 ABSTRACT

The field experiment were carried out to evaluate the soil nutritional status of coconut palms (Cocos nucifera L.) showing general yellowing in Thiruvananthapuram district of Kerala during 2016 and 2017. Coconut palms showing general yellowing was identified based on visual symptom and leaf samples were collected from the coconut palms showing general yellowing and healthy palms. Chlorophyll a, chlorophyll b and total chlorophyll content of leaves showing yellowing were analysed before and after the application of fertilisers. In present the study, palms showing general yellowing recorded a significant reduction in the chlorophyll a, chlorophyll b and total chlorophyll content when compared with healthy palms. Chlorophyll a and total chlorophyll contents of palms showing general yellowing before and after the application of nutrients were found to be significantly different each other.

Key words: Coconut palms, General yellowing, Healthy palms, Chlorophyll
