Onions are a useful and essential vegetable in cooking. The simplest and most common way to obtain it, both in the form of greens and in the form of a turnip onion, is to grow from seedlings. But in order for the crop to be rich and healthy, it is necessary to carefully fulfill the requirements of agricultural technology, including the correct feeding of plants.
Top dressing of onion sets in the open field
The first feeding is carried out two weeks after planting the seedlings, when the feather growth is 10-15 cm. It includes a large amount of nitrogen-containing fertilizers, since at this stage it is important to ensure the growth of the green mass of plants, but at the same time, an excess of nitrogen can lead to a delay in the formation of bulbs, which will subsequently affect their size.
You can feed it with both organic fertilizers and mineral mixtures diluted in water. Here are some nitrogen-rich feeding options, all formulations are designed for 10 liters of water:
- 1 tbsp. mullein and 1 tbsp. l. urea;
- 8 tsp ammonium nitrate, 7 tsp. superphosphate, 5 tsp. potassium chloride;
- 2 tbsp. l. mineral complex for onions "Agricola" plus 1 tbsp. l. urea;
- 3 tbsp. l. ammonia.
Application rate: 2 - 2.5 l / m2.
The rate of watering with liquid top dressing with Agricola can be increased to 4 l / sq. m
Onions should not be watered with cold water, otherwise it may go into the arrows and the bulb will not form, but too warm water (above 18 ° C) is also not recommended, as it provokes the spread of powdery mildew.

The second feeding is carried out three weeks after the first. The fertilizers applied must necessarily have an increased content of phosphorus and potassium, since these substances affect the growth of the bulb, the proportion of nitrogen decreases... For this purpose, you can use the following recipes for liquid feeding (for 10 liters of water):
- 2 tbsp. l. ammonium nitrate, 4 tbsp. l. superphosphate, 2 tbsp. l. potassium chloride:
- 1 st. l. table salt and ammonium nitrate, 10 gr. one percent iodine;
- 2 tbsp. l. nitrophoski;
- 2 tbsp fertilizers "Agricol".
You can make a liquid herbal dressing: the third part of the bucket is tamped with a green mass of weeds (nettle is especially good). Add 3 liters of water and 1 tbsp to the bucket. l. yeast. After three days, the infusion is ready, it is diluted with water in a ratio of 1: 3 and used for feeding onions.
The third top dressing is done only if the onion is grown in poor lands. It is carried out three weeks before harvesting. To do this, you can use one of the proposed formulations, designed for 10 liters of water;
- 30 g of potassium chloride and 60 g of superphosphate;
- 2 tbsp. l. superphosphate;
- 10 g of potassium salt and 20 g of superphosphate;
- 2 tbsp. l. biological preparation "Effekton-O", 1 tbsp. l. superphosphate.
In addition to saturating the soil with minerals, Effekton accelerates the decomposition of pesticides in the soil and contributes to its saturation with carbon dioxide
As a top dressing, you can also use an infusion of wood ash: 250 gr. dissolve in 10 liters of boiling water and leave for 2 days. The beds are watered with this infusion.

When watering with fertilizer solutions, it is necessary to avoid getting liquid on the onion in order to avoid burning the plants.

If onion sets are planted only for greens, this bed is fertilized once. The timing and rates of application of minerals are the same as for the first feeding of onions on a turnip.
How to feed onion sets with yeast
Many gardeners, when growing vegetables for their families, do not want to use chemical fertilizers. The use of yeast for feeding onions allows you to get a good harvest without chemicals.
Benefits of using a supplement with yeast:
- the fertilizer contains minerals necessary for the growth and development of plants: nitrogen, potassium, phosphorus;
- it strengthens the immune system of plants, prevents the spread of fungal diseases;
- the structure of the soil and its saturation with air increase.
When using yeast feeding, you need to remember that fungal bacteria live at a temperature of at least twenty degrees. Folk remedies based on yeast are effective only in warm weather.
Recipes for preparing liquid solutions for feeding onions (only warm water is used):
- 10 g of dry yeast is diluted in 10 l of water and 50 g of sugar are added. The solution costs two days, then it can be used by diluting with water in a ratio of 1: 5.
- 10 g of granulated yeast, 50 g of sugar, 200 g of ash are poured into a container with 10 liters of water. The solution is ready in three days, it is diluted with water 1:10.
- A green grass mass is placed in the tank and filled with warm water. The fermentation process is maintained for a week, stirring the solution periodically. Then add 0.5 kg of raw yeast and leave for three more days. For watering, it is also diluted in a ratio of 1:10.

The choice of recipes for feeding onions is large, what exactly to stop at depends on the capabilities of each gardener. But you can get a decent harvest only by making efforts.
