HYC Spring Wheat “Reset” Trial locations
Aims

To assess the value of pre and post GS30 defoliation in winter and spring germplasm grown in HRZ regions of different season lengths using 17th April sowing date.

Key messages

• All defoliation treatments reduced grain yield relative to the “ungrazed” crop except the light graze treatment in Trojan.
• Those defoliation treatments that removed larger amounts of dry matter at stem elongation (GS30-32) invariably reduced grain yield more.
• The concept of “resetting” Trojan at GS32 was unsuccessful in maintaining or increasing yield.
• In Trojan “light grazing” (as opposed to hard grazing) did not reduce grain yield and was the only treatment that showed canopy compensation by flowering (GS61) when assessed by canopy reflectance (NDVI).
• With Trojan “light grazing” at GS30 which removed only 240kg/ha on July 7 increased margins by the value of the grazing $60/ha plus a small increase in grain output (not significant) of $53/ha.
