Oilseed rape (canola) provides a useful break crop option in the rotation. Historically oilseed rape in New Zealand was grown for biodiesel production. However, this has changed, and currently most of the oil is sold as food grade canola oil. The current seasons work will focus on agronomic inputs (insecticides and trace elements) along with the effect of desiccations methods at harvest time.
This paddock scale evaluation will look at the use of plus and minus insecticide program to control Beet Western yellow Virus (BWYV). Using commercial equipment and having the trials on a large paddock scale allow more accurate results and a better understanding of the virus' effect on yield.
Various trace elements are applied to aid in oilseed rape growth. Evaluating what products are available and their best combinations and timings are being evaluated and subsequently their effect on final yield.
With strong winds at harvest time proving detrimental to shattering and yield loss desiccation methods and timings are being evaluated. Windrowing vs chemical desiccation followed by direct combining are being compared on a large paddock scale scenario.
