B Correct answer
Explanation

ANS B - MILK PRODUCTION

This program was started by the National Dairy Development Board (NDDB) of India in 1970. Operation Flood is the program behind "the white revolution." It created a national milk grid linking producers throughout India with consumers in over 700 towns and cities, reducing seasonal and regional price variations while ensuring that the producer gets a major share of the price consumers pay, by cutting out middlemen

Which of the following helps the soil to prevent the flood?

  1. Forest

  2. Animals

  3. Fishes

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Trees help keep soil in place by holding a large amount of soil with there roots.
  • Without trees, rain runs off soil into rivers and streams, raising the water level which leads to floods.
  • Planting trees acts to shield soil from the winds, and the mulch from fallen leaves forms a layer to protect the soil on the "forest" floor.
  • Hence the forest helps the soil to prevent the flood.
  • So, the correct answer is 'Forest'.

Read the give statements and select the correct option. 
Statement 1 : Irrigation without proper drainage of water leads to waterlogging in the soil.
Statement 2 : Waterlogging draws salts to the soil surface, which are deposited as a thing crust on the land surface or start collecting at the roots of the plants.

  1. Both statements 1 and 2 are correct.

  2. Statement 1 is correct but statement 2 is incorrect.

  3. Statement 1 is incorrect but statement 2 is correct.

  4. Both statements 1 and 2 are incorrect.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Improving drainage from the inundated paddock can decrease the waterlogging period at which the crop roots are subjected to anaerobic conditions. waterlogging draws salt to the surface of the soil. The salt than is deposited as a thin crust on the land surface or starts collecting at the roots of the plants. All the statements are true.

So, the correct option is 'Both statements 1 and 2 are correct'.

Rani had an uneven plot of land in which water was scarce. What system could she adopt for irrigation?

  1. Sprinkler system

  2. Canal irrigation

  3. Fertigation

  4. Hand pump
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Sprinkler irrigation is a method of applying irrigation water which is similar to natural rainfall. Water is distributed through a system of pipes usually by pumping. It is then sprayed into the air through sprinklers so that it breaks up into small water drops which fall to the ground.
  • This system is used on uneven lands where less water is available.
  • Sprinkler system is suitable for crops such as cereals, pulses, wheat, sugarcane, groundnut, cotton, vegetables, fruits, flowers, spices and condiments and for cultivating paddy crop.
  • Hence Rani should use the sprinkler irrigation system.
  • So, the correct answer is 'Sprinkler system'.

Define irrigation.

  1. Irrigation is the watering of land to make it ready for harvesting.

  2. Irrigation is the digging of land to make it ready for agriculture.

  3. Irrigation is the watering of land to make it ready for agriculture.

  4. Irrigation is the providing of water for home needs.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Irrigation is the application of controlled amounts of water to plants at needed intervals. It is the watering of land to make it ready for agriculture. Irrigation systems are often complex combinations of canals, channels, and hoses. Irrigation helps to grow agricultural crops, landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall.

So, the correct answer is 'Irrigation is the watering of land to make it ready for agriculture'.

Method of irrigation is

  1. Surface irrigation

  2. Sprinkler irrigation

  3. Drip irrigation

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Surface irrigation is a method by which water is supplied to the soil surface by gravity. It is one of the commonest method used in agriculture. Sprinkler method is used to supply the water in the form of rain by using pipes through pumping. Watering plants by drip irrigation method is a more economical way of watering plants. In this technique, water is supplied drop by drop near the plant roots through the small opening is called as drippers. By this method, there is no loss of water due to seepage, runoff or evaporation. Thus the correct answer is option D.

What are the advantages of drip irrigation system?

  1. Water directly reaches the roots of the plants.

  2. Drip irrigation method saves 30 to 70 percent water.

  3. Cultivation in saline and alkaline soil also can be done by this method.

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • Drip irrigation method saves 30 to 70 percent water and it is possible to irrigate three times more area with the same amount of water. 
  • In this method, weeds do not spread because water reaches only near plants and does not spread in the whole field. 
  • Fertilizers and insecticides can also reach the plant directly by solution in the water and it saves 30 to 60 percent chemical fertilizers as well as 40 to 50 percent pesticides along with saving of water. 
  • Crop production is higher by 20 to 40 percent in the drip irrigation method, because plants can get air and water in required quantities, resulting in regular growth of crops. 
  • Lesser laborers are required for irrigation work. 

Therefore, the correct answer is option D.

The supply of water to crops at different intervals is____________

  1. Harvesting

  2. Winnowing

  3. Irrigation

  4. Sprinkling
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

  • The supply of water to the crops at different intervals of ti,e is called as irrigation. 
  • The time and frequency of irrigation vary from crop to crop, soil to soil and season to season. In the summer season, the frequency of watering is more due to the evaporation of water from the soil and leaves.
  • In the case of wheat, irrigation is required at intervals during different stages of plant growth. Rice crop requires standing water in the field.


Therefore, the correct answer is option C.
