Chili is a common vegetable crop with a spicy taste and rich nutritional value. However, to achieve high yield and high quality, scientific fertilization is essential. This article will introduce the relevant knowledge about what is the best fertilizer for chili.

Different growth stages require different fertilizers
The growth period of chili is generally divided into three stages: seedling, growth, and maturity. The nutrient requirements differ in each stage. The seedling stage requires potassium fertilizer to promote root growth. The growth stage requires large amounts of nitrogen, phosphorus, and potassium fertilizers to meet the needs of rapid growth. The maturity stage requires smaller amounts of nitrogen, phosphorus, and potassium fertilizers.
Choice of Organic and Chemical Fertilizers
Both organic and chemical fertilizers can be used for chili, but organic fertilizers are more suitable for long-term cultivation. For growers who need to quickly increase yield and quality, chemical fertilizers are also a good option.

Types of Organic Fertilizers
Organic fertilizers include livestock and poultry manure, bean cake, charcoal, rapeseed meal, etc., all of which have good water and fertilizer retention properties. However, when applying organic fertilizers, it is important not to use fresh manure directly, as it can burn the plants.
Classification of Chemical Fertilizers
Chemical fertilizers come in various types, such as nitrogen, phosphorus, and potassium fertilizers. Different types have different requirements for the various growth stages of chili. When applying chemical fertilizers, it is necessary to select the appropriate type based on the chili's growth stage.
Symptoms of Nutrient Deficiency and Remedial Measures
A lack of nitrogen causes leaves to turn yellow and slows plant growth. A lack of phosphorus leads to poor root development, affecting flowering and fruiting. A lack of potassium causes leaves to yellow and chili fruits to become deformed. The remedy is to promptly supplement the missing nutrients.

Reasonable Application Amount
A reasonable amount of fertilizer can promote rapid growth of chili, but excessive application can cause problems like soil acidification and nutrient leaching. The amount of fertilizer should be managed reasonably based on factors such as soil fertility and the chili's growth stage.
Coordination of Fertilizer and Water
The combination of fertilizer and water should be appropriate and moderate. Excessive water can lead to fertilizer loss, affecting the plant's absorption and utilization, which in turn impacts growth and development.
Reasonable Fertilization Time
Applying fertilizer at the right time is also crucial for the yield and quality of chili. During the growth stage, it is necessary to apply fertilizer in several installments to ensure the plant fully absorbs nutrients.
Fertilization Techniques
When applying fertilizer, ensure it is spread evenly and not piled up, as this can burn the plants. The fertilizer should also be applied deep into the soil to prevent it from volatilizing after being exposed to the sun.
Make Good Use of Compost
Compost is an organic fertilizer made from fermented organic waste. It is rich in nutrients and can be used as an organic fertilizer for chili. It can also improve soil structure and increase soil fertility.
Use of Microbial Fertilizers
Microbial fertilizers are a new type of organic fertilizer that promotes plant growth and enhances disease resistance. The proper use of microbial fertilizers can increase the yield and quality of chili.
Regularly Change Fertilizers
On land where chili is grown continuously, different crops have different nutrient requirements. Therefore, it is necessary to change fertilizers regularly to meet the growth needs of different crops.
Choice of Fertilization Time
Fertilization should be done in the morning or afternoon to avoid direct sunlight at noon, ensuring the maximum absorption and utilization rate of the fertilizer.
Make Good Use of Waste as Fertilizer
Waste can not only reduce environmental pollution but also its organic components can be used as fertilizer for chili. Materials like straw and sawdust are good fertilizer choices.
Scientific fertilization is key to increasing the yield and quality of chili. When fertilizing, it is important to select the appropriate type and amount of fertilizer according to the needs of different growth stages. At the same time, attention should be paid to factors such as fertilization time and techniques. Through scientific fertilization, we can grow a bountiful harvest of chili.
