Unfavourable weather patterns and their impact on crop production have again been a major talking point in farming circles. Bizarrely, whilst the total amount of rainfall in 2017 to date is very close to the historic average, it has been distributed in a very unhelpful way (as data from the University’s Meteorology Department weather station helpfully plotted out in an up-to-the-minute annual graph shows).
First and foremost, there was almost no meaningful rainfall for a six-week period spanning the calendar month of April, when crops were going through their most rapid phase of growth. But to compound matters, there was an unusual deluge in the second half of July, when dry conditions would have been more conducive to straightforward ripening and harvest.
Assessing the impact of this latest extreme weather episode was the subject of a BBC South Today news piece I contributed to on Tuesday evening. The research team I am leading in the School of Agriculture, Policy and Development may have some answers. We designed a large field experiment designed both to quantify yield losses due to drought and to detect varieties with drought-beating characteristics.
