Effect of Water TDS, on the Growth of Plant (Phaseolus vulgaris)

Water is the major constituent of life for the growth of animals and flora species. Water is available around the world with different Total Dissolved Solids (TDS) levels and minerals. On the basis of TDS, the hardness and softness of water are determined. (Underground water and oceanic water are found to have higher TDS than fresh water).

Aim: To understand the effect of TDS on the growth of plant.

Objectives: A study was conducted on the basis of the TDS of water to observe the effect of TDS on the growth of phaseolus vulgaris (kidney bean) plants and to check whether the water TDS is responsible for the growth of the plants or not.

Methods: Water of different TDS levels was collected from Gwalior district (Gwalior, Gwalior fresh water Takenpur, and distilled water). Water has different TDS levels ranging from 95ppm (Parts Per Million), 750ppm, 2000ppm, distilled water with 0ppm TDS, and acidic distilled water (pH 3.5–4, by adding HCl acid). The kidney beans (phaseolus vulgaris) were purchased from a local mart and sowed into the washed sand with a neutral pH of 7, and the growth was observed under sunlight. (Each pot containing 7 beans).

Results: The result of the experiment was positive as required, as the water TDS level affects the growth of plants. It has been observed that distilled water with a TDS of 0 ppm shows almost no growth, but a TDS of 750 ppm shows the maximum growth. Therefore, it has been concluded that TDS is also responsible for the growth of plants, and this practice can be done on a large scale also for the best result of growth.
