Understanding the Impact of Water pH on Deli Tobacco Plant Growth

Introduction

The growth and development of plants are influenced by various factors, including water quality and pH. Deli tobacco plants, in particular, require optimal water conditions to thrive. This study aimed to investigate the effect of water with different pH levels on the growth of Deli tobacco plants. The research was conducted at the Glasshouse of the Faculty of Agriculture, University of North Sumatra, and the Central Laboratory of the Faculty of Agriculture, University of North Sumatra.

Research Methodology

The study employed a complete non-factorial random design with four levels of application doses and five replications. The research design allowed for the examination of the effect of water pH on the growth of Deli tobacco plants. The study focused on the impact of water pH on soil chemistry and plant growth parameters, including plant height, fresh weight, dry weight, and dry weight of plant roots.

Results

The results of the study showed that the provision of water with different pH levels had a significant impact on soil chemistry and the growth of tobacco plants. The effect was observed in plant height, fresh weight of plants, dry weight of plants, and dry weight of plant roots. The study found significant differences in some soil chemical parameters, including soil pH, phosphate concentration, cation exchange capacity, and alkaline saturation.

Soil pH

The study found that the treatment with the highest pH (GU) produced a soil pH of 6.80, while the treatment with the lowest pH (GUS) produced a soil pH of 6.53. The results indicate that the pH of the water used for irrigation can affect the soil pH, which in turn can impact plant growth.

Phosphate Concentration

The highest phosphate concentration was recorded in the GU treatment with a value of 10.10, while the lowest concentration was found in the GUO treatment with a value of 7.64. The results suggest that the provision of water with the right pH can increase the availability of phosphate for plants.

Cation Exchange Capacity

The highest cation exchange capacity occurred in the GU treatment with a value of 43.77, while the lowest was found in the GU treatment with a value of 25.97. The results indicate that the pH of the water used for irrigation can affect the cation exchange capacity of the soil, which can impact plant growth.

Alkaline Saturation

The highest alkaline saturation was recorded in the GUS treatment with a value of 148.28, while the lowest was found in the GU treatment with a value of 78.93. The results suggest that the provision of water with the right pH can affect the alkaline saturation of the soil, which can impact plant growth.

Discussion

The study provides important information about the effect of water pH on the growth of Deli tobacco plants. The results show that optimal water pH can increase plant growth and the quality of the yield. This is crucial to consider in the management of tobacco plants, especially on land with different soil characteristics.

The study also highlights the impact of water pH on soil chemistry. The provision of water with the right pH can help increase the availability of nutrients for plants, such as phosphate. This is essential to consider in the tobacco plant fertilization program.

Conclusion

The study demonstrates the importance of water pH in the growth and development of Deli tobacco plants. The results provide valuable insights into the impact of water pH on soil chemistry and plant growth parameters. The study highlights the need for further research to examine the long-term effect of water with different pH on the growth and yield of Deli tobacco crops.

Recommendations

Based on the findings of the study, the following recommendations are made:

Further research should be conducted to examine the long-term effect of water with different pH on the growth and yield of Deli tobacco crops.
More detailed research should be carried out to determine the most effective optimal water pH to increase the growth and harvest of Deli tobacco plants.
