Growth and development of Tagetes patula grown on vermisubstrate in closed ground

Abstract

To study the growth and development of Tagetes patula on substrates of various composition, looking for vermicompost in a closed ground, we studied the biometric indicators and characteristics of the pigment complex (nitrogen balance Nbi, flavonols – Flv and chlorophyll – Ch). In the obtained results, the differences were statistically significant when comparing the median morphometric indices of plants on substrates BK-3a; and BK-2 for both periods of vermicomposting. It was established for substrates f vermicomposting for 90 days that there was a statistically significant difference between (P< 0.05) the compared samples of the Nbi index in the BK-2a; and BK-3a;, in chlorophyll when comparing the control with BK-3a;. It was noted that in vermisubstrates for a period 150 days, statistically significant differences were found in Flv in the BK-2б and BK-3б variants, with the Wilcoxon criterion P = 0.01; control with BK-2б, at P = 0.02. This indicates a significant effect of these substrates on the development of Tagetes patula. In this experiment we failed to prove a similar effect for the remaining soil types (P > 0.05).
