ABSTRACT This experiment was designed to evaluate the effects of salt water on plant growth. Six corn plants were planted each in their own cup, 1½ inches in soil. Three plants represented the control group and were watered twice a week with 20mL of RO water; the other three plants represented the experimental group and were watered twice a week with 20mL of 10% salt water solution. The growth of each group was recorded twice a week in centimeters using a ruler. After four weeks of observation the results of the experiment concluded that salt water did have an effect on plant growth. Overall the experimental group as a whole grew less than the control group. The experiential group actually reached a peak where they stopped growing and started to wilt and die. Based on these observations it was concluded that watering plants with salt water is detrimental to their growth. INTRODUCTION The objective of this experiment was to determine if saltwater would affect the growth of corn. Research showed water moves from the soil and up the roots from a higher water concentration gradient to a lower one. Salt added can lower the water potential in the soil by
