SAH cassava Semi Autotrophic Hydroponics for Cassava Multiplication

A rapid quality seed delivery technology for cassava

Semi Autotrophic Hydroponics (SAH) for Cassava Multiplication is an innovative technology tailored for cassava propagation. Unlike traditional methods, SAH utilizes controlled environments with modified soil, plant roots, and limited water in trays. This fosters robust root growth while mitigating moisture-related diseases. The technique is cost-effective and adaptable, particularly for dispersed farming communities. SAH yields high-quality, disease-resistant cassava plantlets at a fraction of the production costs of tissue culture. This advancement not only expedites access to new cassava varieties but also bolsters overall productivity and resilience in cassava farming practices.

Problem

  • Slow Propagation of Improved Varieties: Traditional methods are time-consuming and limit the distribution of new cassava varieties.
  • Contamination Risks: Conventional propagation methods are prone to pests and diseases, hindering the quality of cassava planting material. SAH provides a controlled environment to mitigate these risks.
  • Limited Multiplication Ratios: Methods like seed and tissue culture have low multiplication ratios, resulting in few new planting materials from one seed.
  • Pathogen Susceptibility: Planting materials obtained from stem cuttings may be more susceptible to pests and diseases when planted in open fields.
  • Inefficiency in Scaling Production: Traditional methods may not be conducive to efficiently producing large quantities of cassava planting materials for wide-scale distribution.

Solution

  • Fast Propagation of Improved Varieties: SAH enables rapid access to new and improved cassava varieties by providing a controlled environment that accelerates the multiplication process.
  • Contamination Prevention: SAH minimizes the risk of contamination with pests and diseases by creating a controlled environment that promotes healthy root growth and discourages disease-causing factors.
  • Increased Multiplication Ratios: SAH significantly improves multiplication ratios compared to methods like seed and tissue culture, resulting in a higher number of new planting materials from one source.
  • Enhanced Disease Resistance: Planting materials produced through SAH are more resilient and less susceptible to pests and diseases when planted in open fields, compared to those obtained from stem cuttings.
  • Efficient Scaling of Production: SAH provides a cost-effective and adaptable solution for dispersed farming communities, making it feasible to efficiently produce large quantities of cassava planting materials for widespread distribution. This addresses the inefficiency in traditional production methods.

Key points to design your business plan

Seed Multiplier 

Production of this technology provides a cost-effective solution that tackles slow propagation and contamination issues in Cassava improved varieties. It can easily be used by scattered farming communities.

In order to multiply efficiently the plantlet:

  • Construct growth chamber or screen house and procure shelves and growth media for propagation, 

  • Obtain seeds or in-vitro mother plants from improved cassava varieties that are free of pathogens, and 

  • Organize marketing and delivery of SAH plantlets through existing suppliers in the cassava seed system. 

You need to fulfill national phytosanitary regulations and a license for setting up SAH activities..

Your potential customers are : wholesale distributors of seed to retailers, and to development projects, government agencies, and NGOs. 

Building strong partnerships with wholesale distributor networks is key to the success of your business.

 

For Users

Tissue Culture Production: Begin by producing tissue-cultured (in vitro) cassava plantlets under semi-hydroponic and semi-controlled environmental conditions.

Mother Plant Preparation: Cut the tissue-cultured plantlets into mother plants. These mother plants will serve as the source for further propagation.

 Tray Setup: Place the mother plants into trays with modified soil. Ensure that the trays are adequately spaced to allow for proper growth.

Growth Chamber Placement: Transfer the trays with the mother plants into a growth chamber. This chamber provides a controlled environment that is conducive for root development.

Recutting: After 2-3 weeks, recut the mother plants to obtain two plantlets from one. This step effectively multiplies the number of available plantlets.

Root Development: Return the recut plantlets to the growth chamber for an additional 6-8 weeks. During this period, the plantlets will develop well-formed roots.

Transportation: Trays can be transported in perforated cardboard boxes for up to 48 hours. This allows for convenient transportation to the planting site.

Planting: Plant the developed cassava plantlets directly in open fields or in screen houses for further breeding or production.
