The Effect of Planting Distance and Administration of NPK Fertilizer on the Growth and Production of Okra Plants (Abelmoschus Esculentus)

Introduction

Okra (Abelmoschus esculentus) is one of the most widely cultivated horticultural commodities in the world, with a high potential in the agricultural sector. The crop is rich in nutrients and has various health benefits, making it a popular choice among farmers and consumers alike. However, the growth and production of okra plants can be influenced by several factors, including planting distance and the administration of NPK fertilizer. This study aims to investigate the effect of these two factors on the growth and production of okra plants.

Methodology

This study employed a factorial randomized group (rack) design with two treatment factors. The first factor was the spacing (J) consisting of three levels: J1 (60 x 30 cm), J2 (80 x 30 cm), and J3 (100 x 30 cm). The second factor was the administration of NPK fertilizer (N) consisting of four levels: NO (0 g/plant), Ni (5 g/plant), N2 (10 g/plant), and N3 (15 g/plant). The experiment was conducted in a controlled environment, and the data was collected and analyzed using statistical methods.

Results

The results of this study showed that the planting distance had a significant effect on plant height at the ages of 3 and 6 weeks after planting (MST), harvest age, number of pods, pod weight per sample, and total pod weight per plot. However, the effect of planting spacing on the number of branches and flowering age was not significant. On the other hand, the administration of NPK fertilizer also showed a significant effect on plant height at 6 MST, harvest age, number of pods, pod weights per sample, and total pod weight per plot. However, for plant height at the age of 2, 4, and 5 MST, the number of branches, and flowering age, the effect was not significant.

Interaction between Planting Distance and NPK Fertilizer

The interaction between the treatment of planting distance and NPK fertilizer had a significant impact on the age of the harvest, the number of pods, the weight of the pods per sample, and the total weight of the pod per plot. However, this interaction did not show a significant effect on plant height, number of branches, and flowering age.

Discussion

The effect of spacing on the growth of okra plants is a crucial factor to consider. The ideal spacing can increase air circulation and sufficient lighting, which can encourage plant growth and production. On the other hand, tight spacing can cause competition between plants to get nutrition and sunlight, while too far spacing can result in land waste and management inefficiency.

NPK fertilizer also plays a vital role in maximizing plant growth. NPK fertilizer provides nutrients needed by plants, such as nitrogen (N), phosphorus (P), and potassium (K). These nutrients contribute to vegetative growth, flowering, and finally, yields. The use of proper NPK fertilizer and according to the dose can increase the production of okra plants. However, it is essential to pay attention to the dose of fertilizer given so as not to cause negative effects, such as root burning or environmental pollution.

When both factors (planting distance and NPK fertilizer) are combined, the impact will be more complex. The interaction between spacing and fertilizer can create optimal conditions for plants to grow, but can also bring up new challenges. Therefore, further research and careful agricultural practices are needed to find the most effective combination.

Conclusion

This study provides important insights into the effect of planting distance and NPK fertilizer on the growth and production of okra plants. By understanding these factors, farmers can take appropriate steps in the cultivation of okra plants, so as to maximize the results of production and improve welfare. This research also highlights the need for further research and careful agricultural practices to find the most effective combination of planting distance and NPK fertilizer.

Recommendations

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

  1. Optimal spacing: The optimal spacing for okra plants is 60 x 30 cm, which can increase air circulation and sufficient lighting, encouraging plant growth and production.
  2. Proper NPK fertilizer: The use of proper NPK fertilizer and according to the dose can increase the production of okra plants. However, it is essential to pay attention to the dose of fertilizer given so as not to cause negative effects.
  3. Interaction between spacing and fertilizer: The interaction between spacing and fertilizer can create optimal conditions for plants to grow, but can also bring up new challenges. Therefore, further research and careful agricultural practices are needed to find the most effective combination.

Future Research Directions

This study highlights the need for further research in the following areas:

  1. Effect of other factors: The effect of other factors, such as soil type, climate, and pest management, on the growth and production of okra plants needs to be investigated.
  2. Optimal combination of spacing and fertilizer: The optimal combination of spacing and fertilizer needs to be determined through further research and experimentation.
  3. Sustainable agricultural practices: The development of sustainable agricultural practices that minimize the use of chemical fertilizers and pesticides is essential for the long-term sustainability of okra production.

Limitations of the Study

This study has several limitations, including:

  1. Small sample size: The sample size of this study was small, which may limit the generalizability of the findings.
  2. Limited scope: This study only investigated the effect of planting distance and NPK fertilizer on the growth and production of okra plants, and did not consider other factors that may influence plant growth.
  3. Experimental design: The experimental design of this study was limited, and may not have captured the full range of interactions between the treatment factors.

Conclusion

In conclusion, this study provides important insights into the effect of planting distance and NPK fertilizer on the growth and production of okra plants. By understanding these factors, farmers can take appropriate steps in the cultivation of okra plants, so as to maximize the results of production and improve welfare. This research also highlights the need for further research and careful agricultural practices to find the most effective combination of planting distance and NPK fertilizer.
