SR = Short Rains from October - February;
LR = Long Rains from March -
August
N-bal = Partial N-balance (IN1 + IN2 - OUT1 - OUT2)
FFS-score = 20 points divided over treatments on preference of technology
VCR
= (GrossValue Treatment - GrossValue Control)/(VariableCosts Treatment -
VariableCost Control);
FYM
= Farm yard manure.
This has resulted in the development and testing of technologies such as green
manuring technologies (tithonia, green manure legumes etc.); manure and composting;
Rhizobium inoculation of beans; tillage practices in Napier production; livestock
feeding; and organic and inorganic combinations for crop production. Examples of
experiments and its results in one of the FFS in Kenya are presented in Table 3.
The project has trained FFS facilitators drawn from national agricultural extension
systems and the private sector for running FFS and up-scaling the same. A number
of workshops and meetings have also been organized for policymakers to discuss
FFS and Integrated Nutrient Management in the target countries of Kenya, Uganda
and Ethiopia. To further enhance sharing of the project outputs, a website was created
to give opportunities for persons and organizations working in the area of soil
fertility management and Farmer Field Schools access to various project reports and
outputs (www.inmasp.nl). Jointly with FAO a FFS manual for implementing INM
with FFS in East Africa is published.
