To determine optimum sowing dates and plant densities of Flip 94-090c, Flip 94-509c and Flip 94-508c.
Key messages
Results of this trial need to be treated with caution due to the low yields and adverse environmental conditions experienced throughout the season.
Growing season rainfall was extremely low (190mm c.f. 265mm long term average) and there was no subsoil moisture due to low summer rainfall. Only 9mm rainfall was recorded in October (a critical period for crop growth and yield determination). There was an extremely hot day October 13 (37OC) followed by a frost (Oct 16, -3.4) which resulted in almost complete flower and pod abortion. Approximately 80mm rain fell in November and December, ensuring that we achieved grain yields up to 400kg/ha.
Emergence was similar to target plant densities.
Results highlight the yield potential of the new lines Flip 94-090c and Flip 94-509c.
Low plant densities and later sowing tended to be higher yielding due to the late rainfall. This is the opposite trend of 2003 and needs further investigation.
There was a greater proportion of large seed (>8mm) of Flip 94-090c at low plant densities compared with high plant densities (25% c.f. 5%).
