Introduction

Potato (Solanum tuberosum L.) is one of the most widely cultivated crops globally, providing a significant source of food and income for millions of people. However, the process of breaking dormancy in potato seeds is a critical step in potato cultivation, as it directly affects the growth and yield of the crop. Dormancy is a natural process that occurs in seeds, where they remain in a state of inactivity until the right conditions for germination are met. Breaking dormancy is essential to initiate seed germination and subsequent plant growth.

This study aims to investigate the effect of tuber weight and cytokinin immersion treatment time on the breaking of dormancy in potato seeds. Cytokinin is a plant hormone that plays a crucial role in plant growth and development, including seed germination and dormancy breaking. The research activity was conducted at the UPT Horticultural Seeds in Kutagadung, Berastagi, under the auspices of the Food and Horticultural Crops Office, North Sumatra.

Methodology

The method used in this study is a factorial complete random design (RAL) with two factors that are the main focus. The first factor is the weight of potato seeds, consisting of four levels: B1 (25-35 g), B2 (55-65 g), B3 (85-95 g), and B4 (115-125 g). The second factor is the time of immersion of cytokinin, which has five treatments: W0 (control), W1 (1 day after harvest), W2 (15 days after harvest), W3 (30 days after harvest), and W4 (45 days after harvest).

Results

The results of this study showed that the fastest breaking of dormancy occurs in seeds with a weight of 115-125 g, with a time of 60.67 days, which is faster 14.06 days compared to the weight of 25-35 g. In addition, the breaking of dormancy is also influenced by the time of immersion of cytokinin. Soaking at 45 days after the harvest produces the fastest dormancy breeding time, which is 62.08 days. This treatment is 11.75 days faster than control, and faster 5.25 days than soaking treatment for 1 day.

Discussion

The combination of tubers 115-125 g and the immersion time of 45 HSP (days after harvest) gives the best results in the breaking of dormancy, with a time of 55 days. This study not only provides insight into the technique of breaking dormancy, but also shows how the physical characteristics of seeds can affect agricultural products. Increased number and weight of buds along with the increase in tuber weight and immersion time also show the potential to increase yields.

Conclusion

The importance of this research lies in its practical application in potato cultivation. Farmers can utilize information about the weight and time of immersion to increase the efficiency of dormancy breaking, which in turn can produce better growth and optimal crops. In this way, this research makes a positive contribution to the agricultural sector, especially in the production of quality potato seeds.

Recommendations

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

  • Potato farmers should consider using seeds with a weight of 115-125 g for better dormancy breaking.
  • Cytokinin immersion treatment at 45 days after harvest can be used to accelerate the breaking of dormancy.
  • Further research is needed to investigate the effect of other factors, such as temperature and humidity, on the breaking of dormancy in potato seeds.

Limitations

This study has some limitations that should be considered when interpreting the results. Firstly, the study was conducted in a controlled environment, and the results may not be applicable to field conditions. Secondly, the study only investigated the effect of two factors, tuber weight and cytokinin immersion treatment time, on the breaking of dormancy. Further research is needed to investigate the effect of other factors on the breaking of dormancy.

Future Research Directions

Future research should focus on investigating the effect of other factors, such as temperature and humidity, on the breaking of dormancy in potato seeds. Additionally, the study should be replicated in different environments to validate the results. Furthermore, the study should investigate the effect of other cytokinin concentrations and treatment times on the breaking of dormancy.

Conclusion

In conclusion, this study provides valuable insights into the effect of tuber weight and cytokinin immersion treatment time on the breaking of dormancy in potato seeds. The results of this study can be used by potato farmers to improve the efficiency of dormancy breaking and increase crop yields. Further research is needed to investigate the effect of other factors on the breaking of dormancy and to validate the results of this study.
