It is early morning and all roads are leading to Jinja
with farmers and various agricultural stakeholders going to participate in the
ongoing agricultural show and the Source of the Nile agricultural show ground.
On arrival the reporter’s first focus is on the
agricultural industrialization and scientist’s interest in fabricating
machinery to support small scale farmers in the rural areas in processing their
various crops ranging from legumes, root tubers and cereals among others.
A walk to Naro’s Agricultural Engineering and
Appropriate Technology Research Center (AEATREC) section, one is welcomed by a
seeing a number of agro processing machinery for various crops portable for
small scale farmers.
Background
AEATREC is one of the research centres of the National
Agricultural Research Organisation (Naro) administered under the National
Agricultural Research Laboratories (NaRL) in Kawanda. The engineering institute is located at
Namalere.
It is mandated to generate and disseminate agricultural
engineering technologies and innovations that enable farmers, cottage
processors and value chain actors meet the production, processing and agro
industrial market demand.
The centre also provides testing, evaluation,
standardization and certification services of agricultural machines and
equipment developed or imported by other players in the value chain.
The
agro processing machinery demonstrated to farmers at Jinja agricultural show
Agricultural Engineer Ronald Walozi who is a research
officer at AEATREC giving details of the recently produced agro processing
machinery by a team of scientists at the Institute notes that there are a
number of a machinery on display for farmers who are seeking such services.
These include among others Naro Light Weight Rice
thresher, ASI Rice Thresher, Naro- Soy Thresher, Naro hand Cranked Maize
Sheller, Naro Cas-Chip for chipping root tuber crops such as cassava among
others.
This innovations he notes came as a result of
challenges farmers face with harvesting and drying a number of farm produce
using ordinary method of cracking the produce and drying it under sunshine.
The ordinary way of processing these products is labour
intensive, uniformity of the end product cannot be attained as well attaining
good quality is a challenge.
“Usually before we develop a certain farm machinery in
our workshop at Namalere, we do it according to farmer’s needs. This require us
to go ground to interact with farmers in the various regions across the country
to establish farmers needs and demand to enable us to develop the right
machinery,” notes Engineer Walozi.
He explained how the various machinery operates
depending on the specification required in processing the different crop
produce with details as below.
NARO
CAS-CHIP
This is a food grade fresh cassava chipping machine
designed to produce high quality cassava chips for human consumption and
industrial use. The initiative started in 2015 and it is ongoing because a
number of farmers usually place their order and in one week the machine is
developed.
It is good for
enterprenual youth and women group who mainly engaged in cassava flour
processing in the rural farming communities as income earning initiative
It is capable of producing uniform chips which can be
easily dried when spread under sunshine. It takes about 1-2 days for chips to
dry ready for grinding to process pure cassava flour as opposed to ordinary
cassava processing that may build mould leading to poor quality flour.
It has capacity of processing 450-600kg of chips per
hour using one litre petrol and farmers are able to add value from pure cassava
flour including for baking confectionary products such as biscuits, cakes,
bread and cookies among others.
It components include a petrol engine, inlet to receive
peeled and fleshly washed cassava tubers, the hipping unit which picks small
chips the tuber. Others are the frame belt which allows and transmits power
from the engine
Farmers are encouraged to use it on farm and already
farmers from the Eastern and Northern Uganda have acquired them as groups and
individually making the processing work easy. It is cost effective because one
machine is sold at Shs4.5million.
Farmers are required to make 50%payments before the
experts embark on developing the machine and thereafter it is deployed to the
area of destination.
NARO-SOY
Thresher
This is a motorised thresher for threshing soybean
developed to avoid challenges faced when threshing manually leading to
scattering of seed in untidy places.
It is a recent machine with the first developed in 2020
after farmers growing soybean in Northern Uganda mainly in Acholi and Lango sub
region demanding it.
The machine has capacity of threshing whole dried
soybean plant between 100 and 120kg per hour with 1 litre diesel.
It is expected to be operated by 3 people, one person
feeding the plant into the inlet another operating the engine and the third
person collecting the dust and husks blown in an opposite direction.
What is required is a clean Tarpaulin Paper on which the machine is
placed on farm as threshing processing is done in order to obtain clean seeds.
The components include Engine belt, threshing unit,
input jute, dust/ husk jute, fan for blowing off the husks and the frame. It
costs Shs6 million per machine and the payments terms are the same with the
cassava chip.
NARO
Light Weight Rice Thresher
It is a motorised rice thresher specifically designed
for women and youth groups involved in rice production.
The output is 650-750kg per hour using 1 liter petrol
and it reduces physical grain loss during threshing from 4.5% - 0.1%
It weighs only 138-150kg compared to the heavy weights
of 1000kg making it easily to be hand pushed within the rice field. When using
it, the economic gain is 138 US dollars per hectare.
The components include the engine threshing unit, tyres
used for rolling it on farm since it is mobile
Most farmers using it are those in Doho Irrigation
scheme in Butaleja district and those growing upland rice in Acholi and Lango
sub region including West Nile.
It was deployed to farmers in 2016 and each costs Shs5
million.
ASI
Rice Thresher
This is a machine specifically designed for rice farms
of at least 20 hectares or farmers growing rice in groups on large scale.
The threshing output is 1,500-2,000 kg per hour and
since it is slightly heavy, most farmers prefer to use oxen, power tiller or
tractor to pull it on farm.
NARO
Hand Cranked maize Sheller
It is a simple hand cranked maize Sheller designed for
youth groups, those with vision impairment, those who are lame and the elderly
because it has a seat for someone to sit on as the push the maize into the
shelling unit one by one. Its output is 60-80kgof cleaned maize grain per hour.
NARO-1-Wedder
This is an animal drawn inter-row weeder designed to
weed mainly cereal and legume crops using a pair of oxen.
It can be easily used by women and youth since it is
light and it is capable of weeding 0.25 hectares per hour. It weeds crops with
spacing 30-90 cm in between.
These include crops such as upland rice, maize, beans
and soybean among others. It removes 91-93% of weeds in the garden in a single
weeding operation
NARO
FOR A-CHOP
This is a motorized forage chopper adopted to chop
fodder for livestock feeding. The chopped fodder can either be fed fresh or
preserved as silage for future feeding of animals.
The machine has two models which include Naro Fora-
Chop-1 which chops partially shreds forage into smaller pieces and the second
model is Naro Fora-Chop-G which performs both duties of chopping and grinding
grain for livestock.
It is mainly placed on wheels for improving easiness of
movement on farm
Its output is 500-600kg of fresh chopped forage for
light duty and 1,500-1,600kg of fresh chopped forage for heavy duty per hour.
The chopped fodder length varies from 25-50mm.
