Synopsis Yields of irrigated safflower decreased between 150 and 300 pounds per acre for each 4‐ to 6‐week delay in planting from January 16 to April 23. Seed weight, hull content, linoleic acid content, and iodine values of the oil decreased in the later plantings, while oil content of seed increased. Total irrigation requirements for January, February, and March plantings were similar. Average consumptive moisture use was 34.4 inches, and the peak average daily moisture use was 0.39 inch.
