The effect of phosphorus and suspension of microorganism’s Azotobacter chroococcum and Pseudomonas fluorescens on root growth and phosphorus concentration in soybean plants exposed to a short drought stress was studied in a greenhouse experiment. The suspension of microorganisms was administrated in soil without or with P supply. Control plants were grown at normal moisture conditions 70% WHC (water holding capacity) and other part of plants at flowering stage was subjected to water deficit - 35% WHC. The results shown that drought reduced the morphological root parameters irrespective of level of P. Dry mass of roots, total root length, specific root length and fine roots increased in treatments with microorganisms application, in particular in treatment without P. The content of total P in soybean organs din not change significantly but it was observed an increase of Pi concentration due to P and microorganisms supply. |
