Farmers have their own way of judging what production technology
to adopt and what not to; this assumption comes after Got Kowiti Livelihood
group decided to stretch their Red Creole bulb onion (Allium cepa) production
to an acre after more than 2 consecutive demo trials in smaller scales.
On 30th October 2013, in the presence of the head
of Kobama division Ministry of Agriculture, Mr. John Omotto, we were able to
join the group in the new stretch as knowledge facilitators. The farmers here have
remained optimistic even with the unstable rain patterns having experienced
similar cases at the previous demo sites.
TIPS
Statistics have indicated so far that bulb onions respond
well to fertilizer application because rooting structure is shallow and limited
to the depth of 5 cm. It is important to add organic matter too to improve soil
moisture retention ability and soil structure. An equivalent of 56 Kg/Ha of
Nitrogen should be applied as farmyard manure.
What one needs to put into consideration is that nitrogen
and potassium is not recommended at flowering because flowers become
unattractive to bees; that are so important during pollination.
When the onions experience a copper e\deficiency, they
become thin, poorly colored and have a poor bulb storage life. This can be
improved by application of 22 Kg/Ha of Cuso4. Manganese deficiency
is also common in onions; it is seen as leaf chlorosis. This is often observed in
alkaline soils thus adding an acid based fertilizer e.g. ammonium sulphate. It is recommended that one should maintain the
soil PH at 6.0 – 6.5 through regular soil testing to prevent the incidence of
manganese deficiency.
Market
The current average price in major towns per the 15Kg net is
KES 750, which means a kilo is able to fetch a farmer KES 50. With a harvest of
17,000 kilograms per hectare, the farmer will be able to raise a cool KES 850,
000 after the five months.
Remember that onion is one of the vegetables that can performer very well in a fertile soil with less use agrochemicals. Try this and be rich after 5 months.
