LITERATURE REVIEW ON RICE DESTONER

The establishment and growth of ADPs, RBDAs, and cheap fertilisers were responsible for increase in rice production through large-scale farming and mechanisation. D and Johnson E. We hope silted dams will now be cleared and water channels reconstructed for dry season cultivation of rice to be possible again. Selbut Longtau Iron toxicity due to soils with high ferrous ion is common in inland valleys and irrigation sites throughout Nigeria Masajo et al. They have incorporated the use of rice bran as organic fertilisers in the farming system.

Until recently, many of these were unused even in dryland areas and those in use exhibited only limited productivity. Policy inconsistency is not only at the Federal level. 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. The fadama projects were well executed when the funds were available. From time immemorial, rice production at this bowl is dependent on water supplied from the Jere River. It is clear from Figure 2 that a classification of rice production systems according to the six vegetation zones of lowland forest, derived savannah, Southern Guinea Savannah, Northern Guinea Savannah, Sudan and Sahel in the tradition of Keay , will not be realistic.

Selbut Longtau all inputs subsidised. The Rice Bowl encompasses some village units comprising overhectares with a cultivated area of 37, ha which depend on the water from Alau Dam. In deep fadamas the land is flooded all the time or during the major part of the cropping season.

However, the reality is that the research, extension and farmer’s link is a very weak chain. Selbut Longtau Table 9. 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.

TECHNOLOGICAL RESEARCH: DESIGN AND CONSTRUCTION OF A RICE DESTONER Osueke, Christian Okechukwu

The estuarine mouth of the Cross River in Nigeria is also yet to be exploited for rice cultivation. The Portuguese word arroz has been incorporated as a loanword in many languages of West Africa Williamson, It matures in this flooded condition and may be harvested from a canoe as may be seen in Sokoto.

This includes the breeding and soil management units. Key political appointments are done on the basis of the zones. A dismal failure riec both formal research and extension systems to foster dissemination of technology to farmers with rapid feedback has been noted.

Vertebrate pests as rodents and birds are major problems in all the rice growing environments. The establishment and growth of ADPs, RBDAs, and cheap fertilisers were responsible for increase in rice production through large-scale farming and mechanisation.

It is a system developed entirely by the farmers.

The result of studies conducted on Nigerian rice from Abakaliki and Lafia rice fields showed that the length of rice ranges from 5. With proper management the dams will never fill to the point of causing flooding, but still it will hold sufficient quantities for planned water activities.

Excessive flooding, iron toxicity and lack of water control structures have been the bane of lowland swamp rice production in the Abakaliki area for instance.

Such an arrangement provides literarure cash to the farmer to buy inputs and meet cost of labour. However, in the s, the civilian government of President Shehu Shagari saw the importation of cheap foreign rice as panacea to food shortages.

The Institute hires its tractors at the rate of N An NGO can dfstoner it at the initial stages.

By government had realised that fertiliser had been a major drain on the foreign reserve and a phosphate blending plant was established at Kaduna. Wet uplands will also be an appropriate terminology for this system. This may ameliorate the disadvantage of high labour cost in ridge cultivation observed by Kowal et al. The farmer is better off not selling paddy rice because its price is as low as N Even when there was an official ban on rice imports, foreign rice has always been found in the urban markets because private investors were importing the commodity.

The threat to local rice production by imported cheap rice is real, but farmers are consistent in their response that local rice with good milling characteristics actually attract better prices.
