To determine the methods and rates of Mn placement required for maximum dry matter production of sub clover grown on very gravelly soils in West Dale district.
Mn defiiecy patches noted through the experiment al. Nil Mn were more severe
Topdressed Mn appeared the have similar symptoms to nil Mn
Drilled Mn at the low and high rate had less Mn symptoms
Mn foliar sprays had less Mn yellow patches.
Mn foliar sprays improved dry matter production by about 350 kg/ha in early- September
Mn foliar increased dry matter by 1200- 1500 kg/ha by late-September.
Topdressed Mn less effective than drilled
