Total N kgs/ha Including Splits kgs/ha
Conclusions
➢ Our results reflect what we learnt in the first year of this trial ➢ Optimum remains to be 250kg/ha applied in 4 splits ➢ MOP appears to aid uptake of N in high N application scenarios ➢ This is seen as increased yield without diluting grain protein
