The cultivation with grafted seedlings is appropriate especially there where soil contamination reduces the yield of cultivated plants, or the plants are exposed to other types of stress (inadequate temperature, drought, salinity). Grafts in most cases have a higher yield because of a stronger and better-developed root system. In the case of grafting we never know whether the base and the graft will be consistent and whether it will be higher or better plants and yield. In this study, we compared growth and development and the yield of grafted and ungrafted peeper plants. In the experiment we designed in 2014, we included 4 hybrid varieties of pepper type ('Ramona F1', 'Bobita F1', 'Red knight F1' and 'AL65059 F1' and base 'Scarface'. We grafted plants 49 days after planting and successfully grafted plants, we were transplanted in a greenhouse on the laboratory field of the Biotechnical Faculty. The experiment was designed in three repetitions, 4 plants were planted in each plot, the plants were supplied with water and fertigated during the growth period, in July we started with collection and countion the fruits on the plant, and we measured the weight, the pericarp thickness and the content of total soluble solids in the average fruit. At the end of the experiment in November, we measured the final size of the plant and the mass of the plants with roots. The yield was bigger at grafted pepper plants and ranged between24 and 33 t/ha, according to the ungrafted plants (22-26 t/ha), as well as the average number of fruits per plant, only in the 'Red Knight F1' was the opposite results, lower yield had grafted plants (24 t/ha) compared to ungrafted plants (26 t/ha). The longest fruits have plants of 'Ramona F1' variety (for grafted plants of 8.9 cm and ungrafted plants 8.5 cm), and the shortest varieties of 'AL65059 F1' (grafted plants 7.1cm and ungrafted plants 6.7 cm). The widest fruits were recorded in the varieties 'Red knight F1' (7.2 cm for grafted and ungrafted plants), as well as the highest total soluble solids had content had fruits of this variety in ungrafted plants (7.6 ˚Brix), and the lowest plants of cultivar ‘Bobita F1' from grafted (4,2 ˚Brix) and ungrafted plants (4,4 ˚Brix ). We concluded the experiment on 27.10.2014.
