Australian Rainfed Cotton has been grown with startling results over the last 10 - 15 years. We have had some growers in the more favoured areas averaging over 2 bales/ acre while growers in more marginal areas have left the industry due to unprofitability. As the bulk of our crop has always been irrigated, the largest part of the research dollar has been spent on irrigated cotton. Rainfed cottongrowers have largely taken this data and used it directly on their farms. In more marginal situations this would appear to have some drawbacks.
