Analysis of Physiological Character of Two Varieties of Shallots on Various Watering Frequencies

Shallots are a type of vegetable that belongs to the Allium family, which also includes onions, garlic, and leeks. They are widely cultivated and consumed in many parts of the world, particularly in Asia and Europe. Shallots are known for their unique flavor and aroma, which are often used in cooking and as a flavor enhancer. However, shallots are also sensitive to environmental conditions, such as water availability, which can affect their growth and productivity.

Understanding the Physiological Response of Shallots to Watering Frequencies

Watering is a critical aspect of shallot cultivation, as it can impact the plant's growth, productivity, and overall health. Shallots have a different response to water shortages, and this response can be observed through various aspects such as physiology, morphology, growth rates, and productivity. This study aims to analyze the physiological characters of two shallots varieties at different watering frequencies, with the goal of providing valuable insights for farmers and researchers.

Research Methodology

This study was conducted on the experimental land of the Faculty of Agriculture, University of North Sumatra from May to September 2019, using a random group design (RAK) consisting of two factors. The observations of physiological characteristics were carried out in 42 days after planting, and some of the parameters observed include the relative water content of leaves, chlorophyll levels A and B, total chlorophyll, hydrogen peroxide levels, and enzyme activity such as superoxide dismutase, dismutase peroxide, and peroxidase ascorbate. This measurement aims to evaluate how the two varieties of shallots react to different watering frequencies, especially watering every 5 days and other intervals.

The Importance of Chlorophyll in Shallot Plants

Chlorophyll is a green pigment found in plants that plays a crucial role in photosynthesis, the process by which plants convert light energy into chemical energy. Chlorophyll levels A and B, as well as total chlorophyll, were observed in this study to determine the ability of shallot plants to carry out photosynthesis efficiently. The results showed that the varieties of Bima Brebes shallots were able to produce the highest levels of chlorophyll B and total chlorophyll among the varieties tested. This discovery reflects the ability of this variety to carry out photosynthesis efficiently, which is very important for plant growth and development.

The Role of Watering Frequencies in Reducing Oxidative Stress

Hydrogen peroxide is a compound that can cause oxidative stress in plants, leading to damage to cellular components and ultimately affecting plant growth and productivity. The results of this study showed that watering every 5 days gives profitable results, by producing the lowest levels of hydrogen peroxide. This shows that regular watering can help reduce oxidative stress in plants, which is essential for maintaining plant health and productivity.

The Importance of Enzyme Activity in Shallot Plants

Enzymes play a crucial role in plant metabolism, and their activity can be affected by environmental conditions such as watering frequencies. The results of this study showed that watering every 5 days is associated with the highest activity of the peroxidase ascorbate enzyme. This enzyme plays an important role in the defense mechanism of plants against stress, including lack of water. High enzyme activity shows that plants are not only able to survive, but also adapt to less supportive environmental conditions.

The Interaction between Field Varieties and Watering Frequencies

The interaction between the field varieties and watering frequencies was also observed in this study. The results showed that the peroxidase ascorbate enzyme is also seen appearing significantly in the interaction between the field varieties and watering frequencies. This indicates that although Bima Brebes varieties show superior results, Medan varieties also have the potential to develop well under proper watering.

Conclusion

Overall, this research provides valuable insight into the physiological response of shallots to watering frequencies. This finding is very beneficial for farmers and researchers in choosing the right varieties and determining effective watering strategies to improve the yield of shallots. By understanding the physiological characters of these two varieties, we can optimize the cultivation of shallots in various climate and watering conditions.
