Tomato is one of the products with the highest production and consumption in the world, and it is among the sine quanon of human nutrition because of its high trade. In terms of plant yield, water deficiency is an important factor. In addition, salt stress in plants is an important limiting environmental factor affecting production. During the study period, the temperature values of the growing room were kept at 23 / 17 ±2 °C (day/night), 55–60% humidity, and under 8000 lux light intensity. In practice, irrigations of 25%, 50%, 75%, 100%, 125%, 150%, 175%, 200%, salt 50 mM, salt 100 mM, and salt 150 mM were performed. It was determined that the control plants under drought and salt stress gave poor and negative results in terms of plant growth. In our application, it was determined that tomato plants under drought, salt, and water stress (excessive water level) had a higher chlorophyll content than plants not exposed to drought. It was observed that the potassium ratio (%) of the tomato plant in the green and root parts of the tomato plant was higher in the control plants exposed to salt stress. It was determined that the potassium ratio (%) in the green and root parts of the tomato plant accumulated more in the control plants at irrigation levels of 100%, 125%, and 150%. In the study, it was determined that water and salt stress applications affect the growth and development of plants negatively, as seen in plants under stress (salt stress, water deficiency and excess). In addition, water plays a vital role for plants in the world.
