Characteristics Test on Several Varieties of Peanuts (Arachis Hypogaea L.)

Introduction

Peanuts (Arachis hypogaea L.) are one of the most important commodities in the world of agriculture, serving as a source of vegetable protein and an industrial raw material. The selection of suitable peanut varieties is crucial to increase agricultural productivity, especially in regions with varying soil and climate conditions. This study aimed to investigate the characteristics of several peanut varieties, including giraffe, deer, Bima, lion, and Sihobuk, to determine their potential and suitability for cultivation in North Sumatra.

Research Methodology

The study was conducted in the experimental land of the Faculty of Agriculture, University of North Sumatra, from August to November 2005. A randomized block design with five replications was used to ensure accurate results. The evaluated peanut varieties were giraffe, deer, Bima, lion, and Sihobuk. The study focused on several characteristic parameters, including plant height, number of branches, flowering age, number of ginofora, vegetative and generative phases, number of pods per sample and per plot, and seed weight per plot.

Results

The results of the study showed that the mouse deer variety had the highest potential with an average seed weight of 122.02 grams per plot, while the Bima variety had the lowest yield, with an average seed weight of 61.28 grams per plot. The study also analyzed the heritability value of various characteristic parameters. The results indicated that the seed weight parameter per plot had the lowest heritability value, while parameters such as the number of branches, flowering age, number of ginofora, vegetative and generative phases, and number of pods per sample and per plot had moderate heritability values. On the other hand, plant height had the highest heritability value.

Discussion

The importance of this research lies in the selection of appropriate peanut varieties to increase agricultural productivity. By knowing the characteristics of each variety, farmers can choose varieties that best suit the condition of the soil and climate in their area. The advantage of the mouse deer variety as a variety with high yields shows that this variety has a good adaptation to the growing environment in North Sumatra. In this case, the selection of exact varieties is very crucial, especially in the context of climate change that can affect plant productivity.

Heritability is an important factor in plant breeding, as it shows how much genetic contribution to phenotypic variations. High heritability values, as in plant height parameters, indicate that the character can be inherited consistently to the next generation. Conversely, parameters with low heritability, such as seed weight per plot, indicate that environmental factors have a greater influence on these characteristics. Therefore, researchers need to consider this aspect in the breeding program to increase the harvest of peanuts in the future.

Conclusion

This study is expected to make a positive contribution in the development of superior and productive peanut varieties, and support the sustainability of agricultural production in Indonesia. Knowledge of the characteristics of varieties and heritability can be a reference for farmers and researchers in an effort to improve agricultural output as a whole. The results of this study can be used as a basis for further research and breeding programs to develop new and improved peanut varieties that are suitable for cultivation in various regions.

Recommendations

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

The mouse deer variety is recommended for cultivation in North Sumatra due to its high yield and good adaptation to the growing environment.
Further research is needed to investigate the characteristics of other peanut varieties and their suitability for cultivation in different regions.
Breeders should consider the heritability value of characteristic parameters when developing new and improved peanut varieties.
Farmers should choose peanut varieties that best suit the condition of the soil and climate in their area to increase agricultural productivity.

Future Research Directions

Future research directions can include:

Investigating the characteristics of other peanut varieties and their suitability for cultivation in different regions.
Developing new and improved peanut varieties using breeding programs that consider the heritability value of characteristic parameters.
Investigating the effects of climate change on peanut productivity and developing strategies to mitigate its impact.
Developing sustainable agricultural practices that promote the use of peanut varieties with high yields and good adaptation to the growing environment.

Limitations of the Study

This study has several limitations, including:

The study was conducted in a single location, and the results may not be generalizable to other regions.
The study focused on a limited number of characteristic parameters, and further research is needed to investigate other parameters that may be important for peanut breeding.
The study did not investigate the effects of climate change on peanut productivity, which is an important consideration in the context of climate change.

Conclusion

In conclusion, this study provides valuable information on the characteristics of several peanut varieties and their suitability for cultivation in North Sumatra. The results of this study can be used as a reference for farmers and researchers in an effort to improve agricultural output as a whole. Further research is needed to investigate the characteristics of other peanut varieties and their suitability for cultivation in different regions, as well as to develop new and improved peanut varieties using breeding programs that consider the heritability value of characteristic parameters.
