Banana in South Africa: Net benefit increased up to 19% by application of KNO3

Using Qrop® KS as K-source, resulted in the greatest plant productiveness in marketable total hand weight, with increased return on investment for the grower. Increased N and K levels enhanced productiveness, which probably relates to the high demand of a banana crop for both nutrients. Application of KCl reduced total hand weight by an order of 20% compared to the bunches produced by plants fertilised with KNO3 for K, and 13% relative to bunches produced by the plants fertilised with K2SO4 for K.
