Sow potatoes

Plant the potato

If you want to reproduce particular varieties, it is from January that the tubers stored from autumn will have to be put in a vegetative state. But in general, it is possible to buy pre-terminated seeds sold in boxes on the market. A clearly visible germ will indicate the right time for planting. The seedlings are quite fragile. It is therefore necessary to take into account the late frosts and plant the potato from mid-February in the South, to mid-April in the North. The potato loves deep and rich soils. A supply of compost or manure in winter and good soil tillage are effective. It will be planted on lines 40 to 50 cm apart, digging a groove of about 15 cm. deep, with a hoe. The potatoes should be placed at the bottom of the furrow, with the germ turned upwards, spacing them 30 cm apart. Then everything will be covered, with fine earth. When the jets come out of the ground and reach 15 cm., It will be necessary to tuck up the earth. This will facilitate the flow of rainwater and irrigation. It will also stimulate the formation of tubers avoiding their greening. The first harvests are at the end of May and extend until October for the late varieties.

Water the potato


The potato does not require a hot climate, but it does require rapid, regular growth, with good root development. These are rather superficial. For watering, it is necessary to wait for the soil to warm up, especially for clayey soils. Excess water damages the potato. At the end of winter, the soil generally has a good water capacity, sufficient to allow proper plant growth. Watering is only required in the case of a very dry spring, especially if a wet winter follows. Particular care should be taken not to wet the leaves, as this could promote fungal diseases. Water at room temperature and not too calcareous will be used, preferably through a pipe for irrigation of the furrows. A good mulch will give a better yield.

Choose your fertilizer well


The choice of fertilizer is important to optimize the crop. The addition of certain additives to traditional nitrogen fertilizers could limit losses during growth, with environmental and economic benefits. The determination of the dose of fertilizer to be administered is based on the nitrogen balance method and on procedures defined for phosphorus and potassium. Beyond these values, the choice of the form of fattening is particularly important to optimize the quantitative and qualitative production objectives. After intake, the nitrogen in the fertilizer is subjected to various processes. Absorption by the crop is hindered by different negative phenomena: leaching of nitric nitrogen as a result of drainage, gaseous losses through volatilization, organization of the internal soil organic matter. To facilitate absorption, it is necessary to focus on practices that minimize these losses, such as fractionation, which allows you to adjust the supplies according to the dynamics of the needs of the crop, or the choice of the form of fertilizer. The main fertilizers used are ammonium nitrate and nitrogen solution.

Planting Potatoes: Potato Exposure and Diseases


The potato requires a sunny exposure to develop well. It is subject to certain diseases and parasites to which attention must be paid, acting quickly with the treatment. Due to the aphids, which can be identified on the leaves, the fronds curl and lose their original color, showing a clear pinpoint. Mold causes oily brown spots that form on the foliage, affecting the potatoes themselves. The dorifera is the main threat from insects. It has black and white lines, while the larvae are orange. Its presence is recognized by the leaves eaten, sometimes entirely. Other dangers are bacterial rot, which causes lack of growth or its delay, the miner of the potato, which attacks the tuber as it does with the tomato, managing to kill 100% of the crop.
