“…In the absence of inoculation, PSS survival of 82.4% corroborates with the results found by Almeida Neto et al [67]. Although no other studies evaluate PSS survival in the field under the use of microorganisms, studies reported the PGPB action in improving rooting and nutritional aspects [37,[68][69][70][71].…”

Sugarcane plays a crucial role in global sugar and ethanol production. Conventionally, sugarcane propagation involves planting billets. However, Brazilian researchers have introduced the innovative pre-sprouted seedlings (PSS) method, widely used in the MEIOSI (Simultaneously Occurring Interrotational Method) system. Although PSS has several advantages over the conventional method, its sensitivity to water scarcity is a challenge. This study aimed to evaluate the survival and growth of PSS inoculated with Bacillus licheniformis and Bacillus subtilis (PGPB) under different water regimes. The experiment was conducted in the field in a randomized block in strips (split-block) using a 2 × 4 factorial scheme consisting of two inoculation conditions (with and without PGPB) and four water regimes (WR) (0%, 33%, 66%, and 100% of the ideal irrigation). PGPB increased PSS survival (4.17%) and water use efficiency (185.10% under the 0% WR). In addition, inoculation increased root (12.5%, 7.7%, and 16.2% for surface area, area projection, and root volume, respectively) and shoot growth. PGPB also increased nutrient uptake, such as N (60.8% and 18.3% under 0% and 66% WR), P (on average 11.7%), Mn (27.6% and 28.7% under 66% and 100% WR), Zn (111.4% under 0% WR), and Cu accumulation (27.17%), which provided a higher number of stalks per meter and, therefore, a higher multiplication rate in the MEIOSI system. Inoculation proved to be a promising alternative for PSS establishing under water restriction.

“…Regardless of the B. amyloliquefaciens dose used, Fusarium failed to show differentiation for the control of rot, persisting in all doses in the evaluated grains (Table 3), disagreeing with that observed by Ferreira et al (2021), which affirms that the use of Bacillus spp. is promising for the corn crop in Fusarium control.…”

Corn is one of the most important crops in Brazil and, due to its physiological characteristics, it has a high productive potential and high nutritional quality, for animal and human nutrition. Therefore, this work sought to evaluate Bacillus amyloliquefaciens subsp. plantarum FZB42 on agronomic characteristics and yield of corn crop. A randomized block design was used, with six doses of B. amyloliquefaciens subsp. Plantarum FZB42 (0.0; 2.5; 5.0; 7.5; 10.0, and 12.5 mL kg-1 seeds) and four repetitions, totaling 24 experimental units. The study was conducted in the experimental area of annual crops of the Instituto Federal de Educação, Ciência e Tecnologia do Sul de Minas Gerais (Federal Institute of Education, Science and Technology of the South of Minas Gerais — IFSULDEMINAS), Muzambinho Campus, in the 2017/18 agricultural year. The agronomic evaluations were: plant height, upper ear insertion height, culm diameter, leaf nitrogen content, forage fresh mass, incidence of Fusarium in the ear, number of rows per ear, number of grains per row, mass of 1000 grains, and yield. The nutritional evaluations performed were: crude protein, ash, ether extract, crude fiber, fiber in acid detergent, and fiber in neutral detergent. In summary, the inoculation of B. amyloliquefaciens subsp. Plantarum FZB42 in corn seeds, regardless of the dose applied, did not interfere with the agronomic characteristics and nutritional quality of corn silage.

Sugarcane plays a crucial role in global sugar and ethanol production. Conventionally, sugar-cane propagation involves planting billets. However, Brazilian researchers have introduced the innovative pre-sprouted seedlings (PSS) method, widely used in the MEIOSI (Simultaneously Occurring Interrotational Method) system. Although MPB has several advantages over the con-ventional method, its sensitivity to water scarcity is a challenge. The study aimed to evaluate the survival and growth of PSS inoculated with Bacillus licheniformis and Bacillus subtilis under differ-ent water regimes. The experiment was conducted in the field in a randomized block in strips (split-block) using a 2×4 factorial scheme consisting of two inoculation conditions (with and without bacteria) and four water regimes (0%, 33%, 66%, and 100% of the ideal irrigation). The bacteria increased the PSS's survival and water use efficiency in the field. In addition, inocula-tion increased root and shoot growth, as well as the nutrient uptake such as N, P, Mn, Zn, and Cu, which resulted in a higher number of stalks per meter and, therefore, a higher multiplica-tion rate in the MEIOSI system. Inoculation proved to be a promising alternative for establishing PSS under water restriction.
