Special comments/
Spesiale opmerkings
Apart from the improvements in yield, quality and growth, the treated trees produced a harvest 17 days earlier than the untreated, enabling Mr Vlok to realise much better prices by being earlier at the market.
Yield-Plus enabled the treated trees to overcome the effect of the cold spell.
