Macquarie River Food and Fibre (MRFF) estimates the gross value of the more than 40,000-hectare crop will exceed $250 million.

In a statement released this week the peak body for irrigators in the valley reports of better growing conditions forcing members to "rely more on their irrigation entitlement", anticipated higher yields and flow-on benefits to the region.

MRFF executive officer Susan Madden confirmed a similar area had been planted with cotton this season to the one before.

"Just over 40,000 hectares was planted to cotton this season, which is similar to the area grown last year," she said.

"However the warmer and drier season provided better overall growing conditions so we are anticipating higher yields across this year's crop."

Ms Madden said drier conditions during summer required growers to rely more on their irrigation entitlement.

"The industry used around 370,000 megalitres this season, which accounts for about one-third of the total releases made from Burrendong Dam since July 2012, she said.

MRFF reports in the same period 700,000 megalitres had been released for flood mitigation, environmental flows and town water use.

Ms Madden said water used for irrigated agriculture has significant flow-on benefits to the region.

"The stats tell us that 1000 ML (megalitres) used for cotton production supports 1.3 jobs, so we're talking about the creation of 500 farming jobs across the Macquarie Valley during the growing season," she said.

MRFF reports of a busy time ahead for cotton growers.

"The hive of industry activity is set to continue in the Macquarie over the next few months as the crop is harvested, transported and processed in the valley's four cotton gins," Ms Madden said.
