Putting nitrogen fixation to work for smallholder farmers in Africa
Introduction
N2Africa’s main priority intervention area is Rhizobium inoculant
as Integrated Soil Fertility Management (ISFM) to maximize the
productivity of legume crops
N2 Africa activities implemented at four centers of EIAR (MAR,
JARC, PARC and DARC)
This year project activities were based up on the previous bridging
trials lessons and experiences
This year activities were well established at most trial sites
Data collection, analysis, interpretation is completed except Chick
pea in which harvesting is under way

Activities implemented
N2Africa experiments in 2014 cropping season:-
1. Diagnosis experiment activity
2. Demonstration activity
3. Adaptation activity
4. Researcher-managed agronomy activityThree crops (Common bean, Soybean and chick pea)
were tested for their response to inoculant and phosphorus
Putting nitrogen fixation to work for smallholder farmers in Africa
The response of grain yield, Biomass and Number of Nodules to
inoculation at Shala
The analysis of variance for grain yield showed significant
response to rhizobium/inoculant and phosphorus
The highest grain yield was obtained when both the
rhizobium/inoculant and phosphorus were applied (2538.1kg/ha)
followed by the application of phosphorus
Result Achieved from Diagnosis trial

Table1. Effects of Phosphorus and rhizobium on common bean yield and yield components
There was no significant response observed between –P+I and –P-I Indicated that further investigation about P rate should be required
With regards to biomass also the application of P is important+P+I produced higher active nodules than other treatments

Progress on Chickpea Trials
All the activities were established well
Data collection was made using:
Straight forward using hard copies (manually), and
Digital data collection methods (using tablets and SMS using cell
phones as pilot case study )
Five DAs and a research assistance received Google Nexus tablets,
which has all the necessary data collection sheets as deemed by
N2Africa project
Short Messaging service (SMS) Using farmers personal cell-phone

Progress on Chickpea Trials
Currently chickpea was harvested from most
experimental sites except Akako village which is
relatively highland area
Data for harvested crop is not yet compiled it is on the
process (threshing, cleaning and weighing)
All the socio-economic data was collected and being
analyzed

Progress on Adaptation Trials
This activity implemented at all locations as preplanned
Informal feedback of the farmers were good
Further assessment on the feedback from adaptation trials
will be done at near future—waiting for financial support

Putting nitrogen fixation to work for smallholder farmers in Africa
Agricultural experts and DAs from N2Africa villages and research staff obtained 5 days intensive training on both theoretical and practical training on how to operating the digital tablets for data collection
o Each android tablet was installed with Open Data Kit (ODK) version 7
Hands-on on digital tableted
Achievements on other evaluation and promotional Activities (DARC)
Putting nitrogen fixation to work for smallholder farmers in Africa
o 50 farmers trained how to send information using SMS with cell-phone
oThe templates for sms use were prepared both in Amharic and Oromifa languages.
oMore than 85 % of these
farmers were responded to the special stenciled questionnaires,
Currently 3 way data base deposit is available (N2Africa /WUR/ DZARC)
