The Effect of Giving Buffalo Manure and Dosage of Inorganic Fertilizer on Nutrients N, P, K Soil, Growth, and Production of Shallots (Allium ascalonicum L.)

Introduction

Shallots (Allium ascalonicum L.) are one of the most widely cultivated crops in the world, and their production is heavily dependent on the availability of essential nutrients in the soil. The use of fertilizers is a common practice in agriculture to improve soil fertility and promote plant growth. However, the type and dosage of fertilizers used can have a significant impact on the environment and the quality of the produce. This study aims to investigate the effect of giving buffalo manure and the dosage of inorganic fertilizer on nutrients N, P, K soil, growth, and production of shallots.

Background

Shallots are a type of vegetable that belongs to the Allium family, which also includes onions, garlic, and leeks. They are widely cultivated in many parts of the world, including Asia, Europe, and the Americas. Shallots are a good source of essential nutrients, including vitamins, minerals, and antioxidants. However, their production is heavily dependent on the availability of nutrients in the soil. The use of fertilizers is a common practice in agriculture to improve soil fertility and promote plant growth.

Methodology

This study was conducted in Unjur Village, Simanindo District, Samosir Regency, North Sumatra Province, at an altitude of about 950 meters above sea level, from January to April 2016. The study used a factorial complete random design with two factors, namely buffalo manure and inorganic fertilizer doses. The treatments used were K0 (0 tons/ha of manure), K1 (15 tons/ha of manure), and dose of inorganic fertilizer varied (P0 to P4). The study measured the length of the plant, fresh weight, and dry weight of the onion tubers, as well as the nutrients N, P, and K in the soil.

Results

The results of this study showed that buffalo manure had a significant effect on the length of the plant in the third to seventh week after planting, as well as the fresh weight and dry weight of the onion tubers. The dose of inorganic fertilizer was proven to significantly affect nutrients N and P in the soil. The results also showed that the combination of buffalo manure and inorganic fertilizer had a synergistic effect on plant growth and production.

Discussion

The use of buffalo manure as an organic fertilizer can improve soil quality and offer nutrients needed for plants. Manure not only adds nutrients, but also improves soil structure and water retention capacity. This is very important for the growth of shallots that require adequate soil moisture. In this study, manure with a dose of 15 tons/ha showed a significant increase in plant growth, seen from the length of the plant and the weight of the tubers produced.

In addition to organic fertilizer, the use of inorganic fertilizer is also essential in supporting plant growth. The right dose of inorganic fertilizer affects the availability of nutrients needed by plants. In this study, the dose of inorganic fertilizer varied from P0 to P4 showed a different effect on nutrients N and P in the soil, which contributed to the development and production of shallots.

Conclusion

This study provides valuable insight for farmers and researchers in determining the appropriate fertilization strategy to achieve maximum production of onion through soil nutrient optimization. The use of buffalo manure and inorganic fertilizer can have a synergistic effect on plant growth and production. However, the type and dosage of fertilizers used should be carefully selected to avoid any negative impact on the environment and the quality of the produce.

Recommendations

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

  • The use of buffalo manure as an organic fertilizer can improve soil quality and offer nutrients needed for plants.
  • The right dose of inorganic fertilizer affects the availability of nutrients needed by plants.
  • A good combination between the use of organic and inorganic fertilizers can optimize plant growth and improve yields, while maintaining soil health for agricultural sustainability in the future.
  • Further research is needed to investigate the long-term effects of the use of buffalo manure and inorganic fertilizer on soil fertility and plant growth.

Limitations

This study has several limitations, including:

  • The study was conducted in a single location, which may not be representative of other areas.
  • The study used a factorial complete random design, which may not be the most effective design for this type of study.
  • The study did not investigate the long-term effects of the use of buffalo manure and inorganic fertilizer on soil fertility and plant growth.

Future Research Directions

Future research should focus on investigating the long-term effects of the use of buffalo manure and inorganic fertilizer on soil fertility and plant growth. Additionally, further research is needed to investigate the effects of different types and dosages of fertilizers on plant growth and production.
