Abstract

This experiment investigated the effects of three different types of fertilizers organic, chemical, and slow-release on the growth of tomato plants. Over a period of eight weeks, plants were monitored for growth parameters including height, leaf count, and fruit yield. Results indicated that the chemical fertilizer produced the highest growth rates and fruit yield, while the organic fertilizer was found to be the most environmentally friendly option with moderate growth. Slow-release fertilizers showed consistent growth but were less effective in terms of yield compared to the chemical options.

Introduction

Horticultural practices often rely on fertilizers to enhance plant growth and productivity. This study aims to compare the effectiveness of three different fertilizer types—organic, chemical, and slow-release—on tomato plant growth. The hypothesis is that chemical fertilizers will result in the highest plant growth and fruit yield due to their rapid nutrient release. This research is significant as it helps in selecting the most effective and sustainable fertilizer for tomato cultivation.

Materials and Methods

Materials:

• Tomato plants (Solanum lycopersicum), 10 per treatment

• Organic fertilizer (e.g., compost)

• Chemical fertilizer (e.g., NPK 20-10-10)

• Slow-release fertilizer (e.g., Osmocote)

• Pots (10 cm diameter)

• Soil (standard potting mix)

• Measuring tools (ruler, scale)

• Watering can

Methods:

1. Preparation: Ten pots were filled with standard potting mix. Each pot was labeled according to the fertilizer type to be used.

2. Planting: Tomato seedlings were planted in each pot.

3. Fertilization:

   • Organic fertilizer was applied according to package instructions.

   • Chemical fertilizer was applied at a rate of 5 grams per pot.

   • Slow-release fertilizer was applied according to package instructions.

4. Monitoring: Plants were watered regularly and observed for height, leaf count, and fruit development every week.

5. Data Collection: At the end of the eight-week period, data on plant height, number of leaves, and fruit yield were recorded.

Discussion

The data demonstrates that chemical fertilizers lead to the highest plant height and fruit yield, supporting the hypothesis that rapid nutrient release enhances growth. Organic fertilizers, while less effective in terms of growth metrics, are preferable from an environmental standpoint. Slow-release fertilizers provided moderate growth but were less effective than both chemical and organic options in terms of fruit yield. These findings suggest a trade-off between environmental impact and growth efficiency when choosing fertilizers.

Conclusion

Chemical fertilizers offer the best growth results for tomato plants but may have environmental drawbacks. Organic fertilizers are a more sustainable option but provide lower yields. Slow-release fertilizers offer a balanced approach but are less effective than chemical fertilizers. Further research could explore long-term effects and sustainability of these fertilizers in different horticultural settings.
