The fall of the nuts prior to maturity is an important problem in coconut cultivation. Possible factors involved include physiological disturbance in the tree, defective fertilization, carpel abortion, cultivar variations, soil moisture and drought, nutrition, diseases and pests. It is important to ask a local coconut Agronomist to visit the orchard and identify the cause of the premature drop prior to proposing a solution.
Premature button shedding is a very common problem observed on coconut. Buttons can be shed after fertilization and some nuts are shed after setting. This is not due to a single cause but may be due to combination of one or more factors like excess acidity or alkalinity, poor drainage facilities, severe and prolonged drought, genetic disorders, insufficient nutrients, improper pollination, hormone deficiency, insect pests or poor management practices. Consult expert from Horticulture, find out actual cause and then follow proper remedial measures.
