Important Topics for Class 9 Science Chapter 15 Improvement in Food Resources

Food is an essential resource significant for all living beings. It provides nutrients like carbohydrates, vitamins, protiens and minerals. There are various sources of food such as agriculture and animal husbandry.

Artificial Hybridisation

Artificial hybridization is expressed as a method of usage of selective pollen grains to further hold pollination and fertilization. It comprises crossing of several genera and species in order to achieve a specific product.

In order to bring artificial hybridization in effect, these two steps are followed:

Emasculation
Bagging

Nutrient Management

Nutrient management is a procedure that assists in controlling the amount, source, and timing of nutrient application in order to minimize nutrient losses and simultaneously escalate agricultural output.

Example: State the importance of Nutrient Management.

Solution: The importance of Nutrient Management is:

Plant nutrients can potentially pollute waterways. This is where nutrient management assists the process of minimizing damage.
Nutreint Management actively elevates plant productivity.
It also boosts soil fertility.
Nutrient Management helps promote carbon sequestration, simultaneously preventing the degradation of soil, ecosystem, and overall loss of nutrients from the soil.
