Elba, New York

Variety:  unknown

Vitazyme application:  (1) 13 oz/acre in the furrow at planting, with starter fertilizer and a fungicide;  (2) 13 oz/acre over the leaves and soil at the 3 to 4-leaf stage;  (3) 13 oz/acre over the leaves and soil at bulb initiation.

Comments:

Time of Vitazyme use:  5 years

Farmer:  "We're very satisfied with Vitazyme.  We farm mostly mineral soils, and they are easier to work and have better drainage than when we first started the program.  We have had good crops in two difficult years when others didn't.  We grow mostly jumbo-sized onions, and Vitazyme really helps them obtain that size.  It's a big benefit."

Fertilization:  a balanced program with the regular use of cover sprays and foliar sprays
