The decision to re-seed is not an easy one, especially this far into June. Ultimately it is the growing conditions for the remainder of the season that will determine if the decision to re-seed was correct. If you have made the decision to re-seed, leave a checkstrip, preferably in the centre of the field. This provides an easy way to get replication so at harvest you can make a yield comparison between the area not re-seeded and the two re-seeded areas on either side. The results of this on-farm experiment may be very valuable when wrangling with future re-seed decisions.
