Delaying sowing by 2-3 weeks after the season break resulted in a yield reduction of approximately 40% at Minnipa and Hart and 10% at Turretfield... Kaspa generally had higher yields at sites where powdery mildew reduced yields of susceptible varieties and Parafield had higher yields at some low rainfall and frost affected sites... Nipper is resistant to ascochyta blight and botrytis grey mould (BGM). It has round seed similar in shape and size to Northfield and is best suited to medium to high rainfall zones where ascochyta blight and BGM are most prevalent...

The primary aim of this paper is to provide farmers with a tool which can be used to determine the point at which a lower yielding variety which is more resistant to sprouting (MS-S) becomes a better option than a higher yielding but sprouting susceptible variety (S)... In order to formulate the values to be used for discounts, an average price was obtained for AH grain, using monthly figures over the previous 5 years... Table 5 shows that in a situation where the varieties are both the same, either AH vs AH or APW vs APW, the yield penalty needs to be quiet small for it to make economic sense to grow a variety with lower yield when sprouting is only a 1 in 6 occurrence...
