Effect of Potabarvar and Sinorhizobium on Morphological Characteristics and Absorption of Some Nutrients in Fenugreek

Nowadays, the use of soil-born microorganisms as biological fertilizers is considered to be a natural and most desirable solution used to maintain sustainability of agricultural soil system. Potassium releasing, nitrogen fixing and phosphate solubilizing bacteria play role in providing K, N and P to plants. In order to evaluate the effects of biofertilizers Potabarvar2 and Sinorhizobium meliloti, on physiological properties and yield of Fenugreek, a complete randomized block experiment was conducted with five treatments and three replications. Treatments included biofertilizer Potabarvar2, Sinorhizobium meliloti, inoculation with a mixture of Sinorhizobium㺋婭ꫯ檽, positive control (based on soil analysis) and negative control (no fertilization and inoculation). Physiological and morphological characteristics and concentrations of N, P and K were measured after harvest. The results showed significant effect of Sinorhizobium on morphological characteristics except internode length. Symbiotic relationship of Sinorhizobium with Fenugreek increased the uptake of nitrogen and phosphorus, however the highest potassium uptake observed with a mixture of Sinorhizobium㺋婭ꫯ檽.
