Tomagino Characteristics Tomagino is a cherry tomato on the vine with an average fruit weight of 19-20 grams. This variety stands out due to its consistent and high quality and flavour, and a crunchy “bite”. Tomagino produces cherry tomatoes with a very good, sweet taste from the first to the last vine. Brix levels of 10 are no exception. This variety is very resistance to split/cracked fruit, blossom end rot and shrinkage tears and therefore produces a very low percentage of class 2 tomatoes. Rootstock and cultivation Tomagino is generative in nature and requires a vigorous rootstock. During plant propagation Tomagino can be grown at higher 24hr temperatures and with less day-night difference than other varieties, due to its naturally generative nature. Lighting can be used, depending on the grower’s wishes and time of planting. Start of cultivation Tomagino is easily balanced due to its generative nature and open crop growth. This means that this variety is well-suited to a fairly level temperature regime. The aim is to cultivate a strong plant. We assume that the mats have been drip-irrigated with an EC of 3.8 – 4.2 mS/cm. With the exception of the period after being placed on the plant hole - during which the mat EC will increase sharply - the target EC value for the mat should ideally be between 4.5-5 mS/cm. The plant is placed on the plant hole before the first flower. Cultivation Tomagino is not a variety that tolerates extremes of temperature very well. The generative growth of this variety necessitates a fairly even and active growth strategy. Fruit setting occurs quite easily, even in poor light conditions, meaning that low pre-night temperatures are not necessary. Depending on the light conditions, the pre-night requirement will be in the region of 15 °C - 17 °C, with a temperature around 18 °C during the latter part of the night (+0.5 °C light). Maintain at least 16 °C if the weather is cold and clear. As the vine is quite compact in shape, it is important to achieve daytime temperature at 0.5 hours before sunrise in order to achieve sufficient stretching. The afternoon temperatures should be maintained at a “normal” level - avoid extremes - particularly during the first months of growth. A guideline is a maximum of 26 °C in combination with a venting temperature between 21 °C and 24 °C. Of course this all depends on light levels and external conditions. Tomagino produces an open crop type with relatively short leaves. It is important to maintain sufficient leaf span, particularly during the summer period. Truss pruning and treatment The vine, with an average of 16-18 flowers, is regular in structure and will produce few to no split vines. A vine pruning strategy for vines 1 through 6 could be: 10fr/10fr/11fr/12fr/ 12fr/12fr/13-14fr. Despite the fact that the truss stems are strong, kinked trusses can occur in the initial phase with low light conditions. It is not essential, but one could consider supporting a number of trusses. A movable and/or permanent screen is often used. Special attention should be paid to the use of these screens. If external conditions are mild and darker, then the screen should, if possible, be opened quickly to prevent growth of a weak and elongated plant. Active cultivation should always be the goal. In the case of a permanent screen, a tomato crop will easily get too long under these conditions. This should be taken into account when deciding on the climate settings, fertilisation (higher EC) and when to remove a permanent screen. Fertilisation Currently, no specific points of attention regarding fertilisation are known. However, it is important to monitor the ratio of Potassium/Calcium. Target figures in the mat are K 5 – 6 mmol/L ; Ca 10 – 11 mmol/L.
