Full description
To assess the value of pre and post GS30 defoliation in winter and spring germplasm grown in HRZ or high yielding regions of different season lengths.Individual objectives specific to the trial were:
- Assess the dry matter offtake differences resulting from GS22, GS30 & GS32 defoliations and their effect on final harvest dry matter, grain yield and harvest index of spring versus winter wheat.
- Assess whether April sown spring wheat that has been “reset at GS32 (defoliated)” is higher yielding than GS30 and GS22 grazed and ungrazed crops.
- To assess whether the dry matter offtakes of longer season winter wheats at GS22 are more profitable (dry matter offtake and grain yield) than the same winter wheat defoliated at GS30.
