Excessive shedding of buttons in coconut is a problem often faced by farmers. Coconut is a monoecious palm producing both male and female flowers on the same inflorescence. The central axis of the inflorescence has up to 40 lateral brances, each of which bears 200-300 male flowers and one or a few female flowers. The number of male flowers on the inflorescence is enormous ranging between 8000 and 10000. Though the number of female flowers on an inflorescence usually ranges between 30 and 40, palms that produce inflorescences with female flowers in considerable larger numbers are common. The number of nuts that reach full maturity is usually only 5-10 per inflorescence. Since far more female flowers are produced than the palm can sustain to the stage of maturity, considerable number of female flowers sheds in button stage during the first two months. Shedding up to 60 percent of the buttons normally occurs. In palms with excessive female flower production, button shedding would be still higher. A few immature nuts also may fall off later.

Shedding of buttons in unusually high numbers is a matter deserving attention and adoption of remedial measures. Excessive shedding of buttons in coconut may be due to any one or more of the reasons such as insufficient pollination due to low population of pollinating insects, unfavorable conditions like drought and water logging, nutritional problems, pest attack and incidence of diseases. Tackling the problem of undue button shedding is sure to improve nut yield in coconut. Appropriate remedial measures are to be undertaken for identifying the causes for excessive button shedding.
