narrow row spacing

Catalogue: Ground Cover
Growers in the Riverine Plains region of north-east Victoria and southern New South Wales are using local research to tackle local challenges... Nick Poole never wanted to be stuck in a lab, so it is no surprise he has spent most of his 30-year research career in paddocks across the UK, New Zealand and Australia, working with growers to solve challenges as diverse as chemical resistance, water use efficiency and nitrogen strategies... "Some growers use wider row spacing to get through long-term stubble burdens, but this trial identified a yield decline from wide row spacing," Adam says...

A trial in Western Australia's northern grainbelt has confirmed that narrow row spacing can boost wheat yields while acting as an important non-herbicide tactic to out-compete weeds... "Results from this trial and previous research suggests that farmers will benefit from using the narrowest row spacing practical, and I believe this should be a consideration if they are thinking about upgrading machinery," researcher Peter Newman said... Mr Newman, a communications leader with the Australian Herbicide Resistance Initiative (AHRI) and based at Planfarm, coordinated the trial funded by the Grains Research and Development Corporation (GRDC) and supported by the Department of Agriculture and Food (DAFWA)...

While a cereal crop can shade broadleaf weeds, the weeds will still move their leaves to get the maximum benefit from any sunlight reaching them through the crop canopy... Crops sown in an east-west orientation are less successful in suppressing the growth of broadleaf weeds compared with grass weeds... Crop orientation will have a greater impact on farms in southern Australia, compared to northern Australia...

The impact of row direction has been examined in combination with row spacing and population for the first time to maximise yields in the prime sorghum-growing region of NSW's Liverpool Plains... "Under these essentially non-water limited conditions there were no significant differences between row direction or row spacing at both trial locations and the only population response was at the Somerton site at 37,000 plants per hectare, resulting in a lower grain yield," Ms Serafin said... "Although plant population treatments differed markedly in plant, tiller and head density it appears that the crop was able to compensate through increased grain numbers as there was no difference in the grain size between any of the treatments at the Premer site," Ms Serafin said...

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...

Regardless of the tools used, maximum yield potential won't be achieved unless the basic agronomic practices, including summer weed control, sowing time, variety and nutrition are prioritised... Permanent traffic lanes and matched sowing-harvesting runs in a CTF system are ideal for replicated research trials where repeatability and accuracy are able to be maintained in large scale plots using 2cm RTK guidance... The repeatability and accuracy of CTF systems means canopy management principles can be assessed in commercial no-till situations using large scale, replicated plots...
