Explanation:
Seed selection is very important in order to get a good crop. Good seeds, produces good and healthy crop.
In irrigation process, plants get water from regular intervals for agriculture.
In extreme cold weather the water in the plants get freeze which eventually leads to the expansion of water causing the dead cells and the plant will become brown or even dead. However, in extreme hot weather, plants try to close their air holes to save water from evaporation, when plants fail to do so, the scarcity of water takes place inside the plant and they dies because of dehydration.
Some farmers prefers manures to fertilize the soil other use chemical fertilizers depending upon their crop or soil demand. However, artificial fertilizers can never be a replacement of natural fertilizers.
