Abstract

This article provides information on the study of hot pepper varieties «Margilan 330», «Uchkun», «Tillarang» in different planting schemes (70x20, 70x30, 70x40, 70x50 cm) in unheated greenhouse conditions. The quality and size of the fruit weight depended on the feeding area. As the plant's nutritional area increased, so did the commercial fruit weight and yield. According to the results of the experiment, the highest yield among varieties was 7,5 kg/m² when planting schemes 70x40 cm, 7 kg/m² when planting schemes Margilan 330 70x40 cm, 6,3 kg/m² when planting schemes 70x40 cm. The study of the biochemical composition of fruits also reported an increase in the amount of dry matter, ascorbic acid (vitamin C), bitterness, mono and disaccharide, nitrate in high-yielding varieties. According to the results of the study, the nitrates in the fruit of hot pepper are in the minimum and maximum range (120-180 mg/kg), indicating that they do not affect the human body.
