INFLUENCE OF PLANTING SCHEME ON BIOMETRIC INDICATORS AND YIELD OF SWEET PEPPER

Abstract

In the research sweet pepper Aphrodite of early ripening has been used for fresh consumption. To study the influence of sweet pepper planting schemes on the yield and biometric indicators, a line planting scheme of 70×15 cm has been chosen; 70×20 cm; 70×30 cm and tape 90+50×20 cm. For verification we take into consideration sweet pepper planted according to the scheme 70×20 cm.The values of biometric indicators significantly depended on the scheme of planting: the more optimal it was, the better the biometric indicators were. The height of sweet pepper plants in the fruiting phase differed depending on the chosen scheme. As a result of applying the tape scheme of planting 90+50×20 cm and scheme of planting 70×15 cm, the height of the plant was maximum and reached 39,1 cm or 36 cm and exceeded the control rate by 20,4 and 4,3 %, respectively. The larger diameter of the stem was obtained in variants using a row scheme of planting 70×15 cm and tape cm, in which the indicator was 9,3–9,5 mm.The amount of fruit on the plant depends on the planting scheme. In the control variant, the total number of fruit was 5,2 pieces, and in the variants of the experiment using the tape scheme 90+50×20 cm, the amount of fruits increased up to 6.8 pieces. The fruits met the varietal requirements, had a typical colour, and stayed in technical maturity.In our researches the fruit in shape and ripening period corresponded to the technical characteristics of the variety, but the average weight of the fruit was variable. The lowest fruit weight was obtained in the variant using the row scheme of planting seedlings 70×20 cm.However, the largest fruit weight was characterized by plants which were planted according to the tape scheme 90+50×20 cm, where the mass was 130,7 g and exceeded the control value by 5,2 %. The highest total yield was characterized by the variant where the plants were planted according to the tape planting scheme 90+50×20 cm. In this variant, the yield was 30 t/ha and exceeded the control by 17,6 %. As a result of applying the row scheme of planting 70×30 cm productivity on size conceded to an indicator of a control variant by 0,4 % and made only 24,6 t/ha.The Lewis stability coefficient lies in the range from 1,07 to 1,16, that indicates the typicality of cultivation technology for this area. As a result of applying the row scheme of planting of seedlings 70×20 cm or 70×15 cm the indicator increases to the size of 1,07 and 1,16 consequently.
