Key Conclusions
A single application, Agromaster increased the yield by 9 mt/ha when applied at 100% N rate. When applied at 80% N rate, Agromaster together with Polysulphate remarkably increased the yield by 22% – extra 11 mt/ha. The increase in marketable yield illustrates how Agromaster and Polysulphate are a reliable combination to fertilize soil grown crops.
Objective
To evaluate the impact on potato yield and distribution per classes when the crop is fertilized with Agromaster, as controlled release nitrogen-based fertilizer, and Polysulphate, as unique multi-nutrient fertilizer, compared to conventional fertilizers. Both types of nitrogen fertilizers, controlled release and conventional, were tested at 2 different rates/ha – 100% and 80% of advised N rate.
