Neste estudo analisou-se a viabilidade das tecnicas de hidratacao/desidratacao de sementes de tres cultivares de algodao herbaceo (Gossypium hirsutum L.), BR-1, Deltapine Smooth Leaf e Texas, de superar os efeitos deleterios da salinidade durante a germinacao. Antes da semeadura, um grupo de sementes das três cultivares de algodao nao recebeu nenhum tratamento previo (tratamento A1). Um segundo grupo foi hidratado por seis horas e lentamente desidratado por quatorze horas (Tratamento A2. Um terceiro grupo, alem de hidratacao por seis horas e desidratacao por quatorze horas, foi tambem submetido a um processo controlado de reidratacao por seis horas (tratamento A3). Sementes de algodao divididas nestes tres grupos foram semeadas em agua destilada ou solucao de NaCl de -0,8 MPa. Os tratamentos de hidra-tacao/desidratacao ou hidratacao/desidratacao/reidratacao minoraram os efeitos deleterios da salinidade na germinacao e no crescimento do sistema radicular das cultivares. Discute-se a im-portancia da hidratacao/desidratacao de sementes de algodao na superacao dos efeitos deleterios do NaCl pelo aumento da percentagem de germinacao das sementes e estimulo ao desen-volvimento das raizes. |

The poultry litter keeps the birds comfortable and absorbs the humidity generated in the environment, reducing the feet injuries. Then, its quality is essential. The objective for carrying out the present study was to evaluate the quality of the coffee husk poultry litter, treated with chemical additives, based on its humidity, N-ammonia, pH and bacteria total counting. The experiment was carried out in Minas Gerais state, Brazil, in a coffee producer region. It were used three facilities, in which it were placed circular boxes, each of them divided in seven parts, 2 m2 each one, where it were put the different types of poultry litter, being these the seven treatments: sawdust and coffee husks litter, being this last, new and untreated or treated with different additives and reused. Twenty-two chicks were distributed in each treatment (154 birds per facility, 11 birds m-2). Litter samples were collected at 7, 21 and 42 days of birds age. The experimental design was in randomized blocks, subdivided plots. The results were submitted to ANOVA and Tukey?s test. The hydrated lime increased the pH in the initial phase (7 days) and decreased the moisture of the reused litter, compared to the new one. The gypsum reduced the pH of the litter at the end of the second phase. The N-ammonia content of the reused litter, without treatment, was superior compared to the new one, untreated and treated with lime. There was no effect on the standard counting of bacteria and on the surface temperature of the litter. Then, the use of chemical additives in the poultry litter constitutes a good strategy to control its quality, as well as the environmental conditions to produce poultry meat.
