Pre-harvest samples were taken from the four pea paddocks on 16 January. They show a wide range in crop maturity and yield expectations.
Four 1 m2 samples were taken in each half hectare paddock. We counted plants, weighed the fresh vine and took it to the McCain Foods mini viner and tenderometer for processing. Each sample was processed, peas weighed and TR tested.
Indicative tonnages averaged for each paddock range from 4.2 to 5.6 t/ha and tenderometer readings from 86 to 105. Within this, there is an even greater range reflecting the variability noted across the region. The lowest sample tonnage was 3 t/ha and the highest 6.8 t/ha. Notably, these were from the same paddock. The lowest TR readings were 78 and the highest 113.
Paddock 2 has buried drip irrigation. It has a much bigger canopy – 39 t/ha fresh weigh compared to the 26 t/ha average of the other paddocks. This paddock is slower maturing, still flowering where others stopped some time ago. While it has the lowest mean TR reading, it has about the average yield at present. If left to get to equivalent maturity, the yield could be close to the higher end of our four paddocks.
