= Wrong statement.
= Correct statement : There are numerous methods of farming.
(b) India is an agricultural country.
= Correct statement.
= India is an agrarian country.
(c) Use of improved seeds does not lead to higher yields.
= Wrong statement
= Correct statement : Use of improved seeds can induce higher-yields.
Question no – (4)
Answer :
(a) Advantages of using improved seeds :
Use of improved seeds usually have a higher yielding capacity. The improved seeds can also withstand the pests and insects attacks. There are some varieties which get’s ripened for harvesting in a limited time period while there are some seeds which leads to a higher yield even with a minimum water supply.
(b) Modern methods of irrigation and its advantages :
The modern method of irrigation are drip irrigation and sprinkle irrigation. The roots of the crops can get sufficient amount of water due to the modern technique of irrigation. An ample amount of water can be saved by using these techniques. The available water can be used to it’s fullest by using these modern techniques of irrigation. When there is excessive watering, there are high risk of land becoming saline and dormant.
(c) Drip irrigation :
Drip irrigation is also known as trickle irrigation and involves saving water and fertilizer by letting the water to drip slowly towards the surface of the soil or straightly towards the root zone, by using pipes, valves and emitters. This assures that the amount of water needed sprinkles only near the plants. Therefore, the available water is used to it’s fullest.
(d) Reasons for crop damage :
There can be pests or insects attack on the growing crops, as a result of which the growing crops can be damaged. The productivity of fields can be lessened, if soil fertility is reduced. The growth of the crops can be impeded, if there is insufficient availability of water for the growing crops.
(e) Modern irrigation techniques are used for watering the crops, in order to avoid the damage to crops. The crops are sprayed with pesticides and insecticides, in order to lessen the attacks of pests and insects. Before sowing, the improved quality seeds are rubbed with certain chemicals. In order to amplify the growth of the crops, appropriate quantity of fertilizers are used.
(f) When chemical fertilizers are used to an extreme amount, it brings about an excessive accumulation of chemicals in the soil. This lessens the soil fertility and lowers the productivity of the soil. Excessive amount of watering can lead to danger of land becoming saline and unproductive.
(g) Improved quality of seeds are used by modern technique of agriculture that leads to higher yield. Drip irrigation and sprinkle irrigation are the modern technique of irrigation that are used. In order to enhance the fertility and productivity of soil, organic fertilizer and manures are used. In order to protect the crops from pests and insects attacks, pesticides and insecticides are used. The agricultural assistance programmes have provided the farmers with the required information and updates about weather forecasts, which have ultimately helped in bringing about a greater yield in the farm production.
(h) The food grains are dried thoroughly in the sunlight and are stored in containers. In order to avoid pests and insects attack, neem leaves are mixed with the food grains. Neem leaves acts as a pesticide during the time of storage. In order to store food grains, dried neem leaves are used because they soak moisture content from the grains. Chemicals are sprinkled on those places where the containers are stored. The grains are stored in cool and dry places. In such storage place, the chances of fungus infestations are quite less.
(i) India is an agricultural country. So, most of the agriculture in India is dependent upon the monsoon season. In addition with this rain water, water from rivers, lakes and wells are used for the purpose of irrigation. In order to hold back huge quantities of water, dams are constructed across the rivers. Reservoirs that are created by dams are not only designed to repress flood but also to provide water for human consumption, irrigational purposes, commercial uses and aqua farming. On a traditional basis, mot and canal water was used to water the crops. Nowadays, modern technique of irrigation are used for the purpose of farming
Question no – (5)
Answer :
(1) → (c) Fungus attack to the stored grain.
