Answer 1

Question:-

1) Seeds should be sown at appropriate distances and at proper depths

Answer

↬ It is necessary to sow seeds at an appropriate depth because it ensures the proper and timely germination of the seed. ... The seed sown at more depth will not be able to germinate on time and the leafs will not appear on the surface on time.

Question:-

2) Drip irrigation system is the best way to irrigate crops

Answer

↬ Drip irrigation is the most efficient and appropriate irrigation system. Instead of wetting the whole field surface, water is applied only to the plant root zone. The primary goal of drip irrigation is to apply water at the time when plants need it most and in rates needed for proper plant growth.

Question:-

3) Grains should be dried before storage

Answer

↬ Grains themselves require moisture to respire hence preventing ripening. When they are devoid of this moisture they enter a state of dormancy and can be stored for extended periods of time due to the fact that during dormancy their metabolic activity decreases.

Question:-

4) Weeds should be removed from the area of crop plants

Answer

↬ The unwanted plants that grow in the fields along with crop plants are known as weeds. They should be removed because they compete with the crop plants for space, light, minerals and nutrients, thereby increasing the competition for these crops. Presence of weeds leads to a drop in yield.

Question:-

5) Why is storage important for crops

Answer

↬ The crops have to be stored at the recommended level of moisture, which varies for different types of grains. Excess moisture in the crops promotes the growth of micro-organisms and can rot the crops and cause huge losses.

Storing: To protect the grains, they have to store in closed containers.
