A tough season at Bourke with a untraditional cold start followed by heavy insect pressure and an extended hot period from Decmber till March. Bolll weights were down under 2 grams per boll and boll numbers were lower than normal. Defoliation was diifficult which exteneded out the season with some crops being picked in July which is very uncommon for Bourke. Yields were back around 2-3 bales/ha. Quality was ok apart from some grade discounts for late picked cotton. The Sicot 714B3F and Sicot 754B3F both looked good in the trial and came out on top.

This season was a tuff one with a cold start, slow early growth and then low retentions caused by insect pressure. The heat made irrigation timing critical and we used more water this year than previous seasons. Heavy heliothis numbers knocked retntions around followed by the heat which caused much fruit loss. Yields significantly down on last year, but two totally different seasons.
