1、A recommended nitrogen application strategy for high crop yield and low

Through 9 years of field experiments, Dai et al. (2015) found that higher winter wheat yield could be obtained by controlling nitrogen fertilizer rate at 66–92 kg N/ha in the Loess Plateau.

2、Adaptation Strategies of Seedling Root Response to Nitrogen and

In this study, we conducted a 10-month experiment at the Castanopsis kawakamii Nature Reserve to evaluate the response of traits of seedling roots (such as specific root length, average diameter, nitrogen content, and phosphorus content) to nitrogen and phosphorus addition.

3、Effects of low nitrogen on seedling growth, photosynthetic

This study used hydroponics to compare the effects of three nitrogen supply levels (1N, 1/2N and 1/4N) on the antioxidant capacity of rice varieties JJ88 (nitrogen efficient) and XN999...

4、Seedling

In conclusion, a short-term and moderate DI regime—adopted at the seedling stage under higher initial SWC and coupled with an appropriate N fertilization—is beneficial to control redundant vegetative growth while optimizing root development, therefore effectively improving drought tolerance for maize plants and achieving higher grain yield ...

Effect of nitrogen, phosphorus and potassium fertilization management

We recommend that the optimum fertilization ratio of Sapindus mukorossi was 0.96Kg N, 0.80Kg P and 0.64Kg K per plant. Reasonable fertilization can improve soil fertility and leaf physiological traits, while excessive fertilization has negative effects on soil fertility, leaf physiology and yield.

Optimizing nitrogen application timing at key leaf stages to enhance

These results indicate that applying nitrogen at the eighth leaf stage could be an efective way to enhance productivity for high-density dry direct- seeded rice within the rice-wheat rotation system.

Optimizing Nitrogen Fertilizer Management Enhances Rice Yield

According to the regression equation, the yield is higher when the amount of nitrogen application is 202.15 kg ha −1 and the fertilization frequency is four times.

Fertilizing Bedding Plant Seedlings

Plug researchers have identified four stages of seedling growth and have developed guidelines for fertilizing each stage (Table 1). Fertility is not a critical factor for most species during Stage 1 because most seeds have enough stored nutrients to carry out germination.

Effects of nitrogen, phosphorus and potassium fertilization on the

A total of 14 treatments with “3414” experimental design was set up to explore the effects of formula fertilization with N, P and K three factors under four levels on the one year-old Q. gilva container seedlings.

Nitrogen fertilization application strategies improve yield of the rice

The results showed that N fertilization strategies could improve the nitrogen use efficiency and yield of rice, but the response of different rice varieties to N fertilizer strategies...

Siraitia grosvenorii, commonly known as Luo Han Guo, is a traditional Chinese medicinal herb and food processing ingredient native to mountainous regions in southern China. It is renowned for its effects in clearing heat, detoxifying, moistening the lungs, and relieving coughs, often used to treat symptoms such as excessive phlegm, sore throat, and persistent coughs. During the seedling stage of cultivation, proper nitrogen fertilization is critical to ensuring healthy growth. The following recommendations outline best practices for nitrogen application:

1. Selection and Application of Nitrogen Fertilizers

• Organic Fertilizers: Options like compost or well-decomposed manure provide a balanced source of nitrogen and other nutrients. They improve soil structure and organic matter content. Ensure thorough fermentation before use to prevent root damage.

• Urea: A high-nitrogen fertilizer suitable for promoting rapid seedling growth. Use with caution to avoid overapplication, which may cause root burning.

• Compound Fertilizers: Formulated with multiple nutrients, these can be customized based on soil test results and seedling needs. Apply evenly to prevent localized overconcentration.

2. Timing and Methods of Application

• Early Application: Apply moderate nitrogen within the first 30 days after sowing to support initial growth.

• Topdressing: As seedlings grow, apply nitrogen in regular intervals. Begin the first topdressing when plants reach 5–10 cm in height, then repeat every 7–10 days (or according to growth and soil conditions) until autumn.

• Deep Placement: Since seedling roots are shallow, apply fertilizers deeply to enhance absorption efficiency.

3. Key Considerations

• Avoid Overapplication: Excessive nitrogen can lead to rapid, unhealthy growth, reducing later quality and yield. Strictly control application rates.

• Soil Testing: Conduct soil analyses pre-application to determine nitrogen levels and pH, refining fertilization strategies accordingly.

• Nutrient Balance: Complement nitrogen with phosphorus, potassium, and other essential elements to ensure comprehensive nutrition.

Optimizing nitrogen fertilization is vital for robust seedling development. By selecting appropriate organic or synthetic fertilizers, timing applications correctly, and addressing key considerations, growers can enhance yields and quality. Balancing nitrogen with other nutrients guarantees full nutritional support for healthy plant growth.
