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.

• 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'.

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.

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.

• 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. 

• The supply of water to the crops at different intervals is called irrigation. Lakes, rivers, dams, canals, etc. are the sources of water for irrigation. 
• The water from lakes or canals is lifted up by different methods. Human or cattle labor can be used for these methods. 
• Various traditional ways of irrigation are pulley system, chain pump, dhekli, and Rahat. 
• Traditional methods are cheaper but they are less efficient as compared to modern methods like a sprinkler system, drip system, etc.

• 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.

• Irrigation systems are also used for dust suppression, disposal of sewage, and in mining. Irrigation is often studied together with drainage, which is the natural or artificial removal of surface and subsurface water from a given area.
