In contrast to most other dryland crops the cotton at “The Point” was planted into quite good moisture but as usual conditions were very cool for several weeks. The cotton was slow to develop a plant stand of 3 to 4 plants per metre.
A relatively hot dry summer kept the crop size down and promoted early maturity. The hot summer also influenced variety performance -favouring the full season types. Although Sicot 74BRF produced the highest yield we recommend Sicot 71BRF for the far upper Namoi region. Fibre quality was all good however micronaire values were on the high side. This is very unusual in the part of the valley.

This was our hottest and driest summer for a very long time. Record high temperatures in January challenged all our summer crops. But in general the cotton handled the heat better than our sorghum. The crop maintained very high fruit retension and this combined with the lack of useful rain in January and early february produced a very short plant type.
The crop was planted into a very dirty field that required 3 full rate Roundup sprays to control the weeds. Insects were quiet. There were no sprays for insects and no Pix required.
Although the yield was well down on average we were happy with result given the lack of rain.
