Best economic benefits come from renewing underperforming pasture early in the season – simply because early sown pastures spend less time as ‘poor’ producers and more time as ‘good’ producers.
An example of this is from Willsden Farm, owned by the Camden Group at Te Pirita (presented at field day 21 October 2014) which showed Tabu Italian ryegrass spray/drilled a month earlier in spring to grow 0.8 t DM/ha more, with an extra value of $160/ha (assuming a $3.85/kgMS payout).
