The use of beneficial microorganisms in forage grasses is a potentially advantageous technique for a more sustainable pasture management by decreasing the need for chemical fertilization. Our aims were to determine the best method of microorganism inoculation on Brachiaria (Syn. Urochloa) brizantha cv. BRS Piata, compare the responses of inoculated plants of this forage grass with fertilized and unfertilized controls and examine its effect on some morphological, physiological and biochemical responses. On the first experiment, three inoculation methods were tested: in the seed, seed and soil, and soil, with Pseudomonas fluorescens (BRM-32111) and Burkholderia pyrrocinia (BRM-32113). In the second experiment, fertilized and unfertilized plants were either inoculated with BRM-32111, BRM-32113 and co-inoculated (BRM-32111 + BRM-32113). In a final experiment, B. brizantha was inoculated by soil drenching with BRM-32111, BRM-32113 and co-inoculated (BRM-32111 + BRM-32113), and compared to fertilized- and unfertilized-controls. The inoculation by soil drenching, at seedling stage, was more effective than inoculation only in the seed or both in the seed and by soil drenching. The fertilizer may have suppressed the beneficial bacterial effects on the growth of B. brizantha. P. fluorescens and B. pyrrocinia co-inoculated increased nitrate, protein, nitrogen concentration, Spad index (chlorophyll content), leaf area, number of tillers, net photosynthesis and total biomass production of B. brizantha plants. Our results point out to a potentially valuable source of practical information in the search of an eco-friendlier approach to increase pasture productivity.

Testes de sanidade de sementes realizados em papel de filtro com congelamento demonstraram que sementes de trigo, sabidamente contaminadas com Helminthosporium sativum, Pyricularia oryzae e Alternaria spp. tiveram a incidência desses fungos reduzidas quando colocadas em contato com colônias de Bacillus subtilis por períodos de 1, 3, 6, 12 e 24 h. A redução proporcionada pelos tratamentos com B. subtilis por 12 e 24 h foi, para P. oryzae e Alternaria spp., estatisticamente semelhante ao tratamento com a mistura Thiran + Iprodione (250g/100kg semente). Em testes de emergência realizados em caixas plásticas contendo solo desinfestado com energia solar, verificou-se que as sementes tratadas com B. subtilis por 1, 3, 6, 12 e 24 h apresentaram emergência superior aos tratamentos das sementes por igual período em meio sem a bactéria, e ao tratamento fungicida, embora não apresentassem diferenças estatisticamente significativas. |
