When growing tomatoes on an industrial scale, it is important that the variety is suitable for mechanized harvesting. One of these is the Rio Grande. The tomato variety has a number of advantages that are also appreciated among summer residents and owners of country houses.
Let's start with a description. The plant of determinant type with a vegetation period of 110-120 days is characterized by stress resistance and universal use of fruits. The height of the bush rarely exceeds 70 cm, so agricultural technology does not provide for a garter. A compact tomato with a moderate amount of foliage does not need pinching.
The fruiting period continues throughout the summer season. The fruit in the form of cream by the time of technical ripeness gains weight from 70 to 150 grams... The flesh of a beautiful red color has a dense structure, which makes the vegetable suitable for drying and drying. The crop is often used to make sauces and ketchups. The sweetish taste with a slight sourness is appreciated by culinary experts from many countries of the world.
The variety is the work of Dutch breeders. The crop is intended for cultivation in open ground and under cover (in greenhouses and greenhouses). The yield per bush is 4.5-5.8 kg.
In order to form an opinion about the Rio Grande variety, it is worth considering its advantageous characteristics. Among the main ones:
Tomato has no obvious drawbacks, although some gardeners note low juiciness. This fact is due to the dense structure of the pulp, which is appreciated in the production of ketchup and sauces.
The soil is selected with a light structure, fertile (a universal substrate or a mixture of turf soil with humus is suitable). Before sowing, the soil is warmed up in the oven or watered with a weak solution of potassium permanganate for disinfection.
When planting seeds in open ground, the garden bed is prepared in the fall, digging up and adding humus. In the spring, mineral fertilizers are used to enrich the soil with the necessary microelements... Holes are made under the seeds at a distance of 40 cm. Along the edges of the beds, boards from boards are installed, with the help of which the film is fixed as a shelter. After the formation of 2 pairs of leaves, the seedlings are transplanted into separate holes.
It is recommended to purchase seeds in specialized stores. This guarantees complete processing of the material, resistance to diseases and pests.
It is not necessary to carry out disinfection and soaking at home in order to stimulate growth.
When choosing grains, you should first familiarize yourself with the information on the label, which indicates the basic rules of agricultural technology, expiration date and other recommendations. After removing the grains from the packaging, healthy and large grains should be selected. If any lesions are found, culling is done.
When using the seedling method, sowing is planned for early or mid-March (60 days before planting seedlings in the garden).
For soil, use containers or wooden boxes that are at least 10 cm deep. Plastic cups and pots can also be used. The bottom of the container should have drainage holes to release excess moisture during watering.
On the surface of the soil, small depressions are made with a finger (no more than 2 cm) with an interval of 4-6 cm. 2 seeds are placed in each groove. From above, they are covered with a small layer of peat.
To create optimal conditions for seed germination, you need to spray the crops with warm water (in moderation), and cover the container with glass or film. The temperature regime before emergence should be 23-25 °. As soon as the seedlings appear, the container is placed in a well-lit place, the shelter is removed, and the temperature is lowered to 18-20 °. So that the sprouts do not stretch too much, it is better to lower the night indicator to 16 °.
With insufficient light, the seedlings will not develop normally, so you need to install additional lighting (fluorescent lamp) above the improvised bed.
After the formation of 2 leaves on the sprouts, the seedlings should be dived, that is, transplant each root into a separate container. 7-10 days before the transfer of seedlings to the garden bed, a hardening procedure is carried out for better adaptation in a new environment.
The transfer of seedlings to the greenhouse is carried out from mid-April to the 10th of May. Young shoots are planted in open ground from the 20th of May to mid-June. In the southern regions of the country, sowing directly into the open ground is practiced.
Plants are considered the best predecessors for the Rio Grande variety: herbs, legumes, cabbage, lettuce.
Tomatoes are planted in rows with an interval of 35-45 cm or in a square-nesting method according to a 40x50 cm scheme. The depth of the holes is 10-15 cm. No more than 6 shoots are placed per 1 m2. A mixture of peat, wood ash and humus is preliminarily poured into the recess, then the shoot is immersed.
The Rio Grande tomato is very easy to care for, even an inexperienced gardener can grow and take a good harvest. The basic rules of agricultural technology are in the following sections.
Do not overmoisten the soil when growing tomatoes, this can provoke the development of fungal diseases. It is enough to irrigate once a week after planting the seedlings. Regularity only increases with drought. The rate of liquid per bush is at least 5 liters. It is advisable not to flood the foliage during irrigation so that it does not turn yellow.
The Rio Grande tomato loves loose soil, so aeration should be done regularly (once every 10-15 days). Simultaneously with loosening, weeding is done, ridding the beds of weeds. The immersion depth of the instrument is at least 5-7 cm.
Experienced gardeners advise, after the first or second weeding, to huddle bushes to increase yields.
After transplanting shoots to an open bed, regular fertilizing is carried out:
Subsequent complementary foods consist of a solution of wood ash (for 10 liters of water 200 gr. Ash).
Immediately after transplanting the seedlings, the garden bed is mulched. This will help retain moisture in the soil without frequent watering and reduce weeding.
Many gardeners make ridiculous mistakes in agricultural technology that can negatively affect productivity. Among the main ones:
Strong immunity allows the variety to withstand many diseases and pests, but this does not mean that there is no need for prevention. If we are talking about cultivation in a greenhouse, then it is rational to replace the soil annually at the end of the season (a layer of at least 25-30 cm is removed). You also need to provide good ventilation when growing tomatoes.
Open beds before planting are watered with boiling water or a solution of potassium permanganate of low concentration... After planting the seedlings, regular treatments are carried out with biological products (for example, Fitosporin) or folk remedies in order to prevent fungal diseases or pests.
The following diseases pose the greatest threat to tomatoes:
Fungi and the virus more often infect weak plants, so you should not ignore the feeding schedule, as well as overdo it with the amount of fertilizer.
Among the dangerous pests are:
For prevention purposes, it is necessary to carefully remove vegetable debris from the beds in the fall. In it, larvae and adults of insects perfectly tolerate the winter cold. Before the first frosts, the ground must be dug up to reveal the nests of pests... This will get rid of most of the parasites. In the spring, in the aisles, it is worth planting plants that repel most insects: marigolds, marigolds, oregano, etc. If necessary, before the flowering period, treatment with insecticides should be carried out.
The Rio Grande variety is very easy to care for, has the ability to adapt to certain conditions, which is a good help in agricultural technology. If you make a little effort, then the plant will surely thank the zealous owner with a generous harvest.
Rio Grande tomatoes are the result of painstaking work by Dutch breeders. The plant can be cultivated not only in the open field, but also in the greenhouse. The bush is low-leafed, the length of its lashes is not more than 70 cm. It is not necessary to make grazing, installation of additional supports and tying these tomatoes. One shoot gives up to 10 ovaries.
Tomatoes with an average ripeness, from germination to the first harvest, takes from 110 to 120 days. Fruiting and harvesting lasts from June to September. This variety is often confused and called the Rio Sprint F1 tomato. However, these are two completely different tomatoes, differing both in appearance and in terms of ripening.
Grande's original fruits are small, weighing up to 150 grams, but at the same time fleshy. The aroma is strong, classic. There are few seed chambers. The shape of the tomatoes is slightly elongated, reminiscent of an oval. At the stage of technical ripeness, tomatoes are painted in a rich red color, for which summer residents often call them Red Grand.
The pulp is firm, with a characteristic sweet and sour pleasant taste. The description of the variety suggests that the fruits are endowed with a dense skin that prevents them from cracking even under adverse weather conditions. The dry matter content is high.
The Rio Grande tomato is characterized by a small, compact bush that does not require a garter or additional supports. The variety is cultivated both for personal consumption and on an industrial scale. The harvested tomatoes can be consumed both fresh and used for all types of processing and conservation.
The Rio Grande variety was bred by Dutch breeders and is suitable for both greenhouses and open ground. These tomatoes are grown by professional farmers and ordinary gardeners. The Rio Grande tomato shows good yield results everywhere. In climates with cold winters and the danger of frost in the spring, it is recommended to plant it under the covering material. The cultivation of the Rio Grande variety on loggias and glazed balconies is also widely practiced.
Tomatoes have a determinate bush - it is quite compact and does not take up much space in the greenhouse. The number of leaves on the plant is not very large - these tomatoes do not need to be pinned and tied up. This is convenient for small greenhouses where other vegetables can be placed. In an adult state, the bush of the variety reaches a height of about 65 cm. Ovaries are formed in an amount of 9-10 pieces, and the fruits ripen throughout the summer - from early July to September.
Advice! Since the Rio Grande is a varietal plant and not a hybrid, its seeds can be harvested for planting next year.
Tomatoes are suitable for harvesting at the stage of technical or physiological maturity. Tomatoes plucked in green ripen well during storage. When grown in large areas, harvesting can be done both manually and mechanically - the integrity of the fruits is not disturbed.
In the Rio Grande variety, the fruits have an average size and weight within 110 g. The shape is oval, reminiscent of a plum, the color is bright pink-red. Inside there is a small amount of seeds and the pulp is not very juicy, but has a pleasant aroma of tomatoes. To taste, the fruits of the variety are sweet, slightly sour. The skin is dense with a glossy sheen. In such a shell, tomatoes do not crack and are well stored.
The description of the fruits of the Rio Grande tomato corresponds to the presented photo:
Some disadvantages of the variety should also be mentioned. The pulp of "Rio Grande" is inferior in juiciness to large-fruited varieties. However, the taste is very pleasant.
Tomato "Rio Grande", with the description of which we have read, is a real decoration of any vegetable garden.
The Rio Grande tomato variety is quite resistant to major diseases: late blight, mosaics, gray and white rot. For the prevention of viral and fungal diseases, it is recommended to change the land in the greenhouse annually. For preventive purposes, the soil can be spilled with a hot aqueous solution of potassium permanganate or copper sulfate. When planning to plant seedlings in open ground, it is better to choose the beds on which legumes, cabbage, herbs (parsley, mustard or celery) grew.
You should not place tomatoes in areas that were occupied by other nightshades (peppers or eggplants). For the prevention of fungal diseases, frequent spraying of the bushes with phytosporin or another non-toxic bio-preparation is recommended. Mulching the soil with straw or humus, ventilating the greenhouse and moderate watering with drying of the topsoil will help to avoid many problems.
Insecticides can destroy pests, but they can only be used until abundant flowering and ovary formation. Naked slugs, which often appear in vegetable gardens, can be removed by regularly spraying with an aqueous solution of ammonia. Soapy water helps to fight aphids, with which the affected stems and leaves are gently washed.
Rio Grande is worth growing for those who are taking their first steps in gardening. The original Rio Grande tomatoes are unpretentious, as the description of the variety says, they put up with minor agrotechnical imperfections, easily tolerate heat, lack of moisture and slight acidity of the soil. Compact bushes will not take up much space in a greenhouse or garden beds and will certainly delight you with a bountiful harvest.
Rio grande can be grown in two classic ways: through seedlings or directly from seeds.There is essentially no difference: if you plant with seeds, then you will spend less time, but you will wait longer for the harvest, and with seedlings, the opposite is true - more time for preparation, but the harvest earlier.
The time for planting is chosen individually - the main thing is that by this time there are no severe frosts. Focus on the air temperature - it should not drop below +12 even at night.
The soil is preliminarily, a few days before planting, it is better to fertilize with organic substances: humus, manure, compost.
An important point - the soil needs to be treated with any antiseptic - this is a must, otherwise the plants are likely to grow sick.
Plant the Rio Grande in shallow holes - literally a few centimeters - so it will be easy for them to climb. Top - sprinkle with soil, it is not necessary to compact it.
Watering right away is also not worth it - moisten the earth with a spray bottle. The water should be slightly warmed, but not hot.
As mentioned above, these tomatoes are unpretentious and rather easy to care for.
