Cavendish banana requires a lot of nutrients for its growth and development. The soil and leaf analysis results are the main basis for fertilization in FPO Plantation. The inherent level of potassium, calcium and magnesium is generally high in the area but the high levels of Mg dominates in the exchange complex of the soil affecting the availability of other nutrients particularly K and Ca. The production of high yielding bananas in FPO was limited by excess amounts of Mg both in the soil and the leaf. Although the concentration of most nutrients needed by banana are in adequate amounts, the presence of high Mg content caused a negative effect on the other nutrients as well as on the yield of the crop. The regular application of potassium and lime helped in adjusting the level of nutrients in the soil but it should be generated with caution to ensure that the recommended rate will not have a negative effect on the bunch weight.
