Summary

This interview takes place in Suka Dame village, where the team discusses the challenges faced by local cabbage farmers in North Sumatra. Mama Ester, a local farmer, shares insights on pest problems, particularly the butterfly larvae, and methods for pest control using specific pesticides. She also talks about the importance of soil pH, proper fertilization, and planting techniques to improve yields. Additionally, Mama Ester suggests that better export opportunities for cabbage could boost the region's agricultural competitiveness. The conversation provides valuable insights into the practicalities of cabbage farming and the need for support from local authorities.

Takeaways

• 😀 The interview is conducted in Desa Suka Dame with Mama Ester to discuss challenges in cultivating and marketing cabbage in North Sumatra.
• 🌱 The main pest issue affecting cabbage cultivation is the butterfly, particularly the caterpillar that damages the leaves.
• 🌿 Pest control involves spraying insecticides, typically every 2-3 days, to manage pests like the butterfly caterpillar effectively.
• 🌾 For weed management, Mama Ester uses Boral and Agil herbicides, with specific dosages: 2 tablespoons of Boral and 10 ml of Agil per treatment.
• 💧 The cabbage seeds are typically left in the nursery for 21 days if it rains, and up to a month if there is no rain, before being transplanted.
• 🌾 Land preparation for planting involves soaking, plowing, and leveling the soil before marking the planting rows.
• 🌱 Cabbages are planted with a spacing of 50 cm between rows and 30 cm between plants for optimal growth.
• 🌻 The cabbage heads are ready to harvest when they become smooth, round, and firm, typically 3.5 to 4 months after transplanting.
• ⚠️ Factors affecting the yield of cabbage include soil fertility, proper fertilization, weather conditions, and consistent pest control.
• 🍂 Low pH levels in the soil can negatively impact cabbage growth, preventing proper nutrient absorption. Lime and manure are used to improve soil pH.
• 🚜 Mama Ester mentions that the local government offers subsidies for fertilizer, but further support such as opening export opportunities for cabbage is needed to increase competitiveness in the market.

Q & A

What are the main challenges faced by cabbage farmers in the highlands of North Sumatra?

The main challenges faced by cabbage farmers include pest problems, particularly from butterflies (which cause caterpillar infestations), and issues related to the weather such as heat and drought.

How does the butterfly pest affect cabbage plants?

The butterfly lays eggs on cabbage leaves, and once the eggs hatch, the caterpillars feed on the leaves, causing damage to the plants.

What is the recommended method for controlling the butterfly pest on cabbage plants?

Farmers spray the plants with pesticides, typically twice a week, and continue spraying every two days if the caterpillars remain present to ensure they are eliminated.

How do farmers control weeds around cabbage plants?

Farmers use herbicides like Boral and Agil, applying specific doses to control the weeds without affecting the cabbage itself. Boral is used at 2 tablespoons per application, and Agil at 10 milliliters.

How long does it take for cabbage seeds to be ready for planting under different weather conditions?

Under rainy weather, cabbage seeds are ready for planting after 21 days. In dry weather, seeds may need to be kept in the nursery for up to one month before being transplanted.

What is the process of preparing the land for planting cabbage?

Farmers soak the land, remove weeds, and plow the soil before using a string to mark planting rows. They then create planting holes, with rows spaced 50 cm apart and plants 30 cm apart within each row.

How many times are the cabbage fields typically weeded before harvest?

Cabbage fields are typically weeded twice: once before transplanting and again a month later after the seedlings have grown.

When are cabbage plants ready to be harvested?

Cabbage plants are ready for harvest when they form compact, round heads with smooth leaves. The cabbage should be heavy, indicating that it is fully mature.

What are the factors that influence the yield of cabbage crops?

Factors affecting cabbage yield include soil fertility, adequate fertilization, favorable weather conditions, and regular pest control. A lack of these factors, such as low pH or insufficient watering, can reduce yields.

What can cause cabbage crops to fail, and how can these issues be prevented?

Cabbage crops may fail due to pests like butterflies, low soil pH, or poor root development. Farmers can prevent these issues by applying agricultural lime to raise soil pH and rotating pest control chemicals to avoid resistance.
