| Abstract | It is proved by the results of research for 2018–2019 that the term of planting seedlings of basil variety Rutan significantly affects the phenological, biometric parameters of plants and the formation of yields of green mass and basil leaves separately. Regularities and differences in leaf area have been established. Plants grown at late sowing and planting lines have the smallest leaf area. It is proved that the area of leaves increases with late sowing row to 115,2 cm2/growth, which exceeds the control by 28,8 cm2. According to the correlation analysis between the number of leaves and the total leaf area, a strong direct dependence r = 0,90 was noted. Data from analysis of variance show that the area of leaves depended more on the factor of sowing rows – by 74 %. The weight of the aboveground part of the plants of basil variety Rutan at the time of planting in the third decade of April reached the level of 229 g, which is significantly higher than the control and the value of the mass at late sowing dates, where the figure was 160,4 g and 116,7 g. The total mass of the vegetative part of the plant includes a mass of young stems, inflorescences and leaves. The largest part is occupied by leaves – from 58,2 g in the late period, to 127,8 g in the early period, which is from 49,9 % to 55,8 %, respectively. Its yield in the third decade of April was 24,4 t/ha, which significantly exceeded the indicators obtained when planting seedlings in the second decade of May in the control of 7,1 t/ha. Lower yields of basil green mass were observed in plants planted in the first decade of May – 17,3 t/ha, which under the influence of high May temperatures was on a par with control. The yield of basil leaves of the Rutan variety for two years of research was at the level of 8,9–14,1 t/ha. High yields were obtained when seedlings were planted in the third decade of April – 14,1 t/ha, which is significantly higher than the control by 1,6 t/ha. Low yields were obtained when planting basil in the first decade of May – 8,9 t/ha, which is lower than the control by 3,6 t/ha. The best time for sowing when growing cassette seedlings of basil variety Rutan is the first decade of April and the use of cassette seedling growing method, which allows you to plant fully formed seedlings in open ground in the third decade of April and second decade of May and get the best biometrics and plant weight high yield of marketable green mass. | ||
