A cup of cocoa a day may keep the doctor away

CRIN has developed:

Hybrids that produce in 5 years with an an annual average yield
of about 2,000 nuts/tree/year of marketable sizes (12-15g)
Vegetative propagated materials that starts fruiting in about
three years;
A natural insecticide, spindor dust (a.i. spinosard (0.125%))
for protection of kolanuts in storage against kola weevil,
Bolanogastis kolae
Kola pod husks with organic materials such as poultry droppings
as organic fertilizers.

CRIN has developed:

64 varieties of coffea Arabica in Germplasm for genetic improvement
A socioeconomically acceptable method of rehabilitating
old coffee plantations with overgrown trees through
coppicing at 30cm above ground level to rejuvinate old plants
Management techniques of plant geometry by de-capping to a
height of 1.5m to facilitate harvesting
The use of half node stem cutting for propagating robusta coffee
Open rooted method of propagating and transporting stem cuttings of
robusta coffee
A method of termite control on coffee by spraying the waste water from
cassava processed for '' fufu'' production
Organic manure made from chromolaena odoratum (siam weed), cow dung,
grasses and maize stovers as effective inorganic fertilizers

CRIN has these:

Germplasm of 24 highland clonal tea genotypes introduced from Kenya
Germplasm of high yielding lowland tea varieties from China
A new rapid method for determining the field pluck (harvest) quality for tea
DNA molecular characterization of 20 clones, which could assist in parental
selection for subsequent hybridization
Recommendation on appropriate fertilizer application on test

CRIN has developed:

Seeds and seedlings of 25 superior genotypes, high
yielding (10=13kg/tree/year) with superior flavour
Appropriate site/soil selection packages for cashew
cultivation and effective fertilizer regime to correct mineral
deficiencies
Effective seed propagation methods, establishment, spacing,
pruning and inter-cropping
Clonal and vegetatively propagated cashew as planting
materials through marcotting
Suitable fungicide and insecticide mixtures to control
incidene of ravaging inflorescence blight diseases
