1、Effects of Silicon

In this study, an application of Si fertilizer caused a higher Si uptake in rice biomass (grain + straw) over the control. The deficiency or sufficiency of Si in soil is primarily determined by the rate of its replenishment in soil solution and its uptake during plant growth.

2、Foliar and time of application of silicon and the effect on rice yield

The objective of the present work was to evaluate the foliar application times of different silicon sources on yield components, productivity and seed quality of irrigated rice.

3、When To Apply Foliar Fertilizer In Rice

Key points for applying foliar fertilizers in rice: Apply during critical growth stages, particularly panicle initiation and flowering. Ensure plants are fully turgid before spraying, and avoid hot, dry conditions. Late evening or early morning is the ideal time for application.

4、When to Apply Foliar Fertilizer in Rice? Boosting Crop Yield

A: The optimal timing for foliar fertilizer application in rice depends on various factors, including crop growth stage, soil type, and environmental conditions.

By foliar application, SiO 2 NPs, in the right concentration range, could promote plant immunity to improve rice’s resistance against the rice blast fungus.

Effect of Foliar Application of Silicon on Yield and Quality of Rice

A field experiment was conducted at University of Agriculture, Faisalabad, Pakistan, to investigate the effect of foliar application of silicon on yield and quality of fine rice (Oryza...

Effects of foliar silicon fertilizer application at different stages

The results showed that spraying foliar silicon fertilizer during the seedling, jointing, and full heading stages in rice production could promote rice yield and income increase, and improve the quality of rice to varying degrees.

Effects of Silicon Fertilizer Applied at Different Stages on Grain

The aims of this study were to identify the effects of silicon fertilizer applied at different stages on yield and quality of rice, and to provide theoretical basis and technical support for rational application of silicon fertilizer on japonica rice cultivar with good eating quality.

Experiments, Uptake Mechanisms, and Functioning of Silicon Foliar

In the present review, the effects of Si foliar fertilization, including nano-Si fertilizers, on the three most important crops on a global scale, that is, maize, rice, and wheat, are summarized.

Silicon Fertilizer Application Promotes Phytolith Accumulation in Rice

In this study, a pot experiment was designed to elucidate the effect of varying dosages of silicon (Si) fertilizer application in Si-deficient and enriched paddy soils on rice phytolith and carbon (C) bio-sequestration within phytoliths (PhytOC).

The best periods for foliar applying silicon fertilizer to rice are closely linked to the crop's growth and development stages. Silicon is an essential microelement in plants, playing critical physiological roles such as promoting root development, enhancing disease resistance, and improving photosynthetic efficiency. Below is a detailed analysis:

1. Seedling Stage

   • During the seedling stage (from seed germination to tillering), applying silicon fertilizer stimulates root growth and extension, strengthening the root system's ability to absorb water and nutrients, thereby ensuring robust early growth.
   • Early silicon application also helps prevent root diseases caused by soil acidification, such as root rot.

2. Tillering Stage

   • As rice enters the tillering phase (development of multiple stems from a single plant), silicon fertilizer reinforces stem strength, reducing the risk of lodging (plant collapse).
   • It additionally boosts photosynthetic efficiency, increasing the accumulation of photosynthates and contributing to higher yields.

3. Jointing and Booting Stage

   • During the transition from tillering to booting (formation of panicles), silicon application promotes stem maturation, enhancing stress resistance (e.g., cold tolerance, drought resistance).
   • Silicon also supports grain formation and filling, improving grain-setting rates.

4. Maturity Stage

   • In the maturity stage (from heading to full ripeness), silicon fertilizer improves grain quality, nutritional value, and market appeal.
   • Proper use extends the crop's lifespan, strengthens disease resistance, and reduces pest/disease incidence.

5. Key Considerations

   • Timing and Method: Apply silicon fertilizer during tillering, jointing-booting, and maturity stages. Adjust timing based on local climate and soil conditions. Use foliar spraying (direct application to leaves) or soil drenching (dilute fertilizer in water and spread evenly).
   • Avoid Overapplication: Excessive silicon may cause excessive vegetative growth, negatively impacting yield and quality. Determine optimal dosages via soil tests and rice variety characteristics.

The most effective periods for silicon application are during tillering, jointing-booting, and maturity stages. Proper use enhances rice growth, yield, and quality. Prioritize scientific timing, methods, and balanced application to ensure stable, high-quality production.
