Productivity and quality of tomato hybrids with different garter of plants in spring greenhouses of the Rostov region

In the conditions of spring unheated greenhouses in the Rostov region on improved natural soils, the influence of the methods of tying tomato plants of various types of growth on the processes of crop formation and its quality indicators was assessed. The issues of the influence of methods of tying plants on the crop, its marketability, the share of early harvest and the average weight of the fruit are considered. It has been established that, on average, indeterminate hybrids, although they do not have a high total yield and the share of early production, however, have maximum marketability and average fruit weight. In determinant hybrids, the optimal combination of yield and quality was obtained from the Primadonna F₁ hybrid, for semi-determinant hybrids, for the Rozovyy nosik F₁ hybrid tied to twine, and for indeterminate hybrids, for the Makhitos F₁ hybrid, also tied to twine with a garter gun with a red ribbon for partial mechanization of the process.
