Question

What are the factors for which a variety of improvement of the crop is done?

Answer 1

Hint: Crops need to be improved genetically for the better production and food quality. It can be done by techniques such as gene editing and genetic engineering and also, traditional methods should be followed.

Complete answer: The factors that help to improve crop variety are as follows:
a) Higher yielding capacity: Increase the crop production per unit area of the crop field to obtain higher yield.
b) Improvement of quality: The crops have increased amounts of nutrients like proteins, minerals like zinc, calcium etc.
c) Resistance to biotic and abiotic stress: Insects, pests, dry environments can cause stress to the crops, so it has to be controlled to improve the variety of crops.
d) Change in the duration of maturation: Some crops need more time to mature. If the crops are improved genetically, it will take less time to mature which increases production.
e) Wide adaptability: Some crops are cultivated in some particular atmosphere. So, crops need to be improved, so that it can be cultivated in other environments as well.
f) Desirable agronomic characteristics: Some fodder crops need to be tall for profuse branching, whereas dwarfness is the agronomic characteristic of cereal crops.

Note: The crop rotation method is the best way to increase soil fertility. This is because different crops need different nutrients from the soil and contribute to different types of nutrients and minerals in the soil. So, if we perform the crop rotation method then the soil will be rich in all the nutrients and minerals and the fertility of the soil will be increased.
