ONE thousand tonnes of grain was harvested from 110 hectares of corn on Bruce Derrick's Bogaroo of Bruce Derrick, at Kupunn last season.
Mr Derrick said corn was a crop he grew each year and last season it consisted of the Pioneer hybrid 31G66 and Pioneer hybrid 32P55.
He said the yields of both were pleasing; particularly considering the entire crop was inundated by hail just after it emerged from the ground.
"It was at about the two to four-leaf stage and it received a fairly heavy hail storm and there was a lot of ice on the ground," Mr Derrick said.
At the time there was concern as to whether the crop would recover, but despite the adverse conditions, the corn recovered well and grew strongly in the weeks that followed.
"It did well to go around that 10 tonnes per hectare mark," he said.
Cotton is the main summer crop grown on the property each season, with corn grown each year as an alternative option and for rotational purposes.
"Corn is just a nice crop to grow. It works well with cotton and the country comes up better afterwards," Mr Derrick said.
"A late September plant works in well with our overall program. Most of the watering is done before the cotton needs it."
The corn was sown with a MaxEmerge planter at a rate of 70,000 seeds per hectare into one metre row spacings.
Ten tonnes per hectare of manure was applied in the lead-up to planting, and is put on the paddocks every second year as part of the overall soil health program.
The corn crop also received 100 kilograms per hectare of nitrogen pre-plant and an additional 50 kilograms per hectare of nitrogen applied as a liquid during the irrigations.
Just four irrigations were required to reach the yield, with the seasonal conditions generally favourable after the initial setback from the hail.
Harvest occurred in early March and both hybrids produced good sized grain with high grain weights of between 79 and 80 kilograms per hectolitre.
Mr Derrick said they were later to harvest than anticipated because of weather conditions at the time; however the corn stood well and was able to be stripped prior to the cotton picking.
He said there was not a lot of difference in yield between 31G66 and 32P55 with both performing well.
