Location

Kahang, Johor, Malaysia.

Objective

To demonstrate the effectiveness of Granular Polysulphate to improve the growth and yield of watermelon grown on a sandy loam soil in Malaysia.

Treatments

This demonstration consisted of two treatments. One was farmers’ practice of 400 kg/ha of NPK compound fertilizer (12-12-17 +2MgO) and 200 kg/ha of 16-16-16 +2MgO. The other treatment was farmers’ practice + 100 kg/ha of granular Polysulphate. In both treatments fertilizers were applied as top dressing on the planting bed before transplanting.

Results

  • During early growth, minimum mortality and root fungus infection was observed in the Polysulphate treatment. Young shoots appeared stronger and greener.
  • Vegetative growth in the Polysulphate treatment showed bigger shoots and leaves, covering all the soil.
  • Yield increased by 33% in the Polysulphate plot compared to the farmer's usual fertilizer treatment plot. Bigger fruits were also observed with Polysulphate application.
