any time you skip this video you miss
one step or the other if you have any
question to ask please I want you to
leave a comment on the comment section
and I promise you that I will answer you
as soon as I get notification on your
questions on today's edition I want us
to look into this year's um Agricultural
Science spacement for wak 2024 so and um
assistance few days ago or few weeks ago
I was able to post some of the Spacemen
um before it um it got circulated online
so for those of you who um got the
spacement two weeks ago I must say
congratulations and for those of you who
I was unable to reply on time I must say
sorry for not being able to reply you
because the messages I was getting was
so much and I cannot reply all those
messages and what I did was I had to
reply one person and pin it so that once
you come um once you are done watching
the video you'll be able to see the the
message and then the spacement which I
sent the and here I have them a ranging
pole I have Arrow I have measuring tape
I have a wooden Peg I have a dry um sand
which is a sandy soil I have a um dry
clear and I have dry LOM soil yes I have
dry l so and um here I have um maze
Weevil and um here I have bean we Bean
beet
grasshopper lastly cotton Stenner so
from here now we have from a 2 K so we
have about 1 2 3 4 5 6 7 8 9 10 11 about
11 Spacemen to look into So and I've
been opportuned to go through this Spen
and I've been able to solve this um
specimen in order to deduce some of the
answers or questions that you may likely
face in this y 20 um 24 as far as as
well as the Practical that are involved
so all I want you to do is just pay
attention do not skip this video
remember when you skip this video you
may end up losing one step or the other
and by the time you try to do your own
you may not be able to get the right
answer so on specimen a which is ranging
pole yes ranging pole so in this 2024
exam W expects you to be able to
describe this um simple to which is
simple too known as ranging pole so if
you're able to describe it very very
well that ends you your mark So under
this description here I said a ranging
pole is a simple tool used in surveying
land to measure elevation distance used
in combination with other severe
instrument like toite so this um ranging
pole is a measuring instrument used in
combination with other survey instrument
known as um toodo light now let us look
at the uses of this um ranging pole so
one of the uses of this ranging pole is
here I said it is a survey instrument
used for marking the position of
stations yes it is used in marking
positions of stations that is number one
again it is used for sighting of those
station they use for sighting of those
station it is used for ranging straight
lines it is used for ranging straight
lines and again there is something that
you must not fail to understand ranging
poles are mostly painted with red and
white they are mostly painted with red
and white so w will may ask you what is
the reason why they are been painted red
and white the reason why they have been
painted red and white is so that it can
be seen from afar yes it can be seen
from afar that is the only reason why
ranging poles are mostly painted with
red and white
colors okay so that is for ranging pole
okay now let's take a look at the
specimen let's take a look at the
specimen B which is Arrow which is Arrow
okay so in this spacement W will also
expect you or be asking you to describe
specimen B they will ask you to describe
specimen B so all you need to do is just
give them a little description of the
specimen B even if you don't have it up
hand for the fact that your teacher has
provided you with the SPAC which is on
the screen now known as the arrow you'll
be able to describe it just the way it
is do not add do not remove because they
already know what what they have given
to you so from here now I I under my own
description I said it is a metallic long
coughed simple surveying tools used for
surveying during counting of chain when
measuring chain lines I repeat I said it
is a metallic long cved simple tool used
for surveying during counting the number
of chain when measuring a chain
lines so that is the description of um
an arrow that is the description of
Arrow so now let's take a look at the
uses you may be asked to State the uses
of this um Arrow which is specimen B one
of the uses of this Arrow known as
specimen B is it is used for counting
the number of chain while measuring a
chain line just as we have lifted it in
the description so whenever you are
given a description I would like you to
State little about what that particular
material is being used for especially
when you there is no option for you to
State the uses of the material it is
very very important and that will help
to end you a better Mark than when you
just State without saying the
users okay so that is by the way way now
let's take a look at a measuring tape
which is specimen C specimen C is a
measuring tape yes it's a measuring tape
so on that very day if you are a student
watching this video your teacher is
meant to provide all these materials for
you that very day of the exam place it
on the table and label them as W has
given in their spacement so here let us
look at because w will not begin work
will not ask you to begin to describe a
measuring tape no they won't go to that
extent so what they are looking at is
for you to be able to State the function
what it is used for that is for
spacement C which is a measuring tape
and here I said it is a measuring tape
used for survey to measure distance and
size it is a survey equipment or
instrument used to measure distance and
size of a particular environment or a
farm land so when you want to measure
your Farmland you don't use any other
thing than using um a measuring tape
okay so that is the them one of the
things you are expected to know as far
as measuring tape is concerned though
you may still be asked to States how you
can be able to care or maintain these
instrument but in this um teaching I
will take all of them together because
sometime I will point out spacement a
SPAC B SPAC C and ask you to State their
um maintenance all of them have the same
maintenance so that is the reason why as
we progress I'll be able to tell you how
you can be able to maintain these
materials based on the questions W will
ask you bear in mind that everything I'm
telling you in this channel believe you
me you will see 100% of it the way I am
saying it is the way it is going to come
out there is no two ways about it okay
now the next one we have here now is
wooden peeg we have wooden peeg which is
Spacemen D specimen D is known as a
wooden Peg and here we said under the
wooden Peg all you are expected to know
is the uses okay or the function the
function or the uses now here I said it
is used to Mark out residential bandar
is used to indicates point and positions
of sight that is another function of a
wooden Peg it is used to indicate points
and position of sight
let me repeat it again wooden Peg one of
the function or uses of wooden Peg is it
is used to Mark out
residential um boundaries and also it is
used to indicate point and position in a
land
surveying okay now here note that a b c
d are simple survey Farm two all these
that I've mentioned now their general or
their common use or usage is for land
surveying is for land surveying please
take note do not forget this it's for
land surve okay now let us look at the
maintenance of Spen a b c and d so we're
going to be taking a look at their
maintenance how you can be able to
maintain the
in case if you are asked to mention the
or state how we can be able to maintain
either a B or C or possibly combine all
of them and ask you to mention mention
the way you can maintain them these are
all the same is a general form of
maintaining the tools the suran tools
which we have mentioned earlier okay
here we have ensure they are washed and
stored in a cool dry place which means
after you must have finished using it
you wash it off especially those on that
have sand contact you wash it up and um
clean it and store in a cool dry place
okay here here it says check regularly
to inspect any damaged part so after you
must have finished um making use of
these materials you have to um check
them at regular interval even where you
store it check if they are they
beginning to rust or something has cause
a damage on the tools so that you can
easily replace it before it escalates
now the next one there says lubricate
metallic Parts after use most of these
um tools are metals apart from the
wooden peeg every other one is um is
metal even sometimes applying oil on
wood to avoid the attack of incense like
thite is also um encouraging so for
those ones that are metallic in nature
just like the ranging pole after use you
have to wash and lubricate the metallic
part so that it will not
rust okay now next last one here says Ed
to for the for the purpose it was made
you must use the tool for the purpose it
was made so this are the ways in which
we can be able to maintain this Farm um
this um survey instruments this survey
instruments so that is by the way now
let us go
to
Spen e let us go to space
e so before the specimen E I want us to
run down every other specimen so that we
go back to this and I will show you how
you can be able to set up your your
capillary um to so that you can be able
to achieve the um purpose at which you
were given the spacement for okay now
here let's take a look at Spacemen
hedge let's take a look at Spen
hedge now under Spen hedge we have maze
WS we have maze WS okay so this maze
wvil what they attack is grains that is
maze okay that is what they attack maze
okay so now if you look at this you will
see the drawing them now W is expecting
you to know how they feed that is their
mouth Parts what kind of what pattern do
they feed on are they boring incense are
they piercing and sucking incent are
they biting and chewing incense now if
you watch closely you will discover that
um this m w they the the way they attack
grain is their amount is they have a
pointed mouth they have a pointed mouth
that enables them to make home to B into
that particular um maze so the M part
Here is known as boring boring mouth
part boring mouth part that is for the
maze waivers please do not forget this
because everything I'm teaching you here
now you must surely see it in your
question paper as far as this practical
is concerned so I want you to pay
attention and also do not forget to
share this video to your brother to your
friends to anyone who will be writing
Agri of w this time around so that they
can also
learn okay now the the next one we have
here now is Spacemen l i sorry next one
we have here is spacement I which is be
B we have bean B now what kind of incent
is that this incent is also known as
kind of M part they
possess okay now specimen J we
have
grasshopper we have grasshopper now
under grasshopper grasshopper is a kind
of incense that bites and chew so the
incent type is known as biting and
chewing
insect get that when you see anywhere
they ask you what type of incense is
Spaceman hedge the type of incent is a
boring is a biting and chewing incense
that is for the grasshopper because
their mouth is made up of the mandible
and the mailia that enables them to bite
and chew plant
parts K which is scotting Stenner now
the type of incent which is cutting
Stenner
is known as piercing and sucking incent
cotton Stenner is a piercing and sucking
incent which is the incent type piercing
and sucking incense
okay now let us look at the effects the
effect of both specimen H which is m w
specimen B that spacement I which is Bim
spacement J which is Grasshopper And and
specimen K so we want to look at the
effects their effects in agriculture in
agriculture now here we said it reduces
the viability of crops it reduces the
viability of crop due to their AB bite
due to their bite it causes those
particular grains which has been
attacked not to be viable which means
they will no longer be healthy for
planting some of them when you plant
them they will not be able to germinate
because it has been attacked it has been
destroyed everything in it their cut
Lions has been destroyed by these
incense that we have mentioned above the
secondly it causes damage to stores
grain it causes damage which is that of
bimu and mze W they cause damage to
stored
grains Okay now now here we said each
attack each attack reduces the market
value of plant
produce each attack reduces the market
value of the plant produce that is to
say that when these plants when these
grains has been attacked by this
incense they make the plants to be
unattractive to the buyers and if a
buyer wants to buy or managed to buy it
the value at which the crop will be
placed when it is still healthy will
reduce as a result of the attack of this
incense so that is one of the effect now
another one there says it increases the
cost of production in controlling them
it increases the cost of production in
controlling them and here we says um it
can cause plant or crop disease
this plant this um incense can cause
plants or crop disease once they carry
when they attack your crop they end up
exposing those crop to diseases and most
of them are vectors of disease okay now
here we say it can result to economic
loss for the farmer it results to
economic loss of the farmer once they
attack your crop there is every
possibility if care is not taken or if
um it was not noticed on time it may
lead to a lot of economic
damage here says it makes the crop look
unattractive it makes the crop to look
unattractive so those are the effects
those are the effects of these incense
that we have mentioned above which is
SPAC head Spen I
and
spacement okay SPAC head SP I SP J and
spacement K now let us look at how to
control them now here we says we have
chemical control chemical control under
chemical control we have the use of
incen the use of incen side is one of
one way through which we can control
these incense chemically here we have
cultural means of controlling these
incense here we have early planting
early planting is one of the ways
through which this incent can be
controlled now we have early harvesting
early harvesting is also a way through
which this incent can be controlled now
we have crop rotation crop rotation is a
good way through which this incense can
be controlled now we have um planting
resistant crop that is you plant crops
that this particular incense cannot
attack or does not feed on so when
Farmers plant in plant such crop in
their Farm or sto such kind of grain you
will discover that those incense like
grasshopper B and then B will not be
able to attack those
crops now another one there says
destroying or burning infected crops
destroying or burning infected crop so
when you discover that a particular crop
has been infected all you need to do is
you destroy it or you set it a blaze so
that you can be able to destroy their
lava as well now the next one they says
under mechanical control we have hand
pick
hand picking you begin to pick them one
after the other though it takes time now
here we says store in Dry St dry in bag
and cans you make sure that the crop you
dry it very very well especially the
grains dry it very very well before you
store it in cans and in bags with this
you can be able to control spacement
head H specimen I specimen J and
specimen K okay so that is by the way
let us look take a look at specimen L
specimen L which is
tilapia tilapia fish which is a fresh
tilapia fish fresh tilapia fish now this
is the drawing of a fresh tilapia fish
now here we have the nose trees we have
the eyes we have the mouth we have the
Gil cover we have the pictorial FS we
have the pictorial pelvic things we have
the Ana F we have the c f and we have
the DOA things as well as the scales and
the lateral lines the lateral lines
now here we have gears used for
harvesting specimen L gears used for
harvesting specimen L one of the gear
used in harvesting spacement L is hook
next
fish STP and baskets so when you want to
harvest them these are the girls use a
harvesting span L these questions must
surely come out take it from me whether
you like it or not these are the things
you are going to see so please remember
I said earlier get your pen and paper so
that you will not say that you did not
hear and also Al remember to share this
video to your friends and long ones so
that they can be able to partake in this
lesson okay now the next one there says
product that can be made from L products
that can be made from
L under the product that can be made
from L we have fish meal from this um
fish we can get fish meal we have um
bones we use it in making bones we have
use it in making meals that is cooking
meals we can extract the oil from the
fish as a cooking oil then this fish
also serve as a raw material to
pharmaceutical industries that produces
drug it is a good source of um um drug
it is a raw material for drug production
okay now here we
says this um til can be read in pond
Lake and stream that is where we can
find them that is where it is found
stream Pond or lake that is for that now
let us look at specimen M which is ha
specimen M which is ha now under ha
let's take a look at the uses of hay
what is you um hay used for that is the
question you are going to see in the W
exam yeah we say it is used as a roofing
material it is used as a roofing
material some some of these um people
that build starch houses they can use
hay in making their roof also here it
says for nesting and beding area for
Animals it is used for bedding and Nest
making
in animals that is for the ha here we
say it is used to cover up
patches it is used to cover up mod
patches it is used to cover up mod
patches now here we said it is used to
cover newly planted crops for neries for
neries we use it to cover the top of the
um areas where you made your
Nery now here we say it is used for
mching it is used for mching in order to
prevent excessive loss of water from the
soil is used for
mching here says it is used to create
walkway in farm it is used for to create
walkway in farm here we say it is used
for mat making when it is being
processed it can be used for mat making
all this local mat we see
around us now here we have specimen n
which is fish meal speci M which is fish
meal now under this fish meal what w is
expecting you to know is how to make
fish meal nothing more nothing less how
to make fish meal and uses of this fish
meal these are only two things that is
expected Ed of few so let us take a look
at what it takes to make a fish
meal now here when you get the
fish first procedure that is taken is
cooking you have to cook the fish very
very well in order to kill bacteria in
the fish and also to denature the
enzymes inside the fish that is number
one procedure cooking now number two
procedure is pressing pressing after the
fish has been cooked properly the next
thing there is it is now put in a
machine in order to press it just to
remove the oil and water in the fish now
the Second Step there is drying after de
pressing the next thing there is it is
now kept Under the Sun or under a heater
so that it can properly dry before the
second step which is grinding during
this process the fish is grinded into
fine powdered form one there is
packaging after the grinding the fish
meal is now put into a secured
environment like packaging it into bags
into cans until it is used so that is by
the way now let's take a look at the
uses of this fish meal one of the uses
of this fish meal is it is used in
feeding farm animals it is used in
feeding farm animals like fish poetry
and other farm animals now the next one
there is let's take a look at the
nutrient content why will be asking you
about the nutrient content of this fish
meal one of the nutrient content of this
fish meal is protein fats and oil these
are things you need to know about about
fish meal
