COMPARAÇÃO ENTRE O Bacillus megaterium E Pseudomonas fluorescens NO DESENVOLVIMENTO E REPRODUÇÃO DA CULTURA DO MILHO

Abstract

It is known that seeds are an important vehicle for the spread of many diseases, therefore it is important that the producer performs an adequate seed treatment. The gift work aims to evaluate the efficiency of applied Bacillus megaterium and Pseudomonas fluorescens in the planting furrow and as seed treatment in order to evaluate plant development of corn. The DBC design was used, divided into three treatments and seven replications, treatments; T1: control, T2: Cromobacterium + Azospirillum + Spinosa + B. megaterium, T3: Cromobacterium + Azospirillum + Spinosa + P. fluorescens, T4: Chromobacterium + Azospirillum + Spinosa + B. megaterium; T5: Chromobacterium + Azospirillum + Spinosa + P. fluorescens, where the characteristics of the height of the plant (cm), leaf width (cm), ear length (cm), the weight of the green mass (g), stem diameter (cm), ear weight (g) and number of grains on the ear. Therefore, through results, it is concluded that there was a positive response to the use of extracts as seed treatment, showing that bacteria have important functions for plants. Therefore, through the results obtained by these treatments, it is concluded that that, there was a positive response to the use of biological extracts as seed treatment, favoring plant growth, weight of fresh weight, quantity of grains and weight of spike. Showing that bacteria have important functions for plants, contributing to nitrogen fixation, P solubilization, making it usable for the metabolism of plants and also beneficial chemical compounds that are carried out due to their presence. From the results obtained, it is concluded that the use of Bacillus megaterium and Pseudomonas fluorescens generated very satisfactory results in the corn crop, mainly when applied directly to the seed.
