Sweet Potato Genotype Responses (Ipomoea Batatas L.) and the Form of Beds to Growth and Production

Introduction

Sweet potatoes (Ipomoea batatas L.) are one of the most widely cultivated root crops in the world, providing a vital source of nutrition and income for millions of people. However, the growth and production of sweet potatoes can be influenced by various factors, including genotype and cultivation practices. This study aims to investigate the effect of sweet potato genotypes and the form of beds on plant growth and production, with the ultimate goal of developing more effective cultivation strategies for farmers in the Tanjung Anom community, Medan Tuntung, North Sumatra, Indonesia.

Study Location and Design

The study was conducted on the land of the Tanjung Anom community, Medan Tuntung, North Sumatra, Indonesia, which is located at an altitude of ± 25 meters above sea level. The study took place from June to October 2018, using a Randomized Group Design (RAK) consisting of two treatment factors: Purple Sweet Potato Genotype from several different locations and forms of beds. The genotype used in this study included: Purple Semalungun Silimakuta Purple Sweet Potato from Bintang Mariah Hamlet, Purple Sweet Potato Simalungun Dolok Pardamean Sirube-Rube, Dairi Parbulu Parbulu Purbuluan sweet potato from Simallopuk Village, and Purple Sumbul Sumbul Tanjung Beringin. Meanwhile, the form of beds tested is: one beds for one plant, one bed for two plants, and one beds for three plants.

Observed Parameters

In this study, several parameters were observed to evaluate the growth and production of sweet potatoes, namely:

Plant Tendrils Length: The length of the plant tendrils was measured to assess the growth and development of the plants.
Number of Tubers per Sample: The number of tubers produced per sample was counted to evaluate the yield of the plants.
Length of Tubers per Sample: The length of the tubers produced per sample was measured to assess the quality of the tubers.
The Diameter of the Tuber per Sample: The diameter of the tubers produced per sample was measured to evaluate the size and quality of the tubers.
The Weight of the Tubers per Sample: The weight of the tubers produced per sample was measured to assess the yield and quality of the tubers.
The Weight of the Tubers per Plot: The weight of the tubers produced per plot was measured to evaluate the yield and quality of the tubers at the plot level.
Organoleptic Test on Tubers: The tubers were subjected to an organoleptic test to evaluate their quality and acceptability.

Results and Discussion

The results of this study showed that sweet potato genotype had a significant effect on plant tendrils, the number of tubers per sample, and the diameter of the tubers per sample. This indicates that the selection of appropriate genotypes can increase the growth and production of sweet tubers. On the other hand, the form of beds applied also has a significant effect on the weight of tubers per plot, which shows that planting techniques with appropriate arrangements can contribute to optimal crop yields.

However, the interaction between the genotype and the form of beds does not show a significant effect. This means that although these two factors can have an impact on growth and production, the combination of the two does not produce better effects than the influence of each factor separately.

Conclusion

From the results of this study, it can be concluded that the selection of appropriate sweet potato genotypes and the application of the right form of beds is very important in increasing plant growth and production. This study provides valuable insights for farmers and researchers to develop more effective cultivation strategies, so it is expected to increase the production of sweet potatoes in the Tanjung Anom and surrounding areas. This is not only useful to meet local needs, but also to increase farmers' income.

Recommendations

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

Selection of Appropriate Genotypes: Farmers and researchers should select sweet potato genotypes that are suitable for the local climate and soil conditions to increase plant growth and production.
Application of Right Form of Beds: The form of beds used in cultivation should be appropriate to the type of sweet potato being grown to optimize crop yields.
Development of More Effective Cultivation Strategies: Further research is needed to develop more effective cultivation strategies that take into account the interaction between genotype and form of beds.

Limitations of the Study

This study has several limitations that should be noted:

Limited Sample Size: The sample size used in this study was limited, which may have affected the accuracy of the results.
Limited Number of Genotypes: Only four sweet potato genotypes were used in this study, which may not be representative of the diversity of sweet potato genotypes available.
Limited Number of Forms of Beds: Only three forms of beds were tested in this study, which may not be representative of the diversity of cultivation practices available.

Future Research Directions

Future research should focus on:

Investigating the Interaction between Genotype and Form of Beds: Further research is needed to investigate the interaction between genotype and form of beds to develop more effective cultivation strategies.
Developing More Effective Cultivation Strategies: Further research is needed to develop more effective cultivation strategies that take into account the interaction between genotype and form of beds.
Investigating the Effect of Other Factors on Growth and Production: Further research is needed to investigate the effect of other factors, such as climate, soil, and pests, on growth and production of sweet potatoes.
