Abstract
The pot trial was performed to study the effect of L-tryptophane (as an auxin precursor) applied in the amount 0.3 and 3.0 mg per 1 kg of the soil on yield and the chemical composition of field bean. The effects of this compound on dehydrogenases activity in the cells Rhizobium leguminosarum isolated from root nodules, soil dehydrogenases activity and number of microorganisms from different systematic or physiological groups were also studied. The effects of L-tryptophane were compared to indole-3-acetic acid (IAA) after application to soil in the rate 0.2 mg per 1 kg of the soil of foliar spraying in the rate 20 mg Din 1 dm3 of distilled water. Studies were carried out in three experimental series: without microorganisms or with addition of Azotobacter sp. or Rhizobium leguminosarum biovar. viciae to the soil. It was found that L-tryptophane and IAA did not affect the yield of above ground part and roots of field bean and their effects on macronutrients concentration were not direct and dependent on the nutrient and experimental series. L-tryptophane and auxine increased the dehydrogenases activity in the cells of Rhizobium leguminosarum isolated from root nodules and the effect on the activity of soil dehydrogenases and urease was dependent on the rate of L-tryptophane. This chemical adversely affected the numbers of some microorganisms groups.
