Produtividade do milho consorciado com Urochloa ruziziensis submetido à inoculação com Pseudomonas e Azospirillum brasilense

Abstract

Corn (Zea mays) is a cereal of great importance worldwide, placing Brazil in a prominent position in exports. The use of bacteria such as Pseudomonas and Azospirillum is presented as a tool to increase crop production. The intercropping of corn with forage plants such as Urochloa ruziziensis is a way to diversify the farm's production. Given the above, the objective of this work is to evaluate the development and productivity of corn and Urochloa ruziziensis intercropping submitted to inoculation with Pseudomonas and Azospirillum, and fertilization with organomineral. The experimental design was in randomized blocks, in a split-plot scheme, with four treatments and three replications. The area of the plots was 5 meters wide and 10 meters long. The treatments consisted of: (1) Control (Maize intercropped with U. ruziziensis); (2) Corn inoculated with Pseudomonas and Azospirillum intercropped with U. ruziziensis; (3) Corn intercropped with U. ruziziensis fertilized with organomineral; (4) Corn inoculated with Pseudomonas and Azospirillum intercropped with U. ruziziensis fertilized with organomineral. Maize inoculation with Pseudomonas and Azospirillum intercropped with Urochloa ruziziensis and organomineral fertilization did not increase the maize production variables, as the control did not differ.
