Conclusion

Magnesium-fertiliser had no effect on yields although leaf analyses indicated levels lower than recommended (average of four trials). In one trial, sugar content increased significantly.

Manganese-fertiliser had no effect on yields although leaf analyses indicated levels lower than recommended (one trial harvested).

Boron-fertiliser had no effect on leaf content, which in all cases (in contradiction to previous results) was above the recommended level (two fields investigated).
