  2. ADOPT Project – SVGA and U of SAlternative Strategies for Establishing Garlic Standard approach is to plant cloves Many cultivars only have a few cloves per bulb Results in v. high seeding costs Difficult to mechanize planting

  3. ADOPT Project – SVGA and U of SAlternative Strategy … Use bulblets to establish the crop Each plant produces 10-200 bulblets, depending on cultivar Bulblets are easy to harvest, store well and their round shape makes them easy to machine plant.

  4. ADOPT Project – SVGA and U of SUsing bulbils to establish garlic … Some questions … - will fall-seeded bulblets overwinter? - how well will the bulblets grow? - what kind of yields can be expected? - what quality can be expected? - will it take 2 years to produce standard size bulbs?

  5. ADOPT Project – SVGA and U of SUsing bulbils to establish garlic … Summer 2012 … - harvested bulblets from “Music” garlic - planted (using disk planter) in fall 2012 - covered plot with straw in late fall

  6. ADOPT Project – SVGA and U of SUsing bulbils to establish garlic … 2013 … - 70% of bulblets survived (vs 69% for fall planted cloves) - small plants from bulblets struggled to compete against weeds .. hand weeding required - yield increase when planting … cloves … 6:1 bulbils … 16:1 - crop resulting from bulblets was all “rounds”

  7. ADOPT Project – SVGA and U of SUsing bulbils to establish garlic … 2013 … Bulblet production by garlic cultivars along with impact of scape removal on bulb weight.

  8. ADOPT Project – SVGA and U of SUsing bulbils to establish garlic … Fall 2013 … - establish 6 stiffneck cultivars using either cloves or bulblets - cloves hand planted – while bulblets were planted using a disk seeder - mulched with straw in late fall

  9. ADOPT Project – SVGA and U of SUsing bulbils to establish garlic … 2014 … - 100% reliance on herbicides for weed control … Chateau (pre-emerge) followed by multiple applications of Goal

  10. ADOPT Project – SVGA and U of SUsing bulblets to establish garlic … 2014 …

  11. ADOPT Project – SVGA and U of SUsing bulbils to establish garlic … 2014 …

  12. ADOPT Project – SVGA and U of SAlternative Strategies for Establishing Garlic Bulblets are … - far less costly to plant than cloves - better suited to mechanical planting - capable of overwintering - require extra weed control - have a much higher yield multiplier than cloves - some cultivars will produce a small cloved bulb in a single season

  13. ADOPT Project – SVGA and U of SUsing bulbils to establish garlic … Fall 2014 … - establish 6 stiffneck cultivars using either cloves or bulblets - cloves hand planted – while bulblets were planted using a disk seeder - mulched with straw in late fall

  15. ADOPT Project – SVGA and U of SUsing bulbils to establish garlic … 2015 … - 100% reliance on herbicides for weed control … Chateau (pre-emerge) followed by …… - Buctril for emerged broadleaf weeds - Poast for volunteer grain from straw mulch

  16. Buctril/Poast damage to garlic

  17. Herbicide damage resulted in 100% loss of the 2015 garlic planting
