Results and Discussion 2017
Stem Numbers and Tuber Set
Application of ALBIT increased stem number of Canela Russets from 2 stems per plant to 3 stems per plant. Tuber set of Canela Russets was increased from 7 tubers per plant to 8 and 10 tubers per plant for “foliar only” and “in-furrow + foliar” treatments, respectively.
This finding is very significant for Russet potatoes that have a drawback of producing fewer stem and tuber numbers.
“Foliar only” treatment enhanced tuber bulking, as evidenced by the increased tuber fresh weight at the mid to late tuber bulking stage [from 100 days after planting (DAP).
Tuber Yield and Tuber Size Distribution
Total and marketable tuber yields responded positively to supplemental ALBIT application. Application of ALBIT increased total tuber yield by 8% and 4%, for “foliar only” and “in-furrow + foliar” treatments, respectively. “Foliar only” application of ALBIT increased marketable (> 4 oz.), large size marketable (> 6 oz.), and medium size (4-10 oz.) tubers by 9%, 7%, and 16%, respectively.
Application of ALBIT resulted in no tuber external defects in this study. Where no ALBIT was applied, it was observed that 1.1% of the tubers showed external defects. Tuber specific gravity was not impacted by the treatments in this study.
Bulk Marketable Result
