The Influence of Dolomitic Lime and Muriate of Potash Application on Fruit Mineral Content and Jelly Seed Disorder Incidence of Mango (Mangifera indica L.)

Jelly seed physiological condition is one of the factors leading to mango (Mangifera indica L) losses in Kenya and other parts of the world. It’s thought to be linked to a lack of N, K, Mg, and Ca in the fruit’s supply. Mango production in Kenya has increased as a result of rising demand for fruits as people become more conscious of their health benefits. The aim of this analysis was to see how dolomitic lime and muriate of potash (MOP) fertilisation affected mango jelly seed disorder and mineral content in the fruit tissue. In 2013 and 2014, MOP at rates of 0, 1.0, and 2.0 kg/tree/year, as well as dolomitic lime at rates of 0 and 2 kg/tree/year, were applied to ‘Tommy Atkins’ and ‘Van Dyke’ trees. A hedonic scale was used to rate the occurrence of jelly seeds in a group of ten tree ripe fruits per procedure. The content of K, Ca, and Mg in another fruit sample was determined. Dolomitic lime and MOP fertilisation had no effect on jelly seed score, but they did increase fruit K, Mg, and Ca content significantly when compared to regulation.
