Central Highlands grain grower Warrick Stent-Smith is one of the farmers taking advantage of the recent rainfall in the district by planting more than 1000 hectares of mungbeans this season.

Mr Stent-Smith, Roper View, Wyuna, and his father Alan, have been dryland grain growers in the Emerald region since 2008.

They've just finished planting 500 hectares of mungbeans on January 18, with another 500 hectares expected to go in from mid-February.

The Stent-Smiths received 60 millimetres of rain at the start of November last year and a further 125mm over the Christmas holidays at their property, 23 kilometres out of Emerald.

Mr Stent-Smith said this season was the earliest they've planted mungbeans.

"The planting season started off really well and we've had early rain, which gives us a bit of moisture to plant into," Mr Stent-Smith said.

"We've planted earlier this year just because of the rain.

"If you don't get the rain at the right time, that's probably our biggest challenge as a dryland farmer."

This season 90 per cent of the crop planted was Jade and the remaining 10pc was Crystal, with planting taking place at a rate of 24 kilograms of seed per hectare.

Mr Stent-Smith said they've doubled their plant this year, due to the favorable prices in the mungbean market.

"We thought we would get in early for those early contracts while they're at a higher price and take a bit of a punt this year and put a bit more in then usual," he said.

"Because we're planting more this year, we decided to space the planting times this season to spread the risk, in case we don't receive any follow-up rain.

"It takes the pressure off at harvest time so there's not a large area coming in at once."

The Stent-Smiths forward sold some of their mungbeans, which are expected to return $1350 per tonne.

The Stent-Smiths are planning to rotate their other fallow fields into chickpeas this winter.

Mr Stent-Smith said Feathertop Rhodes was a growing concern, which they're managing with minimal till practices and Dual Gold herbicide.

Central Queensland farmers are edging closer to finishing planting their summer crops as their growing window begins to close.

Growers are planting into moisture following decent rainfall during the Christmas holidays.

In the Central Highlands, growers are holding out hope for follow up rain to bolster their moisture content going into the season, with hopes yields will be above average.

AgForce Central Queensland grains board member Jordan Anderson, Avonmore, Theodore, said the optimal planting window was beginning to close.

"It's normal planting season for us and we're at the sweet spot now for the planting window," Mr Anderson said.

"It's not late in central Queensland, but in the southern Darling Downs that's definitely late.

"We obviously get a lot hotter up here compared to down south and we have crops that begin flowering and grain filling out in February."

Central Highlands growers have been planting, mungbeans, millet, sorghum, dryland cotton and corn.

Mr Anderson said the bulk supply of grain continues to affect the price and demand for sorghum.

"Grain prices are heavily dependent on feed numbers, and also grain supply to feedlots," he said.

"There's a lot of grain around, which softens the prices, compared to the last three years where there has been no supplier."
