Open Field Agriculture Faces Different Kinds Of Risks .
1. Climate change risks .
Associated by low or high temperatures,Low or high rainfall, high wind ,high relative humidity and lightning.
2. Biotic risks . incidence of pests , diseases and weeds
3. Market risks . Increase in the cost of cultivation and variation in prices of crops
What is the way forward????
According to the Modern Portfolio theory,the probability of risks is maximum ( 100%) in monoculture one- crop agriculture),50% in two crops intercropping system and lowest in mixed cropping of 20 crops or polyculture.
Polyculture remains one of the ways in mitigating risks in open Field Agriculture .
