| Conclusion/Gevolgtrekking |
Better growth and increased yield on
Yield-Plus treated trees |
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. |
