Reveping the Secret of Growth of Palm Oil Seeds in the Copy Soil: The Role of Gandasil Leaf Fertilizer D

Introduction

Palm oil (Elaeis guineensis Jacq.) is one of the most widely cultivated crops in the world, with Indonesia being the largest producer. However, the cultivation of palm oil in saline soils poses a significant challenge due to the high level of salt that can inhibit plant growth. To overcome this challenge, researchers have been exploring various strategies to increase productivity, including the use of fertilizers. One such fertilizer is Gandasil leaf fertilizer D, which has been shown to have a positive effect on plant growth. In this article, we will discuss the results of a study conducted by Savitri (2010) on the effect of concentration and intervals of giving Gandasil D leaves on the growth of oil palm seedlings planted in saline soil.

Background

Saline soils are a major constraint to palm oil production, as the high level of salt can lead to reduced plant growth, lower yields, and decreased quality of the oil. To overcome this challenge, researchers have been exploring various strategies to increase productivity, including the use of fertilizers. Gandasil leaf fertilizer D is one such fertilizer that has been shown to have a positive effect on plant growth. This fertilizer is a type of organic fertilizer that is derived from the leaves of the Gandasil plant, which is native to Indonesia.

Methodology

The study conducted by Savitri (2010) used a factorial random group design (shelves) with three factors, namely:

  • Layer of Soil: Topsoil (T1) and Subsoil (T2)
  • Concentration of Gandasil Fertilizer D: 1 g/L Water (K1), 2 g/L Water (K2), and 3 g/L Water (K3)
  • Interval Time Fertilizer: Every 7 days (i1), every 14 days (i2), and every 21 days (i3)

The study observed several parameters, including plant height, base diameter, leaf area, root length, canopy dry weight, root dry weight, number of chlorophyll, net assimilation rate, relative growth rate, root canopy ratio, and leaf prolina levels.

Results

The results of the study showed that the treatment T1K2I1 (topsoil, fertilizer concentration 2 g/l water, and intervals of 7 days) produced the best growth in general. This treatment produced the highest average for plant height, base diameter, leaf area, and dry weight canopy at various ages of plants. However, the treatment T1K1i3 (topsoil, 1 g/l fertilizer concentration, and intervals every 21 days) actually gave the best results for root length and root dry weight. This shows that the use of lower fertilizer concentrations with giving intervals longer can encourage better root growth.

Discussion

The results of the study imply that the use of Gandasil D leaves can increase the growth of oil palm seedlings in saline soil. However, the concentration and interval of appropriate fertilizer administration must be adjusted to the condition of the soil and plant needs. The study also highlights the importance of considering the layer of soil, as the results showed that the treatment T2K3I2 (subsoil, concentration of fertilizer 3 g/l of water, and intervals every 14 days) produced the highest leaf prolina levels. Prolina is a compound that plays a role in tolerance of stress, including salt stress.

Conclusion

This study proves that Gandasil D leaves can increase the growth of oil palm seedlings in saline soil. The concentration and interval of optimal fertilizer administration depends on soil conditions and plant needs. Further research is needed to examine the effectiveness of Gandasil D fertilizer on a field scale, as well as its effect on crops and survival of oil palm plantations in saline soil.

Recommendations

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

  • The use of Gandasil D leaves can be a useful strategy to increase the growth of oil palm seedlings in saline soil.
  • The concentration and interval of fertilizer administration must be adjusted to the condition of the soil and plant needs.
  • Further research is needed to examine the effectiveness of Gandasil D fertilizer on a field scale, as well as its effect on crops and survival of oil palm plantations in saline soil.

Limitations

This study has several limitations, including:

  • The study was conducted in a controlled environmental condition, which may not fully describe the field conditions.
  • The study only examined the effect of Gandasil D fertilizer on oil palm seedlings, and not on mature plants.
  • The study only examined the effect of Gandasil D fertilizer on saline soil, and not on other types of soil.

Future Research Directions

Based on the results of this study, the following future research directions can be suggested:

  • Examine the effectiveness of Gandasil D fertilizer on a field scale.
  • Examine the effect of Gandasil D fertilizer on mature oil palm plants.
  • Examine the effect of Gandasil D fertilizer on other types of soil.
  • Examine the effect of Gandasil D fertilizer on other crops.
