The Effect of Addition of Urea Fertilizer on Nitrite Content to Spinach Plants (Amarantus Tricolor) After Cooking for Five Minutes

Introduction

The consumption of vegetables is essential for maintaining a healthy diet, but the nitrite content in these vegetables can have a significant impact on human health. Spinach, a popular leafy green vegetable, is one of the most commonly consumed vegetables worldwide. However, the nitrite content in spinach can be a concern, especially when it is cooked for a short period of time. This study aims to analyze the effect of the addition of urea fertilizer on nitrite content in spinach plants (Amarantus tricolor) after being cooked for five minutes.

Background

Nitrite is a compound that can be found in vegetables, and it can be produced through the metabolic process of plants. However, excessive nitrite consumption can cause health problems, such as methhemoglobinemia, a condition where the blood's ability to transport oxygen is impaired. Therefore, it is essential to understand the factors that affect nitrite levels in vegetables, including the use of fertilizers.

Urea fertilizer is a common nitrogen-based fertilizer used in agricultural cultivation. It is a source of nitrogen, which is essential for plant growth and development. However, excessive use of urea fertilizer can lead to the accumulation of nitrates in plants, which can then turn into nitrite in the metabolic process. This study aims to investigate the effect of urea fertilizer on nitrite content in spinach plants after being cooked for five minutes.

Methodology

The study used a colorimetric method with the diazotization method to measure the nitrite levels in spinach plants. This method involves the use of spectrophotometric equipment to produce a reddish-purple color that can be analyzed further. The beer-lambert law was used to measure the absorbance of light at a wavelength of 540 nm to determine the level of nitrite.

The study used six different variations of urea fertilizer, ranging from 0 to 500 grams per two square meters. The spinach plants were grown in a controlled environment, and the nitrite levels were measured after being cooked for five minutes. The results showed that the addition of urea fertilizer with variations of 0, 100, 200, 300, 400, and 500 grams per two square meters provided different nitrite levels.

Results

The results of the study showed that the nitrite levels in spinach plants increased with the addition of urea fertilizer. The data obtained showed the following nitrite levels: 1,004; 1,103; 1,331; 1,460; 1,495; and 1,502 mg/ml. These results indicate that the more urea fertilizer added, the higher the level of nitrite in spinach plants.

Discussion

The increase in nitrite levels may be caused by several factors, including the accumulation of nitrates in plants due to excessive use of urea fertilizer. Nitrite itself is a compound that can be dangerous for health, as it can interact with hemoglobin and interfere with the ability of blood to transport oxygen. Therefore, it is essential to control the use of nitrogen fertilizer, especially in vegetable cultivation that is consumed directly.

The results of this study recommend that farmers and vegetable producers pay attention to the dose of fertilizer used. The use of urea fertilizer must be done wisely, given the impact that may be caused not only for plants but also for consumer health. In addition, vegetable cooking methods, such as spinach cooking for five minutes, can also affect nitrite levels. Further research can be done to understand the effect of how to cook and fertilizer dosage on nitrite content more deeply.

Conclusion

In conclusion, this study has shown that the addition of urea fertilizer can increase the nitrite content in spinach plants after being cooked for five minutes. The results of this study recommend that farmers and vegetable producers pay attention to the dose of fertilizer used and control the use of nitrogen fertilizer to avoid excessive nitrite levels in vegetables. Further research can be done to understand the effect of how to cook and fertilizer dosage on nitrite content more deeply.

Recommendations

Based on the results of this study, the following recommendations are made:

  1. Farmers and vegetable producers should pay attention to the dose of fertilizer used to avoid excessive nitrite levels in vegetables.
  2. The use of urea fertilizer must be done wisely, given the impact that may be caused not only for plants but also for consumer health.
  3. Vegetable cooking methods, such as spinach cooking for five minutes, can also affect nitrite levels. Further research can be done to understand the effect of how to cook and fertilizer dosage on nitrite content more deeply.

Future Research Directions

Further research can be done to understand the effect of how to cook and fertilizer dosage on nitrite content more deeply. Some possible research directions include:

  1. Investigating the effect of different cooking methods on nitrite levels in vegetables.
  2. Studying the effect of different fertilizer dosages on nitrite levels in vegetables.
  3. Investigating the effect of other factors, such as soil type and climate, on nitrite levels in vegetables.

By understanding the factors that affect nitrite levels in vegetables, we can be more careful in the practice of agricultural cultivation and improve the quality of food that is safer and healthier.
