Yield Tonne / Ha

Two applications of SM6 increased total yield and proportion of over 50mm onions. After six month’s storage, the bulb quality was excellent and those bulbs treated with SM6 were better in terms of bulb brightness and skin thickness.

Financial Results (2012 prices):

Assuming £260 per tonne for onions greater than 50mm and £130 per tonne for those smaller, then SM6 gave an increase on return over the average control of approximately £434 per hectare.
