The genus Brachiaria comprises more than 100 species and is the single most important genus of forage grass in the tropics. Brachiaria brizantha , widely used in Brazilian pastures for beef and dairy production, is native to tropical Africa. As a subsidy to the breeding program underway in Brazil, cytological studies were employed to determine the chromosome number and to evaluate microsporogenesis in 46 accessions of this species available at Embrapa Beef Cattle (Brazil). |

Sugarcane ratoons respond to nitrogen fertilizer application, but the N efficiency is low. Diazotrophs applied as a growth promoter bacterium can influence crop yield by several mechanisms, including a greater root growth and higher N absorption. The objective of the present work was to evaluate the stalk and sugar yields, and the economic index of sugarcane as a function of nitrogen fertilization and inoculation with diazotrophic plant growth-promoting bacteria (DPGPB). Two experiments were implemented in areas of two sugarcane mills in the state of São Paulo, Brazil: one in the Diamante Mill and one in the Santa Helena Mill. The experimental design was a randomized complete block with four N-fertilizer doses (0, 50, 100 and 150 kg ha?1), with or without DPGPB inoculation using five replicates. The application of the inoculant promoted a productivity increase in the Diamante Mill for all treatments with N, even in the absence of N-fertilization, while at the Santa Helena Mill that occurred with the 50 kg ha?1 dosage. The inoculation with DPGPB, together with the application of the 50 kg N ha?1 dose, achieved the highest economic return at both mills. The application of the inoculant associated with a low dose of N-fertilizer was profitable and proven feasible for field application. The results evidenced the viability of the technology for sugarcane production, with gains in productivity and a possible reduction in nitrogen fertilizatio |
