“…Several authors suggest 10 8 CFU mL −1 as the preferred concentration at which a bacterial inoculum should be applied to the rooting medium of Eucalyptus cuttings [7,8,10]. Not all seven bacterial species in the current study were able to reach a growth concentration of ≈10 8 CFU mL −1 , and to ensure consistency, ≈10 7 CFU mL −1 was used for field applications, which was still considered suitable [49,50]. Although growth medium optimisation was not an objective of our study, it would be worthwhile to consider other nutrient media to increase inoculum concentration.…”

Clonal plantation involves the rooting of cuttings from superior genotypes selected for their hybrid vigor and desired qualities. However, the cuttings of some Eucalyptus species and their hybrid genotypes present difficulties in their rooting capacity. Applying PGPR to cutting growth medium as a root stimulating agent has not been extensively studied for Eucalyptus tree species. We aimed to assess the rooting capacity of cuttings taken from two poor-rooting Eucalyptus hybrid clones of E. grandis × E. nitens through the application of PGPR in nursery trials. Seven rhizospheric bacterial species that demonstrated the ability to produce indole-3-acetic acid and to solubilise phosphate were used to prepare two rhizospheric consortium inoculums in which Pseudomonas-Bacillus strains and non-Pseudomonas-Bacillus were grouped. Inoculums were tested for their rooting stimulating capacity on cuttings of the hybrids GN 018B and GN 010 and compared to the nursery standard indole-3-butyric acid. A total of 320 cuttings were treated. Both hybrid clones demonstrated significant (p < 0.0001) genotype differences for all three growth responses, i.e., total, root, and shoot length. Cuttings of both hybrids demonstrated high survival rates and rooting percentage. Although several rooting architectural configurations were prevalent, the Pseudomonas-Bacillus consortium promoted adventitious root development and fibrosity in GN 018B hybrids.

“…Agriculture in regions with a dry climate may benefit from biofertilizers (Schütz et al, 2018). González-Díaz et al (2019) observe that biofertilizers inoculated with nitrogen fixing bacteria of the genera Azotobacter and Azospirillum contribute to the crop yield of Eucalyptus grandis. In another study (Onyia et al, 2020), growth and yield of maize significantly improve when treated with biofertilizer.…”

“…Biofertilizers improve soil chemical and physical characteristics including with long-term action (Demir, 2020;Wang et al, 2021). Biofertilizers are effective for application in both open and protected crops (Wu et al, 2005;El-Ghandour et al, 2009;González-Díaz et al, 2019;Demir, 2020;Bergstrand, 2022).…”

“…Application of biofertilizers is an effective approach to sustainable agriculture. Biofertilizers are actively used for rooting cuttings, seed germination, and foliar nutrition (Wong et al, 2015;Alori & Babalola, 2018;González-Díaz et al, 2019). Nowadays, there are various biofertilizers in the global market labeled under different trademarks.…”

The concentration of supplied mineral nutrients is one of the most important and limiting factors for enhancing the efficiency of plant nutrition. Optimal concentration of nutrient solutions (NS) provide plants with the necessary amount of nutrients. From this point of view, research on several physicochemical parameters that characterize concentrations of NS and uptake of nutrients by the plants remains an actual problem. The changes of electrical conductivity (EC) and total dissolved solids (TDS) depending on the concentration of biofertilizer as well as the role of biofertilizer solutions on the rooting capacity of cuttings (lateral sprouts) of Callisia fragrans are presented here. The EC and TDS of the biofertilizer-water mixture changed gradually according to the biofertilizer concentration. The biofertilizer solution was a good medium for the rooting of C. fragrans cuttings. The results could help to provide the crops with the necessary amount of mineral nutrients and regulate the suitability of irrigation during the entire vegetation period.

“…Los datos fueron sometidos a un análisis de varianza (ANOVA) para determinar el efecto de los tratamientos sobre la respuesta de las variables, posteriormente se realizó la prueba de Tukey (p <0,05), para comparar las medias de los tratamientos, además los efectos cuantitativos (tratamientos con dosis de BF) se analizaron mediante regresión. El análisis de los datos se realizó utilizando el software estadístico SPSS 23 (González-Díaz et al, 2019).…”

Corn (Zea Mays) is the most cultivated cereal in the world and this is a staple food for human beings that is why in recent years they are looking for alternatives to improve their production. On the other hand, whey is a residual effluent from the dairy industry generally eliminated in sewage, however, due to its high organic load it can be used to produce different biofertilizers. The objective of this study was to evaluate the effect on the production of the corn crop when applying a biofertilizer obtained by anaerobic fermentation of whey and bovine manure. The study was conducted between October 2018 and February 2019, in the experimental area of the Calaspam association, located in Majes, Arequipa-Peru. A complete randomized block experimental design was used in a 2×4 factorial scheme composed by three biofertilizer treatments (6.9 and 12 LBF/water) and a control treatment with three replicates applied with an average flow rate of 1.5 Lha-1. Morphological, post-harvest and economic indicators were determined, as well as the chlorophyll content. Results indicate that biofertilizer treatments improved the indicators studied. The third treatment shows higher values in all the indicators compared to the other treatments, being the values of yield (79,29±7,33 103 kgha-1) and marginal return rate (85,73%) the most outstanding. It is concluded that the biofertilizer obtained from bovine manure and whey has a positive effect on corn production and its application is economically viable.
