Watering potatoes in open ground: features and timing
Potato is a fairly moisture-loving plant. In a very short time, he can grow not only large green stems, but also a couple of kilograms of tubers. Therefore, it requires a large amount of nutrients that the potato takes from the top layer of the earth. Timely proper watering, as well as compliance with the rules of cultivation, are of decisive importance in the maturation of a bountiful harvest of this root crop.
Does the crop need to be watered?
Often the owners of the beds wonder if it is necessary to water the potatoes in the open field, or is there enough rain to ensure a good harvest. Experienced gardeners who devote a lot of time to their beds believe that they need to be watered. This is especially true in those periods when there is no rain for a long time. Some regions suffer from strong winds that deprive the land of moisture. In this scenario, potatoes need to be watered every 5 days.
If the plant does not receive proper moisture at the initial stage of growth, then this will affect the number of tubers under the bush. Therefore, watering is very important for potatoes, especially in spring. But there are also gardeners who assure that it is not worth watering the potatoes - it is simply a waste of time. They claim that their harvest is no worse than that of those who regularly spend time watering vegetables.
Differences in the irrigation regime often depend on the quality of the land allocated for potatoes.If the earth is quite dense and heavy, then the humidity in it will already be increased, especially during periods of rain. Such a plot should not be watered, in which case the crop will be saved by frequent weeding, which will loosen the earth and give the plant more oxygen.
In cases where the land is sandy and there was very little rainfall, watering must be done throughout the entire period of potato growth. After all, sand dries out very quickly, and without irrigation, potatoes will not give a proper harvest.
It is worth considering in more detail what watering potatoes will give at a certain time:
- when the potatoes are just starting to grow, watering ensures good growth of the stems;
- watering potatoes during its flowering period will make it possible to obtain a greater number of high-quality tubers;
- the rest of the time, the hours devoted to watering will ensure a rich harvest, and the potatoes will turn out to be large.
When and how often should you moisturize?
Tubers with seedlings in most regions are planted in May, when the soil warms up to 10 C and contains enough moisture. Until small leaves appear above the ground, the vegetable does not really need artificial moisture. Especially if the potatoes were planted in moist soil. However, when the plant begins to develop, the need for water will increase greatly. Therefore, it is worth considering in more detail when and how often it is necessary to irrigate potatoes during the season.
The first time the owners water the potatoes when the stems have risen about 10 cm above the soil. It is necessary to water the plant directly in the middle of the bush. This process must be divided into several stages. First you need to pour a small part of the water under the bush and wait a bit for it to be absorbed. Then you need to add the rest of the liquid.This is done so that the earth is moistened evenly, and the potatoes are not flooded. If watering is done earlier, then this will provoke the development of the root system above the surface.
Subsequently, such plants not only experience a constant lack of moisture, but also develop poorly.
If we compare the early and late varieties of potatoes, then the first of them require much less water, but they use it more intensively. Therefore, it is necessary to ensure that the soil does not dry out. To find out when you need to moisten the soil, you can simply dip your hand into the ground to the depth of your fingers. If the soil is dry, then it requires watering. As the plant develops, it will consume more water. The amount of liquid needed for watering one seedling can be up to 6 liters. Since part of it evaporates into the air, in the heat each bush should receive up to 12 liters of water.
It is very important to water the soil during the formation of tubers. This happens during the flowering of potatoes. However, it is not worth waiting for the mass appearance of flowers, it is better to irrigate already at the birth of the first buds. This will increase the yield by about 30%. The timing of the next watering is associated with the growth of young tubers. This process begins after the flowering itself ends, and ends during the withering of the tops. Each bush should receive at least 20 liters of water - this is the amount of moisture that can wet the layer of earth.
Early varieties of potatoes grow quite quickly, so spring watering is best suited for them. After all, the lack of water during this period can lead to a decrease in the abundance of the crop. If there is not enough time for watering, then mulching can be done, which will not allow moisture to evaporate from the ground too quickly.
Ways
There are two types of watering: mechanical and manual watering. But some gardeners also call "dry" watering the work of loosening and hilling this crop. After all, this process helps moisture to be retained in the ground much longer. In addition, these works saturate the plant itself with oxygen. "Dry" watering or ordinary weeding begins almost after the appearance of the first shoots.
The earth between the rows is loosened after each irrigation of the earth. When the sprouts reach a height of 10 cm, each individual potato bush is spudded. For the harvest to be rich, these processes must be repeated three times. This must be done before the first flowers appear. Hilling should be done carefully so as not to injure the tubers that have already appeared. It is recommended to water the potatoes early in the morning or late in the evening. Fluid is applied through the furrows, with a hose or with drip irrigation.
Mechanical
Such irrigation includes both drip irrigation and sprinkler irrigation. The first delivers water directly to the root system of the vegetable. There is a special installation for irrigating the roots. This method is necessary for those gardeners who grow large volumes of potatoes, as well as for people who cannot lift weights and carry water.
Sprinkler irrigation systems are placed directly above the ground or are made in the form of networks that can be installed both above and below the ground. The first of them are perfect for irrigating potatoes before and after flowering. But during the flowering itself, it is impossible to water the potatoes in this way. This causes the pollen to be washed away and yields can plummet.
You also need to decide how large the drops of water will be.If they are too large, then the ground under the bush will become dense, and this is bad for potatoes. When using small drops, the soil may not receive water at all, since the liquid will remain on the leaves and stems and simply evaporate. In these cases, you need to loosen the earth as often as possible.
It is very convenient to use the grid. Thanks to this, water enters directly into the root system of the plant. In addition, this option is good because water does not compact the soil and does not form crusts on the surface. The only disadvantage of mechanical watering is the high cost of the installations themselves, as well as some additional equipment. Both water dispensers and timers are expensive.
Manually
This method is quite simple and familiar to almost everyone. Potatoes are watered using watering cans or simple hoses, which are brought to each bush separately. The advantage of manual watering lies in the point impact on plants. In this case, you can water only those bushes that require it the most. But this option is suitable only for very small those areas, because watering a large area will take too much time if everything is done manually.
You need to water gradually. First, a liter of water is poured directly under the root, and then, when the moisture is completely absorbed, you can re-water. One bush will be saturated with moisture 4 liters of water. In general, such a process is not particularly difficult, but with a hose it will be much easier to do. In order not to blur the ground around the bush, you need to put a small sprayer on the end of the hose.
First, a certain row or square of land is watered, and then the next sector. Then you need to return to the first row and repeat the procedure. This is necessary so that the earth is well moistened.
Basic Rules
It is important to know the following.
- Having decided to grow potatoes on your own plot, you need to familiarize yourself with the basic rules for watering it.
- It is better to irrigate the plant with water heated in the sun. After all, potatoes are a plant of the nightshade family, which means that it has rather tender roots. When ice water hits them, the rhizome gradually rots.
- It will be correct to start watering when sprouts up to 10 cm in size appear above the ground.
- When planting, potatoes must be protected from excess moisture, as part of it can simply rot. Therefore, at first, this plant is better not to be watered.
- Do not forget about the most important periods when you need to irrigate the land. First of all, this is the budding of the plant. At this stage, each bush needs about 5 liters of water. Watering is recommended twice a week. After the flowers have completely fallen off, you can water the plants less often - once a week will already be enough. Gradually, it is worth reducing the amount of fluid used to 4 liters. And the last stage is watering the formed tubers. At this time, potatoes require a lot of water for growth and full development, and up to 6 liters can be poured under one bush.
- It is worth considering the climate and weather. In the heat, irrigation is done up to 6 times a month. When it rains, the number of waterings decreases to three, or even less, once a month.
Signs of excess and lack of moisture
Both the lack of moisture and its excess have a bad effect on all stages of potato growth and the final harvest. Therefore, it is worth paying special attention to monitor the condition of plants.
When a plant lacks moisture, this can be determined by the following signs:
- the turgor of stems and leaves decreases, they become lethargic and drooping, and also brighten a little;
- the growth of the stems stops, and the buds that have already formed do not open;
- small undeveloped stems completely die off.
Excess moisture in the soil most often leads to the attack of potatoes by various fungal diseases and rotting of the root system. All this can be defined as follows:
- leaves become drooping and slightly watery;
- spots may appear at the bottom of the stems, and in some cases a plaque forms;
- potatoes do not grow, most tubers begin to rot.
To prevent this from happening, you need to carefully monitor the plants. In cases where there is not enough moisture, it is necessary to irrigate the potatoes. If there is a lot of moisture, then it is necessary to thin out the bushes a little so that the plant can "ventilate". As can be seen from the above, potatoes need regular watering. But for the most part, this applies to those regions where the summer does not indulge the beds with rain. If in such an area you properly care for the plants and water them regularly, they will remain healthy and delight gardeners with a good harvest.
