To maintain fruit quality, continuously remove and replace fruiting wood as it ages beyond its prime.
You’ve seen different training systems to achieve a variety of canopy architectures. Once the canopy architecture decision is made, and the orchard planted and trained, the desired canopy structure must be both maintained and renewed to optimise sustainable production for years, even decades, to come.
Removal—Identify wood that should be removed from older trees; and from younger trees:
Fruit trees and all plants grown in Australia’s tough agricultural environment are at risk of becoming stressed.
Drought, pests and diseases, poor nutrition and other harsh weather conditions can all play havoc with a plant’s productivity and production, negatively affecting your crop.
As we approach the coming season and bud break, we need to ensure that we give our tree crops the best chance to maximise yield and quality in the coming season.
Graeme Hardwick, AgNova Technologies’ area manager for South Australia, Sunraysia and Western Australia, is seeing tree crop growers switching back to residual herbicides to save time and money and avoid problems with resistance to glyphosate.
It has been well documented that effective pollination is a limiting factor in lifting yields in tree crops.
Not only does poor pollination limit fruit set but also fruit size and uniformity is compromised.
Because of the dense nature of modern orchards, natural air flow of pollen is much reduced and due to the sheer number of flowers that need to be visited by pollinators there is a significant reliance on other methods of pollination.
Three years ago, Mick and Kylie Carr purchased a persimmon orchard next to their grazing property Bunya Grove Produce near Gympie. They were looking for more land to run their cattle.
The mature orchard had 11,000 trees on 16 hectares, a packing shed and a local workforce for harvest time. It looked like a promising operation that would complement their grazing activities.
Thiosulfates (S2O3) fertilisers are clear liquid fertilisers that provide sulfur (S), nitrogen (N) as ammonium thiosulfate (ThioSul), potassium as potassium thiosulfate (KTS), calcium as calcium thiosulfate (CaTs), or magnesium as magnesium thiosulfate (MagThio).
Soil structure: Soft stable porous soil was considered very important for high yields in a high-density irrigated orchard.
