Here is a quiz for beginners about agriculture and the science behind it. There are 17 questions having four options among which only ONE is correct. This quiz covers basic topics of agriculture. After completing this quiz, you will get a certificate of achievement.


Questions and Answers
  • 1. 

    1. Which among the following is a Kharif crop?

    • A.

      Wheat

    • B.

      Pea

    • C.

      Maize

    • D.

      Mustard

    Correct Answer
    C. Maize
    Explanation
    Maize is a Kharif crop because it is sown in the rainy season and harvested in the autumn. Kharif crops are typically grown during the monsoon season in India, which lasts from June to September. Maize requires a lot of water for its growth, making it suitable for cultivation during the rainy season. Wheat, Pea, and Mustard, on the other hand, are Rabi crops, which are sown in winter and harvested in spring.

    6. Chemical fertilizers are broadly classified into three types. 

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Chemical fertilizers are not broadly classified into three types. They are typically classified into two types: macronutrients and micronutrients. Macronutrients include nitrogen, phosphorus, and potassium, while micronutrients include elements like iron, zinc, and manganese. Therefore, the statement that chemical fertilizers are broadly classified into three types is incorrect.

    7. To solve the food problem of our country, which among the following is necessary?

    • A.

      Increased production of storage of food grains

    • B.

      Easy access of food grains to people

    • C.

      People should have money to purchase the grains

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    To solve the food problem of our country, all of the options mentioned are necessary. Increased production and storage of food grains will ensure a sufficient supply to meet the demand. Easy access to food grains for people means that they can easily obtain the necessary food. Lastly, people having money to purchase the grains is crucial as it allows them to afford the food and maintain food security. Therefore, all three factors are essential in addressing the food problem in the country.

  • 7. 

    7. Which one of the following fish is a surface feeder?

    • A.

      Rohus

    • B.

      Mrigals

    • C.

      Common carps

    • D.

      Catlas

    Correct Answer
    D. Catlas
    Explanation
    Catlas is a type of fish that is known to be a surface feeder. This means that it primarily feeds on food sources that are found near the water's surface. Unlike some other fish species, Catlas does not typically dive deep into the water to find its food. Instead, it prefers to stay near the surface and feed on insects, small crustaceans, and other organisms that are easily accessible in that area. This feeding behavior is characteristic of Catlas and sets it apart from other fish species like Rohus, Mrigals, and Common carps.

    • A.

      Two

    • B.

      Three

    • C.

      Four

    • D.

      Five

    Correct Answer
    A. Two
    Explanation
    Manures can be classified into two types based on the kind of biological material used. This means that there are only two categories or classifications of manures based on the type of biological material they are made from.

    Explanation
    Plants require 17 nutrients for their growth and development. These nutrients include macronutrients such as nitrogen, phosphorus, and potassium, as well as micronutrients like iron, zinc, and manganese. Each of these nutrients plays a crucial role in various physiological processes of plants, such as photosynthesis, root development, and overall plant health. Therefore, the correct answer is 17.

    Correct Answer
    Apiaries
    Explanation
    An apiary is a place where bees are kept and raised for the production of honey and other bee products. It is a specific location where beekeepers maintain their beehives. The term "apiaries" is used to refer to bee farms because it encompasses the entire operation of beekeeping, including the management of colonies, collection of honey, and the overall care and maintenance of bees.

    13. Using fertilizers in farming is an example of:

    • A.

      No cost production

    • B.

      Low cost production

    • C.

      High cost production

    • D.

      None of these

    Correct Answer
    C. High cost production
    Explanation
    Using fertilizers in farming is considered a high cost production method because fertilizers can be expensive to purchase and apply. Fertilizers are used to provide essential nutrients to crops, which can result in increased yields and improved quality of produce. However, the cost of fertilizers, along with the equipment and labor required for their application, can significantly impact the overall production cost for farmers. Therefore, using fertilizers in farming is an example of high cost production.

    14. Nickel is a micronutrient.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Nickel is considered a micronutrient because it is essential for the growth and development of plants. Although it is required in very small amounts, nickel plays a crucial role in various enzymatic reactions and metabolic processes in plants. It is involved in nitrogen metabolism, DNA synthesis, and the activation of certain enzymes. Therefore, even though nickel is needed in trace amounts, it is still classified as a micronutrient due to its importance in plant physiology.

    • C.

      Sulphur

    • D.

      Chlorine

    Correct Answer
    C. Sulphur
    Explanation
    The correct answer is Sulphur. The other options, Boron, Zinc, and Chlorine, are all micronutrients required in small amounts by plants for their growth and development. Sulphur, on the other hand, is a macronutrient needed in larger quantities by plants for various physiological processes such as protein synthesis and enzyme activation. Therefore, Sulphur is the odd one out among the given options.
