Cotton - deficit drip irrigation, ealy Pima harvest

Drip irrigation is rapidly gaining popularity in cotton grown in California's San Joaquin Valley. Field trials conducted by University of California Cooperative Extension Cotton Specialist Bob Hutmacher suggest that water cutbacks during specific times of the growing season can save 3-4 or more inches of water per crop. 

Research by UCCE Farm Advisor Steven Wright, Tulare and Kings counties, indicates that Pima cotton can be defoliated a week or more earlier - before the traditional 3-4 nodes above cracked boll - without much impact on lint yield and quality.
