METALLOCENE EFFECT ON TOMATO GROWTH AND YIELD
The article presents research data aimed at studying the effect of Metallocen on the growth and production processes of tomato plants of different varieties (Salyut, Serna, Mirage and hybrid F<sub>1</sub> №2). In the control version, the plants were not treated, in the experimental ones they were sprayed three times with the tested preparation: the first after the seedlings took root, the second - at the beginning of flowering, the third - during the fruit growth phase. It was found that in the experimental versions, more powerful tomato plants were formed in terms of height, leafiness, bush diameter, and the number of fruits from the bush. Concentrations were determined for each variety: for F<sub>1</sub> hybrid №2 - 1500 ml/ha, for Mirage and Serna varieties-500 ml/ha, Salyut 1000 ml/ha. In these cases, the collection of high-quality fruit from the bush increased by 42,8; 36,8; 40,1 and 34,1%, respectively
