CONSTRUCTION AND USE OF GROUND NUT SCREW PRESS.

By Naerls

Groundnut is widely grown in Nigeria. It is either
eaten cooked, roasted or processed into oil and cake (KuliKuli).
The oil and the cake produced are in high demand
in Nigeria. Groundnut oil production in Nigeria has been
reported to be in the hands of rural women who employ
mostly the traditional mortar and pestle grinding stone
which is considered to be energy-demanding and which
limits their capacity and output (yield).
One of the most difficult processing operations in
groundnut oil extraction reported by rural women is pressing
the cake to release oil. A simple manually operated,
low energy demanding and efficient screw press was developed
for use by oil producing rural women.
This bulletin is put together to assist local artisans
(fabricators) to fabricate the machine easily and for easy
use and maintenance by rural women.

GUIDE ON THE CONSTRUCTION AND USE OF AN A-FRAME FOR THE LAYOUT OF FIELD SOIL CONSERVATION STRUCTURES.

By Naerls

The Engineers' level has been the favourite Instrument
used for many years in the layout of soil con.:.
ervation structures on the field, such as the setting
out of contour lines for contour farming and strip cropping.
Similarly, it has been used for setting out terraces
on the field.

CHEMICAL FERTILIZER USE AND MANAGEMENT IN NIGERIA

By Naerls

Historically, crop production has been based on the use
of plant nutrients already in the soil. Soils however vary widely
in how long they can be cropped without yield reduction before
a given nutrient must be added. Nutrients are removed from the
soil by crops, lost by leaching and erosion fixed or immobilized
and should be replaced to ensure optimum crop performance.
The loss through crop removal (yield) is particularly un-avoidable
and occurs at every harvest. Nutrient losses by the other methods
can be reduced or eliminated completely by proper soil
management.
Fertilization is therefore mandatory with intensive use of lands
and with agricultural developments if satisfactory yields are to
be expected.

CHECK BASIN IRRIGATION METHODS FOR EFFICIENT WATER USE

By Naerls

Check basin irrigation is one of the five (5) primary
methods of surface Irrigation System. In this method, water is
applied to crops from supply channels by means of siphon tubes,
take-out pipe, diversion check etc. check basin irrigation is the
most common method of irrigation among irrigation farmers (both
large and small) operating in both large irrigation schemes and
the Fadamas in Nigeria.

CASHEW PRODUCTION AND PROCESSING IN NIGERIA.

By Naerls

Cashew (Anacardium occidentale L.) is a member of
the family Anacardiaceae, an ever green tree with spreading
large canopies which can attain the height of 9- 13 metres. It
was believed to have been introduced to Nigeria between 15th
and 16th Centuries by Portuguese explorers. The tree was
mainly used in afforestation schemes for the control of erosion
most especially in the Eastern part of Nigeria. Large scale
production of cashew however started in the early 1950's when
8,000 hectares of commercial plantations were established at
Oghe, Oji in the present Anambra State, Mba no in lmo State,
824 hectares commercial plantation was established in Upper
Ogun and other parts of Oyo State. Cashew grows in almost
all the ecological zones of Nigeria on an estimated hectarage
of about 40,000. Of this total hectarage about 24,000ha i.e 60
percent is owned by the peasant farmers, the rest by
government agencies

BULLETIN ON RABBIT MEAT PROCESSING AND UTILIZATION

By F. 0 . Oiowoniy An (mrs), H. Dikko (mrs.), et al

The daily consumption of animal protein by the average Nigerian
(less than 20 gms) is far below the required (39 gms) daily intake
as recommended by Food and Agriculture Organisation (FAO).
The urgent need to fill this gap calls for proven animal protein sources
which are not only nutritious but are cheap and readily available. In
this respect rabbit is highly favoured . The small and handy size of
the carcass, the quality of the meat and the wide range methods of
products preparation, make rabbit meat an excellent and economical
meat for us.

Wind Erosion Causes and Control (October 1999) (Extension Bulletin)

By National Agricultural Extension And Research Liaison Services, Ahmadu Bello University, Zaria, Nigeria

Soil erosion is defined as the physical removal of so ill from one location to another by either water and/or wind. Both types of erosions are further divided into many forms reflecting the processes involved. Wind erosion for instance is divided into: efflation effluxion, extrusion, detrusion and, abrasion. Others that relate to wind include sand- drift and dune- rise. Most of these forms of erosions are obtainable in parts of Northern Guinea Savannah, Sudan Savannah and Sahel regions of this country.

WHEAT PRODUCTION IN NIGERIA, EXTENSION BULLETIN No 62

By National Agricultural Extension And Research Liaison Services, Ahmadu Bello University, Zaria, Nigeria

Wheat is an important industrial and food crop. The crop is the main raw material in the flour mills. Wheat flour is used in Nigeria for bread and cake (85-99%). Semovita (1 0%), biscuit (about 4%), pasta (below 1 %), macaroni and spaghetti (below 1 %). Wheat is commonly milled at 75-76% extraction rate. The offals
(residues) are used in the feed-mills in compounding livestock feeds. The crop can also be processed for its starch content.

Water Quality Management In Fish Culture (extension Bulletin No. 98)

By National Agricultural Extension And Research Liaison Services, Ahmadu Bello University, Zaria, Nigeria

Fish culture involves the controlled cultivation and harvesting of fish for either family consumption or sales in the market. Although fish culture is over fifty years old in Nigeria, it is yet to develop fully when compared with arable agriculture and livestock production. A wide range of practices exist in culturing fish. Fish can be cultured in marine (seawater), brackish (mixture of sea and
freshwater i.e. lagoons) or freshwater (rivers, streams and lakes in the inland). In Nigeria, freshwater fish culture is more widespread than brackish water fish culture.

Vegetable Gardening in Nigeria Extension Bulletin Horticultural Series

By National Agricultural Extension And Research Liaison Services, Ahmadu Bello University, Zaria, Nigeria

This publication relates principally all the agro-ecological zones of Nigeria. In the northern part of the country which has a unimodal pattern of rainfall that commence between May and June, while the southern part of the country has a bimodal pattern of rainfall that starts around March and April. The commencement of the rainy season and amounts varies with the location within the country e.g. 670-1500mm rainfall if the average amount of rainfall in most of the Northern part of the country while in the southern part the amount received is over 1500-2000mm of rainfall annually. These variations influence the planting dates of most vegetable crops in Nigeria.

Tubwell and Wash Bore Irrigation Technology (Extension Bulletin)

By National Agricultural Extension And Research Liaison Services, Ahmadu Bello University, Zaria, Nigeria

A tubewell or washbore is an irrigation well consisting of a pipe with strainers inserted in a vertical hole drilled or bored to a specified depth that conveys water from an underground water source called aquifer to the ground surface. The pipe must either penetrate or hit an aquifer before the well could be a successful source of irrigation water. A tube well differs from a washbore mainly in the method used to drill and insert the pipe and on the depth at which the pipe is inserted.

Treadle Pump Use and Management (Extension Bulletin No. 97)

By National Agricultural Extension And Research Liaison Services, Ahmadu Bello University, Zaria, Nigeria

The treadle pump is a simple, manually foot operated pump designed to lift water from shallow wells and surface sources for irrigation or domestic purposes. The pump is so called, because treadles (which are lever devices pressed by the foot to drive machines) are used.
