Chapter-1 Crop production and management - Extra Questions

Explanation:

Irrigation is the artificial method of giving plants water to help them grow. Wells, tube wells, ponds, lakes, and rivers are the primary sources of irrigation. 

We can help conserve water in two ways: 

(i) A system of sprinklers: The vertical pipes of this irrigation system are arranged with rotating nozzles at the top. It is more useful on uneven, sandy land where there isn't enough water. 

(ii) System of drip irrigation: To water plants one drop at a time, just at the root's base, this irrigation system uses a system of pipes or tubes with tiny holes. Since no water is wasted, it is very effective. 

Explanation:

Between November and December and March and April, wheat is sown. It grows in the winter and needs less water to grow. Production of wheat will significantly decrease if it is planted during the Kharif season. 

Explanation:

Because the crops absorb nutrients from the soil, continuous crop planting depletes the soil of certain nutrients. Infertility occurs in the soil. It doesn't have enough time to get the nutrients it needs. 

Explanation:

Weeds are undesirable and undesirable plants that naturally grow alongside the crop. There are a lot of ways to stop weeds from growing. Before planting crops, tilling helps kill and uproot weeds, which may then dry out and mix with the soil. Using weedicides, which are specific

chemicals, is another method of controlling weeds. In order to eradicate weeds, weedicides are applied to the fields. 

Explanation:

Sowing is the act of putting seeds in the ground. The funnel-shaped tool that is traditionally used for sowing seeds These days a seed drill is utilized for planting with the assistance of farm trucks. The seed is sown uniformly at the right distance and depth with this tool.

Explanation:

Crops are plants of similar kind filled in huge amounts for food. 

Explanation:

Crops in our nation are categorized according to their growing season. 

Explanation:

Kharif crops are those that are grown during the rainy season and harvested in September or October. 

Explanation:

Summer crops, also known as zayed crops, are those that are grown in the summer and harvested before the rainy season begins. 

Explanation:

Rabi crops are those that are grown in the winter and harvested in March or April.

Explanation:

Paddy can only be grown during the rainy season because it requires a lot of water.

Explanation:

The actions that farmers take over time to cultivate crops are referred to as agricultural practices.

Explanation:

By Tilling, or turning and loosening the soil, prepares the soil. 

Explanation:

The uniform distance between the seeds and their proper depth beneath the soil are advantages of using a seed drill to sow them. 

Explanation:

Fertilizers and manure are the substances that are added to the soil as nutrients for plants' healthy growth. 

Explanation:

Plants need water for the following reasons: 

● The roots of plants absorb water-soluble nutrients. 

● Water plays a role in the process of seed germination. 

● It shields the plant from hot air currents and frost. 

Explanation:

The following are advantages of using an irrigation sprinkler system: 

● On uneven land where less water is available, the sprinkler irrigation system is useful.

● It helps save water.

● On uneven land where less water is available, the sprinkler irrigation system is useful.

● It helps save water. 

● It helps with the sandy soil. 

Explanation:

● Plough: This tool is used to till the soil, add fertilizer to the crop, get rid of weeds, and scrape the soil. 

● The hoe is used to loosen the soil and get rid of weeds. 

● Ploughing with a cultivator

Explanation:

● It makes it possible for the roots to get deep into the soil. 

● It aids in the development of soil microbes and earthworms. 

● The dead organisms release a variety of nutrients held in the soil. 

Explanation:

Irrigation refers to the process of providing crops with water at regular intervals. There are two types of irrigation: 

● A sprinkler system is one in which the crops are sprayed with water as if it were raining.

● Drip system: In this type of system, water falls one drop at a time right at the roots. 

Explanation:

● Crop rotation 

● Field fallow 

● Mixed cropping 

These are the three natural strategies for replenishing soil nutrients. Farmers must use manures and fertilizers because these natural methods are insufficient. 

Explanation:

● Roots are able to breathe because loose soil has a lot of air trapped in it. ● The roots can get deeper into the soil when it is loose. 

● Microbes and other organisms thrive in loose soil. 

Explanation:

(i) Keep your mouth and nose shut when spraying pesticides. 

(ii) The farmer should be positioned so that the wind doesn't blow in his face.

(iii) Water should be used to clean the mouth, face, and hands immediately following spraying.

Explanation:

Organic manure offers the following advantages: 

● It improves the soil's capacity to hold water. 

● It makes the soil porous, which allows for gas exchange. 

● There is an increase in the number of friendly microbes. 

● The soil's texture is enhanced by the organic manure. 

Explanation:

The soil must be turned and loosened in order to prepare it.Ploughing is the process of using a wooden or iron plough that is pulled by an animal or by tractors. Then, a wooden or iron leveler is used to level loose soil. 

Explanation:

For the purpose of increasing production, manure is the decomposed form of dead plants and animals. It is a characteristic type of compost and is savvy. Manure is also made from the excrement of humans and animals. The livestock manure is loaded with potassium, nitrogen, and phosphorus.

Because it contains a lot of humus and organic matter, manure makes the soil more fertile. In the long run, these are superior and do not pollute. It is a valuable resource that can be used again.

Explanation:

In order to boost the productivity of crops, fertilizers are added substances. Every day, farmers use these to increase crop yield. The plants need nitrogen, potassium, and phosphorus, which are contained in these fertilizers. Additionally, they increase the soil's fertility and capacity for water retention.

Types:
Composts are chiefly arranged into two fundamental sorts, natural and inorganic fertilizers:

Organic Fertilizers Organic fertilizers are natural substances derived from animals and plants. It enriches the soil by adding carbonic molecules that are necessary for plant growth. Organic fertilizers alter the soil's physical and chemical composition, encourage microbial reproduction, and increase the amount of organic matter in the soil. It is regarded as one of the necessary components for green foods.

Industrial and agricultural sludge, livestock manure, and municipal sludge are all examples of inorganic fertilizers. Inorganic fertilizers are chemical fertilizers produced through chemical processes that contain nutrients for crop growth.
