PRODUCTION OF ONIONS ON SANDY SOILS USING CEREAL NURSE CROPS |
| Author: | T.K. Twigden |
| Abstract:
Historically, onions grown on sandy soils, low in organic matter in South Australia have been subject to damage by sandblasting in Spring. Early seedling deaths have resulted thus producing unpredictable plant populations. The introduction of cereal nurse crops in the past seven years has enabled the eastalishment of more predictable populations of onions. More even bulb size and matching of density to market requirements have thus been made possible. Additional benefits include reduced irrigation requirements, less damage from post-emergent herbicides, minimised nutrient leaching, more even maturity, and reduced grower stress levels during the crop establishment phase. | |
