Theory:

Modern agricultural practices are carried out to improve plant cultivation
It comprises soil preparation, sowing, manure and fertiliser application, proper irrigation, protection from weed and pests, harvesting, threshing, and storage.
 
Crop improvement aims to improve crop varieties with higher yields, better quality, disease resistance, and shorter maturation times.
Green Revolution:
Traditional farming practices can yield only limited food for humans and animals, but we use improved management practices to increase production, and it has certain limitations. Plant breeding, thus, increased the yield of crops. The green revolution was satisfying the food demands and helped in the export of food.
The Green Revolution is the process of improving food production in underdeveloped and developing countries by using high-yielding crop varieties using modern agricultural techniques.

In \(1970\), Dr Norman E. Borlaug, an American agronomist regarded as the "Father of the Green Revolution," was awarded the Nobel Peace Prize. Dr M. S. Swaminathan and Dr Borlaug collaborated in bringing the Green Revolution to India by introducing Mexican wheat strains.
 
Green revolution depended on the plant breeding techniques for high yielding and disease-resistant varieties in wheat, rice, maize etc. Between the years \(1960\) and \(2000\), this resulted in increased wheat and rice production.
 
Dr Mankombu Sambasivan Swaminathan is a well-known Indian scientist who played a crucial role in India's Green Revolution. His plant breeding experiments on potatoes, wheat, rice, and jute are well-known. Wheat production improved from twelve million tonnes in the \(1960\)s to seventy million tonnes now due to his efforts. He is known as the "Father of the Indian Green Revolution".
