The effect of biostimulants on yield and yield components of medicinal plant of Lallemantia iberica

In order to study the effect of biostimulants including mycorrhizae, green algae and humic acid on yield and yield components of Lallemantia iberica as medicinal plant, a randomized complete block design with three replications was done in the research greenhouse of Imam Khomeini International University. Biostimulants were studied at four levels including ۱- control (without biostimulants), ۲- application of mycorrhiza fungi, ۳- application of green algae and ۴- application of humic acid. In this experiment, plant height, number of branches per plant, number of pods per plant, number of seeds per plant, ۱۰۰۰-seed weight and seed yield per plant were measured. The analysis of variance showed that the effect of biostimulants on all traits except shoot dry weight was significant. The results of mean comparison based on the least significant difference test (LSD) showed that in all the studied traits, the lowest amount of traits was related to the control treatment, the highest amount of height (۳۳.۶۷ cm), the highest number of branches (۵), the highest number of pods per plant (۴۱), the highest number of seeds per plant (۵۲۰), the highest ۱۰۰۰-seed weight (۳.۹۷ g) and the highest seed yield per plant (۴.۱ g) was related to mycorrhiza fungi application treatment.
