Diversifying the energy matrix, minimizing the use of oil sources, combating extreme weather events, are important strategies to mitigate environmental impacts. In this way, elephant grass (Pennisetum purpureum Schum. - BRS Capiaçu) is considered a prominent source of renewable energy containing high biomass productivity. Thus, the study was conducted to characterize the potential of the cultivar BRS Capiaçu, a recent genotype of elephant grass from Embrapa Gado de leite, in the production of energy biomass in the rainy season, grown in the city of Cachoeiras de Macacu. The treatments consist of four different experimental units, treatments 1, 2, 3 and 4, with four repetitions and cut performed at 180 days, in the month of November. The experiment was designed in a completely randomized design (DIC) with four samples and four replications, thus totaling 16 experimental units. The variables analyzed were dry matter (DM), mineral material or ash (MM), average plant height (AP), average number of leaves (EN), stem diameter (DC), number of tillers (NP), leaf production (PF), calorific value (PC), acid detergent insoluble fiber (FDA), nitrogen and lignin. Statistical procedures were performed with the R program and the means were compared using the Tukey test (p <0.05). In Productivity, the grass reached 21,713 kg / MS / ha in 180 days of harvest. The calorific value reached (17.91 MJ kg -1). The cutoff period in the rainy season accumulated a higher proportion of ash in the constitution of the plant, making heat transfer difficult.

Em mudas de Coffea arabica L. cv. Mundo Novo, cultivadas em solucao nutritiva analisaram-se os efeitos da nutricao de Ca e pH no crescimento, estado nutricional e colonizacao dos tecidos vasculares por Fusarium oxysporum f. sp. coffeae. Os tratamentos consistiram em cinco doses de Ca (0, 10, 100, 200 e 400 ml), combinadas com dois niveis de pH (4,5 e 6,5). Utilizou-se uma tecnica de inoculacao do patogeno na regiao do colo, realizada 105 dias apos a emissao das cotiledonares. Observou-se um aumento significativo no desenvolvimento das plantas quando os niveis de Ca na solucao foram de 0 a 100 mg ml, e uma reducao quando os niveis se situaram entre 200 e 400 mg Ca ml-1. Os tratamentos com Ca aumentaram as absorcoes de Ca e N e dimunuiram as de P,K,Mg,Mn e Fe, nao afetando, porem, as de Cu e Zn. A progressao do patogeno nos tecidos vasculares foi maior com pH 6,5 que 4,5. A percentagem de tecidos da raiz e caule colonizados aumentou com a diminuicao das doses de Ca na solucao (0 e 10 mg de Ca ml-1). A severidade da doenca geralmente diminuiu com o aumento de Ca de 200 e 400 mg ml-1. |
