Who is horticulturist? Job scope, course process in India, salary

What is horticulture?


The person who has an interest in nature may have the best choice for them to choose horticulture as an career option. Now a day horticulture is top growing career field. If we talk about a proper definition of horticulture then it can be defined as follows.

A horticulture is a branch of a agricultural science where you will study about the plantation of fruits, vegetables, and seasonal dry fruits. Horticulture is not similar to agriculture. Horticulture is done by a horticulturist in a specific environment. 

Means in horticulture we planted fruits and vegetables in a specific area with suitable environment. If the environment is not suitable then we can make it suitable for us by technology.

But if we talk about agriculture. It can be done in any area where only water and sunlight is available. There is no any need of a specific temperature and environment as needed in horticulture.

Hence, the main difference between agriculture and horticulture is that in agriculture we need not to manage soil and environment but in horticulture we need a suitable soil and environment.

Now, this was the information about horticulture. But how can we get job in horticulture. Means how to become a horticulturist? So let's discuss this in detail.

If we talk about the branches of horticulture. Then it has four branches.

  1. Pomology:- In this branch of horticulture you will study about fruits and vegetables.
  2. Floriculture:- The branch of horticulture that deals with the cultivation of flowers.
  3. Spices and plantation crops:- this branch of horticulture are in more demand in mountain area. In this branch a horticulturist grow black paper, coffee, vanilla etc.
  4. Medicinal and aromatic plants:- This branch of horticulture deals with those plants which is used in making medicine and cosmetics product.

What is horticulturist?


Horticulturist is a term made from horticulture. If a person got jobs in the field of horticulture then that person are called a horticulturist.

In simple words, if anyone did a course of horticulture after 12th. And clear the entrance exam of horticulture can become a horticulturist.

Who is horticulturist?


Horticulturist is a person who studied about plant seed and vegetables. Means that those people who experts in cultivation and farming of fruit seed and vegetables seeds. Basically their main work is to maximize the growth of fruits, vegetables and also protect them from insects.

A horticulturist works on the research and development of fruits and vegetables. In other words, a horticulturist is a scientist of plants, fruits and vegetables. Their work is to study on the seed of fruits and vegetables to maximize the production.

  • A horticulturist can also develop two plants in one roots.

What is the difference between horticulturist and gardener?


The main difference between a horticulturist and a gardener is that a horticulturist is well educated professional Gardner. But a simple Gardner is one who take care of plants.

Basically both a horticulturist and a gardener takes care of plants. But one with a great knowledge and other are not.

  • A professional horticulturist can also maximize the production and growth power of the fruit's seeds but a simple Gardner can only take care of that plant after growing.

  • A horticulturist uses their knowledge and research in the growth of fruits and vegetables while a simple Gardner are not do so.

State the relation between electric field and potential E = - dv/dx

State the relation between electric field and potential E = - dv/dx

State the relation between electric field and potential with Derivation

After the lots of discussion on relation between various terms and things. We came accross the chapter electrostatic. In electrostatic chapter class 12. There are also many relation exist. But not all, here we only discuss about electric field and potential.

Electrostatic is a concept of electric charge at rest. Let's elaborate it in more details.

As we know when the charge is moving then it is called electric current. But when the charge is at rest in one place and can not be moved until or unless external force can be applied then it is called electrostatic. 

So here are the list that we will learn in this post.

  1. What is electric potential.
  2. What is electric field.
  3. Relation between electric field and potential.
  4. Derivation of relation between electric field and potential.
  5. Examples of electric field and potential.

So let's start with the meaning of electric potential.

What is electric potential in simple words?


Electric potential is basically referred as the value that we get after bringing a unit charge from one point to another point in an any electric field value.

In simple word, In those reasons where there is some electric field experiences. In that area, if we move a unit charge from one point to another point then work is done. So that amount of work is done per unit charge is called electric potential.

Please keep in mind while moving a unit charge in an area where electric field experiences. You have to maintain the velocity of unit charge. That means do that movement of unit charge in such a way that no any acceleration can be produced.

What is electric potential in simple words?

In the above fig. as you can see there is a unit positive charge brought from infinity to a fixed point in an electric field. So due to this movement of unit charge some amount of work is done with respect to the change. 

So we can say that this value of work done is equal to electric potential.

More depth concept of electric potential


In a concept of electric potential. We have observed that we always bring a unit charge. So what is that charge means? How we bring it from one point to another? To know all these underground questions. Please read further more.

To calculate the value of electric potential. We use the value of work done. Right! 

Now, the question is, can we use a non unit charge. The answer is yes. We can use any amount of charge in electric potential. 

Let's see how we move that charge from point to another point. So to do that we use a medium that can conduct electricity. 

Suppose we have to bring a unit charge from one point to another. Now in that case here we are using a copper wire. 

In case if we have to join two copper wire end to end then the electric potential at both the wire are equal.

What is an electric field simple definition?


In simple words electric field is the field or that area where some electric field lines are available due to some charged body present there. Or you can also say that those reason or area where there can be some force experienced or detected by another object.

For example, if a body comes closer to an area where some electric field present then that body experience some force which is called electric field.

Suppose you have an area which is rectangular in shape having some electric field. Because there is a charged body present. 

Now, if we bring something that can experience electric field lines. That body will experience some force . So that reason are known as electric field.

State the relation between electric field and potential E = - dv/dx

In the above fig. There are some electric field lines present due to two charges one is positive and other negative.

Now, let's suppose we bring a magnetic compass near it. Then in that case the needle of the compass deflected. That means some force has experienced.

Please note that if we come closer to the charge the electric field force increases but while going down or far from the charge then electric field force decreases.

State the relation between electric field and potential


As we have discussed above about electric potential and electric field. In the above discussion we can easily observed that the concept of electric field will not be complete without electric potential. Because If there will be no any movement of test charge from one point to another then there will be no any generation of electric field. 

So electric potential difference is necessary for the generation of electric field. About this little discussion we have conclude that there is something quite a relation exist between electric field and electric potential. means there is a quite connection exist between these two terms.

So this the only conceptual ways of looking a relation between electric field and potential. But now, lets see a mathematical relation between them.

Hence, the mathematical relation between electric field and electric potential is that electric field will always be equal to the negative gradient of electric potential. here gradient means nothing but a small length that a test charge travels from one point to another point.

E = −dv / dx

Please note that the relation between electric field and potential is also known as the relation between electric field and potential gradient. i.e, E = −dv / dx is same for relation between electric field and potential gradient.

lets understand the above relation in more depth ways.


In the above formula of the relation between electric field and potential. 'E' represents the electric field, minus sign represent that the particles moves in the direction of electric field intensity, 'dv' represents the small electric potential, 'dx' represents the potential gradients.

Derive the relation between electric field E and electric potential V.


To derive the relation between electric field and potential. We have to prove the relation between electric field and potential gradient. i.e, 

E = - dv / dx

Now, let's consider a +q charge on a point P. From some distance say (x). Let's consider another charge q.

When we will trying to being this charge q towards +q. The magnetic field of +q exert a repulsive force in outward direction that can be denoted by E.

As we know for bringing the charge q we have to do work done.

Work done (w) = F. S

For small movement of charge by distance dx.

The work done dw = f. dx ---------(1)

As we know electric field (E) = f / q

F = E q ------------- (2)

Put the values of F in equation 1.

dw = Eq . dx

dw = q E dx cos 180

The value of angle is 180. Because the angle between electric field (E) and movement of charge (dx) is 180 degree. Means both are in opposite directions.

dw = q E dx cos 180

dw = - q E dx -------------- (3)

As we know the formula of electric potential is 

V = w /q

For small distance dx.

dv = dw /dx

dw = q dv -------------(4)

From equation 3 and 4 we get,

-q E dx = q dv

- E dx = dv

E = - dv / dx

Hence, it has proven that the relation between electric field and potential gradient. i.e, 

E = - dv / dx.
