Production Technologies

  • Ecoregional agrotechniques to reduce costs and maximize production.
  • Protocols for the massive production and rapid multiplication of quality planting materials.
  • Productive and profitable cropping systems and integrated farming system (IFS) models.
  • Organic production packages for crops and cropping systems.
  • Integrated nutrient management (INM) and low input technologies.
  • Nutrient Use Efficient (NUE) genotypes of cassava.
  • Sustainable soil fertility management for continuous cassava cultivation.
  • Fertilizer best management practices (FBMP) by site-specific nutrient management (SSNM), customized fertilizers, and micronutrient formulations.
  • Precision nutrient and water management and water-saving techniques.

Site-Specific Nutrient Management

  • FBMP for different agro-eco-zones using 4R nutrient stewardship.

  • Tailor-made nutrient management for individual farms with customized plant nutrient and micronutrient formulations.
  • Technology for the preparation of customized plant nutrient formulations and micronutrient formulations.

 

Plant Health Management

Pest Management

  • Integrated pest management (IPM) for sweet potato weevil.
  • IPM for mealybug, whitefly, scale insects, mites, spiraling whitefly and storage pests.

  • Bioactive molecules from cassava crop residues.

      

     

Disease Management

  • Integrated disease management (IDM) for cassava tuber rot, elephant foot yam collar rot, etc.
  • Organic management of collar rot of elephant foot yam and leaf blight of taro.

  • Diagnostic tools for 10 viruses:

    • Indian cassava mosaic virus
    • Sri Lankan cassava mosaic virus
    • Sweet potato feathery mottle virus
    • Sweet potato leaf curl virus
    • Dasheen mosaic virus (Elephant foot yam & taro)
    • Taro bacilliform virus
    • Yam mild mosaic virus
    • Yam mosaic virus
    • Yam chlorotic necrosis virus

    Production of planting material free of 4 viruses:

    • Cassava mosaic virus
    • Sweet potato feathery mottle virus
    • Dasheen mosaic virus
    • Yam mild mosaic virus

    LAMP technique to diagnose 5 pathogens:

    • Dasheen mosaic virus
    • Sri Lankan cassava mosaic virus
    • Sclerotium rolfsii
    • Phytophthora colocasiae
    • Biocontrol agents: Two Trichoderma asperellum isolates (CTCRI-Tr9 and CTCRI-Tr15) were developed for elephant foot yam and greater yam. Additionally, four Trichoderma asperellum isolates were found effective against major fungal pathogens of tropical tuber crops, including Sclerotium rolfsii, Phytophthora colocasiae, Colletotrichum gloeosporioides, and Fusarium spp. Potential endophytes for taro leaf blight and greater yam anthracnose with growth-promoting characteristics were also identified.
    • A cassava tuber-based medium was standardized for the multiplication of Trichoderma isolates. The procedure ensures a population of >1020 cfu g-1 substrate across all isolates.
