PY - 2013/12/30 Y2 - 2024/03/29 TI - EFFICIENCY OF INOCULATION WITH INTRODUCE STRAINS OF STRAINS OF Bradyrhizobium japonicum AND Trichoderma harzianum ON SOYBEA GROWTH JF - Diyala Agricultural Sciences Journal JA - DASJ VL - 5 IS - 2 SE - Articles DO - UR - https://journal.djas.uodiyala.edu.iq/index.php/dasj/article/view/2965 SP - 257-263 AB - <p>The study was conducted to evaluate the effect of three introduced isolates of Bradyrhizobium japonicum (J.3 , J.5 and J.43 ) and local isolate of Trichoderma harzianum (T.26) . and their combination in some soybean growth parameters . The results revealed that all bioagents induced significant increment in all studied growth parameters which included root size , bacterial nodules number , stem length ,stem radius , fresh weight of shoot and root system and dry weight shoot and root system but isolate J.5 ( B. Japonicum ) superior than isolate T.26 and their bacterial isolates ( T.3 and T.43 ) in most growth parameters . The results also reveled that the combination inoculation induced significant increment in most growth parameters as compared to control treatment , the treatment (J.43 and T.26 ) was superior than other combination treatments in increasing root system size , number of bacterial galls ,stem length ,stem radius ,fresh weight of shoot and root system and dry weight shoot and root system which recorded (2.3ml , 8nod./plant , 36cm , 2.4mm , 3.8g , 0.92g , 1.2g and 2.0g ) as compared to ( 0.9ml , 0.0 nod./plant ,11.0 cm , 0.17mm, 0.5g , 0.1g , 0.7g and 0.2g) in control treatment respectively .</p> ER -
