Explain the changes that have been occurred rapidly in the diversification of crop rotation after Green Revolution.
Answers
"Crop rotation is the pattern and practice of cultivating different crops on the same land and area, followed by one after the other depending on the suitable season for maximum output, with a sustainable development and retaining of the productivity capacity of land appropriately and avoiding soil erosion. Green revolution was a reform and a remarkable revolution in the field of agriculture that evidently and efficiently worked on increasing the productivity of the land with the use of high-yield-variety crops and seeds, fertilisers, pesticides. It also lead to better technological advancements, new methods, and techniques of cultivation, aiding any lack that reduced the capacity.
Green revolution brought in a replacement of traditional methods of agriculture. With high yielding variety of crops, better immunisation, technical implements crop rotation became more efficient where different crops were able to sustain its natural hurdles and enemies in terms of pests, insects, and rodents and gave a better productivity.
As HYVs grow and mature faster, it was easy to grow a 2nd or 3rd crop in rotation in a year. However, on a longer pace, for the reason of commercialisation and want of maximum profit, it has led to decrease in genetic diversification and variety and the practice of mixture of rotation was replaced by single cultivation of crops like wheat and rice only for procuring maximum profits and depleting the soil fertility due to the use of fertilizers, pesticides, and dwarf crops that left no straws or remains to naturally replenish the organic matter of the soil."
