Tomato plants production process in the open field in the south of West Siberia

In the microplot filed experiment in the open field in the south of West Siberia (Novosibirsk region, Russia) tomato plants of indeterminate growth type (Delta 264 cultivar) yielded 2.4 kg/m2 more fruits as compared to the tomato plants of determinate growth type (Rannyaya lyubov cultivar) even when the growing was simultaneously terminated. Within the environmental gradient of experiment plots location there was no correlation between tomato plants production and soil chemical properties, most likely due to the variation in photosynthetically active radiation. The expected climate warming in the Eurasian part of Russia, especially due to the prolonged frost-free autumn period, will enhance the yielding advantage of tomato cultivars of the indeterminate growth type. Thus cultivation and further breeding of such tomato cultivars for the open field production is economically quite justified and important.
