Summary Not Available – First paragraph follows:
Benefits of “precision tillage” or deep tillage directly under the drill row for cotton were generally substantiated in the fourth year of San Joaquin Valley trials. Substantial increases in cotton growth, yield and earliness were obtained on coarse-textured soils at the U. S. Cotton Research Station, Shafter, and in Madera County tests. However, precision tillage trials on fine-textured soils in Tulare County did not show these benefits.
