1、Foliar application of plant growth regulators (PGRs) and nutrients for improvement of lily flowers

Foliar application of nutrients and plant growth regulators may improve flower quality parameters. Gibberellins possess a variety of functions in vegetative and reproductive phases of plant life cycle.

2、Copper

The foliar application of Fe and Zn significantly increased flower yield and essential oil content of chamomile in calcareous soils (Nasiri et al., 2010) and the application of foliar potassium and phosphorus nutrition via Nutri-Vant-Peak accelerated fruit maturation and improved fruit quality in greenhouse tomatoes (Chapagain and Wiesman, 2004).

3、Foliar Fertilization of Crop Plants: Journal of Plant Nutrition: Vol 32 , No 6

Soil applications of fertilizers are mainly done on the basis of soil tests, whereas foliar nutrient applications are mainly done on the basis of visual foliar symptoms or plant tissue tests. Hence, correct diagnosis of nutrient deficiency is fundamental for successful foliar fertilization.

4、Foliar Fertilization for Sustainable Crop Production

Foliar feeding is one method which can meet the requirement as a supplement to soil feeding in many cases. Bi and Scagel (2007) recommend foliar N application for raising nursery plants. While this can correct the N deficiency in the early growth stages, it can decrease the amount of total N necessary and minimize N runoff.

Effect of Foliar Applied Urea on Growth and Yield of Sunflower (Helianthus annuus L.)

The results showed that foliar application of urea was markedly effective to increase grain yield ha−1 of sun-flower; and foliar application of urea in addition to 130 kg·ha−1 soil applied urea after 35 days of sowing surpassed all other treatments including delayed foliar application.

Effects of chemical and organic fertilizers on the growth, flower quality and nutrient uptake of Anthurium andreanum, cultivated for cut flower production

In short, the organic fertilizer PRHC can meet the nutrient requirements of A. andreanum cultivation for the cut flower production under soilless conditions. 1. Introduction. The Anthurium (Anthurium andreanum Lind.) is one of the most important cut flowers among tropical plants (Galinsky and Laws, 1996).

The Effects of Foliar Sprays with Different Silicon Compounds

Foliar sprays with silicates are effective as pesticides, while (stabilized) silicic acid sprays increase growth and yield and decrease biotic and abiotic stresses. The limited data on foliar silica-nano sprays show a tendency to decrease biotic stress and to stimulate a limited increase in growth and yield.

Revisiting fertilisers and fertilisation strategies for improved nutrient uptake by plants

Foliar fertilisation may directly affect the yield and quality of leafy vegetables, yet this pathway may be less effective in cereals if foliar-applied nutrients are less mobile and thus more assimilated in leaf tissues, rather than being translocated to the grains.

Effect of dose and type of fertilizer on flowering and fruiting of vanilla plants

Application of fertilizer to the substratum appears to improve reproductive parameters of vanilla plants and the production of beans, while foliar fertilization alone was ineffective in increasing crop productivity.

Evaluation of mother corm weights and foliar fertilizer levels on saffron

Totaling, 15% concentration of foliar fertilizer and 5–10 g mother corms were the most favorable condition for the entire vegetative and reproductive traits of saffron in this study. 1. Introduction. Saffron (Crocus sativus L.) is a perennial herbaceous plant from Iridaceae family (Arslan et al., 2013).

When selecting a foliar fertilizer, it is essential to consider the specific needs of the plants, their growth stages, and soil conditions. Below are several common types of foliar fertilizers, their characteristics, and applicable scenarios:

1. Potassium Dihydrogen Phosphate (KH₂PO₄): This is a widely used foliar fertilizer containing phosphorus and potassium, which significantly promotes plant growth and enhances disease resistance. It is suitable for various plants, especially during their growth phases when additional nutrients are needed.

2. Urea (NH₄NO₃): Urea is a high-nitrogen fertilizer that rapidly provides a large amount of nitrogen, accelerating plant growth. excessive use may cause overly rapid growth, weak stems, and potential suckering (excessive elongation). application should be adjusted based on the plant’s growth condition and soil fertility.

3. Borax (Boric Acid Salt): Boron is a vital microelement for plant growth, improving photosynthetic efficiency, stress resistance, and flower bud differentiation. Borax is suitable for many plants, particularly fruit trees and flowers.

4. Zinc Sulfate (ZnSO₄): Zinc is a component of multiple enzymes in plants and participates in growth processes. Proper zinc fertilization promotes root development and enhances plant resilience. It is effective for various plants, especially those deficient in zinc.

5. Iron(II) Sulfate (FeSO₄): Iron is critical for photosynthesis, respiration, and chlorophyll formation. Iron-based fertilizers are ideal for plants, especially those exhibiting iron deficiency.

6. Microelement Composite Fertilizers: These fertilizers contain multiple microelements (e.g., manganese, copper, molybdenum), comprehensively addressing nutritional deficiencies. They are a good choice for plants lacking specific microelements.

Additional Considerations for Selecting Foliar Fertilizers:

1. Soil Conditions: Soil pH and nutrient levels affect fertilizer effectiveness. For example, acidic soils may require alkaline additives to adjust pH.

2. Plant Species: Different plants have varying nutritional needs, so choose fertilizers based on species and growth stages.

3. Timing: Apply foliar fertilizers during peak growth or before/after flowering for optimal results.

4. Dosage: Adjust amounts according to plant size, growth status, and soil fertility. Excessive use can cause nutrient burn, while insufficient doses may fail to deliver desired outcomes.

5. Application Method: Spray directly onto leaves using a fogger or mix with water for irrigation. Proper methods improve absorption efficiency.

no single foliar fertilizer suits all plants or growth stages. For best results, tailor your choice to specific conditions, apply appropriately, and monitor dosages to achieve optimal efficacy.
