15 Questions
Why is it more economical to have a shorter duration of crop maturity?
Short durations allow for multiple rounds of crops in a year and reduce production costs.
How does wider adaptability of varieties help stabilize crop production?
Different varieties can be grown under varying climatic conditions.
What is the significance of tallness and profuse branching in fodder crops according to the text?
Dwarfness is preferred for fodder crops to consume fewer nutrients.
In which type of crops is dwarfness desired according to the text?
Cereals
How do desirable agronomic characteristics contribute to higher productivity of crops?
By helping in better utilization of resources.
What is the main difference between compost and vermi-compost?
Compost is rich in nitrogen and phosphorus, while vermi-compost is rich in organic matter.
Why should fertilizers be applied carefully according to the text?
To reduce the risk of water pollution due to excess fertilizer runoff.
What is the potential consequence of continuous fertilizer use in an area?
Destruction of soil fertility as organic matter is not replenished.
How does organic farming differ from conventional farming practices as described in the text?
Organic farming minimizes chemical inputs and maximizes organic manures.
Why should the short-term benefits of using fertilizers be balanced against long-term considerations according to the text?
To maintain soil fertility over time and avoid negative impacts of continuous use.
Which agricultural practice involves the use of earthworms to hasten the decomposition process of plant and animal refuse?
