आम में फूल-फल झड़ने की गंभीर समस्या का कारण और प्रबंधन | MANGO Fruit Dropping & Their Management

Summary

The video script discusses the common issue of flower and fruit drop in mango orchards, affecting farmers' yields. It explores the primary reasons behind this phenomenon, such as insufficient pollination, imbalanced nutrients, and adverse weather conditions. The script also offers practical solutions to mitigate this problem, including proper irrigation, balanced fertilization, and the use of growth regulators like Auxin and Citric Acid to strengthen the fruit attachment.

Takeaways

• 🌼 Flower and fruit drop in mango orchards is a common and serious issue for farmers.
• 🌸 The drop can be due to multiple factors including lack of pollination, hormone imbalance, nutrient and moisture deficiency, pest attacks, unseasonal rains, and strong winds.
• 🌻 Many flowers on a mango tree are male and will naturally fall off after pollination, which is normal.
• 🌺 Excessive use of chemicals during the flowering stage can damage flowers and reduce pollination, leading to flower drop.
• 🍃 Lack of moisture due to high temperatures and strong winds can stress the plants and cause flower and fruit drop.
• 💧 Mulching and proper irrigation can help maintain soil moisture and reduce plant stress.
• 🍯 Encouraging pollinators like bees by planting attractive flowers nearby can improve pollination rates and reduce fruit drop.
• 🌾 Nutrient deficiencies, especially of boron and calcium during flowering and potassium during fruit development, can cause flowers and fruits to fall.
• 🦟 Pests like fruit flies, midges, and mealybugs, and diseases like anthracnose and powdery mildew, can cause significant fruit drop if not controlled.
• 🌬️ Use of growth regulators like naphthalene acetic acid (NAA) can help reduce fruit drop, but they must be used in recommended amounts to avoid side effects.

Q & A

Why do flowers and fruits drop from mango trees?

Flowers and fruits may drop due to various reasons such as inadequate pollination, insufficient nutrients, water stress, imbalance of hormones, pests, and diseases.

What is the role of pollinators in mango tree flowering?

Pollinators like bees and flies are crucial for the transfer of pollen which leads to the formation of fruits after the pollination process is complete.

Why do some mango flowers appear to wither without producing fruits?

This can happen if the flowers do not receive adequate nutrients or if there is excessive use of chemicals during the flowering stage, which can damage the flowers and prevent fruit set.

What are the stages of fruit drop in mango trees?

The stages of fruit drop are commonly divided into three phases: pinhead drop, marble drop, and mature drop, each occurring at different sizes of the fruit.

What is the pinhead drop stage in mango fruit development?

Pinhead drop is the first stage of fruit drop where most of the fruits fall off the tree at the size of a pinhead, often due to inadequate care and environmental stress.

How can water stress affect mango fruit drop?

Water stress can cause the plant to feel stressed, leading to flower and fruit drop as the plant tries to conserve water by shedding parts that require more hydration.

What is the purpose of mulching in mango orchards?

Mulching helps to maintain soil moisture, regulate soil temperature, and prevent weed growth, thereby reducing water stress and supporting healthier fruit development.

How can nutrient deficiency impact mango fruit drop?

Nutrient deficiency, particularly of potassium and silicon, can weaken the fruit's ability to develop properly, making them more susceptible to dropping.

What are some common pests and diseases that can cause mango fruit drop?

Pests like mites and diseases such as powdery mildew can damage the fruit and flowers, leading to premature drop if not managed properly.

How can hormone imbalances affect mango fruit retention?

Hormone imbalances can disrupt the normal growth processes of the fruit, making them unable to develop properly and leading to drop.

What is the significance of using growth regulators in mango orchards?

Growth regulators, such as NAA (Naphthaleneacetic acid), can be used to strengthen the fruit's attachment to the tree and reduce the incidence of fruit drop to a considerable extent.

What are some environmental factors that can cause mango fruit drop?

Environmental factors like strong winds or irregular rainfall can physically dislodge fruits or stress the tree, leading to fruit drop.
