Nutritional Agronomy Note: Foliar nitrogen on Oilseed Rape – Get better results with Oilseed Extra
Foliar nitrogen on Oilseed Rape – Get better results with Oilseed Extra The HGCA now recommend application of foliar nitrogen to all crops of oilseed rape, following a number of years of trials over different seasons. Oilseed rape is poor at taking up soil nutrients after flowering, at a time when nitrogen is important for filling the seed and extra nitrogen provided through the foliage leads to a yield increase greater than can be achieved by additional soil applications. Oilseed Extra, a complete foliar package for bigger yield benefits The HGCA report an average yield response of 0.2 t/ha and other trials organisations report an average increase of 0.35 t/ha, from the application of nitrogen alone. Oilseed Extra has been shown to increase yields by an average 0.61 t/ha, from all trials over the last 9 seasons, almost double the increase. That’s worth about an extra £100/ha after the cost of the product and application.
- Maintains growth throughout seed fill, producing larger seed, higher yields
- Improved yield responses over straight foliar nitrogen
- Molybdenum inclusion minimises the oil reduction associated with straight foliar nitrogen application at lower application rates
- Evidence of reduced pod shatter from foliar urea in some trials
- Net benefit of over £100/ha, based on average results over last 5 seasons
- Can be tank-mixed with late fungicide or aphicide applications
