Callum keeps the wheels turning on seeding innovation.. Grower Callum Wesley, of Southern Cross, is developing and trialling a new seeding system for lower-rainfall areas - called the Wesley Wheel - that harvests moisture in inter-row furrows... At Southern Cross, Callum says it was a challenging season, where daily rain events in June, July and August did not exceed 5.4mm - reducing water-harvesting potential...

The potential to dramatically increase chickpea yields by up to one tonne per hectare through a simple change in row spacing is set to deliver increased profit margins for Dalby grain grower Glenn Milne... "We were growing chickpeas on 30 inch or roughly 75cm row spacings but because the trial showed there was a significantly higher yield on offer we have already halved our row spacings to 15" (37cm) - all we did was double planted them with our 30" planter to get our 15" row spacing... " Mr Milne owns and leases a total of 600 hectares of highly fertile black soil country on the Jimbour Plain just north of Dalby, growing dryland sorghum, chickpeas, faba beans, mung beans, barley and wheat, as well as some irrigated cotton and corn...

Although there were no differences in nitrogen fixation between the three varieties on trial, the narrow row spacings also delivered significantly better results for nitrogen derived from the atmosphere and total amount of N fixed, particularly at the Dalby site... Previous research has shown that as a legume crop's demand for N increases, so does the N fixation by that crop, but Mr McKenzie said the row spacing effect on N fixation could not simply be explained by higher plant N demand as all crops were at the same plant population density of 30 plants/m2... "In the narrow rows we observed that total N on a hectare basis was higher due to higher plant biomass, but also the proportion of the N derived from the atmosphere was higher in the narrow rows," he said...
