1、Comparative Effects of Nitrogen Fertigation and Granular Fertilizer

This study therefore compared the GHG footprint and productivity of ‘papaccella’ pepper under two nitrogen fertilization methods: granular fertilization versus low-frequency fertigation with urea, each supplying about 63 kg N ha−1.

2、Effects of biofertilizer on the production of bell pepper

According to investigations, more than 1500 kg/ha of macro fertilizers, including N (nitrogen), P (phosphorus as P2 O 5), and K (potassium as K 2O), are utilized, with consumption amounts reaching 547 kg/ha of nitrogen, 840 kg/ha of potassium, and 145 kg/ha of phosphorus, respectively.

3、Optimization of water and nitrogen management for greenhouse green

Moderate water deficits favor peppers' yield and quality, while excessive nitrogen application reduces peppers' quality and yield. Reducing irrigation and rational fertilization could increase WUE, and controlling irrigation and reducing N fertilization would increase NUE.

4、The Effect of Nitrogen Fertilization on Yield and Quality of Bell Peppers

Bell Peppers are grown for fresh and processing markets in CA. Some growers use poles and black plastic mulched beds with drip irrigation and harvest several times per season ...

5、Optimisation of the amount of nitrogen enhances quality and yield of pepper

The goals of this study were to explore the characteristics of nitrogen (N) absorption and utilisation of chilli peppers (Capsicum annuum L.), improve the utilisation rate of nitrogen, and...

Assessing Nitrogen Fertilization in Processing Pepper: Critical

In summary, there is an urgent need to contrast efficient methods of irrigation and N management that are successful in open-field vegetables in terms of reducing water and N losses and thereby minimizing surface and groundwater pollution, whilst at the same time maintaining crop yield.

Effects of optimized fertilizer and water management on nutrient uptake

This study aimed to investigate the absorption, allocation, and translocation patterns of nitrogen, phosphorus, potassium, and secondary and micronutrients in different pepper organs at various growth stages, and to compare the effects of optimized integrated water-fertilizer management with conventional farmer practices and optimized ...

Responses of yield, quality and water

The results showed that above-ground dry matter accumulation (DMA), yield, harvest index (HI), and water use efficiency (WUE) of sweet pepper increased first and then decreased with the increase of irrigation/nitrogen amounts under the same nitrogen/irrigation levels.

Evaluation of Agronomic and Economic Effects of Nitrogen and Phosphorus

Drip fertigation is an effective way in splitting soluble fertilizer application to simultaneously meet water and nutrient demands of multi-harvested green pepper (Capsicum annuum L.). However, fruit yield and the profitability of green pepper can be constrained, if nutrients are either insufficiently or excessively supplied.

The key mechanism of improving nitrogen fertilizer utilization in

Due to the differences in nitrogen requirements of crops at different stages of growth and development, the uptake and utilization of nitrogen fertilizer by various organs of crops can explain the conversion of nitrogen into dry matter, reflecting different needs of crop growth stages.

There are several methods for applying nitrogen fertilizer to peppers, each with its own advantages and disadvantages.

1. Base Fertilization: This involves mixing high-nitrogen organic fertilizers (e.g., chicken manure, cow dung) thoroughly with soil during land preparation.

   • Advantages: Provides prolonged nitrogen release, benefiting pepper growth and development.
   • Disadvantages: Excessive nitrogen in organic fertilizers may cause rapid ammonia volatilization, leading to seedling damage. Additionally, this method requires large quantities of organic materials, increasing costs.

2. Topdressing: Nitrogen is applied periodically during the pepper’s growth cycle based on plant needs and soil fertility. Both synthetic fertilizers (e.g., urea, potassium nitrate) and organic options (e.g., composted farmyard manure, green manure) can be used.

   • Advantages: Timely replenishment of nitrogen to promote growth.
   • Disadvantages: Excessive or delayed topdressing may cause excessive vegetative growth, reducing yield. Environmental factors and fertilizer efficiency must also be considered to avoid pollution.

3. Foliar Spraying: Nitrogen-containing solutions or fertilizers are sprayed directly onto pepper leaves.

   • Advantages: Rapidly supplements nitrogen, accelerating growth.
   • Disadvantages: Improper spraying techniques or unsuitable formulations may harm plants. Concentration and application methods require careful control to prevent fertility burn.

4. Soil Application: High-nitrogen synthetic fertilizers are incorporated into the soil, relying on gradual nutrient release through adsorption and diffusion.

   • Advantages: Ensures steady nitrogen supply for growth.
   • Disadvantages: Slow-acting results, influenced by soil type and fertilizer composition. Environmental impact and efficiency must be managed to minimize pollution.

the choice of nitrogen application method depends on specific cultivation conditions and priorities. Careful consideration of fertilizer type, dosage, application timing, and environmental factors is critical to ensure effectiveness and safety.
