The aim of this study was to evaluate the effect of rhizobia isolated from adesmia native legumes (Adesmia latifolia) and serradella (Ornithopus micrantus) on the yield of four grasses of economic importance in the states of RS and SC: sudan grass (Shorghum sudanense L.
Those rhizobia were obtained from the collection of cultures of UFRGS Soil Microbiology Laboratory, the adesmia isolated EEL46210, donated by Epagri of Lages-SC and the SEMIA 929 and SEMIA 6437 strains, released by the Ministry of Agriculture, Livestock and Supply (MAPA) for the production of inoculants for serradella and adesmia, kindly provided by the collection of SEMIA strains of FEPAGRO.
The sequencing of the 16 S region of the ribosomal DNA of the strains currently released by MAPA (Ministry of Agriculture, Livestock and Supply) for the production of serradella inoculants (SEMIA905 and SEMIA929) and adesmia (SEMIA6437) and also of isolated rhizobia UFRGS Om57; UFRGS Om59; UFRGS Om148 and EEL46.
1 shows RER% of SEMIA 929 exceeding 150%, which indicates that in addition to fixing atmospheric N in serradella, SEMIA 929 stimulates the yield of millet through other mechanisms.
BRS 810), it was observed that the inoculation of rhizobia UFRGS Om57, serradella isolated, induced increase in shoot dry mass, being equivalent to that produced in non-inoculated plants and receiving addition of nitrogen equivalent to 100 kg of N ha-1 (NI 100 Control) and surpassing all other treatments (Table 1).
3) Implementation obsiewEw (sowing grass mix in the amount of 200 kg / ha Mix: Agrostis vulgaris, red fescue, perennial ryegrass, orchard grass, yellow lupine serradella
, white clover, vetch, field peas) - 7 912.
The species covered in the book include white clover; lucerne (alfalfa); red clover; subterranean clover; birdsfoot trefoil and greater Lotus species; alsike clover and sainfoin; and serradella, sulla, and tagasaste.
The inclusion of a chapter pertaining to serradella, sulla, and tagasate makes this book unique to the reviewer since these species are uncommon in agricultural systems in the USA.
