Onion Crop Growth Stage and Status Last Modified: 07/24/13

The spring sown-crop onion crop is now at growth stages 8-10 and harvest season is near its end.

Bulb yields and quality have been good as environmental conditions have been ideal. This will

be the final report from New Mexico for this year.


Weather Impacts (temperature, rain, hail, freezing) Last Modified: 07/24/13

Temperatures have been unseasonably cool (mid to high 80s) and chances of precipitation have

increased. The monsoon season has begun and recent precipitation may delay harvest slightly in

some areas.
