1、Lodging resistance locus prl5 improves physical strength of the lower plant part under different conditions of fertilization in rice (Oryza

High fertilizer application rates increase grain yield and biomass in rice, but reduces lodging resistance. Lodging resistance locus prl5 enhances pushing resistance through delaying leaf senescence and increasing carbohydrate reaccumulation in stems.

Based on the study results, a balanced nutrient application using NPK fertilization is a key management strategy for enhancing rice-rapeseed productivity and environmental safety.

3、Nitrogen fertilizer application affects lodging resistance by altering secondary cell wall synthesis in japonica rice

Stem mechanical strength is an important agricultural quantitative trait that is closely related to lodging resistance in rice, which is known to be reduced by fertilizer with higher levels of nitrogen.

4、Effect of N Fertilization Pattern on Rice Yield, N Use Efficiency and Fertilizer–N Fate in the Yangtze River Basin, China

The objectives of this research were to investigate the effect of different fertilization patterns (FFP and RZF) on rice yield, fertilizer—N diffusion kinetics, N uptake and NUE using the 15 N tracer technique in the Yangtze River basin, one of the main rice planting regions of China.

5、Lodging in rice can be alleviated by atmospheric CO

The objective of this research was to study the effects of interactions between elevated [CO 2] and N fertilization on lodging and the contribution of lodging to yield losses in rice in the field using a FACE system.

Effect of nitrogen root zone fertilization on rice yield, uptake and utilization of macronutrient in lower reaches of Yangtze River, China

Improper application of nitrogen (N) has led to high N losses and low N use efficiency in the lower reaches of Yangtze River in China. An effective method to solve such problems is the deep fertilized N in root zone (RZF). Limited information is available on the effect of RZF on the uptake of macronutrients (N, P and K) and rice yield.

A core technology implemented in those strategies to increase rice yield and nitrogen use efficiency is split fertilization, especially topdressing, applied during the panicle initiation...

Lodging Resistance of Japonica Rice

Lodging in rice production often limits grain yield and quality by breaking or bending stems. Excessive nitrogen (N) fertilizer rates are the cause of poor lodging resistance in rice, but little is known about the effect of top-dressing N application rates on the mechanical strength of japonica rice plants, especially how the anatomical ...

Reduced fertilizer usage is one of the objectives of field management in the pursuit of sustainable agriculture. Here, we report on shifts of bacterial communities in paddy rice ecosystems with low (LN), standard (SN), and high (HN) levels of N fertilizer application (0, 30, and 300 kg N ha −1, respectively).

Studies on the Lodging of Rice Plants

Lodging has long been recognized as a vital factor in growing rice plants and its importance has been greatly accentuated not only by the pos sibility of increasing yield through heavy fertilizer applications and dense planting, but also by the advent of cultivation of direct sowing and mechanical harvesters in recent years.

Preventing rice lodging is a critical measure for improving rice yield and quality. Rational fertilization strategies can significantly reduce the risk of rice lodging. The following recommendations are provided:

1. Apply Balanced Compound Fertilizers: During rice growth, balanced compound fertilizers should be applied regularly to ensure comprehensive nutrient supply. These fertilizers typically contain nitrogen (N), phosphorus (P), potassium (K), and microelements (e.g., iron, zinc), which are essential for rice development.

2. Use Organic Fertilizers: Organic fertilizers, such as farm manure and animal compost, enrich soil nutrients, improve soil structure, promote healthy root growth, and reduce lodging risks.

3. Opt for Controlled-Release Fertilizers: These slow-release fertilizers prevent nutrient loss and soil salinization caused by excessive applications, thereby lowering lodging potential.

4. Supplement Micronutrient Fertilizers: Trace elements like boron, manganese, copper, and molybdenum play vital roles in rice growth. Proper supplementation strengthens roots and enhances lodging resistance.

5. Incorporate Biofertilizers: Microbial fertilizers and green manures introduce beneficial organisms that promote soil ecological balance, fostering robust rice growth and reducing lodging risks.

6. Apply Chemicals Strategically: Avoid over-application of chemical fertilizers to prevent nutrient imbalance. Adjust fertilization plans based on growth stages and soil conditions for optimal nutrient equilibrium.

7. Utilize Foliar Fertilizers: Sprayed directly onto leaves, foliar fertilizers provide rapid nutrient absorption. Select formulations tailored to crop needs and environmental conditions for best results.

8. Apply Water-Soluble Fertilizers: These fertilizers, dissolved in water, enable quick nutrient uptake during top-dressing or irrigation, offering immediate replenishment for rice requirements.

9. Apply Diammonium Phosphate: This nitrogen-rich fertilizer promotes root development and stem elongation, reducing lodging when combined with other nutrients.

10. Employ Potassium Fertilizers: Potassium strengthens stems and roots, enhancing lodging resistance. Options like potassium sulfate or potassium chloride should be chosen based on soil and rice varieties.

11. Supplement Silicon Fertilizers: Silica improves root structure and function, boosting anti-lodging capabilities. Calcium silicate or similar silicon-based fertilizers are recommended.

12. Apply Calcium Fertilizers: Calcium increases stem strength and flexibility. Limestone powder, gypsum, or other calcium sources should be selected according to soil and rice types.

13. Use Magnesium Fertilizers: Magnesium supports root and stem growth. Epsom salt (magnesium sulfate) or magnesium oxide are suitable options.

14. Add Zinc Fertilizers: Zinc enhances disease resistance and stem stability. Zinc sulfate or zinc oxide are effective choices.

15. Apply Boron Fertilizers: Boron aids root and stem development. Sodium borate or boric acid can be used to reduce lodging.

fertilization should align with rice growth stages and soil conditions to avoid nutrient excesses or deficiencies. Employ efficient application methods (e.g., deep placement, band application, or ring application) to maximize fertilizer use. Additionally, integrate field management practices, such as timely irrigation, drainage, and pest control, to ensure healthy rice growth and minimize lodging risks.
