Tomato cultivation

Irrigate tomatoes

Wet the tomato plant requires a lot of scrupulousness: if done roughly it causes irreversible damage and destructive diseases. The irrigation activity, in fact, allows for an increase in yields, but often affects the quality of the tomatoes. In the case of “salad” table tomato crops, it is advisable to irrigate lightly and frequently; less frequent and more abundant for industrial tomatoes, avoiding irrigation close to harvest, therefore well in advance. During the flowering phase, make sure that the plant is not deficient in irrigation, while, in the vegetative and ripening phase and with reduced water availability, the plant bears better the lack of water. There are various irrigation systems: let’s say in general that the rain one has the drawback of being able to cause bacterial or fungal cancer diseases; the more widespread lateral infiltration one or the droplet one, nowadays widespread, are to be preferred. The water requirement is about 400mm in a production cycle of around 120 days for the transplanted crop and 130/150 for the sown one.

Tomato cultivation


Herbaceous of the Solanaceae family, it develops in height between 0.7 and 2 meters and its roots from 0.7 to 1.5 meters. Where born on the spot we will have a strong root, rich in taproots and very branched, where a much less taproot root is transplanted. It belongs to the so-called renewal plants and its cultivation cycle requires an optimal rest period of around 3-4 years, allowing the soil to lose its important parasitic charge. Prepare the soil in the summer with a deep plowing, about 50cm, and subsequent refinements in autumn. In the case of clayey soils also prepare the seedbed. In the case of sowing, provide a rolling of the soil to allow the absorption of liquids, disfavouring possible chemical reactions, in the case of transplanting do not forget to irrigate immediately after so that it takes root well. Ensure good weeding activity, i.e. aerate the surface layer of the soil, to promote air circulation and sun penetration and control weeds. Possible good mulch. Provide supports for the plant and keep it clean at the root, freeing it from weeds. The activity called scacchiatura, or sissy is important: it involves manually and constantly eliminating the axillary shoots in order to obtain a balance between vegetation and fruits without dispersion of nourishment, channeling the sap towards the tomatoes.

How to fertilize, when to fertilize


The tomato plant should never lack nutritional elements. Its cultivation, although adaptable in general to any type of soil, certainly prefers soils rich in organic substances, well irrigated, draining and of medium grain size. How and when to fertilize is in relation to the soil, to the outdoor or greenhouse crop. Nitrogen, but also phosphorus and potassium, as well as calcium and magnesium are essential for the tomato, a plant with a long cycle, which absorbs nutrients in large quantities. In fact, it feeds voraciously on the nutrients present in the soil and in order to offer healthy and succulent fruits a preventive examination of the soil and its organic characteristics is necessary, integrating deficiencies also of a mineral nature. Pure manure or stalatic is an excellent fertilizer, indeed never as excellent in this case: the plant feeds on it in significant quantities, reaching up to 5-600 quintals per hectare, or 5-6 kg per square meter in the vegetable garden. Compost or manure are possible alternatives. The fertilization of the soil must also be carried out in a preventive form on the occasion of the deep preparation of the soil, before sowing or transplanting.

Exposure, diseases and possible remedies


Plant that requires a warm temperate climate and full sun. It should not be allocated below 12 ° C for its germination and 24-26 ° C during the day with 14-16 ° C at night to favor the swelling and ripening of the fruits. Attention both to high temperatures, that is over 30 ° C, and to high temperatures without nocturnal variance: defects in consistency, color or consolidation of the fruits can be generated immediately after flowering. It cannot stand freezing and is heavily damaged in humid environments, vehicles of disease and rot. Good ease of adaptation to different terrains, but it presents numerous pitfalls and parasites. First of all the physiological alterations: apical rot and cracking of the fruits. Damage resulting from water alterations in the first case and sudden excess water combined with subsequent stress in the second case. It is subject to aggression of terrestrial fungi that damage both the roots and the collar, or the basal part. It develops diseases of the aerial part of fungal or viral origin. Not least animal parasites. Drainage, crop rotation, soil disinfection and plant defense treatments where necessary.
