The need of sustainable methods for agronomical practices requires practices and inoculants that have a positive impact on both crops and the natural environment. The maize (Zea mays L.) is one of the most important and multifaceted crops in agri-food system at global level. The aim of the study was to assess two Bacillus sp. preparations as potential maize biofertilizers under field conditions.

The need of sustainable methods for agronomical practices requires practices and inoculants that have a positive impact on both crops and the natural environment. The maize (Zea mays L.) is one of the most important and multifaceted crops in agri-food system at global level. The aim of the study was to assess two Bacillus sp. preparations as potential maize biofertilizers under field conditions. The analysis was carried out comparing the formulations based on Bacillus safensis S9 and B. velezensis ZAV-W70 bacteria, under field conditions, at two different scales. First, a trial was carried out at plant scale on two commercial hybrids of maize KM3916 VIP3 and P2089 VYHR (KWS and Pioneer seedbeds respectively). Overall, a yield increase was observed in the presence of both strains in comparison to control, with some particularities for each maize hybrid. The KWS showed an important loss of controls plants spikes, while both Bacillus strains increase the number of grains and yield between two and three times for S9 and ZAV-W70 respectively. On the other hand, the Pioneer hybrid showed a significant increase of nearly 50 % in number of grains and yield for ZAV-W70 strain. On the other hand, a second trial was made at parcel scale using standard agronomic practices, and the Pioneer hybrid. The S9 strain showed a diminution of the 80 % of lodging, while the Zav70 strains produced a significant increase of 5 % in number of kernels by square meter, while the yield was increased a 1.2 % as consequence. In conclusion, our results suggest that the B. safensis S9 and B. velezensis ZAV-W70 strains can be considered for further studies as maize biofertilizer.
