In Summary

  • We unveil from our universities technologies to help you sort farm produce like potatoes, thresh grains, buy animal feeds, till land and take your harvest to the market.
  • The Ultra Power Machine consumes up to two litres of fuel per acre when ploughing or weeding, while for transportation of farm produce, it all depends on the distance to be covered and the weight of the produce.
  • Egerton University has sought to make work easier by developing a portable sorghum thresher that threshes, polishes and winnows the grain at once.
  • Jackson Oyugi is Nairobi biotechnology student, is using the troublesome water hyacinth to make livestock feeds and manure.

Bread made from sorghum flour

At the Jomo Kenyatta University of Agriculture and Technology (JKUAT) in Juja, on the outskirts of Nairobi, there is a small room reserved for baking loaves and cakes.

The bakery, where the loaves made from a sweet sorghum variety and wheat, is the brain child of Prof Willis Owino, a researcher and the manager JKUAT Food Technology Centre.

Prof Owino says the aim of the project, began in 2010, was to establish more uses of sorghum to enhance consumption.

To arrive with the best, the scientist tested over 40 sorghum varieties before settling on the white sorghum from Brazil.

According to him, sorghum is a healthy food as research shows it prevents the growth of cancer cells, diabetes and helps in managing cholesterol in the body.

“The bread incorporates 15 per cent sorghum, which cuts use of wheat. The aim is not to replace wheat but to reduce usage. Sorghum on its own cannot make good bread.”

Even though beer industry has created market for sorghum, many farmers are still left out because brewers’ take about 16,000 metric tonnes annually as compared to 170,000 metric tonnes produced.

“As we encourage farmers to grow sorghum, we must ask ourselves where they will find the market for their produce. Besides being a food security crop, sorghum can be used in manufacturing livestock feeds and ethanol,” Prof Owino points out.

The bakery produces 150 to 250 loaves daily, which they sell at Sh42. The sorghum is mainly sourced from university’s farm and from one contracted farmer in Maseno.

Machine tills, plants, weeds, harvests and transports produce

Any farmer will confess that tilling, planting, weeding crops and harvesting are labourious exercises.

But that should no longer be the case as the Nakuru-based Kenya Industrial Training Institute (KITI) has come up with the Ultra Power Machine that does all the tasks.

“We built the machine to ease farmers’ burden from planting to harvesting,” says Brian Busienei, a lead technician in the project and a former student of the institution.

All a farmer needs to do to use the diesel-driven machine is to affix various implements on it.

The machine consumes up to two litres of fuel per acre when ploughing or weeding, while for transportation of farm produce, it all depends on the distance to be covered and the weight of the produce.

“The machine has three gear levers and the user’s task when ploughing is to control it using the handle bars, a task which is much simpler than it may look,” says Busienei.

To use the machine for transport, the farmer simply dislodges the plough from the implement, then attaches a trailer which preferably should be bought alongside the machine, for compatibility, then drives as one would, a rickshaw or motorcycle.

Machine threshes, winnows grains

Sorghum threshing is mainly done manually across the country by beating the heads with sticks on bare ground, on spreads or with panicles contained in bags.

Manual threshing is a slow process with an output of about 15-40kg/day per person and results in losses due to spillage, incomplete removal of grains from heads, damage to grains and contamination with sand/soil and stones.

Egerton University, however, has sought to make work easier by developing a portable sorghum thresher that threshes, polishes and winnows the grain at once.

Once the dry sorghum heads are fed into the machine, the grain is produced clean, ready for the market. Thus, it needs no further processing.

While developing the machine, a team of engineers led by Dr Njue Musa worked with farmers in Meru, Thraka Nthi, Kitui and Machakos counties.

The machine, which also threshes green grams, has a capacity of 300 to 400kg of threshed sorghum per hour which is equivalent to work done by 10 people in a day.

The machine has transformed sorghum threshing, which was traditionally seen as an activity for women. With the introduction of the machine, men and the youth have joined the women.

The machine comes equipped with a simple clutch for ease of starting. Women and the youth can easily crank the engine using the clutch mechanism.

The gadget wheels are slightly off set from the centre of gravity and therefore it’s easy to lift and move the machine around, the wheelbarrow way.

Use of acacia makes meat processing easy in the drylands

Cattle keepers in dryland areas now have an innovative technology for meat processing developed at the Egerton University.

The technology involves the utilisation of beef and Gum Arabic (Acacia senegal var kerensis), readily available in the drylands.

According to Prof Symon Mahungu and Mr Johnson Mwove, the innovation harnesses the water-binding capacity of Gum Arabic, a natural product that is approved by the Codex Alimentarius and the World Health Organisation for use in foods.

The end result is a juicy meat product with high sensory attributes.
