Use of Microorganisms and Amino Acids in the Cultivation of Corn in the Second Harvest

The study was carried out during the 2021/2022 agricultural year by the company PCATheresearch siteislocated at18°68'south latitude, 38°31' west longitude, and is approximately 865 meters above sea level. The objective of this study was to evaluate the technical variables of the "phytobioassay" and the properties, using biologicals, amino acids and micronutrients in corn cultivation in southwest Goiás. The crop studied was corn, variety AG 8700 PRO3, and the treatment composition is T1: 0.0 ha-1 (absolute control); T2: 100 g ha-1 (SP) planting furrow + 100 g ha-1 (RV4B) reinforcement at stage V4 via application bar with the bacteria Azospirillum baldaniorum, Bacillus amyloliquefaciens; Bacillus proteolyticus and Pseudomonas aeruginosa; T3: Farm standard (TS): Seed treatment with Poncho and Acorde (Cropfield). The technological variables “Plant Biometrics” evaluated include Plant Population (PP) (DAP) carried out 30 days after germination, Plant Biometric Studies (aerial parts) at harvest, plant population, plant height, stem diameter, seed insertion height first ear, number of ears per plant, number of rows per ear, number of grains per row, number of grains per ear, ear diameter, cob diameter, grain length, ear length without chaff, thousand grain weight and productivity kilogram per hectare. The data were analyzed using the Sisvar procedure. The data obtained were subjected to analysis of variance, using the Tukey test to compare means, when significance of the analysis of variance was detected at p=0.05% probability for comparing means. Analyzing the results, we can conclude that there are no significant differences in all the technical variables studied, with the exception of productivity in kilograms per hectare, which obtained the best result, therefore we can state that the use of bacteria is highly viable in corn cultivation.
