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