Question

Paddy is a major cereal crop in our country.

Answer 1

Hint: A paddy field is a flooded area of arable ground where semiaquatic crops like rice and taro are grown. It is related to pre-Austronesian and Hmong-Mien cultures and comes from the Neolithic rice-farming cultures of the Yangtze River valley in southern China.

Complete answer:
The following measures are done to prevent spoiling and insect attacks on harvested grains:
 i. Remove the moisture from freshly harvested crops by exposing them to sunshine.
 ii. To protect the grains from insects, dried Neem leaf extracts are sprayed on them.
 iii. Insecticides and chemicals are also used.
 iv. The godown is fumigated to get rid of the insects that have taken up residence in the gaps of the walls and floor.
 v. To remove moisture from harvested grains, they should be properly dried in the sun. To keep pests away from stored grains, sprinkle dried neem leaves on top. To keep rats and insects at bay, we can spray rodenticides or insecticides from time to time. We can avoid spoiling and insect attack of harvested grains this way.
 vi. Paddy seeds are initially grown in a nursery before being transported into the fields for sowing. This procedure aids in the selection of healthy and superior seedlings for cultivation, resulting in high-quality crops.
