Effect of boron on canola  on  soils  of the south coast region of WA locations
Aims

To determine the rates of boron required for maximum grain yield of canola  grown on  soils of the south coast area.

Canola was thought to have a high B requirement so a range of sites were selected to determine any response incanola to B applications.

Key messages
  • Summary 1994 experiment

  • Soil extractable B was 0.7 mg/kg.

  • B application (Borax) decrease seedling emergence (57 to 42)

  • B concentration in dry matter (DM) 22 mg/kg B nil; 27 mg B kg for highest B application

  • B fertiliser decreased the  September Dry matter (DM) by 0.37 t/ha; decreased Seed yield by 0.17 t/ha  &  had no effect 0n N % in DM  and  N in the seed.

  • B had decreased %oil (0.29 % decrease in Oil%) & decreased oil yield by 90 kg/ha .

    Care needs to be taken on use of borax fertilizer as toxicity was induced in canola and lupin; with 0.34 to 1 kg B ha−1(3-10 kg borax ha−1) at sowing depressing seed yield, mostly by decreasing plant density. Rather than making general recommendation for B fertilizer application based on 0.01M CaCl2 soil extractable B, soil and plant analysis should be used to diagnose B deficiency and B fertilizer use limited to calcium borate or foliar borax rather than soil-applied borax on low B sands.
  • Boron not required for the site with 0.40 soil extractable B.
