Administration of Vermicompos and Potassium Nitrate Fertilizer (KNO3) to the Chemical Properties of Soil and Onion Production (Allium ascalonicum L.) in Postharvest Paddy Fields

Introduction

The use of vermicompos and potassium nitrate fertilizer (KNO3) has been gaining attention in recent years due to its potential to improve the quality of tubers and chemical properties of paddy soils after harvest. This study focuses on the administration of vermicompos and KNO3 fertilizer to improve the chemical properties of soil and onion production in postharvest paddy fields. The use of these fertilizers is expected to increase the weight of tubers and quality of onion tubers, including tubers and chemical characteristics of soil, such as pH, C-organic, N-total, and K-Tukar.

Research Background

In an effort to increase the production of shallots (Allium ascalonicum L.), it is essential to pay attention to the quality of the soil used. Good soil quality not only contributes to plant growth, but also affects the yield produced. Provision of organic fertilizer such as vermicompos, which is rich in nutrients, as well as chemical fertilizers such as potassium nitrate (KNO3), can help improve soil chemical properties. The use of vermicompos and KNO3 fertilizer can also increase the activity of soil microorganisms, which play a role in the process of decomposition and the availability of nutrients for plants.

The Importance of Soil Quality in Onion Production

Soil quality plays a crucial role in onion production. Good soil quality can lead to better plant growth, increased yields, and improved tuber quality. On the other hand, poor soil quality can result in reduced plant growth, decreased yields, and lower tuber quality. Therefore, it is essential to pay attention to the chemical properties of soil, such as pH, C-organic, N-total, and K-Tukar, to ensure optimal onion production.

Methodology

The experimental design using a random group design (shelf) aims to reduce experimental errors that may occur due to soil variation in the field. Each treatment is tested randomly in the same block, to ensure that the data obtained is accurate and reliable. The study was conducted from June to August 2019 in Medan Selayang District, Medan, with an experimental design using a random group design (RAK). In this study, two main factors were examined: Vermicompos doses consisting of 0, 10, and 20 tons/ha and KNO3 fertilizer doses consisting of 0, 100, and 200 kg/ha.

Research Result

The results showed that the application of Vermicompos and Potassium Nitrate Fertilizer (KNO3) had a significant effect on the chemical properties of the soil. Some parameters that experience striking changes include:

Soil pH: The addition of fertilizer can balance the soil pH, making it more friendly for plant growth.
C-organic: Vermicompost fertilizer increases the content of soil c-organic, which is essential for soil health.
N-Total: KNO3 fertilizer contributes to increasing total nitrogen, which is an important element for plant growth.
K-Exchange: Interaction between Vermicompos and KNO3 fertilizer is proven to increase K-Tukar, which is important for plant nutrition.

Shallot production also shows better results, with an increase in wet and dry tubers. This shows that the combination of the two fertilizers not only affects the quality of the soil, but also directly increases yields.

Additional Analysis and Explanation

Vermicompos functions as an organic fertilizer that can improve soil structure and quality. The use of vermicompos can also increase the activity of soil microorganisms, which play a role in the process of decomposition and the availability of nutrients for plants. Meanwhile, KNO3 functions as a source of potassium and nitrogen, both of which are important in supporting plant vegetative growth and tubers.

The interaction between the two types of fertilizer shows better results than if one is used separately. This shows the importance of an integrated approach in land management and fertilization, to achieve optimal agricultural output.

Conclusion

Through this research, farmers are expected to be able to take further steps in sustainable agricultural practices, by utilizing Vermicompos and KNO3 fertilizer effectively to increase the productivity of shallots and improve soil conditions in post-harvest paddy fields. This will not only help in producing better harvests but also supports the sustainability and health of the soil ecosystem as a whole.

Recommendation

Based on the results of this study, it is recommended that farmers use a combination of vermicompos and KNO3 fertilizer to improve the chemical properties of soil and increase onion production. The use of these fertilizers can also help to reduce the environmental impact of agricultural practices and promote sustainable agriculture.

Future Research

Future research can focus on the long-term effects of using vermicompos and KNO3 fertilizer on soil health and onion production. Additionally, research can be conducted to explore the potential of using other organic fertilizers and chemical fertilizers to improve soil quality and increase agricultural productivity.

Limitation

This study has some limitations, including the small sample size and the limited number of treatments used. Future research can address these limitations by increasing the sample size and using a larger number of treatments.
