Abstract

The article describes the most effective technologies for growing indeterminate tomato hybrids in greenhouses, created in local conditions by the private enterprise "GREEN VALLEY SEEDS". The results of phenological observation of tomato hybrids planted in greenhouses during the summer-autumn season in the experiments during 2022-2024 are presented in Table 1.

It was observed that when the seedling density of tomato hybrids planted in the greenhouse was 2.8-3.2 seedlings per 1 m2, the yield increased significantly (0.8-1.1 kg-m2) compared to the standard (2.5 seedlings per 1 m2).                                    In addition, the experiment studied the effect of shaping tomato seedlings in different ways on yield. According to the results of the experiments, when 25% of the seedlings were left with additional shoots, the yield increased significantly compared to the one grown as a single-stem variety without side shoots. It was found that the yield of the Tong F₁ hybrid was 5.3 kg/m2 without side shoots, 6.2 kg/m2 when 20% of the seedlings were left with side shoots, and 6.5 kg/m2 when 25% of the seedlings were left with side shoots, which is 1 kg/m2 more than the standard. As a result of the experiments, the most effective variant of the standardization method of yield crowns was found to be the standardization method of 5 crowns. When using this method, it was found that the yield of the Tong F₁ hybrid increased by 1.6 kg/m2 compared to the standard variant.
