Optimizing the Growth of Aquilaria Malaccensis Lamk Seeds through the Frequency of Spraying Leaf Fertilizer (Gandasil D)

Introduction

Aquilaria Malaccensis Lamk, a slow-growing tree species, holds great potential as an industrial crop and supports reforestation and greening efforts in Indonesia. To obtain high-quality seeds from Aquilaria Malaccensis, it is crucial to test the frequency of spraying leaf fertilizer, specifically Gandasil D, and the appropriate level of shade. This study aimed to investigate the effect of the frequency of spraying leaf fertilizer and shade on the growth of Aquilaria Malaccensis seeds.

Background

Aquilaria Malaccensis Lamk is a tree species that grows slowly, making it challenging to cultivate. However, its potential as an industrial crop and its role in supporting reforestation and greening efforts in Indonesia make it an important species to study. To optimize the growth of Aquilaria Malaccensis seeds, it is essential to understand the effect of the frequency of spraying leaf fertilizer and shade on plant growth parameters.

Research Methods

This study was conducted on open land in front of the Faculty of Agriculture, University of North Sumatra, from March to May 2014. The research methodology used a random factorial design, complete with two factors: the frequency of spraying leaf fertilizer (Gandasil D) and the shade level (0%, 35%, and 75%). Various plant growth parameters were measured, including the height of the seeds, stem diameter, number of leaves, leaf area, canopy wet weight, fresh root weight, canopy dry weight, and root dry weight.

Research Results

The results showed that the frequency of spraying leaf fertilizer had a significant effect on all seed growth parameters. The more often spraying is done, the better the growth of Aquilaria Malaccensis seeds. However, the effect of shade only has a significant effect on increasing the diameter of the seed stems. The interaction between the frequency of spraying fertilizer and shade does not show a significant effect on all measured parameters.

Analysis and Explanation

The increasing growth of Aquilaria Malaccensis seeds produced from the frequency of spraying leaf fertilizer can be explained by the nutritional content contained in Gandasil D. This leaf fertilizer contains macro and micro nutrition, which is essential to support the process of photosynthesis and metabolism of plants. By providing adequate nutritional intake, plants can grow more optimally.

Conversely, the results that indicate that the shade does not significantly affect all parameters, except the stem diameter, suggest that Aquilaria Malaccensis may be more adaptive in open conditions. However, shade still has a positive effect on the diameter, which can help strengthen the structure of the stem to deal with hard environmental conditions.

Conclusion

This study highlights the importance of the frequency of spraying leaf fertilizer in supporting the growth of Aquilaria Malaccensis seeds. To achieve maximum results in aquilaria cultivation, farmers and farmers must pay attention to the frequency of spraying fertilizer and consider the appropriate use of shade. Through a better understanding of these growth factors, it is hoped that the development of Aquilaria Malaccensis can run more efficiently and sustainably, supporting greening and industrial efforts in Indonesia.

Recommendations

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

Frequency of spraying leaf fertilizer: The frequency of spraying leaf fertilizer should be increased to optimize the growth of Aquilaria Malaccensis seeds.
Shade level: The shade level should be adjusted to 0% to 35% to promote the growth of Aquilaria Malaccensis seeds.
Nutritional content: The nutritional content of Gandasil D should be analyzed to determine its effect on plant growth parameters.
Adaptability: The adaptability of Aquilaria Malaccensis to open conditions should be further studied to determine its potential as an industrial crop.

Future Research Directions

Future research should focus on the following areas:

Optimizing the frequency of spraying leaf fertilizer: The frequency of spraying leaf fertilizer should be optimized to determine its effect on plant growth parameters.
Shade level and plant growth: The effect of shade level on plant growth parameters should be further studied to determine its potential as a growth factor.
Nutritional content and plant growth: The nutritional content of Gandasil D should be analyzed to determine its effect on plant growth parameters.
Adaptability and industrial potential: The adaptability of Aquilaria Malaccensis to open conditions should be further studied to determine its potential as an industrial crop.

Limitations of the Study

This study has several limitations, including:

Sample size: The sample size of this study was limited, which may affect the reliability of the results.
Experimental design: The experimental design used in this study may not be representative of all possible experimental designs.
Shade level: The shade level used in this study may not be representative of all possible shade levels.

Conclusion

In conclusion, this study highlights the importance of the frequency of spraying leaf fertilizer in supporting the growth of Aquilaria Malaccensis seeds. The results of this study suggest that the frequency of spraying leaf fertilizer has a significant effect on all seed growth parameters, while the effect of shade only has a significant effect on increasing the diameter of the seed stems. The interaction between the frequency of spraying fertilizer and shade does not show a significant effect on all measured parameters.
