Abstract: (465 Views)
In order to evaluate the effect of phosphate and silicate solubilizing bacteria on grain yield and biochemical compounds of Milk thistle and Fenugreek in intercropping conditions, a three replicated RCBD factorial experiment was conducted in 2019 in Kohgiluyeh and Boyar Ahmad provinces, Yasouj, Iran. Five different levels of fertilizers includes phosphate solubilizing bacteria, silicate solubilizing bacteria, phosphate solubilizing bacteria + silicate solubilizing bacteria, and phosphate and silicate chemical fertilizers versus control (no fertilizer) as the first factor, were evaluated in different intercropping patterns (monocropping of Milk thistle, monocropping of Fenugreek, intercropping of Milk thistle and Fenugreek with arrangements (1:1) and (2:2)) as second factor. The results showed that the simultaneous application of phosphate and silicate solubilizing bacteria increased the chlorophyll a of Fenugreek (45%) and Milk thistle (21%), the total chlorophyll of Fenugreek (20%) and Milk thistle (22%), and the carotenoid of Fenugreek (60%) and intercropping pattern (2:2) caused a significant increase in chlorophyll b of Fenugreek (16%) at the probability level of one percent. The highest phenol rate of Milk thistle was obtained from the intercropping pattern (2:2) and the simultaneous application of bacteria, and the highest antioxidant property of Fenugreek was obtained from the intercropping pattern (1:1) and the simultaneous application of bacteria. The application of solubilizing bacteria increased the phenol of Milk thistle and the antioxidant property of Fenugreek extract in all cropping patterns. The highest percentage of seed oil in both plants was obtained from the intercropping pattern (2:2), and the simultaneous application of bacteria and the highest yield of Milk thistle seeds were obtained from the intercropping pattern (2:2) and chemical fertilizer. In general, it could be concluded that the application of microbial species will probably improve the yield and percentage of seed oil. In addition, better conditions for both plants in the intercropping system and more available nutrients resulting from microbial activity will increase the production of secondary metabolites and improve antioxidant property, phenol and flavonoid contents of the oil.
