### Bib/Limestone (BIB) Trials  
#### 3.2.1 Biomass Accumulation  
For the BIB cultivar, the plant biomass responded curvilinearly to nitrogen fertilization across both trials in accordance with typical luxury consumption trends (Table 3). Inoculation affected a significant increase in SDM (10.9%) and TDM in BIB1 (10.0%), and a significant increase in SDM (16.2%) and RDM (18.2%) in BIB2. TDM in BIB2, therefore, also significantly increased in response to inoculation (INOC; 906 \(\pm\) 294 mg, \(p\)\(\leq\) 0.0041).
