EFFECT OF BIOFERTILIZERS ON THE MORPHOLOGICAL CHARACTERISTICS OF THE BURDOCK

Using eleven treatments, the present study aimed at investigating the influence that organic and inorganic fertilizers exert upon the germination percentage, the length and weight (i.e. dry and fresh) of the shoot and root, and number of leaves which are considered the morphological characteristics associated prominently with the burdock that is technically entitled Arctium lappa. Significant differences were observed between such treatments as urea, vermicompost, vermicompost combined with Nitroxin, 15% manure in comparison with the control treatment in terms of the germination percentage. Another salient feature of urea and vermicompost treatments was that they led to a decrease in the rate of germination. Vermicompost treatments were proven to be significantly different in terms of number of the plant leaves. Shoot and root length was shown to be significantly influenced by the vermicompost treatments utilized both individually and in combination with Nitroxin. Compared with the control treatment, the experimental treatments were more significant as far as the weight of the fresh root and shoot was concerned. Another source of significant difference in terms of dry root weight was identified to be correlated with the 15% and 30% vermicompost individually used as well as the 15% vermicompost and manure employed in combination with Nitroxin. As for the dry shoot weight, no significant difference was witnessed between Nitroxin and 30% manure treatments.
