Foliar Spray Inoculation with Plant Growth Promoting Bacteria Associated with Nitrogen Doses in Megathyrsus maximus cv. BRS Zuri

This study evaluated the combined effect of foliar spray inoculation with plant growth-promoting bacteria (PGPB) and nitrogen doses on yield, development, nutritive value Megathyrsus maximus cv. BRS Zuri. The experimental design was randomized blocks four replications, repeated measures in time. Foliar two (Azospirillum brasilense Ab-V5 (CNPSo 2083) Ab-V6 2084) Pseudomonas fluorescens 2799)) 40 80 kg ha−1 N (urea) rates, addition to control (without fertilization), were applied. In rainy season, at level N, both A. P. increased, respectively, tiller number by 33% 25% (22 February), accumulated tissues 42% January), while previous year (21 February) beneficial effects observed percentage leaf blade true digestibility vitro. When inoculated CNPSo 2799, ha−1, root system Zuri grass increased 61% 30%, respectively.
