  • Question 1
    1 / -0
    Which among the following is the tool used for sowing seeds that is shaped like a funnel?
    Solution
    • The tool used traditionally for sowing seeds is shaped like a funnel. The seeds are filled into the funnel, passed down through two or three pipes having sharp ends.
    •  These ends pierce into the soil and place seeds there. 

    Therefore, the correct answer is option C.
  • Question 2
    1 / -0
    Seed drill is used for sowing with the help of ________________
    Solution
    • Nowadays the seed drill is used for sowing with the help of tractors. This tool sows the seeds uniformly at proper distances and depths. 
    • It ensures that seeds get covered by the soil after sowing. This prevents damage caused by birds. Sowing by using a seed drill saves time and labor.

    Therefore, the correct answer is option A.
  • Question 3
    1 / -0
    Which of the following statements are correct with respect to the advantages of seed drill?
    Solution
    The seed drill is mainly used for sowing the seeds. The seed drill makes holes at a proper distance in the soil and the seeds are dropped in these holes. This helps in avoiding overcrowding between plants for sunlight and nutrients. Seed drill ensures that seeds get covered by the soil after sowing. This prevents birds from picking up the seeds.
    So, the correct answer is option C.
  • Question 4
    1 / -0
    The decomposed matter is used as ___________.
    Solution
    Manure is an organic substance produced by the decomposition of plant or animal wastes in the presence of microorganisms. It is used to increase the fertility of the soil.
    Therefore, the correct answer is option B.
  • Question 5
    1 / -0
    ______ system of irrigation is more useful on uneven lands.
    Solution
    A sprinkler system is more useful on uneven lands where sufficient water is not available. In this method, water is supplied using pipes to one or more central locations within the field. When water is allowed to flow under high pressure with the help of a pump, it gets sprinkled on the crops.
    Therefore, the correct answer is option A.
  • Question 6
    1 / -0
    Which method of irrigation is cheaper but less efficient?
    Solution
    • 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.
  • Question 7
    1 / -0
    The growth of weeds can be controlled by
    Solution
    The growth of weeds can be controlled by the following methods:
    (1) Coverings: In domestic gardens, methods of weed control include covering an area of ground with a material that creates a hostile environment for weed growth, known as a weed mat. Several layers of wet newspaper prevent light from reaching plants beneath, which kills them.
    (2) Manual removal: Many gardeners still remove weeds by manually pulling them out of the ground, making sure to include the roots that would otherwise allow them to resprout.
    (3) Irrigation: Drip irrigation involves bringing water directly to the roots of the desired plants, thereby limits weed's access to water.
    (4) Biological pesticide: Vinegar kills the visible part of the weed. They will wrinkle and die the next day, although the root will still be in place to continue growing. 

    Therefore, the correct answer is option D.
  • Question 8
    1 / -0
    Which system is a boon in regions of poor availability of water?
    Solution
    Drip irrigation is an irrigation method that saves water and nutrients by allowing water to drip slowly to the roots of plants. The water is dripped slowly by a network of valves, pipes, tubes, and emitters either to the soil surface or directly to the root zone through the underground tube system. This minimizes the waste of water through evaporation.
    Therefore, the correct answer is option C.
  • Question 9
    1 / -0
    The supply of water to crops at different intervals is____________
    Solution
    • 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.
  • Question 10
    1 / -0
    Which are the different traditional methods of irrigation?
    Solution
    • 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.
