Improvement in Crop Yields Video Lecture | Crash Course: Class 9 (Hinglish)

hello friends this video on improvement
in food resources part 1 is brought to
you by exam feel calm no more fear from
exam topics to be covered in this lesson
our improvement in prop yells crop a
variety improvement crop production
improvement wherein we'll talk about
nutrition management nutrient management
manuals and fertilizers irrigation and
cropping patterns crop protection
management animal husbandry which would
include cattle farming poultry farming
egg and broiler production fish
production and beekeeping so what do you
think are we going to study an
improvement in food resources right
quite a simple name very easy to guess
what is the content of the lesson right
so be able to talk about food resources
what strikes your mind when you think of
food right these are things which we eat
maybe since all of us live in different
parts of the world so we all of us have
different food habits some of us eat
maybe rice vegetables more of curries
many of us are even non-vegetarian so we
even consume fish egg chicken meat and
things like that so we have a variety of
food which we actually consume so when
you think of those food what all comes
to our mind may be things like bread
rice variety of vegetables a variety of
fruits make all these these are the
things which we actually eat now from
where do these things come from we
obviously get them from our nearby shops
or vegetable markets but where are they
actually grown they are actually grown
in some field where people are involved
in agriculture the farmers farmers are
growing crops right and from there we
are actually getting these food
materials
so maybe many of us are not much
bothered about from where it is actually
coming we are only the consumers right
but being the consumers who are
dependent on these different food
materials we should be concerned about
the origin of these food materials so
from where are these crops being
produced right so when we think of the
crops which are produced in the fields
what all comes to our mind things like
wheat rice means they are all produced
in the fields so many vegetables which
we see they are also grown in fields
right so if if people stopped growing
these vegetables if they stopped growing
fruit if they stopped growing the crops
we will not get anything to eat right so
in this lesson what we are trying what
we will be trying to know is how can we
improve the food resources that means
how can we improve the way in which the
crops are cultivated so that we get the
best quality food so that we get best
quantity of food now why are you
striving this lesson that is the agenda
of the next slide but why do we need to
improve crop hence what is crop yield
that means the amount of crop which is
getting produced so why do we want that
we need to improve the crop yet that is
the agenda of this lesson that how do we
improve the food resources how do we
improve the production of crops how do
we improve the quality of crops so that
is that enough so why do we even need to
improve anyways there are people who are
involved in agriculture they are growing
crops they are growing vegetables fruits
and whatever we need we are getting them
and we are surviving so what is the need
so the first and foremost need is the
growing population so now as the
population is increasing the demands of
the people are also increasing for
example if there is a family where you
have maybe
two members a person and his wife right
so now whatever the person is earning he
has to feed himself and his wife
correctly now let us suppose he got kids
so he has one kid now so his family the
number of family members increased from
two to three
now suppose he got one more kid so his
family increased from fifty to four so
now if you see as the family keeps
increasing the amount of food that is
needed for their survival
that also increases so as the population
increases the need of food also
increases so so at one pace the
population is increasing right the other
piece the crop yield should also
increase that means the amount of crop
that is being produced should also
increase otherwise it will not be able
to meet the demands of the growing
population right so that is one
important reason why we need to improve
our crop yields right now another thing
is now you might think that okay fine if
we want to increase the crop production
let us put more land under cultivation
because as you see not all the lands
which we see around us are used for
agriculture right some of them are used
for industrial purposes some of them are
used for residential purposes some of
them are used for building roads
infrastructure more and Spelling's and
things like that so a certain portion of
the land is used for agricultural
purpose so now suppose you might think
that okay then what we can do is we can
put more land for agriculture now there
also in India we have less scope that's
that's because in India already
intensive cultivation is done that means
already a good portion of land is being
involved in agriculture so now we cannot
put the entire land on agriculture right
because there are others terms also
which we for which we need land so we
cannot put the whole amount of land only
for agriculture correct so so the first
thing is that the population is
increasing even now so India is a very
popular
century right so the population is
continuously increasing so and also we
do not have the scope of increasing the
cultivation area so that means the area
is remaining almost fixed but the number
of people are increasing so that means
within that same area we need to
increase the production of crops so how
do we do that so that is the main
objective of this lesson that how do we
increase the crop production or how do
we increase the crop yield in that
specific that in that much area of land
without introducing the area of land how
what are the different ways by which we
can improve our crop productivity now
again there are many techniques there
they're mainly technologies and many
different things have come up which can
improve the crop yet but again we have
we see that in most of those cases they
affect the environment that means by
using those techniques the crop
production definitely increases but at
the same time it pollutes the
environment so that means in one way it
is advantageous but at the other way it
is doing something bad to the
environment now if the environment is
getting polluted again it is affecting
us only right so now we have to strike a
balance between the two we have to imply
some techniques which can increase the
crop yield at the same time we have to
take care of the fact that it should not
harm our environment to a large extent
so we have to make a balance between
them so now we will see what what are
the different ways which we can actually
implement in order to improve the crop
yet
right so I hope it is clear that why do
we need to improve the crop yet now does
that mean that improving the crop yields
alone will solve the problem of
malnutrition no before that
what does malnutrition may be all of you
not aware of the term malnutrition means
somebody who is deprived of proper
nutrition for example
at every age we need certain amount of
nutrition to live healthy right but
there are a lot of people who do not get
enough healthy food and that is why they
suffer from malnutrition that means they
suffer from deficiency of nutrition
which leads to many different kind of
diseases now mostly malnutrition is seen
in children who do not get proper food
and therefore they get many diseases
right so now in India we have this
problem of malnutrition and hunger there
are a lot of people who are below the
poverty line right and they suffer I
mean they do not get proper food so do
do you think that by improving the crop
yield that means by by applying some
techniques what all techniques that we
will study in our coming slides but do
you think that just by improving the
crop production that means just by
producing a lot of crops good quality
crops will that solve the problem of
malnutrition
well that alone is not going to solve
this problem so improved crop yields
alone cannot solve the persisting
problem of malnutrition and hunger so
this alone cannot solve by that's
because it is suppose we have improved
the crop kills so a lot and lot of crops
are being produced so many fruits
vegetables cereals everything so if
everything is there right but how do you
get or how do each of us get these
things in order to get these things we
need money right when you go to a shop
to buy something say 1kg Apple the
shopkeeper is not going to give it to
you for free you need to pay him right
so you need to have money so that means
good economic condition has to be there
to ensure affordability
so now by improving the crop here what
we are doing we are making the food
resources available in the market but in
order to afford those food materials one
should have money so good economic
condition
is necessary to ensure that the food
materials which are being produced are
affordable to each of us right now how
do we ensure good economic condition
better income to those involved in
agriculture now as far as India is
concerned a good amount of our
populations involved in agriculture as I
said since a good amount of land is also
given for agriculture similarly you have
a lot of farmers right so whenever you
go to a village you will see so many
farmers are there right so a huge a good
portion of our population is dependent
on agriculture and that is their earning
that is how they earn now it is seen
that the pay which they get where by
doing work in agriculture is very less
now when you get less when you earn less
you cannot afford to buy very expensive
vegetables right so what will happen so
even though there are lots of vegetables
there are lots of fruits at the market
but you do not have enough money to buy
them so they are not affordable to you
and as a result the problem of
malnutrition and hunger will still
persist so in order to solve the problem
of malnutrition and hunger two things
need to be taken care of
one is improved crop yield so that food
resources are available in the market
and the second is good economic
condition people should have enough
money and for that people should get
decent salary or decent earning in
whatever they do but in India we see
that if there is a lot of
differentiation in the as far as wages
are concerned right as I mentioned
before also that there are so many
people who are below the poverty line
not only that there are so many people
who are involved in agriculture or these
kind of work that the workers which who
work in mines or agriculture or
construction buildings so they get very
late less wages per day so now when you
earn very less many things become
unaffordable to you
so these are the two things that need to
be taken care of to solve the problem of
malnutrition and hunger in India one is
improved crop yield next is good
economic conditions thank you
