01: Elements of sustainable agriculture are as follows:

  • Mixed farming.
  • Permaculture.
  • Crop rotation.
  • Multiple cropping.

02: Objectives of sustainable agriculture are as follows:

  • Healthy environment
  • Economic profitability.
  • Social and economic equity.

03: Minimum tillage

  • Origin: United States of America
  • Minimum tillage is aimed at reducing tillage to the minimum.
  • Seed germination is lower.

04: The renewable sources of energy are as follows:

  • Wind power.
  • Solar power.
  • Water energy.
  • Geothermal energy.

05: The non-renewable sources of energy are as follows:

  • Coal.
  • Petrolium.
  • Forest.

06: The full form of CEA is controlled environment agriculture.

09: Because all are prohibited in organic farming.

10: In organic farming, soil and not the crop are fed.


11: Organic farming avoids the direct use of readily soluble chemicals such Muriate of potash. Basic slag is insoluble in water. It is not readily soluble chemical.

12: The three basic principles of organic agriculture are as follows:

  • Ecologically sound.
  • Economically feasible.
  • Socially acceptable.

13: The best method of detoxification and disposal of non-metallic toxicants:

  • Physical.

14: Examples of biorational pesticides asr as follows:

23: Types of erosion

  • Splash erosion: removal of soil particles due to rain drops.
  • Rill erosion: chanalization begins.
  • Ravines: The advanced stage of gully erosion.

24: Different measures

  • Agronomical measures: land slope is <2%. Mechanical measures: land slope is >2%.
  • Contour bunding: land slope is 6%.
  • Bench terracing: land slope is 16-33%.

25: The efficiency of drip irrigation is as high as 90%.

26: Due to mixed farming, a farmer can bear the failure of one specific crop.

27: In relay cropping, second crop is taken just after the harvest of first crop. Example is paddy and lathyrus.

  • Paddy crop is harvested.
  • No ploughing is necessary.
  • Available moisture is used for the second crop.
