MY OBSERVATIONS• In the pot, I give vitamin D lentils

germinate faster than the other pot, so; Vitamin D makes germination of lentils faster.

• The cotton in the pot I give vitamin D don’t get dry fast. Maybe, with vitamin D people can breed a plant with less water.

• Lentils germinate faster than beans, so lentils germinate in less time than beans.
