Optimal Timing for Potassium Fertilization in Sugar Beet

1、Cultivar specific nitrogen and potassium recommendations

This study aimed to investigate cultivar-specific responses to nitrogen and potassium fertilization in sugar beet (Beta vulgaris) to optimize yield, quality attributes, and fertilizer use...

2、Excessive Potassium Fertilization Reduces Sugar Distribution in

Potassium is vital for sugar crop growth, yet excessive application often limits yield and quality improvements in sugar beets. To determine the optimal type and application rate of potassium fertilizer for drip-irrigated sugar beets in lime soils, a field experiment was conducted in 2024. Two cultivars (KWS9899 and KWS7748) were treated with two potassium sources (KCl and K2S04) at four ...

Excessive Potassium Fertilization Reduces Sugar Distribution in

3、Sugar beet yield and industrial sugar contents improved by potassium

The results revealed that increase in the level of K fertilization at water sufficient level significantly increased plant growth, beet yield and industrial beet sugar content.

4、Sugarbeet fertilizer recommendations

Currently, we do not recommend the use of a starter fertilizer with potassium because there is little research on the effect these sources have on sugarbeet growth and only a small amount of the sugarbeet growing areas need potassium fertilization.

Potassium deficiency reduces sugar yield in sugar beet through

It is concluded that under overall low soil K conditions, adequate amounts of K fertilizer should be applied to meet the demand of sugar beet seedlings for maximum growth and final sugar yield. Banded K fertilizer application next to the plant rows is supposed to be efficient for this purpose.

Potassium and Magnesium Balance the Effect of Nitrogen on the

To determine the effects of these nutrients on beet yield (BY), quality parameters, white sugar yield (WSY), and nitrogen use efficiency (NUE) indices, a three-year field study was conducted in western Poland.

Effect of the Application Date of Fertilizer Containing Silicon and

In an experiment conducted in 2018–2020, the effect of the method of foliar fertilization containing silicon and potassium on the yield and technological quality of sugar beet roots was assessed. The fertilizer was used in seven combinations, differing in the number and time of application.

Fertilization Model of Nitrogen, Phosphorous and Potassium: Based on

Abstract: To explore the optimal fertilization model of nitrogen, phosphorus and potassium for high yield and good quality of sugar beet, we took sugar beet as the research object and adopted the field regression experiment, to study the relationship between N, P and K factors in sugar beet cultivation and yield and quality of sugar beet ...

Optimization of Potassium Fertilizer Rates Applied to Sugar Beet on

In cultivation of sugar beet, existing recommendations for the CFD stipulate a ratio of nitrogen fertilizers to potassium fertilizers in a.i. of 0.9 and 1.45 when cultivating sugar beet and corn, respectively.

Effect of the Application Date of Fertilizer Containing Silicon and

In an experiment conducted in 2018–2020, the effect of the method of foliar fertilization containing silicon and potassium on the yield and technological quality of sugar beet roots was...

Sugar beet, also known as Beta vulgaris, is a widely cultivated crop primarily used for producing natural sweetener—beet sugar. During cultivation, proper application of potassium fertilizer is crucial for improving the quality and yield of sugar beet. Regarding when to apply potassium fertilizer, the following recommendations are provided:

1. Growth Stage Division of Sugar Beet

  • Seed Germination Stage: This phase focuses on seed emergence and seedling growth. Applying potassium fertilizer here promotes root development and enhances the plant’s stress resistance.
  • Tillering Stage: As sugar beet begins tillering, it requires substantial nitrogen to support stem and leaf growth. Potassium aids in carbohydrate transport, boosting photosynthetic efficiency.
  • Bolting Stage: During flowering and bolting, potassium fertilizer facilitates the formation of floral organs and improves fruit quality.
  • Maturity Stage: This critical pre-harvest period sees potassium driving sugar accumulation, enhancing sugar content and quality.

2. Ideal Timing for Potassium Application

  • Before Sowing: Applying potassium before sowing encourages seed germination and establishes a strong foundation for growth.
  • Before Transplanting: Pre-transplant application strengthens roots and increases disease resistance.
  • Before Tillering: Applying potassium ahead of tillering supports robust stem and leaf growth, intensifying photosynthesis.
  • Before Bolting: Pre-bolting application ensures healthy floral development and superior fruit quality.
  • Before Maturity: A final potassium dose before maturity maximizes sugar accumulation, optimizing sweetness and quality.

3. Methods of Potassium Application

  • Basal Application: Spread potassium evenly on soil or in furrows, then deeply plow to integrate it thoroughly.
  • Topdressing: Apply timely topdressings during key growth stages (e.g., tillering, bolting).
  • Foliar Spraying: Supplement potassium through foliar sprays during growth to enhance photosynthetic efficiency.

4. Key Considerations

  • Avoid Overapplication: Excessive potassium can lead to soil salinization, reducing soil aeration and microbial activity. Control dosages strictly.
  • Combine with Nitrogen and Phosphorus: Synergistic use of nitrogen, phosphorus, and potassium fertilizers improves nutrient uptake and overall growth.
  • Soil-Specific Adjustments: Optimal potassium types and methods vary by soil conditions. Tailor choices to soil properties.

The best times to apply potassium to sugar beet are pre-sowing, pre-transplanting, pre-tillering, pre-bolting, and pre-maturity. Methods include basal, topdressing, and foliar applications. Prioritize balanced usage, soil health, and crop needs to maximize sugar beet quality and yield.
