The Effect of Spraying Boron and Seaweed Extracts (kelpak) on Vegetative Growth Characteristics and Concentration of Some Medically Active Substances for Lemon Grass (Cymbopogon Citratus L.)

Abstract

This study includes the effect of spraying boron and seaweed extracts kelpak in the vegetative growth characteristics and concentration of some medically active substances for lemongrass plant. The experiment used a randomized complete block design with three replications. The Medians treatments have compared using Duncan’s test with multi limits at 5% possibility. The results arrived at can be summed up as follows. Discriminate treatment (B1K1) the highest rate of number of leaves (9.61 leave/plant) and the highest rate in plant height (134.14 cm), compared with comparison transaction ( B0K0 ) it gave the lowest rate for the number of leaves and less height of the plants. While the treatment giving overlap (B2K2) the highest moral value Percentage of dry matter for total vegetative (24.00) and the highest rate of percentage of dry matter for total root (33.00) and the highest rate of leaves area (168.08 cm2/leave) and the highest total chlorophyll concentration (35.18 SPAD) Compared with the least in comparison transaction ( B0K0 ) that gave less rate in percentage of dry matter for total vegetative and root and the less total chlorophyll concentration. Influenced treatment (B1K1) in the concentrations of the activeA substances to give it the highest concentrations of Myrcene (3.47 mg/gm) and Citral (28.01 mg/gm) and Limonene (42.72 mg/gm) and Geraniol (38.42 mg/gm) compared to the rest of the other transactions, while the lower concentrations of these in the treatment comparison ( B0K0).
