ABSTRACT
To study the effects of some new facilitators on the vegetative and morphological traits of Thymus kotschyanus, nine treatments were tested in the experimental rangeland field at the University of Mohaghegh Ardabili, Ardabil, Iran. Treatments included control, potassium silicate nanoparticles (PSN) with two levels of 500 and 1000 mg/lit, superabsorbent hydrogel (SH) with two levels of 10 and 30 g/kg, animal manure (AM) with two levels of 100, 200 g/kg, and effective microorganisms (EM) with two levels of 1 and 2%. Data were subjected to one-way analysis of variance (ANOVA). Results of mean comparisons of treatments for Thymus kotschyanus characteristics showed that the highest amount of studied traits were observed in the treated SH 30 g/kg. These traits include plant height (19.44 cm), basal area (4.66 cm), canopy cover (99.11%), number of secondary branches (9.44) and depth of rooting (16.49 cm), aerial parts volume (26.77 cm3), root volume (17.66 cm3), aerial parts fresh weight (14.40 g), aerial parts dry weight (7.18 g), root fresh weight (3.98 g), and root dry weight (2.07 g). In general, the impact of treatments on Thymus growth traits were ranked as follows SH 30 g/kg, PSN 1000 mg/lit, AM 200 g/kg, SH 10 g/kg, PSN 500 mg/lit, AM 100 g/kg, EM 2%, and EM 1%. In addition,the lowest plant traits were found in control. Overall, it is recommended extending the cultivation of this native medicinal plant by considering ecological conditions in each region. In addition, to promote the establishment and facilitate the growth of planted species, it is recommended using the facilitators utilized in the present work.
RESUMO
Para estudar os efeitos de alguns novos facilitadores sobre as características vegetativas e morfológicas de Thymus kotschyanus L., nove tratamentos foram testados no campo experimental de pastagens na Universidade de Mohaghegh Ardabili, Ardabil, Irã. Os tratamentos incluíram controle, nanopartículas de silicato de potássio (PSN) com dois níveis de 500 e 1000 mg/L, hidrogel superabsorvente (SH) com dois níveis de 10 e 30 g/kg, esterco animal (AM) com dois níveis de 100 e 200 g/kg e microorganismos efetivos (EM) com dois níveis de 1 e 2%. Os dados foram submetidos a uma análise de variância unidirecional (ANOVA). Os resultados das comparações médias dos tratamentos para as características de Thymus kotschyanus L. mostraram que a maior quantidade das características estudadas foi observada no tratamento com SH 30 g/kg. Essas características incluem altura de plantas (19,44 cm), área basal (4,66 cm), cobertura de dossel (99,11%), número de ramos secundários (9,44) e profundidade de enraizamento (16,49 cm), volume de partes aéreas (26,77 cm3), volume de raiz (17,66 cm3), peso fresco de partes aéreas (14,40 g), peso seco de partes aéreas (7,18 g), peso fresco de raiz (3,98 g) e peso seco de raiz (2,07 g). Em geral, o impacto dos tratamentos nas características de crescimento de Thymus foi classificado da seguinte forma SH 30 g/kg, PSN 1000 mg/L, AM 200 g/kg, SH 10 g/kg, PSN 500 mg/L, AM 100 g/kg, EM 2% e EM 1%. Além disso, as características mais baixas da planta foram encontradas no controle. Em geral, recomenda-se estender o cultivo desta plantamedicinal nativa considerando as condições ecológicas em cada região. Além disso, para promover o estabelecimento e facilitar o crescimento de espécies plantadas, recomenda-se utilizar os facilitadores utilizados no presente trabalho.
