Objectives: Covercrops have been used for many years to improve soil quality, as a source of nutrients, improve water infiltration, suppress weeds, harbor beneficial insects, control nematodes, etc. Little work however has been directed towards their use in a cotton rotation. This study was initiated to investigate four fall-planted covercrop species on subsequent cotton growth.
Procedures: Fescue, annual rye, hairy vetch, and subterranean clover were planted on beds on November 14, 1989. The field was irrigated…

OBJECTIVES: Minimum tillage has received attention in recent years as a technique to reduce production costs, improve soil quality, and reduce erosion. This study was initiated to evaluate the effects of minimum tillage on cotton growth and soil quality.
PROCEDURES: The 1990 study was conducted at the U.S. Cotton Research Station in Shafter, CA. The treatments were established in a barley field prior to grain harvest. The~barley had…

OBJECTIVES: To develop the criteria for ‘best practice’ cotton production systems. To test experimental component subsystems and the interrelationship of cotton production subsystems including rotational crops. To demonstrate for technology transfer ‘best practice’ systems.
PROCEDURE: Four systems were identified for inclusion in a field study resulting from a factorial of two systems categories: row spacing and tillage. The ‘best practice’ row spacing was selected as 30 inch as compared…
