1、Effect of foliar application of urea on the growth and yield of tomato

The 10000 ppm application gave the highest yield (63.69 t/hm 2) with the lowest (28.48 t/hm 2) in the control treatment. The yield per plant as well as per hectare increased with increasing concentrations of foliar application of urea fertilizer.

2、Foliar and soil fertilization of humic acid affect productivity and quality of tomato

The study shows that 20 ml/l concentration of HA sprays could be successfully used to obtain better growth and yield in tomato. Humic acid, which has hormone-like activity, not only enhances plant growth and nutrient uptake but also improves stress tolerance.

3、Growth and quality of cucumber, tomato, and green bean under foliar and soil applications of an aminochelate fertilizer

Plant growth, yield, and quality parameters significantly increased in response to foliar application, and to lesser extent soil application of aminochelate fertilizer.

Determination of optimal fertilizer concentration range for tomatoes grown in peat

The plants were irrigated starting with 100 mL of fertilizer solution per day and increasing to 200 mL per day as plant growth progressed. The tomatoes were harvested at three stages of growth (5-leaf stage, flower initiation, and fruit formation) for analysis of growth and composition.

Influence of potassium fertilization and foliar application of zinc and phosphorus on growth, yield components, yield and fiber properties of Egyptian

Under the conditions of this study, applying K fertilization at 47.4 kg ha −1 combined with spraying cotton plants with zinc at 57.6 g ha −1 and also with P at 1 728 g ha −1 improved growth and yield of Egyptian cotton.

A Novel Nutrient

As a first report, this study was scheduled to investigate the foliar application of NABF on growth and production traits, physio-biochemical attributes, water use efficiency (WUE), and nutritional, hormonal, and antioxidative status of tomato plants cultivated under full watering (100% of ETc) and DS (80 or 60% of ETc).

Synergistic effects of Fe nanocomplex and nitrophenolate

This study examines the dose-dependent synergistic effect of foliar-sprayed iron nanocomplex (Fe NC; 0%, 0.2%, 0.4% w/v) and the nitrophenolate biostimulant Atonik (0, 125, 250 ppm) on tomato (Solanum lycopersicum) seedlings under controlled greenhouse conditions. This novel approach integrates nanotechnology and green biostimulants to enhance plant growth and physiological performance ...

Optimizing Tomato (Solanum lycopersicum L.) Growth With Different Combinations of Organo

The results showed that the combination organo-mineral fertilizers had a significant effect on tomato plant productivity. Application of neem seed cake and mineral fertilizers was the most efficient treatment with a yield increase of 53% and 40% in 2019, respectively. In 2020, the yield increase was 32 and 85% for biochar and biosol, respectively.

Absorption of foliar

Using synchrotron-based X-ray fluorescence microscopy for in situ analyses of hydrated leaves, we found that upon foliar application of ZnSO 4, Zn accumulated within 15 min in some non-glandular trichomes in soybean, but not in tomato.

Optimal fertilizer application for Panax notoginseng and effect of soil water on root rot disease and saponin contents

In order to obtain larger yields, large amounts of chemical, organic, and/or foliar fertilizers are applied during P. notoginseng cultivation, although their influence on root yield and quality is poorly understood.

The appropriate dosage of foliar fertilizer for tomatoes varies depending on the type of fertilizer, the growth stage of the tomato plants, and soil conditions. Below are some general recommendations, but adjustments should be made based on specific circumstances in practice.

1. Choose the Right Foliar Fertilizer

Various foliar fertilizers are available on the market, including essential nutrients like nitrogen (N), phosphorus (P), and potassium (K), as well as microelements such as iron (Fe), zinc (Zn), and copper (Cu). Select fertilizers based on the growth needs of tomatoes and target yields. For example:

• During vigorous growth stages: Use fertilizers rich in N, P, and K.
• During fruiting stages: Prioritize phosphorus and potassium supplements.

2. Determine the Application Rate

Adjust the dosage according to the growth stage and soil conditions:

• Vigorous growth stage: 50–100 milliliters (mL) of foliar fertilizer per mu (~0.067 hectare) per application.
• Fruiting stage: 30–50 mL of foliar fertilizer per mu per application.

3. Timing of Application

Apply foliar fertilizer in the morning or evening when temperatures are lower, as this promotes absorption and reduces the risk of leaf burn. Avoid prolonged exposure to direct sunlight after spraying.

4. Dilution Ratio

Follow the manufacturer’s instructions for dilution. A typical ratio is 100 mL of foliar fertilizer diluted in 1000–1500 mL of water. Different brands may vary, so always check the label.

5. Uniform Spraying

Use a sprayer to apply the diluted solution evenly across the leaves. Avoid spraying directly on fruits to prevent quality issues, and take care not to damage other plant parts, which could lead to phytotoxicity.

6. Precautions

• Monitor plants for signs of over-fertilization, such as leaf yellowing or wilting. If observed, stop application immediately and take remedial measures.
• Apply foliar fertilizer every 7–10 days, avoiding excessive frequency.

7. Combine with Other Fertilizers

Foliar fertilizers can be used alongside organic fertilizers or compound fertilizers to enhance efficiency. test compatibility first, as mixing certain fertilizers may cause chemical reactions that reduce effectiveness.

8. Continuous Monitoring

Regularly observe tomato growth and the effects of foliar fertilization. Adjust application rates, timing, and methods as needed to optimize results.

Foliar fertilization is an effective way to improve tomato yield and quality. Success depends on selecting the right fertilizer, applying appropriate dosages, timing applications correctly, and observing plant responses. With reasonable fertilization management, tomatoes can thrive in optimized conditions, leading to higher productivity.
