Quality of the bean was
substantially improved - thus realising a better
return - an average of 6.4 tons/ha gain.
A longer harvest resulted in higher prices for
the later harvest. |

Mr Vlok recons he should have
increased the quantity of Yield-Plus used and
done a third spray and wishes he had sprayed more
area. |
