“…Increased NUE in tomato, maize, and cucumber plants inoculated with PGPR have respectively been reported by Adesemoye et al [ 25 ], Zeffa et al [ 48 ], and Zhang et al [ 49 ], while such positive effects on NUE by PGPR was not seen in our study, as B.p. inoculation had little effect on DM ( Table 2 ) or total N uptake ( Table 3 ).…”

The effects of inoculating plant growth promoting rhizobacteria (PGPR) and soil water deficits on crop growth and physiology remain largely unknown. Here, the responses of leaf gas exchange, growth, and water use efficiency (WUE) of tomato plants to Bacillus pumilus (B.p.) inoculation under four irrigation strategies (I1-I4) were investigated in a greenhouse. Results showed that soil water deficits, especially at I4 (20%, v/v), significantly decreased leaf stomatal conductance (gs), transpiration rate (Tr), and photosynthetic rate (An), and the decrease of gs and Tr were more pronounced than An. Reduced irrigation regimes significantly lowered dry matter and plant water use both in the non-B.p. control and the B.p. plants, while reduced irrigation significantly increased plant WUE, and B.p. inoculation had little effect on this parameter. Synergistic effects of PGPR and deficit irrigation on leaf gas exchange, leaf abscisic acid content, and stomatal density were found in this study, and specifically, B.p. treated plants at I4 possessed the highest WUE at stomatal and leaf scales, suggesting that B.p. inoculation could optimize water use and partly alleviate the negative effects of soil water deficit. These findings provide useful information for effective irrigation management and the application of PGPR in agriculture in the future.

“…The Bacillus pumilus strain was provided by the Agricultural Culture Collection of China (ACCC 19290, Beijing, China). Fresh bacterial culture was prepared with the method described by Masood et al [ 49 ]. Then the pre-soaked plants were separately transplanted into 6 L pots; each pot contained one plant.…”

“…CC in leaves was measured with SPAD 502‐Plus. Fresh root morphology was measured by using a root scanner (EPSONV 700) and analysed with Win RHIZO software (Régent Instruments Inc.), to obtain the root length (RL), root diameter (RD), root surface area (RSA) and root volume (RV) (Zhang et al, 2019).…”

Aims:The effect of Bacillus strains combined with fish protein hydrolysates (FPHs) on cucumber root rot disease, seedlings growth and substrate nutrients was investigated. Methods and Results:We isolated three strains capable of mitigating cucumber root rot disease, XY-1 and XY-13 strains were identified as B. amyloliquefaciens, and XY-53 strain as B. subtilis. In the absence of bacteria, The 200×dilution (5 ml L −1 ) of FPHs was the optimum concentration for improving cucumber seedlings growth.In vivo antibiosis tests showed that combined bacteria alongside FPHs inhibited the pathogen growth by 85%~90%, higher than individual bacteria. The FPHs combined either with XY-1 and XY-53 strains or with XY-13 and XY-53 strains promoted seedlings growth under infection, whereas FPHs combined with a mixture of XY-1, XY-13 and XY-53 strains showed the highest total phosphorus and organic matter content in substrate. Moreover, FPHs combined with XY-53 strain increased urease activity, while combined either with XY-13 and XY-53 strains or with XY-1, XY-13 and XY-53 strains increased sucrase activity under infection. Conclusions: FPHs combined with B. amyloliquefaciens and B. subtilis had great potential to suppress growth of root rot and promote cucumber seedlings and increase substrate nutrient content.Significance and Impact of the Study: Co-inoculation of B. amyloliquefaciens and B. subtilis with addition of FPHs is a good strategy for maintaining healthy crops.

En la Comarca Lagunera, México, se encuentran invernaderos y casas de sombra dedicados a cultivar tomate (Solanum Lycopersicum L.), con alta productividad. Recientemente se inició la búsqueda de alternativas para mejorar la producción y satisfacer la demanda de alimentos sanos. El objetivo del trabajo fue caracterizar una bacteria aislada de la endorizosfera de plantas de tomate y evaluar su uso combinado con estiercol solarizado para promover el crecimiento y rendimiento de tomate bajo condiciones de invernadero. La bacteria fue identificada como Bacillus cereus mediante el análisis del gen 16S rRNA y mostró capacidad para solubilizar fosfatos (halo de solubilización 5.123 ±0.702 mm), producir sideróforos (halo 6.54 mm) y ácido indolacético (5.9 μg ml-1). En invernadero, semilla de tomate variedad saladette TOP 2299 se inoculó con B. cereus a una concentración de 1×108 CFU ml-1 y 46 días después de la siembra, las plántulas se trasplantaron en suelo enriquecido con estiércol solarizado a razón de 0, 40, 80 t ha-1 o con fertilización química (N-P-K 366-95-635). Los resultados muestran que la aplicación de B. cereus + 40 t ha-1 de estiércol solarizado ejerce una influencia positiva sobre las plantas de tomate ya que promovió mayor altura (16%), más volumen de raíz (42%) e incrementos en el rendimiento (20%).
