1、Foliar application of chitosan activates artemisinin biosynthesis in Artemisia annua L.

Here we show that foliar application of 100 mg l −1 chitosan improved artemisinin biosynthesis in A. annua. The content of dihydroartemisinic acid and artemisinin in chitosan-treated leaves increased by 72% and 53% compared with control values, respectively.

2、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.

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.

Foliar fertilizers have attracted increasing attention over the last few decades as they offer the most efficient way to correct micronutrient deficiencies and enhance the product yield and quality of crops and plants. The micronutrients are essential to physiological functions in plant metabolism, and leaf uptake

5、Studies of changes in chlorophyll content in Artemisia annua L. under the effects of biological and chemical fertilizers

In order to consider biological fertilizers (Nitroxin, Bio-phosphorus and Vermicompost) and chemical fertilizers (N, P) on chlorophyll content Artemisia annua L., we had done an experiment in Zabol University green house in 2011. The plan of this experiment was factorial design in completely randomized design with 4 replications.

micronutrient chelates and soil can be avoided by using a foliar application. Chelated nutrients also facilitate nutrient uptake eficiency for foliar application because crop leaves are naturally

COMPARISON OF DIFFERENT FOLIAR

Foliar fertilizers reduce the potential for nutrients to accumulate in soil, move in run-off to surface waters (streams, lakes, ocean), and leach into the groundwater (drinking water supply), where they can contribute to salinity, eutrophication and nitrate contamination, leading to deleterious effects on the environment and human health.

Fertilizer placement to improve crop nutrient acquisition and yield: A review and meta

The objectives of this paper are: (1) to summarize current techniques for fertilizer placement in soil and to identify fertilizers that are suitable for subsurface placement; and (2) to quantify the relative effects of fertilizer placement to fertilizer broadcast on crop nutrient acquisition and yield.

Artemisia (scientific name: Liguaria rhizome), also known as Lu fault or mugwort, is a vegetable widely cultivated in Asia, particularly in China. Renowned for its unique flavor and nutritional value, Artemisia is commonly used in various culinary dishes, such as cold salads and stir-fries. Its tender stems and leaves, rich in essential nutrients, significantly promote plant growth.

When selecting foliar fertilizers for Artemisia, priority should be given to products that provide essential nutrients, enhance plant immunity, and support healthy growth. Below is a detailed exploration of several types of foliar fertilizers suitable for Artemisia, along with their characteristics:

1. Seaweed Extracts: Derived from natural sources, seaweed extracts contain trace elements and vitamins that promote plant growth and development. For plants requiring micronutrient supplementation, seaweed extracts are an excellent choice. For example, calcium, iron, and zinc in seaweed extracts can effectively improve Artemisia’s disease resistance, stimulate root development, and enhance overall plant health.

2. Amino Acid Compound Fertilizers: Amino acids are critical nutrients for plant growth. When applied foliarly, they are rapidly absorbed and utilized, improving stress resistance and accelerating growth. These fertilizers typically contain nitrogen (N), phosphorus (P), and potassium (K), meeting Artemisia’s nutrient demands at different growth stages. Foliar application of amino acid fertilizers can boost yield and quality while reducing synthetic chemical fertilizer use.

3. Bio-Bacterial Agents: Microbial inoculants, such as plant growth-promoting bacteria and nitrogen-fixing bacteria, enhance plant growth by improving soil environments. These microorganisms form beneficial communities around roots, increasing soil microbial diversity, which strengthens nutrient absorption and disease resistance. For Artemisia, bio-bacterial agents promote root development, improve soil water-retention and fertility, and foster healthy growth.

4. Organic Fertilizers: Organic fertilizers, such as compost and humic acid, are fully fermented organic matter rich in humus and nutrients. Foliar application not only supplies essential nutrients but also improves soil structure, enhances aeration and water retention, and supports robust root systems.

5. Trace Element Fertilizers: Besides major nutrients like N, P, and K, trace elements (e.g., boron, manganese, molybdenum) are crucial for plant growth. Foliar application of these micronutrients boosts disease resistance, reproductive growth, and quality. For Artemisia, balanced supplementation of trace elements ensures normal development, higher yields, and improved quality.

6. Slow-Release Fertilizers: Slow-release fertilizers provide extended nutrient availability, reducing application frequency and labor. Available in solid or liquid forms, they maintain steady nutrient supply. For Artemisia, slow-release fertilizers minimize environmental pollution from excessive applications and help balance soil nutrients.

7. Water-Soluble Fertilizers: These fertilizers dissolve quickly in water for direct plant absorption. High in N, P, and K, they allow precise dosage control. Foliar spraying of water-soluble fertilizers rapidly nourishes Artemisia, accelerating growth. excessive use should be avoided to prevent salt accumulation and nutrient imbalance.

selecting appropriate foliar fertilizers is vital for promoting healthy Artemisia growth. Choices should align with the plant’s growth stage and specific needs, combined with rational application methods. Integrating foliar fertilization with other agricultural practices—such as irrigation management and pest control—maximizes benefits, ensuring high yields and superior quality.
