Growth dynamics of tomato fruits as a main indicator of a phytomonitor

Abstract

The study of the growth dynamics of tomato fruits in greenhouses using a phytomonitor, in particular, a fruit growth sensor, shows indicators that are invisible to the human eye. Their dynamics during the day and throughout the entire period of fetal development, starting from a size of 2.7 cm to removable maturity and redness in a graphical form, allows you to quickly identify a slowdown in growth, quickly find a limiting factor and reveal the influence on the growth rate of factors such as brush rationing and cleaning other fruits in it. It must be said that the use of a phytomonitor in practice requires high qualifications of an agronomist. And if the farm does not have a sufficiently high level of agricultural technology or the staff does not know how to use the indicators of sensors, there is no point in looking for a limiting factor. For this reason, in the greenhouses of Corporation “Kombinat Teplichny” (Kiev region, the village of Kalinovka), after several years of use, they abandoned the phytomonitor, which did not recoup the funds invested in it. For Ukraine, it remains exotic, therefore, the article contains an extended description of the phytomonitor.
