Introduction

The cultivation of chili peppers is a significant agricultural activity in many parts of the world, providing a valuable source of income for farmers and a staple ingredient in various cuisines. However, the growth and production of chili peppers can be influenced by various factors, including the type and amount of fertilizer used, as well as the timing of its application. In this study, we aim to investigate the effect of Grand-S15 fertilizer and the most optimal application time on the growth and production of chili peppers.

Methodology

The study was conducted in the Experimental Garden of the Faculty of Agriculture, Islamic University of North Sumatra, Johor Medan Building, at an altitude of about 25 meters above sea level, during the period February 2003 to July 2003. A factorial randomized group (rack) design was used, with two treatment factors: Grand-S15 fertilizer and application time.

The first factor, Grand-S15 fertilizer, consisted of four doses: G1 (10 g/plant), G2 (15 g/plants), G3 (20 g/plants), and G4 (25 g/plants). The second factor, application time, had four time combinations: W1 (30, 50, 70, 90 days after planting), W2 (32, 52, 72, 92 HST), W3 (34, 54, 74, 94 HST), and W4 (36, 56, 76, 96 HST).

Parameters Observed

The parameters observed in this study included:

Plant Height: measured in centimeters (cm)
Number of Branches: measured in branches
Number of Fruit per Sample: measured in fruit
Production per Sample: measured in grams (g)
Production per Plot: measured in grams (g)

Results

The results of the study showed that the treatment of Grand-S15 fertilizer significantly increased plant height, number of fruit per sample, as well as production per sample and per plot. However, there was no significant effect on the number of branches and the number of fruit per sample.

Similarly, the treatment of fertilizer application time was also proven to be effective in increasing plant height, number of fruit per sample, as well as production, but did not significantly affect the number of branches and the number of fruits.

Optimal Fertilizer Dose and Application Time

From the results of the study, it was known that the optimal Grand-S15 fertilizer dose was in the range of 20-20.94 g/plant, which produced the highest plant height of 77.55 cm, the highest number of branches reached 80.58 branches, the highest number of fruit per sample 36.83 pieces, as well as the highest sample production of 80.71 g, and the highest production per plot is 213.53 g.

Meanwhile, the most effective fertilizer application time was at 30, 50, 70, and 90 days after planting, where the highest plant height was 77.00 cm, the highest number of branches was 82.79 branches, the highest number of samples per sample was 37.63 pieces, the highest production per sample was 89.30 g, and the highest production per plot was 220.80 g.

Conclusion

Through this study, it can be concluded that the use of the right Grand-S15 fertilizer and optimal application time selection can make a significant contribution to the growth and production of chili peppers. Understanding the effect of fertilizers and the time of this application is very important for farmers in an effort to increase the yield of chili harvest, as well as ensuring the sustainability of agricultural production in the future.

Recommendations

Therefore, further research and the application of appropriate agricultural techniques are highly recommended to achieve more optimal results. This study provides valuable insights for farmers and researchers to improve the growth and production of chili peppers, ultimately contributing to the sustainability of agricultural production.

Future Directions

Future studies can build upon the findings of this research by investigating the effects of other factors, such as soil type, climate, and pest management, on the growth and production of chili peppers. Additionally, the development of more efficient and sustainable agricultural practices can be explored to improve the productivity and profitability of chili pepper cultivation.

Limitations

This study had some limitations, including the use of a small sample size and the limited number of treatment factors. Future studies can address these limitations by increasing the sample size and exploring a wider range of treatment factors.

Implications

The findings of this study have significant implications for the agricultural industry, particularly for farmers and researchers involved in chili pepper cultivation. By understanding the effects of Grand-S15 fertilizer and application time, farmers can make informed decisions about their fertilizer application and timing, ultimately improving the growth and production of their chili pepper crops.

Conclusion

In conclusion, this study provides valuable insights into the effects of Grand-S15 fertilizer and application time on the growth and production of chili peppers. The findings of this study have significant implications for the agricultural industry and highlight the importance of understanding the effects of fertilizers and application time on crop growth and production.

Q: What is Grand-S15 fertilizer?

A: Grand-S15 fertilizer is a type of fertilizer that is specifically designed to promote the growth and production of chili peppers. It contains a balanced mix of nutrients that are essential for plant growth, including nitrogen, phosphorus, and potassium.

Q: What are the benefits of using Grand-S15 fertilizer?

A: The benefits of using Grand-S15 fertilizer include:

Increased plant height: Grand-S15 fertilizer can help to promote healthy plant growth, resulting in taller and more robust plants.
Improved fruit production: Grand-S15 fertilizer can help to increase fruit production, resulting in more chili peppers per plant.
Enhanced flavor and quality: Grand-S15 fertilizer can help to improve the flavor and quality of chili peppers, making them more desirable for consumers.

Q: What is the optimal application time for Grand-S15 fertilizer?
