1、Assessing the efficacy and residual impact of plant growth retardants

Lodging caused by overgrowth significantly reduces crop yields worldwide annually. Plant growth retardants (PGRts) as a chemical intervention widely adopted in agricultural practices provide an effective strategy to mitigate lodging and control excessive growth.

2、Corn growth and yield response to starter fertilizer in phosphorus

This study aimed to (i) investigate the impacts of starter fertilizer placement on corn growth, nutrient uptake, and grain yield in P-sufficient soils and (ii) determine whether the timing of planting influences corn response to starter fertilizer placement across different growing environments.

3、Frontiers

A three-cycle field experiment was conducted to investigate the underlying agronomic mechanism on modulating the root lodging resistance and yield stability of sweet corn in response to the planting density and nitrogen rate during different growth seasons.

4、Effects of Plant Growth Regulators and Nitrogen Management on Root

Lodging is one of the main factors causing yield loss of maize under high-density planting conditions. Root lodging as an important lodging type has received little attention. Plant growth regulators (PGRs) and nitrogen fertilizer can coordinate the relationship between root lodging and yield.

Optimized nitrogen and potassium fertilizers application increases stem

Results indicated that nitrogen and potassium fertilizer levels and their interactions promoted lignin accumulation, improved lodging resistance, and increased grain yield.

Split nitrogen management and high planting density exacerbate root

Base on these findings, we believed that split nitrogen management with dense planting can improve sweet corn lodging resistance and yield during summer growth seasons in tropical China, especially in Hainan Province (1200–1500 mm precipitation and 28–30℃average temperature in summer growth season) whose sweet corn production reach to 0. ...

Effects of nitrogen fertilizer and chemical regulation on spring maize

Chemical regulation and nitrogen fertilizer could effectively coordinate the relationship between stem lodging and maize yield, which significantly reduce lodging and improve the grain yield.

Management of nitrogen fertilization to balance reducing lodging risk

Few studies have been conducted to clarify the trade–off between grain yield and lodging resistance, and assess whether it is possible to manage lodging risk without a yield reduction penalty.

Effects of nitrogen fertilizer application rate on lodging resistance

Four japonica rice varieties with different lodging resistance were used, and six nitrogen fertilizer levels were set up to analyze the morphological structure, mechanical properties, and...

How to prevent corn lodging

If a large amount of nitrogen fertilizer is applied at this time, the growth of the stem segments will be accelerated and the risk of lodging will increase. Production generally does not advocate the application of nitrogen fertilizer at the jointing stage.

Corn lodging is a common issue in agricultural production. It not only affects corn growth and yield but may also lead to the occurrence and spread of diseases and pests. controlling corn lodging is one of the key measures to improve corn yield and quality. In practice, farmers often encounter situations where corn has lodged. So, can control-growth fertilizer still be applied after corn lodging? The following provides a detailed answer to this question.

First, it is essential to understand what control-growth fertilizer is. Control-growth fertilizer refers to fertilizers applied in appropriate amounts to regulate nutrient supply during crop growth, thereby controlling plant growth. For corn, such fertilizers effectively prevent lodging, enhance stress resistance, and boost yields.

when corn has already lodged, is it still possible to apply control-growth fertilizer? The answer is yes. In fact, timely application of control-growth fertilizer is critical for lodged corn plants. This is because lodged plants often suffer from root damage and reduced nutrient uptake, increasing their nutrient demands. Without timely replenishment, these plants may deteriorate further due to malnutrition, leading to persistent lodging or even death.

Thus, for lodged corn, applying control-growth fertilizer as soon as possible is recommended. The specific dosage and method should be adjusted based on local climate, soil type, and corn growth stages. Generally, the application rate is 5–10 kilograms per mu (approx. 0.07–0.14 hectares), using methods like trench or hole application.

Key considerations during application:

1. Select appropriate fertilizers: Choose formulas rich in nitrogen, phosphorus, and potassium to promote recovery. Avoid fertilizers containing heavy metals or harmful substances to prevent secondary damage.

2. Timing matters: Apply control-growth fertilizer during early growth stages to ensure adequate nutrient absorption. If missed, a mid-growth application can still be beneficial.

3. Avoid overapplication: Excessive fertilizer may increase soil salinity, harming plants. Follow recommended dosages strictly.

4. Apply correctly: Use trench or hole methods to distribute fertilizer evenly around plants. Never sprinkle directly onto leaves to avoid burning.

5. Post-application management: Maintain soil moisture, remove weeds, and prevent diseases. These steps enhance plant resilience and reduce lodging risks.

lodged corn can still benefit from control-growth fertilizer. By following the above guidelines, plants can recover effectively, improving yield and quality. Beyond fertilizers, measures like optimal planting density and enhanced field management are equally important. Only through integrated practices can agricultural productivity be maximized.
