2、The Applications and Effects of Potassium Fertilizer on Garlic

This study was aimed to demonstrate effect of adding humic acid and potassium fertilizer on the growth and yield of Garlic plants, The field experiment was carried out in Horticulture Station in Kut, affiliated with the Directorate of Agriculture of Wasit Governorate, in the fall season of 2022.

3、Response and productivity of Garlic (Allium Sativum L.) by different

Potassium (K) is a vital nutrient for increasing garlic yields. Proper application rates and timing are critical for generating a yield or quality response. As crop yield increase, the amount of K required also increases, along with all other nutrients (Mendez et al. 2001).

4、Responses of Garlic Quality and Yields to Various Types and Rates of

From 2018 to 2020, we utilized two distinct K-fertilized fields to conduct our experiments. The results revealed optimal KCl fertili-zation increased the biomass and vegetation index in garlic, and promoted the trans-fer of nitrogen, phosphorus, and potassium nutrients from the stem and leaf to bulb, thereby increasing bulb production.

Garlic farmers often seek strategies to improve yield and post-harvest storage longevity. This study investigated the impact of various supplemental potassium fertilizers on these parameters.

The Effect of Slow

The effects of these treatments on garlic seedling yield, growth quality, chlorophyll content, photosynthetic characteristics, and the soil environment were investigated to evaluate the feasibility of replacing conventional fertilizers with slow-release formulations.

Responses of Garlic Quality and Yields to Various Types

Potassium (K) is a critical plant nutrient that determines quality in a myriad of crops and increases production yields. However, excessive application of various types of K fertilizers can decrease both the food quality and yields, which translates as economic losses and food safety issues.

Garlic potassium fertilizer, also known as garlic-specific fertilizer or garlic potassium-rich fertilizer, is a specialized fertilizer designed for garlic cultivation. Rich in potassium, it helps improve garlic yield and quality, enhance disease resistance, extend the growth cycle, and enhance taste and nutritional value. Below is a detailed explanation of its functions, applications, usage methods, and precautions:

I. Functions

1. Promotes Growth: Potassium is an essential nutrient for plant growth, critical for cell division, elongation, and maturation. During garlic growth, adequate potassium aids nutrient absorption, promotes root development, and strengthens overall plant health.
2. Enhances Disease Resistance: Potassium boosts plants’ ability to resist pests and diseases. Research shows it increases antioxidant enzyme activity, reducing free radicals and lowering disease risks.
3. Extends Growth Cycle: Potassium supports starch synthesis, maintaining plant vitality. For garlic, supplemental potassium prolongs the growth cycle, increasing yield.
4. Improves Quality: Potassium enhances garlic’s color, taste, and texture. It makes the skin smoother, colors brighter, and flavors more appealing.
5. Promotes Bud Differentiation: Potassium stimulates garlic flower bud formation. Timely application during the flowering stage improves blooming and fruiting rates.
6. Increases Stress Tolerance: Potassium helps garlic withstand adverse conditions (e.g., drought, cold). It ensures normal growth under stressful environments, reducing yield losses.

II. Applications

1. Basal Application: Spread the fertilizer evenly on soil surfaces before planting, then plow to integrate it. Suitable for large-scale garlic farming, ensuring sustained potassium supply throughout the season.
2. Topdressing: Apply additional fertilizer during growth based on plant conditions and soil tests. Directly apply to soil or mix with water-soluble fertilizers for rapid nutrient replenishment.
3. Foliar Spraying: Spray the fertilizer solution onto garlic leaves using a fogging device. Effective for potassium-absorbent garlic varieties, maximizing potassium uptake.

III. Usage Methods

1. Basal Application: Spread fertilizer before planting, plow to incorporate. Ensures consistent potassium availability.
2. Topdressing: Apply during growth stages based on soil/plant needs. Use alone or blend with liquid fertilizers.
3. Foliar Spraying: Mist fertilizer solution onto leaves. Optimal for efficient potassium absorption.

IV. Precautions

1. Dosage Control: Excessive potassium may lead to overgrowth, reducing yield. Adjust amounts based on field conditions.
2. Timing: Apply during early-mid growth stages. Reduce usage later to avoid overstimulation.
3. Balanced Fertilization: Combine with nitrogen, phosphorus, etc., for comprehensive nutrient supply.
4. Soil Testing: Test soil before use to determine potassium levels and optimize application.
5. Environmental Protection: Prevent runoff to avoid groundwater/environmental contamination.

garlic potassium fertilizer is crucial for enhancing growth, yield, and quality. Follow proper usage and precautions to ensure efficacy and safety.
