The application of bioinputs based on plant growth-promoting microorganisms represents a potential alternative for improving rooting efficiency. This study was conducted to evaluate, in two experiments, the rooting capacity of olive cultivars using microbial biostimulants and the effect of different biostimulants on seedling development during the nursery phase. The first experiment, focused on cutting rooting, was carried out in October using four olive cultivars: Arbequina, Maria da Fé, Ascolano 315, and Koroneiki. Cuttings were prepared and placed in masonry beds containing sand as substrate under controlled humidity and temperature conditions. The experimental design was completely randomized in a 6 × 4 factorial scheme (six biostimulants × four cultivars), with four replications and 25 cuttings per replication, totaling 100 cuttings per treatment. In addition to the control treatment (T1, IBA only), treatments consisted of biostimulants associated with IBA, including three Bacillus species: Bacillus amyloliquefaciens (T2), Bacillus licheniformis (T3), Bacillus subtilis (T4), Trichoderma harzianum (T5), and the commercial rooting product Bioraiz® (T6), all applied in liquid form to the substrate. Solutions were prepared according to the manufacturers’ recommendations, with a final volume of 3000 mL per treatment. Evaluations included rooting percentage, callus formation, and root system characteristics. The results indicated that the application of biostimulants enhanced rooting, with responses varying among cultivars. Increased rooting percentages were observed in the cultivars Maria da Fé, Ascolano 315, and Arbequina when treated with Trichoderma harzianum and Bacillus spp. Callus formation, particularly in Arbequina, was greater in the presence of Trichoderma harzianum, suggesting that this microorganism induces physiological processes related to rhizogenesis and improves root emission. The second experiment was conducted using olive seedlings approximately one year old, derived from the rooting phase and maintained under 70% shading. The experimental design was completely randomized in a 4 × 4 factorial scheme (cultivars × biostimulants), with three replications per treatment and two plants per replication. Plant height, stem diameter, and SPAD index were measured monthly over four months. Destructive analyses were performed to determine fresh and dry biomass of shoots and roots. The results demonstrated that seedling responses to biostimulants depended on genotype and the type of product applied, indicating interaction between cultivar and treatment. The use of seaweed extract proved promising for cultivars such as Ascolano 315, promoting greater initial growth and root system expansion. The use of microbial bioinputs can contribute to improved rooting of cuttings and enhanced growth of olive seedlings under nursery conditions.

The experimental design was randomized block in a splitstrip scheme with two additional treatments and four replicates. The primary strips consisted of three cover crop consortia: black oat + forage turnip (mix 1); white lupin + forage pea (mix 2); and oat + turnip + lupin + pea (mix 3). The secondary strips were: presence or absence of chicken litter (6 Mg ha-1). The sub-stripes were: presence or absence of rock powder (8 Mg ha-1). The additional treatments were: absolute control and control with chemical fertilizer. Penetration resistance (PR) down to 0.40 m, bulk density, porosity, and total soil carbon were evaluated in four layers (0.00.05; 0.05-0.10; 0.10-0.15, and 0.15-0.20 m) before and after harvesting summer crops (12 and 24 months after the start of the experiment). The dry mass productivity of cover crops was determined during the flowering period. Summer crops were manually harvested in the useful area of the plots, threshed, and weighed to assess productivity. The dry mass productivity of consortia was higher in the presence of rock powder and chicken litter; the use of rock powder, chicken litter, and cover crops in consortia provided higher soil TOC content; the use of chicken litter, as well as the association of cover crops in the presence of rock powder, promoted a reduction in PR; the consortia and the use of chicken litter and rock powder did not reduce soil density, but did not negatively interfere with macroporosity, microporosity and soil PT; the use of rock powder and chicken litter provided greater corn and soybean productivity.

The experimental design was randomized blocks in a split-strip scheme with two additional factors and four replicates. The primary strips were three cover crop consortium: black oat + forage turnip (mix 1); white lupine + forage pea (mix 2); oat + turnip + lupine + pea (mix 3). The secondary strips were the presence and absence of chicken litter (6 Mg ha-1). The sub-strips were the presence and absence of soil remineralizer (8 Mg ha-1). The additional factors were: absolute control and control with NPK fertilization. The chemical characteristics of the soil (pH, H+Al, P, K, Ca, Mg, V% and CEC) were evaluated at 6, 12, 18 and 24 months after the beginning of the experiment in the 0.00-0.10 and 0.10-0.20 m layers. Nutritional evaluation of corn and soybean grains (P, K, Ca and Mg) was also performed. The association of the remineralizer with chicken litter and with the consortia was efficient in improving and maintaining the chemical conditions of the soil at adequate levels, in addition to reducing the time required for the remineralizer to react; among the consortia used, oats + turnip provided the greatest effect in the association with the remineralizer and chicken litter; the use of the remineralizer, chicken litter and the oat + turnip consortium provided pH, H+Al, V%, CEC, P, K, Ca and Mg values similar to those verified in the control with NPK fertilization, demonstrating that soil fertility management with these alternative sources was as efficient as conventional chemical fertilization. The use of the remineralizer promoted higher P and Mg contents in corn grains and Ca and Mg in soybeans; the association of the remineralizer with chicken litter or with the oat + turnip consortium resulted in higher P contents in soybeans; The association of the remineralizer with chicken litter provided a higher K content in soybean grain. The principal component analysis indicated that among the soil chemical attributes evaluated, those that best explained the variability of the treatments used were pH, H+Al, Ca, Mg, V% and P. P was more related to the treatments that associated the remineralizer with chicken litter and with the consortia. pH, Ca, Mg and V% presented behavior contrary to that observed for H+Al, and the influence of these attributes did not follow a pattern as the evaluation period increased, also varying among the different treatments.
