With the Scheme came job opportunities as parboiling rice, fabrication of parboiling drums, milling jobs etc. Selbut Longtau percent of the national rice production area and 10 to 14 percent of the national rice output. The potential for irrigated rice production can be increased considerably if water lifting through small pumps can be introduced. Sand stones are formed from sediments, and ranges from 2. The midge Orseolia oryzivora is more common in the south. He goes back to the farm only at harvest time.

There is a huge market for local rice which is the preference of consumers and traders alike. The cassava debate is even more disturbing because its root cause can be traced to the success story of the IFAD funded cassava improvement and multiplication programme. However, it is clear that for Lagos, there is actually a decline in rice cultivation. This present design of rice de-stoner take advantage of its bio- engineering properties which includes gravimetric properties, aerodynamic properties, frictional properties, rheological properties, mechanical and physical properties to separate rice from its impurities which is a more efficient method of de-stoning. It collects information on new technologies from research institutes, packages them and hand them over to the ADPs for dissemination to farmers. This is not true, but that belief can reduce the potentials of a rice field given the good moisture regimes of the area.

However, it is intended to boost vegetable production and not rice. Large- scale farmers were unable to control the use of inputs whose costs were subsidised, leading to excess release of chemicals into the environment due to misuse.

A preference of one type over the other will determine the focus or direction for both formal research and extension. The failure of these schemes is easy to account for. In Tarok land of Plateau state, central Nigeria, this impermeable layer has a vernacular term alam. The quality of local rice is one of the factors that led the elite to put pressure on government to import the commodity.


The farmers will say “inorganic fertilisers will make our rice to grow only leaves, and so we have no need of them on our fadamas”. Its bulk density is 0.


Over km of River Niger flows through Kebbi. According to the judgement of the observing farmer, the rice farmer may be approached for liyerature. The growing season in the flatlands of the Sudan-Sahel is only 90 days Dugje, This includes the breeding and soil management units. Rice imports and local production in Nigeria, However, the NARS consider such varieties as unprofitable given their low yields.

The grains are well filled given the excellent management system. The import substitution policy of the military administration of Generals Mohammed Murtala and Olusegun Obasanjo in to was to make sure that Nigeria was self-sufficient in wheat, maize and rice. At the farmgate today, a farmer sells 1 kg of milled rice for about N With the Scheme came job opportunities as parboiling rice, fabrication of parboiling drums, milling jobs etc.

The plant has the ability not to be submerged. This ingenuity on the part of farmers was again reported to NARS, and up till today no single research has been conducted on this phenomenon of the use of muriate of potash as a rice herbicide.

Yields have been consistently low on farmers’ fields in the face of ever increasing cost of inputs as fertilisers, tractorisation, herbicides, insecticides, manual labour and transportation of produce. There seems to be no solution in sight concerning the neglect rice production has suffered since the days of Structural Adjustments SAP of This system is plagued by the problem of low yield because of the use of unimproved varieties of the traditional rice Oryza glaberrima.


The variety locally called Jango is preferred here. This point illustrates that the workings of governments are not easy to fathom and may be based of information which may not be necessarily scientific and rational. This sensitivity to economic realities is especially true of large-scale farmers. In the literatuge place NSS lacks the logistic support to rebiew rigorous field standards as site selection, removal of volunteer crops, timely and effective weeding and so on.

Hence, many have resorted to consuming imported rice. Upland Bauchi Hydromorphic, Rainfed Potentials in the northern part of the state for irrigated rice Upland remains unexploited. The shortage of expertise to operate very sophisticated machinery as combine harvesters, huge ploughs and harrows, boom sprayers, seeding machines, fertiliser spreaders and so on, greatly contributed to the closing down of large-scale farms.

NCRI collects such to test for their suitability in Nigeria and possible release. Using water to control rats is a sound cultural practice.

The ideal situation is for NCRI for example, to be fully equipped to attend to rice and sugarcane problems only, and in any part of the country. Zamfara No infrastructural support to resident farmers.
