Soil type variability caused one side of the trial to yield much higher than the other. As a result of this I am a bit sceptical about its reliability.
The field was long fallowed out of chick peas from the 2016 winter. Preparation was ideal with no stubble issues and the usual good seed bed resulting from a chick pea rotation.
The field was watered up on the 10th October and got a heavy 23mm on the 12th which put the entire field under water. The crop emerged well despite this. This field continued to get under storms for the rest of summer despite it being a dry summer throughout the district. There was a total of 243mm effective in crop rain with several of the bigger falls occurring soon after irrigations. The crop did not show any sign of water logging however I suspect the rain events may have impacted the final yields to some degree. Yield data showed much better cotton on the head ditch than the tail drain which could be a result of the big rain events.
Apart from storms and some minor hail damage on the 18th November the crop suffered no other setbacks and picked cleanly on the 3rd of April.
The 714 was ready to defoliate about 10 days before the 748 and could have gone without the last irrigation.
