, and is adapted to mechanical pruning and harvesting. Bilateral Cordon has been used well for 20 years. Quadrilateral Lyre for vigorous soil is a large VSP system which can give both yield and quality. High density Guyot VSP used in Europe must be limited to low vigor soil in Texas.
