Independent field trials have shown for a 4th year that Interagro’s amino acid + peptide biostimulant Bridgeway helps to combat the effects of heat stress in potato crops, enabling photosynthesis and tuberisation to be maintained.
Importantly for growers, it helped secure yield with significant increases and margin gains over untreated crops achieved in all the trials over the 4 years.
Keeping potatoes stress-free is not an easy task, with crops often subjected to prolonged heat stress periods at key growth timings.
The replicated trials conducted by CMI Ltd in 2017-2019 and Green Crop Information (part of Dyson Farms) in 2021, showed that mean temperatures regularly exceed the optimum of 20ºC, impacting the rate of tuber bulking and final yield.
The trials investigated the influence of different application timings and sequences of Bridgeway on the growth and yield of potatoes. Regular test digs showed heat stress slowed the rate of tuber bulking in untreated crops, whilst in potato crops treated with Bridgeway, bulking was maintained and this led to significantly higher yields by the end of the season. In fact tubers reached marketable yields faster, enabling burndown to start sooner.
