Questions and Answers

Why is it more economical to have a shorter duration of crop maturity?

  • Shorter crop durations consume more nutrients leading to higher productivity.
  • Short durations allow for multiple rounds of crops in a year and reduce production costs. (correct)
  • Short durations lead to higher crop losses during harvesting.
  • Tallness and profuse branching are characteristics desired for shorter crop durations.

    • How does wider adaptability of varieties help stabilize crop production?

  • Different varieties can be grown under varying climatic conditions. (correct)
  • All varieties are suited for the same environmental conditions.
  • Stabilized crop production results in longer crop maturity periods.
  • Wider adaptability leads to less uniform maturity in crops.

    • What is the significance of tallness and profuse branching in fodder crops according to the text?

  • Developing varieties with short heights is desirable for fodder crops.
  • Tallness and profuse branching lead to faster maturity of fodder crops.
  • Dwarfness is preferred for fodder crops to consume fewer nutrients. (correct)
  • Tallness and profuse branching reduce the cost of crop production for fodder crops.
