1、Growth and yield responses of tomatoes to sources and rates of organic manures in ferralitic soils

Four organic manures and NPK fertilizer, each at four rates, were assessed under field conditions for their comparative effects on tomato growth and yield. Tomato fruit yields (49 and 47 t ha −1) were best with swine or poultry manure applied at the rate of 10 t ha −1.

2、The use of microalgae as a high

This indicates that nutrients recovered through microalgae cultivation can be recycled as microalgae-based fertilizers to improve the quality and market value of high-value fruits such as tomatoes. The aim of this study was to assess the potential of microalgae as an organic slow-release fertilizer for tomato cultivation.

3、Towards a more sustainable fertilization: Combined use of compost and inorganic fertilization for tomato cultivation

Inorganic vs. combined organic and inorganic fertilizers have been tested for tomato. Compost addition improves the efficiency of the inorganic fertilizers. Microbial soil characteristics are improved with the use of combined fertilization. Mineral N can be reduced with combined fertilization while obtaining similar yields.

Impact of organic and inorganic fertilizers on yield, taste, and nutritional quality of tomatoes

In a greenhouse experiment, tomato plants were grown in sand culture to test whether different fertilization regimes (mineral or organic fertilizers) at low (500 mg N plant –1 week –1) and high (750 mg N plant –1 week –1) nitrogen levels affected yield, nutritional quality, and taste of the fruits.

The Influence of Different Organic Fertilizers on Yield and Physico

Organic nutrient sources including compost, manure, compost extract, and authorized fertilizers could be combined and used in order to achieve a balanced nutrient supply and an improved organic tomato yield and quality.

Effect of Organic Fertilizers Used in Washed Soil on the Growth of Tomatoes

Organic fertilizers can be helpful to improve the plant height, stem diameter, the aerial parts fresh weight, root fresh weight, leaf photosynthetic rates and photosynthesis, and lay a good foundation for the growth of tomatoes. The effect of organic fertilizers is the most significant.

Effect of organic fertilizers used in sandy soil on the growth of tomatoes

Organic fertilizers can be help- ful to improve the plant height, stem diameter, the aerial parts fresh weight, root fresh weight, leaf photosynthetic rates and photosynthesis, and lay a good foundation for the growth of tomatoes. The effect of organic fertilizer is the most significant.

Vermicompost as an effective organic fertilizer and biocontrol agent: effect on growth, yield and quality of plants

In the present review, vermicompost is described as an excellent soil amendment and a biocontrol agent which make it the best organic fertilizer and more eco-friendly as compared to chemical fertilizers. Vermicompost is an ideal organic manure for better growth and yield of many plants.

Lesquerella press cake as an organic fertilizer for greenhouse tomatoes☆

The press cake contains levels of nutrients which should make it an excellent organic fertilizer for container-grown plants. Tomato (Solanum lycopersicum L. ‘Red Robin’) plants were grown in potting mix supplemented with a standard chemical fertilizer mix or either lesquerella press cake or cottonseed meal at rates of 2.5, 5.0 and 10.0% (w/w).

Effect of different organic fertilizers application on growth and environmental risk of nitrate under a vegetable field

For the first rotation, tomato yield increased by 9.2–20.1% compared with CK. Among this, ROF did best with the yield of 84.9 t·ha −1 and it was significantly higher than other treatments....

As a widely cultivated vegetable, tomato growth heavily relies on proper fertilization. Selecting the right organic fertilizers is critical to enhancing tomato yield and quality. Below is a detailed introduction to the types and characteristics of organic fertilizers suitable for tomatoes:

I. Organic Fertilizers

1. Chicken Manure: One of the most common organic fertilizers, chicken manure is rich in organic matter and trace elements. It improves soil structure, enhances water retention, and boosts fertility. Additionally, its amino acids and vitamins promote tomato growth and fruit quality.
2. Cow Manure: Similar to chicken manure, cow manure provides balanced nitrogen (N), phosphorus (P), and potassium (K) ratios, offering comprehensive nutrients for tomatoes. It also regulates soil pH, activates microbial activity, and supports healthy plant growth.
3. Compost: Made from decomposed agricultural waste (e.g., straw, leaves), compost releases nutrients slowly via beneficial microorganisms. It reduces pest risks, improves soil aeration and water retention, and creates an optimal growing environment for tomatoes.

II. Inorganic Fertilizers

1. Bone Meal: A premium calcium source, bone meal supplies essential calcium for fruit development and maturity. Its phosphorus content strengthens root systems, enhancing disease resistance and drought tolerance.
2. Superphosphate: A fast-acting phosphorus fertilizer, superphosphate promotes root growth and fruit expansion. It also improves stress resistance and strengthens defenses against pests and diseases.
3. Calcium Nitrate: This efficient nitrogen source rapidly replenishes soil nitrogen, supporting tomato growth. It boosts photosynthesis, increases sugar accumulation in fruits, and enhances overall quality.

III. Compound Fertilizers

1. NPK Fertilizer: A balanced blend of nitrogen (N), phosphorus (P), and potassium (K), compound fertilizers provide tailored nutrition for tomatoes at different growth stages. They simplify application processes and improve fertilization efficiency.
2. Controlled-Release Fertilizers: These long-lasting fertilizers release nutrients slowly or in controlled doses, ensuring steady nutrient supply over time. They reduce labor intensity, minimize environmental loss, and enhance fertilization outcomes.

IV. Key Considerations

1. Timing of Fertilization:

   • Seedling and Flowering Stages: Prioritize nitrogen-rich fertilizers to promote growth and flower/fruit formation.
   • Fruit Enlargement Stage: Focus on phosphorus and potassium to improve fruit development and quality. Adjust nutrient ratios based on growth phases.

2. Application Methods:

   • Deep application (vs. shallow) improves nutrient absorption by reaching deeper soil layers. Avoid direct contact with roots to prevent burning.

3. Dosage Control:

   • Over-fertilization raises soil salinity, harming plants, while insufficient amounts limit growth. Balance dosage according to soil fertility, crop needs, and weather conditions.

Optimal tomato cultivation relies on combining organic and inorganic fertilizers while considering timing, methods, and dosage. Proper fertilization practices not only boost yield and quality but also protect soil health, advancing sustainable agricultural production.
