ABSTRACT
The study was conducted to examine the Effect of oil palm
processing on socio economic growth of farmers in Kogi State of Nigeria. The
objectives of the study are to: determine the factors affecting resource use
efficiency by Oil Palm Producers in the study area and determine the optimum
replacement age of oil palm. The tools of analysis used are:- simple
descriptive statistics, multiple regression analysis, optimum replacement model
and gross margin analysis. From the estimate of oil palm in the state,40,30,20
and 30 oil palm farmers were proportionally and purposively sampled from the four
(4) Agricultural Zones, A,B,C and D with their headquarters at Ayetoro-Gbede,
Anyigba, Koton-Karfe and Alloma respectively, to give a sample size of 120 oil
palm producers. The oil palm producers were interviewed with structured
questionnaire to obtain information on oil palm production. Data for optimum
replacement age were obtained from NIFOR oil palm plantation, Acharu
substation. The data collected were analysed using the tools of analysis as
specified. The t-values and F-statistics
are significant up to 5 percent level of significance. The oil palm currently
on the fields were planted over 26 years ago, most of which are over 45 years,
already having impaired productivity. The gross margin analysis shows a margin
of N2,046,844.00. The benefit-cost analysis shows a ratio of 1:1.56, indicating
that one naira invested in oil palm processing will yield N1.56. The production
has not been able to keep pace with consumption demand, hence Nigeria has to
import palm oil to fill the deficit gap. The highest output recorded in
research station was 13.50tonnes of fresh fruit bunch (ffb) per hectare. The
study shows that optimum replacement age of oil palm is 35 years for the
production to enjoy a flow of output. The major constraint being lack of good
policy direction and inadequate financial support and other incentives to boost
oil palm produce economy. It is recommended that there should be conscious
desire to implement research findings. The need to commission agency(ies) to
undertake the establishment of oil palm farms by government and after tending
it to certain age shall hand them over to private individuals on charge is
imperative. There is a need for credit policy to offer credit assistance to oil
palm producers. Oil palm producers should be encouraged to cut down their oil
palm at the age of 35 years.

INTRODUCTION
1.1
Background Information
Oil palm is a monocotyledonous tree belonging to the family,
palmae and the subfamily, cocoideae. The normal (diploid) chromosome number is
2n = 32. The adult plant possesses an impressive crown of 30 to 45 green
leaves, each 5-9m long at the top of a trunk bearing old leaf bases arranged
spirally, (Kochhar, 1976; Opeke, 1992; CTA, 2000). The stem may be 30 to 38cm
in diameter, with progressive thickening towards the base. On older palms, the
stem is punctuated with conspicuous and regularly arranged leaf scars and the
stem terminates in a handsome growth of leaves (fronds). The palm leaf is
compound and is known as the frond. The leaf is paripinnate with a prominent
petiole (0.9 to 1.5m long). The petiole often broadens at the base to form a
clasper round the stem. Each palm frond bears, 20 to over 150 pairs of leaflets
arranged in more or less two rows along each side of the flattened rachis with
the longest pinnate varying up to 120 cm. The pinnae are parallel-veined.
The plant is monoecious with separate male and female
flowers (inflorescences) on the same plant. Cross-fertilization is achieved
through successive cycles of male and female flower production. It produces
bunches of fleshy fruits, the pulp (mesocarp) of which yields a solid, edible,
orange-red oil called palm oil. The endosperm or kernel yields a clear,
yellowish oil, that is also edible and solid, and is called palm kernel oil.
These two products are important in world trade.
Oil palm adapts well to most textures from medium loams to
clays. Extremely coarse or fine textures may not always be suitable, especially
if they affect water supply to the roots. The climatic and soil requirements
constitute the physical factors that are responsible for the growth of oil
palm. They include availability of water supply, soil conditions in terms of
fertility and topography that is suitable for the growth of oil palm. It is
recommended that rainfall of 1600mm to 5000mm per year evenly distributed will
enhance the growth of oil palm, (Keu, 2001; Khera, 1976). The oil palm has a
wide adaptability range of soils to low pH but sensitive to high pH (above 7.5)
and stagnant water. Neutral pH soils are most favoured.
The temperature requirement varies between 180C and 340C.
Opeke (1992), observed that oil palm would tolerate even higher temperature
provided there is adequate moisture. It requires plenty of sunshine;
productivity is reduced in areas with excessive sky overcast. It thrives under
conditions of high relative humidity; yields are adversely influenced when the
crop is exposed to dry harmattan winds (CTA, 2000).SOCIO ECONOMIC GROWTH
Oil palm is a lowland crop although it can grow well up to
altitude of 900m. It has fibrous root system and benefits from deep soils which
are fertile, free from iron deposits and well-drained. SOCIO ECONOMIC GROWTH
Oil palm is affected by pests and diseases attack. The pests
and diseases attack both seedlings in the nursery and mature plants on the
field. Some notable pests of oil palm are snails, crickets and mammals especially
rodents (rats and mice). Others include leaf-minners, weevils, caterpillars,
birds and squirrels. The oil palm diseases include Anthracnose, Freckle, Blast,
Ganoderma trunk rot, Vascular wilt disease, Basal rot and crown diseases. These
pests and diseases pose serious problems to the production of oil palm. They
attack the plants at various stages of growth and development (Uguru, 1996;
CTA, 1998). SOCIO ECONOMIC GROWTH
In the 1950s and 1960s, Kogi State was a major producer and
exporter of palm oil and palm kernels
(about 12,000 tons or 2.40% of national palm kernel output)(Idachaba,
2005). At that time, he noted, there were pyramids of palm kernels in John Holt
Warehouses at Idah. Also, there was annual loading of palm kernels at Idah
River port for export through Delta Inland port of Burutu to Europe. Until
after the First World War, palm oil and kernels were supplied entirely from
groves of Africa and to a much lesser degree of Brazil. It was not until after
the Second World War that the West African groves were studied with
thoroughness. OIL PALM PROCESSING
Hartley (1988), postulated that in areas where the palm was
already part of the natural vegetation, the factors of greatest importance in
the development of a grove was the growth of a dense population. The cutting
down of forest areas for annual crop cultivation removed dense shade and
created conditions suitable for rapid establishment of the palm.
Because of economic importance of oil palm as high yielding
source of edible and technical oils, the oil palm is now grown as a plantation
in most countries with high rainfall (minimum 1600mm/year) in tropical climates
within 100 north and south of equator, (USDA, 2000). Raymond (1961); McCall
(2003), compared the potential oil yield from various crops and placed the oil
palm at the head of the list. OIL PALM PROCESSING
The extensive development of oil palm industries in many
countries in the tropics has been motivated by its extremely high potential
productivity. The oil palm gives the highest yield of oil per unit area
compared to any other oil crop and produces two distinct oils – palm oil and
palm kernel oil – both of which are important in World Trade, (USDA, 2000). Oil
palm seems to be part of the traditional agriculture of Kogi State. The climatic
condition and soil type of Kogi State appear favourable for the growth of oil
palm. The production and development is in the hands of small-scale holders.
They have all been dependent on rainfed cultivation and a large proportion of
the palm produced are on wild groves. Apart from the wild groves, three
economically important varieties are grown in the study area. These are the
Dura, the Pisifera and the Tenera. The Tenera is a cross between Dura and
Pisifera (Nigerian Institute for Oil Palm Research, NIFOR, 1985).OIL PALM
