Key Conclusions
Yield of combining peas increased by 8% when Polysulphate fertilizer was applied at 100 kg/ha.
Objective
To investigate the effect of different rates of Polysulphate on combining peas (Pisum sativum L.) on a sandy clay loam soil.

Treatments
- This was a randomized trial of 4 replicates that had 3 different application rates for Polysulphate: 100, 150 and 200 kg/ha.
- The combining pea plot size was 1.5 m × 10 m.
- The plots were sown in April 2017 and harvest in July 2017.

Results
Of the 3 Polysulphate application rates tested, the best result was achieved when Polysulphate was applied at 100 kg/ha. This resulted in a yield increase of approximately 8% (0.35 metric tons per hectare). Based on a market price of £180/metric ton this represents an additional return of £62.28 per hectare.
