Coconut (Cocos nucifera) is a versatile and widely grown tropical crop known for its high economic and nutritional value. One of the common problems faced by coconut growers is the flower drop and fruit drop, which can significantly reduce the overall yield. This article will discuss the causes of flower and fruit drop in coconut trees and the measures that can be taken to control them.

Causes of Coconut Flower and Fruit Drop:

Nutrient Deficiency: Lack of essential nutrients, particularly boron, calcium, and potassium, can lead to poor flower and fruit retention. A balanced and timely supply of essential nutrients can help to reduce the issue.

Water Stress: Inadequate water supply or irregular irrigation can result in flower and fruit drop. Adequate and consistent water supply is crucial for the proper development of flowers and fruits.

Pest and Disease: Insects like the coconut mite, mealybugs, and fruit flies can cause flower and fruit drop by damaging the inflorescence, flowers, and young fruits. Similarly, fungal and bacterial infections can lead to the same issue.

Climatic Factors: High temperatures, sudden changes in weather conditions, or strong winds can cause physical damage to flowers and fruits, leading to their drop.

Poor Pollination: Inadequate pollination due to a lack of pollinators, such as bees and wind, can result in poor fruit set and subsequent drop.

Measures to Control Coconut Flower and Fruit Drop:

Balanced Fertilization: Apply a balanced fertilizer containing essential nutrients like nitrogen, phosphorus, potassium, and micronutrients like boron, calcium, and magnesium. Conduct a soil test to determine the appropriate fertilizer rates and application timings.

Irrigation Management: Ensure regular and adequate water supply to the coconut trees, especially during critical growth stages such as flowering and fruit development. Drip irrigation systems can help maintain consistent soil moisture levels.

Pest and Disease Control: Regularly monitor the coconut trees for any signs of pests and diseases, and apply appropriate control measures. Use integrated pest management (IPM) techniques to minimize the use of chemical pesticides and promote a healthy ecosystem.

Cultivation Practices: Proper pruning, spacing, and mulching can help maintain a healthy microclimate around the coconut trees, reducing the impact of adverse weather conditions.

Encourage Pollination: Plant flowering plants nearby to attract pollinators like bees, and ensure there is adequate air movement around the trees to facilitate wind pollination.


Coconut flower drop and fruit drop control is essential for maximizing yield and maintaining the overall health of the coconut trees. By understanding the various factors that contribute to flower and fruit drop, growers can implement targeted management practices to minimize their impact and promote a healthy and productive coconut plantation.
