Tuber increase
Objective
To prove that the use of Polysulphate results in higher tuber yield and quality of ware potatoes compared to current grower standard practices.
Trial Details
Treatments
- The use of Polysulphate at planting, at a rate of 1,053 kg/ha, was tested as a source of magnesium, a nutrient absent of the current standard practice.
- 65 kilograms per hectare of Mg as magnesium oxide (MgO), was supplied by Polysulphate.
Treatments
- The use of Polysulphate at planting, at a rate of 1,053 kg/ha, was tested as a source of magnesium, a nutrient absent of the current standard practice.
- 65 kilograms per hectare of Mg as magnesium oxide (MgO), was supplied by Polysulphate.
Results
- The use of Polysulphate resulted in a significantly higher potato yield compared with the control (SOP) treatment.
- The larger significant differences were observed on marketable tubers (+2.2%), and especially with larger tubers (+3.3%).
- No significant effect was observed on tuber density, an indicator of industrial quality.
