Can Earthworm Technology be a Backbone
of a green Revolution in Zimbabwe?
Yes it can!!
.
.
Introduction
 First green revolution in the world was based on high yielding varieties
and the application of chemical fertilizer.
 Food production increased many fold but the world continues to host
many hungry families.
 Access to high yielding varieties and chemical fertilizers for many
families in sub Saharan Africa remains an elusive virtue.
 Agricultural ecological imbalances due to loss of organic matter.What
goes to urban areas has become waste after use
 Soils have become less productive due to use of chemical fertilisers.
Introduction (cont.2)
The global scientific community is today searching for a technology
which should be:
 economically viable.
 sustainable" (friendly to the environment).
 socially acceptable (beneficial to the society).
Introduction (cont.1)
 Vermicomposting: The earthworm technology can facilitate the
reclamation of organic matter and nutrients from all sources of
organic waste.
 Vermiculture produces vermicast (vermicompost), earthworm
faeces, and worm tea. All these are rich in nutrients, plant
regulators such gibberellic acids, auxins and cytokinins.
 Recent work done by EMA through the University of Zimbabwe
established that Zimbabwe produces annually an average of
about one million tons of biodegradable organic waste.
 Research work done in India which compared the biofertilizer/
vermicompost with cattle dung and chemical fertilizers showed
the superiority of this biofertilizer from earthworms.

6) CF + CDC

From the results, it was noted that:
• Vermicompost yielded better than chemical
fertilizer alone.
• Cattle dung yielded less than vermicompost /
chemical fertilizer.
• Chemical fertilizer plus vermicompost yielded
better than vermicompost or chemical fertilizer
alone.

How can the green revolution be ignited?
 Most smallholders have no disposable income to buy inputs.
 A new income stream from breeding of earthworms can be
promoted for households.
 Every farm family has waste from animals, food waste, field
waste etc which if composted and inoculated with earthworms
can be converted to this rich biofertilizer vermicompost.

Some Benefits from earthworms
 Dried earthworms are rich in protein, about 72% balanced
protein , rich in lysine.
 This can be processed into a rich animal feed and reduce
imports of protein for the animal feed industry.
 If 100 000 rural households are breeding earthworms and
selling 10kg fresh worms per month, about 1000tons of
earthworms would be available for animal feed, export of
earthworm/ cocoons and sale to other uses such as
vermifiltration projects.
