Abstract
To study the effects of drought stress and bio fertilizers on quantitative and qualitative characteristics of medicinal plant Silybummarianum, a study in the field of education – research, agriculture, University of Zabol,2012, as split plot in completely randomized block design with three replications was performed. Experimental treatments included different levels of irrigation regimes consisting of ٪80 of the field capacity(control), ٪60 of the field capacity (Mild stress), ٪40 of the field capacity (Severe stress), as a major factor and 5 levels of bio fertilizers included lack of fertilizer(Control), Nitroxin fertilizer rate of 300 ml per kilogram of seed, Nitroxin fertilizer rate of 600 ml per kilogram of seed, super Nitroplus rate of 300 ml per kilogram of seed, super Nitroplus rate of 600 ml per kilogram of seed as a minor factor. The results showed that the drought stress has impact on the quantitative characteristics of the plant, such as the number of inflorescences per plant, number of tributaries, number of inflorescences, number of seeds in capitol, thousand grain weight, and grain yield. The amount and yield of essential oil grain under mild drought stress (60٪ of field capacity) was increased. The effect of bio fertilizers on all traits was significant. The interaction of drought stress treatments and bio fertilizers on thousand grain weight, grain yield, percent of essential oil and yield, ash percentage, organic matter percentage and praline were significant. According to the results of this thesis, it appears that the use of 60٪ of the field capacity and Nitroplus bio fertilizer rate of 600 ml per kilogram of seed is the best treatment in the production of the active substance of Silybummarianum in terms of organic farming.
