Tent-style greenhouse for multiplication of sweet potato vines and cuttings

Greenhouse Solutions for Thriving Sweet Potato Farms

The tent-style greenhouse is constructed using locally available materials and screen nets, which are cost-effective and easy to assemble. The greenhouse maintains optimal soil moisture, either manually or through drip irrigation, promoting healthy growth of the vines. The screen nets serve a dual purpose: they provide a barrier against pests and diseases, and they create a controlled environment conducive to growth. This technology ensures the production of high-quality, disease-free planting material, which is crucial for the successful cultivation of sweet potatoes. It’s a practical and beneficial tool for farmers aiming to increase their sweet potato yield.

Problem

  • Lack of Planting Material: Farmers often face a shortage of planting material, limiting the area of land they can cultivate with the crop.
  • Degeneration of Planting Material: Over time, the quality of sweet potato vines used as starter material can degrade, affecting the yield.
  • Pest and Disease Infestation: Sweet potato vines are susceptible to pests and diseases, which can severely impact the crop’s health and yield.
  • Poor Quality of Planting Material: The survival and growth of sweet potato vines upon planting can be compromised if the planting material is of poor quality or infected with pathogens.
  • High Costs and Infrastructure Challenges: The construction of traditional greenhouses can be costly and may require materials or infrastructure that are not readily available locally.

Solution

  • Planting Material: The greenhouse enables efficient multiplication of sweet potato vines and cuttings, addressing the issue of shortage and degradation of planting material.
  • Pests/Diseases: The use of screen nets in the greenhouse provides a barrier against pests and diseases, ensuring healthy growth of the vines.
  • Infrastructure/Cost: The greenhouse design is cost-effective and can be constructed using locally available materials, solving the problem of high costs and local availability issues.

Key points to design your business plan

For Farmers: 

Integrating a tent-style greenhouse in a sweet potato farm business can significantly enhance crop yield and quality by providing a controlled, pest-free environment and ensuring the availability of high-quality planting material. This cost-effective solution also promotes efficient use of resources, contributing to sustainable farming practices. 

Here are the key steps for a successful implementation of a tent-style greenhouse in your sweet potato farm:

  1. Learn About the Greenhouse: Attend workshops or seek information about the tent-style greenhouse, its benefits, and operation.

  2. Estimate Costs: Calculate the costs for constructing the greenhouse and purchasing vines. Include transportation, labor, and training costs.

  3. Choose the Location: Find a spot on your farm with good light, drainage, and wind protection for the greenhouse.

  4. Prepare the Site: Clear the chosen area and level the base.

  5. Build the Greenhouse: Assemble the frame, install the screen nets, and cover the frame with the plastic cover. You might need some help with this.

  6. Arrange the Plants: Place the sweet potato vines and cuttings inside the greenhouse, ensuring enough space for air circulation.

  7. Maintain the Greenhouse: Learn how to control soil moisture, temperature, and airflow inside the greenhouse.

  8. Evaluate and Improve: Regularly check the effectiveness of the greenhouse and make necessary improvements.

Remember, the timeline for these activities will depend on your specific situation and needs.

  1. Site Selection: Identify and secure an appropriate location for constructing the greenhouse. Ensure it has sufficient space and access to sunlight.

  2. Gather Materials: Acquire the necessary materials for construction, including screen netting, supporting posts, anchors, cables, and any optional components like drip irrigation system.

  3. Erecting Posts: Begin by setting up the supporting posts at regular intervals across the chosen area. These posts will serve as the framework for the greenhouse.

  4. Installing Cables: Connect the cables to the posts horizontally, creating a grid-like pattern to support the screen netting. This step provides structural stability.

  5. Sinking Cable Anchors: Secure the cables in place by sinking anchors into the ground. These anchors will help maintain tension and stability in the structure.

  6. Connecting Cables and Anchors: Ensure that the cables are securely connected to the anchors, creating a stable framework for the greenhouse.

  7. Stretching Screen Nets: Carefully drape the screen netting over the framework, ensuring it covers the entire structure. Secure the netting in place.

  8. Burying Edges of Screen Nets: Bury the edges of the screen netting in the soil to prevent pests and insects from entering the greenhouse.

  9. Optional: Installing Drip Irrigation System: If desired, set up a drip irrigation system connected to a water tank to maintain optimal soil moisture levels within the greenhouse.

  10. Monitor and Maintain: Regularly inspect the greenhouse for any wear and tear, and make necessary repairs. Ensure that the irrigation system (if installed) is functioning properly.

  11. Utilize for Multiplication: Once the greenhouse is set up, use it for multiplying sweet potato vines and cuttings. Place the planting material inside the greenhouse for propagation.
