||The results of studying the adaptability of sweet pepper varieties in the conditions of the Right-Bank Forest-Steppe of Ukraine are presented. The effect of varietal characteristics on the growth, development and yield of sweet pepper.
By biometric indication, it is possible to identify varieties with a high level of height, stem diameter at the rootstock, and the number of buds – Poltavs’kyy and Pioneer. These varieties had the largest number of leaves, of which there were 18,8–20,2 pieces on average per plant, and the leaf surface area index was 201,4–224,2 cm2/plant.
The first entry into the various phases of fruiting was observed in the Pioneer variety - the technical phase of maturity began for 18 days, and the biological phase - 20 days earlier than the control variety Valyusha. The yield of the crop during the period from mass stacks was obtained depending of the test variety, the earliest, after 105 days, to the Pioneer variety, and later, in 120–125 days, to the Valyusha and Nadia varieties. With respect to other varieties, the fruiting period was the longest for the Pioneer variety, which lasted 79 days. The term of this period of other varieties was at the level of 64–69 days.
Studies have shown that such varieties as Pioneer, Svitlyachok and Poltavs’kyy were characterized by a greater mass of early harvest, that its share in the mass of the total harvest was 32,6–38,5 %. The lowest level of the early harvest was characterized by the variety Nadia, the proportion of the harvest was 27,2 % in regard to the total mass of the crop.
From the obtained research results, the cultivation of the varieties Poltavs’kyy and Pioneer, which were selected by high productivity, was the most appropriate, which amounted to respectively 25,5 and 24,6 t/ha. The yield of the Nadia and Valyusha varieties was obtained at the level of 21,2 and 21,3 t/ha, which can be explained by the higher demands of these varieties on moisture and a negative reaction to the excessively high temperature of the soil and air
