Proper Fertilization Methods for Bitter Melon

Bitter melon requires a substantial amount of nutrients, especially when the plant transitions to reproductive growth. Timely fertilization and nutrient supplementation are essential for achieving abundant flowering and fruiting with high-quality results. So, what are the correct methods for fertilizing bitter melon? Let's find out.

Proper Fertilization Methods for Bitter Melon

1. Base Fertilizer

It is recommended to apply 3-5 tons of well-rotted organic fertilizer, 50 kg of calcium magnesium phosphate, and 4-6 kg of urea per acre as a base fertilizer about one month before transplanting the bitter melon. When applying the base fertilizer, ensure it is thoroughly mixed with the soil for better efficacy. Additionally, the fertilizer should be well-decomposed and fermented beforehand, and it should not come into direct contact with the roots during application.

2. Topdressing Fertilizer

1. Seedling Promotion Fertilizer

On the basis of sufficient base fertilizer, a small amount of seedling promotion fertilizer can be applied. Primarily use water-soluble fertilizers, and foliar sprays such as Green Leaf Gold, Tianzhimei, and Beilvkang can be used to promote early seedling growth.

2. Growth Fertilizer

When the bitter melon seedlings reach about 30-40 cm in height, apply 80 kg of organic fertilizer and 0-10 kg of compound fertilizer (15-15-15) per acre to promote the growth rate and quality of the seedlings.

3. Flower Promotion Fertilizer

Apply flower promotion fertilizer one week before the bitter melon starts flowering or when it is about to bloom. The fertilizer should primarily consist of phosphate, with a possible addition of boron fertilizer.

4. Fruit Strengthening Fertilizer

After the bitter melon fruit reaches 3-4 cm in length, apply fruit strengthening fertilizer, mainly consisting of phosphorus and potassium. Apply 5 kg of phosphate and 4 kg of potassium fertilizer per acre. Adequate phosphorus and potassium fertilizers promote the expansion of the bitter melon fruit.

5. Late-Stage Fertilizer

In the later stages, combine watering with the application of autumn melon fertilizer. Apply 20-25 kg of 45% compound fertilizer per acre, and simultaneously spray a mixture of 0.2% urea and 0.3% potassium dihydrogen phosphate to prevent premature aging. This practice extends the harvest period and improves the quality of the commercial melons.

In conclusion, bitter melon has a high demand for fertilizers. Proper fertilization practices not only significantly improve the utilization rate of the fertilizers but are also key to ensuring a high yield of bitter melon.

How to Fertilize Bitter Melon?

Bitter melon, also known as bitter gourd or Momordica charantia, is a nutritious vegetable commonly grown in tropical and subtropical regions. Proper fertilization is crucial for the healthy growth and productivity of bitter melon plants. This article provides detailed guidelines on how to fertilize bitter melon effectively.

Understanding Nutrient Requirements

Bitter melon plants require a balanced supply of nutrients throughout their growth cycle. The key nutrients needed include nitrogen (N), phosphorus (P), and potassium (K), along with essential micronutrients like calcium, magnesium, and iron. Understanding these requirements helps in selecting the appropriate fertilizers.

Soil Preparation

Before planting bitter melon, it is important to prepare the soil to ensure it is rich in organic matter and well-draining. Here are the steps to prepare the soil:

• Soil Testing: Conduct a soil test to determine the nutrient levels and pH of the soil. Bitter melon prefers slightly acidic to neutral soil with a pH of 6.0 to 7.0.

• Adding Compost: Incorporate well-rotted compost or organic manure into the soil to improve its fertility and structure.

• Initial Fertilization: Apply a balanced fertilizer, such as a 10-10-10 (N-P-K) ratio, to the soil before planting. This provides a good nutrient base for the young plants.

Fertilization During Growth Stages

Proper fertilization during different growth stages of bitter melon is essential for optimal growth and fruit production. Here are the recommended fertilization practices:

Vegetative Stage

During the vegetative stage, the plants focus on developing strong vines and foliage. Nitrogen is particularly important at this stage. Follow these steps:

• Fertilizer Type: Use a nitrogen-rich fertilizer, such as a 20-10-10 (N-P-K) ratio.

• Application Rate: Apply 1/2 cup of fertilizer per plant every 3 to 4 weeks.

• Method: Apply the fertilizer around the base of the plants, avoiding direct contact with the stems and leaves. Water the plants thoroughly after fertilization to help the nutrients penetrate the soil.

Flowering and Fruiting Stage

During the flowering and fruiting stage, the nutrient focus shifts to phosphorus and potassium, which support flower development and fruit set. Follow these steps:

• Fertilizer Type: Use a fertilizer with a higher phosphorus and potassium content, such as a 10-20-20 (N-P-K) ratio.

• Application Rate: Apply 1/4 cup of fertilizer per plant every 2 to 3 weeks.

• Method: Apply the fertilizer around the base of the plants, similar to the vegetative stage. Ensure that the plants are well-watered after fertilization.

Additional Tips for Fertilizing Bitter Melon

In addition to regular fertilization, consider the following tips to ensure healthy bitter melon plants:

• Mulching: Apply organic mulch around the plants to retain moisture, suppress weeds, and improve soil fertility.

• Foliar Feeding: Occasionally use foliar sprays containing micronutrients to address any deficiencies and promote healthy foliage.

• Monitoring: Regularly monitor the plants for signs of nutrient deficiencies, such as yellowing leaves or poor growth, and adjust fertilization practices accordingly.

Conclusion

Fertilizing bitter melon effectively involves understanding its nutrient requirements and providing the right nutrients at different growth stages. By preparing the soil properly, using appropriate fertilizers, and following recommended application rates, you can ensure healthy and productive bitter melon plants. With proper care and attention, your bitter melon crop will thrive and produce bountiful yields.

How Often Do You Fertilize Bitter Gourd?
