Growing tomatoes in film greenhouses is an important direction in modern vegetable growing. One of the promising methods for
increasing tomato productivity is grafting, which allows for the combination of positive characteristics from different varieties and types.
Non-standard grafting methods for tomato cultivation, such as cleft grafting and splice grafting, influenced the biometric indicators and
productivity of tomato hybrids with various growth types, providing options for cultivation in controlled environments. In cleft-grafted
tomato hybrids, where both the rootstock and scion had a determinate growth type, the highest degree of semi-determinacy expression
was observed. When grafting plants by the method of splice, all the hybrids we studied exhibited a higher degree of indeterminacy.
The impact of grafting on the duration of the growing season for tomato hybrids in controlled environments and the expression of late
maturity was confirmed; however, no effect of the grafting method on the flowering time of inflorescences was established. Hybrid
forms of tomatoes created through cleft grafting showed advantages in fruit yield over splice-grafted hybrids. The most productive
were the grafted hybrids Pink Delight F1 (13.8 kg m-1) and Ronda F1 (14.2 kg m-1). Increasing the productivity of the Pink Delight F1
tomato hybrid through grafting with a determinate rootstock, regardless of the method, provides an advantage when selecting hybrids
for cultivation in controlled environments.
