Answer:

The process of utilising industrial sewage for growing certain plants is known as sewage farming. Sewage is particularly rich in nitrogen and phosphorous, which are required by plants for growth.

Answer:

Wheat is a rabi crop, i.e., it requires cold conditions to grow. If it is sown in the kharif season, the seeds will not germinate due to the excessive heat and dry weather.

Page No 19:

Answer:

Farmers grow different crops in a field because it helps them to replenish the nutrients in the soil naturally. It also reduces the cost of adding fertilisers. Crops are selected in such a manner that the products and waste material of one kind of crop help in the growth of another kind of crop.

Page No 19:

Answer:

Paddy is a kharif crop, i.e., it needs high temperature and dry weather for its growth. Hence, it cannot be grown during winters as its seeds will not germinate at low temperature.

Page No 19:

Answer:

Ploughing the field can only be done in the dry season because during dry seasons the soil is tight and it can be broken down easily. This helps in proper aeration of the soil. While ploughing, fresh soil nutrients emerge to the surface, thus preparing it for cultivation of crops.

Answer:

Drip irrigation is adopted in areas of acute water scarcity because it reduces the wastage of water. In this method, water is made to fall directly at the roots of plants, drop by drop.

Answer:

Weeds are unwanted plants that grow in crop fields and compete with crops for space, nutrients, light and water. Dalapon is a weedicide.

Page No 20:

Answer:

Weeding is done before harvesting; it prevents weeds from growing in the crop fields. Harvesting is the last step in the cultivation of crop plants and is carried out after the crop has matured.

Answer:

Baisakhi and Pongal are two harvest festivals of India.

Page No 20:

Answer:

The land is levelled before sowing because levelling the land breaks big soil crumbs into smaller pieces. This process also protects the fertile upper layer of the soil from erosion. It prepares the soil for the germination and growth of crops by making it a little compact.

Page No 20:

Answer:

Transplantation is a practice used for cultivation of those crops whose seeds cannot be sown directly in the field. In this method, seeds are first planted in nurseries where they germinate into small plantlets or seedlings. These plantlets or seedlings are later transferred to the main field when they have attained enough maturity. Rice, tomato, onion, brinjal and chilli are grown by this method.

Page No 20:

Answer:

In mixed cropping, two or more crops are grown together in the same field. Crops are selected in such a manner that one crop should be able to fulfil the nutrient requirement of the other crop. Therefore, fertilisers are not needed or their requirement is reduced which helps in replenishing the soil fertility as very little chemicals are added to the soil.

Page No 20:

Answer:

Kharif crops Rabi crops
They are sown at the beginning of the south west monsoon, i.e. during June or July. They are sown at the beginning of winter, i.e. from October to December.
They are harvested in September or October after the monsoon season. They are harvested in March or April.
Examples: rice, maize Examples: wheat, pea

Answer:

Manure is an organic substance which is obtained by the decomposition of dead animals and plants and their waste. The main purpose of adding manure to the soil is to make it more fertile by providing nutrients and organic matter to it.

Page No 20:

Answer:

Seeds are treated before sowing because it helps in preventing seed-borne diseases in plants. Seeds are usually treated with fungicides to destroy fungi.

Page No 20:

Answer:

Crops could be protected from pests and diseases by spraying pesticides. These are the chemicals that are sprayed over the crop plants to destroy insects, fungi, viruses and rodents.

Answer:

The following are two functions of soil:

(a) It helps in agriculture.
(b) It helps in the growth of forests and thereby provides appropriate conditions for the growth and survival of various life forms.

Answer:

Animal husbandry is a branch of agriculture that deals with the breeding, feeding and caring of domestic animals for food and other useful purposes. It is different from domestication as in the latter case, animals are not kept for obtaining food from them but for our protection or companionship.

Answer:

A farmer has to adopt the following agricultural practices for growing wheat crops:

(a) Preparation of soil: It involves three steps, i.e. ploughing, levelling and manuring.
(b) Sowing
(c) Applying manure and fertilisers
(d) Irrigation of the crop field
(e) Weeding
(f) Spraying the crop with pesticides

Answer:

Manure Fertiliser
It is a natural substance obtained by the decomposition of animal waste and plant residue. It is a man-made substance, which is generally an inorganic salt or an organic compound.
It has a comparatively low nutrient content. It has a higher nutrient content.
It is rich in organic matter and adds humus to the soil. It is rich in inorganic matter and does not add humus to the soil.
It is not soluble in water. Therefore, it  is absorbed slowly by plants. It is soluble in water and is readily absorbed by plants.
It is cheaper. It is expensive.

Page No 21:

Answer:

The unwanted plants that grow along with the crops are called weeds. These plants decrease the crop yield as they compete with crops for water, nutrients and sunlight and limit their growth. Weeding is done by the following methods:

(a)  Manual method: Weeds are pulled out by hand or are uprooted by using a trowel or a harrow.
(b) Biological method: Insects that feed upon specific weeds are used to control these weeds.
(c) Using weedicides: Certain chemicals that kill the weeds without harming the crop are called weedicides. These are diluted in water and sprayed in the field.
Two examples of weeds are wild oats and amaranthus.
Two examples of weedicides are Dalapon and Metachlor.

Answer:

Irrigation is the process of supplying water to the crop plants using canals, wells, reservoirs, tube wells etc. The following are the four main types of irrigation systems in India:

(b) Basin irrigation: In this method, a field is filled with water.
(c) Sprinkler irrigation: Water is sprinkled by sprinklers in the field.
(d) Drip irrigation: Overhead pipes are used that provide water directly at the roots of the plants, drop by drop.
