1、Combined effects of nitrogen fertilizer and biochar on the growth

The following hypotheses were proposed: (i) the combined application of biochar and nitrogen fertilizers increased the yield of pepper by enhancing root activity, superoxide dismutase (SOD) activity, chlorophyll content, and enzyme activity.

2、Effects of Biochar Combined with Nitrogen Fertilizer Application on

In agricultural systems, excessive application of nitrogen fertilizer often leads to low nitrogen use efficiency and environmental pollution. In order to solve this problem, we studied the synergistic effect of biochar and nitrogen fertilizer on pepper yield, quality and rhizosphere soil health.

Therefore, this field experiment was conducted to evaluate the effects of organic eco-green and inorganic nitrogen fertilizer on the growth and green pod yield of hot pepper during the...

Pepper Stip Trial #1

Red peppers are notably less firm than mature-green peppers. There were significant differences in final red color of the peppers: peppers from the higher N treatments developed the reddest color (lower hue value). Also percent weight loss in peppers in storage was substantially lower in red peppers than in mature-green peppers.

Effects of eco

Therefore, this field experiment was conducted to evaluate the effects of organic eco-green and inorganic nitrogen fertilizer on the growth and green pod yield of hot pepper during the growing season of 2019/2020.

Do Peppers Need a Lot of Nitrogen? (5 Ways to Provide it)

Peppers need a lot of nitrogen early in the season, so they can produce lots of green growth (stems and leaves). This green growth will create energy for fruit production later in the season. However, apply only a small amount of nitrogen fertilizer after pepper plants start to set fruit.

How do nitrogen levels affect growth and yield in bell pepper plants?

However, excessive N fertilizer is often applied to boost productivity but can instead reduce efficiency and cause nitrate leaching, leading to underground water pollution.

Effect of Nitrogen Fertilizer on Capsaicinoids and Related Metabolic

This study aims to elucidate the impact of nitrogen fertilizer on capsaicin accumulation and to provide guidance on fertilizer application on highly spicy chili peppers.

Nitrogen fertilizer is a commonly used nutrient in agricultural production, primarily functioning to provide essential nutrition for plants and promote their growth. its application also poses certain risks, one of which is the potential to induce regreening (the phenomenon of plants reverting to a green, vegetative state after flowering or maturation). Below is a detailed explanation of how nitrogen fertilizer can lead to regreening in red peppers:

1. The Principle of Nitrogen Fertilizer Action

Nitrogen fertilizer supplies nitrogen, a critical nutrient for plant growth. Nitrogen plays a key role in physiological processes such as photosynthesis, protein synthesis, and chlorophyll production. When applied in appropriate amounts, it enhances plant growth and increases yields.

2. Impact of Nitrogen Fertilizer on Plant Growth

Under optimal conditions, nitrogen fertilizer effectively stimulates plant growth, leading to vigorous development. excessive or improper use of nitrogen can disrupt this balance. Overabundance of nitrogen accelerates plant growth, enlarges leaf areas, and boosts chlorophyll content. This rapid growth may prematurely delay flowering or fruiting stages, resulting in regreening.

3. Link Between Nitrogen Fertilizer and Red Pepper Regreening

Red peppers, as light-loving crops, require ample sunlight and nutrients during growth. Excessive or mistimed nitrogen application can trigger regreening. Over-fertilization forces red peppers into early flowering and accelerated maturation, causing plants to revert to a green, vegetative state prematurely.

4. Possible Reasons for Nitrogen-Induced Regreening

(1) Excessive Nitrogen Application

Overapplication of nitrogen leads to surplus nitrogen accumulation in plants, disrupting normal physiological processes. High nitrogen levels may prematurely trigger flowering, followed by regreening.

(2) Improper Fertilization Timing

Applying nitrogen too late in the growth cycle or using incorrect methods (e.g., heavy surface spreading) can elevate nitrogen uptake, destabilizing the plant’s developmental stages.

(3) Other Contributing Factors

Climate fluctuations, pests, or diseases may also stress red peppers, weakening their ability to transition smoothly from flowering to maturation.

5. Prevention and Control Measures

To mitigate regreening in red peppers, adopt the following strategies:

(1) Rational Fertilization

Tailor nitrogen application based on soil fertility and red pepper nutritional needs, avoiding overuse.

(2) Timely Top-Dressing

Adjust nitrogen supplementation according to plant growth stages and soil conditions to meet specific requirements.

(3) Optimize Sowing Timing

Align planting schedules with climate and soil conditions to prevent premature or delayed growth.

(4) Enhance Management

Strengthen pest/disease control, protect foliage, and ensure healthy plant development.

while nitrogen fertilizer can indeed cause regreening in red peppers, this phenomenon can be effectively prevented and controlled through rational fertilization practices and proper management measures.
