The Security of Some Sweet Potato Genotypes (Ipomoea Batatas L.) from Simalungun and Dairi in the Highlands

Sweet potatoes are one of the most widely cultivated crops in the world, and their cultivation is becoming increasingly important in the highlands of Indonesia. The highlands of Simalungun and Dairi in North Sumatra are known for their fertile soil and favorable climate, making them an ideal location for sweet potato cultivation. However, the success of sweet potato cultivation in these areas depends on the selection of the right genotype. In this study, we aim to analyze the genotype of sweet potato genotypes originating from Simalungun and Dairi in the highlands, with a focus on their morphological characteristics, growth patterns, and tuber production.

This study was conducted in the Balitsa experimental garden, located in Tongkoh Village, Berastagi District, Karo Regency, North Sumatra, at an altitude of about 1440 meters above sea level. The study was conducted for six months, starting from May to October 2018, using a non-factorial random group design method. The genotypes tested included the Thousand Dolok genotype, the Kampung Sememak genotype, the Dairi genotype, the Thousand Genotype, and the Beta-1 variety. Various parameters were observed, including the morphological character of plants, tendrils, the number of tubers per sample, tubers per sample, tuber weight per plot, and organoleptic test results.

The results of this study showed significant differences in the morphological character between various sweet potato genotypes. This variation had an impact on the growth and results of tubers, which were proven through the measurement of tendril length, the number of tubers per sample, and the weight of tubers both per sample and per plot. For example, genotypes with longer tendrils tended to have more tubers, and thus produce heavier tubers. This suggests that the selection of the right genotype is crucial for maximizing tuber production in the highlands.

Deeper analysis of environmental factors in the highlands also showed an important role in the growth of sweet potatoes. A higher altitude often affects the temperature and humidity, which can impact the process of photosynthesis and the development of roots and tubers. Therefore, the selection of exact genotypes is very important to ensure the success of sweet potato cultivation in the highlands, especially in the context of climate change that affects weather patterns.

This study not only provides insight into the genotype of sweet potato from Simalungun and Dairi, but also has the potential to be a guide for farmers and researchers in choosing the most appropriate genotypes to be planted in high areas. This can support the development of sustainable agriculture and increase food security in the area. By understanding these various characteristics, farmers are expected to maximize yields of sweet potatoes and increase their income.

Based on the results of this study, we recommend the following:

The selection of sweet potato genotypes should be based on their morphological characteristics, growth patterns, and tuber production.
Farmers and researchers should consider the environmental factors in the highlands, such as altitude, temperature, and humidity, when selecting genotypes.
Further research is needed to explore the potential of sweet potato cultivation in the highlands, including the development of new genotypes and the optimization of cultivation practices.

This study has several limitations, including:

The study was conducted in a single location, and the results may not be generalizable to other areas.
The study only focused on a limited number of genotypes, and further research is needed to explore the potential of other genotypes.
The study did not consider the economic and social impacts of sweet potato cultivation in the highlands.

Based on the results of this study, we suggest the following future directions:

Further research is needed to explore the potential of sweet potato cultivation in the highlands, including the development of new genotypes and the optimization of cultivation practices.
The development of new genotypes that are specifically adapted to the highlands of Simalungun and Dairi.
The optimization of cultivation practices, including the use of irrigation systems and fertilizers, to maximize tuber production.

In conclusion, this study provides valuable insights into the genotype of sweet potato from Simalungun and Dairi in the highlands. The results of this study suggest that the selection of the right genotype is crucial for maximizing tuber production in the highlands. We recommend the selection of sweet potato genotypes based on their morphological characteristics, growth patterns, and tuber production, and further research is needed to explore the potential of sweet potato cultivation in the highlands.
