Lupin Yields Are Not What They Should Be : Viewpoint, M Ferguson, S. Trevenen

Journal of the Department of Agriculture, Western Australia, Series 4

Mike Ferguson has been in charge of the Three Springs office of the Department of Agriculture since 1977.

Based on trials he has done and others he has seen, he believes farmers can greatly increase their yield of lupins.

Nitrogen Fertilisers For Rape (Brassica Campestris And B Napus) And Wheat In Western Australia, M G. Mason

Technical Bulletins

Absolute yield increases tended to be greater for wheat than rape at 63 per cent of the nitrogen responsive sites, but percentage yield increases and rate of N for maximum yield tended to be greater for rape than for wheat. When average response curves over all trials were considered, there was little difference between the two crops in terms of percentage responsiveness and N rate for maximum yield in areas with less than 460 mm average rainfall, but in higher rainfall areas the response to N was higher.
