Elephant grass ensilage might result in high dry matter (DM) loss and a reduction in feed quality. Knowledge of microbiota and the use of specific microbial inoculants can reduce DM losses and result in better fermentations and final products. The aim of the study was to characterise lactic acid bacteria (LAB) from elephant grass silages and subsequently select the promising strains to be used as microbial inoculants. Eighty-six LAB strains isolated from silages (7 from corn, 14 from sugarcane and 65 from elephant grass silages) were characterised and evaluated. Thirteen strains that showed the highest growth, pH reduction, production of interest metabolites and the ability to inhibit undesirable microorganisms and the strain L. hilgardii CCMA 0170 were evaluated in experimental silos. The aerobic stability, fermentative profile and microbial population of elephant grass silages of BRS Capiaçu cultivar were evaluated after 60 days of storage. No LAB was found in elephant grass before ensiling. The elephant grass silage fermentation was characterised by the succession of Lactobacillus sakei, L. plantarum group, Pediococcus pentosaceus and L. brevis. The silages inoculated with CCMA 0170 (L. hilgardii) CCMA 1394 and CCMA 1402 (L. plantarum), CCMA 1409 (L. brevis), CCMA 1363 and CCMA 1364 (L. farraginis) showed the smallest DM loss (mean of 38 g/kg of ensiled vs. 123 g/kg in control silage) and high aerobic stability (mean of 33.1 h vs. 21.2 h in control silage). Among the tested strains, the CCMA 1364 strain stands out as resulting in silages with low yeast populations, undetectable levels of butyric acid and high aerobic stability. Our results highlight the importance of the research and evaluation of new strains adapted to the fermentative process of each forage.

Cotton extracts around 69 kg of nitrogen (N) to produce a ton of cottonseed, thus depriving the soil with this nutrient in a few campaigns if it is not replenished by mineral or organic reposition. Soils poor in organic matter are used to cultivate cotton in Mozambique, and there is no fertilizer recommendation established for the area, resulting in low productivity. In this work is reported a study whose objective was to calibrate N fertilizer rates to recommend for this crop. The study was carried out in Muriaze, Province of Nampula, with treatments being the following rates of N: 50, 100, 150 and 200 kg/ha, in a complete randomized block design Every treatment was replicated four times, being each one 5 rows of 5 m each, spaced 0.9 m. All area received a basal fertilization with P2O5 equivalent to 120 kg/ha, as Triple Superphosphate, and K2O equivalent to 120 kg/ha, as Potassium Chloride. It was also limed with one ton/ha of calcium dolomite. The cultivar BRS 293 was used for the experiment, being planted in 21/12/2012, with a density of 10 seeds per lineal meter. It was evaluated parameters of growth and production. There was a severe hydric stress during growth and flowering of cotton, added to a strong attack of caterpillars into the flower buds. So, despite of the N fertilization to increase the number of apples/plant, there was not increase in plant growth and productivity. It is recommended that the experiment be replicated in time and in more than one place in the next campaign.
