A greenhouse experiment was conducted in the Soil Science Department of the Botucatu College of Agricultural Sciences (UNESP), Brazil, using a Dark Red Latosol in 25 L pots. The soil was limed to 50 and 70% of base saturation; and doses 0, 10, 20, 30 and 40 t ha-1 of chicken manure were applied, in December of 1999. The experimental design was completely randomized blocks with a factorial arrangement 5x2, 10 treatments and three replications. This work was carried to evaluate leaf number, height plants, fresh and dry weight by aerial part of sweet fennel, and macronutrients and micronutrients removal. The organic fertilization affected the accumulation of N, P, K, S, B and Mn; liming affected the nutrient uptake, except for the Ca, Mg, S and Fe; the interaction of factors affected K, Mg and Mn.

The buttonweed (Spermacoce latifolia) is becoming a plant among the most current infesting eucalypts plantation in State of São Paulo due to the continual use of same herbicides and control methods. Owing this, this work aimed to evaluate the effects of periods of company and control of S. Iatifolia on the initial growth of Eucalyptus grandis, planted in winter and summer. Only one seedling of Eucalyptus was planted in amianthus cement box and submitted for crescent periods of company and control of S. Iatifolia (0, 20, 60 and 80 days in competition or not). The densities of plants of S. Iatifolia were 4 and 16 plants per m 2 (under winner and summer conditions). The experimental period was 100 days after the planting (DAP). The experimental design for both experiments was the completely randomized blocks (CRB) with ten treatments and four replicates. The results of plant high, stem diameter, dries weights and leaf area showed that the before interference period (BIP), whole period of prevention for interference (WPPI) and critical period of prevention for interference (CPPI) were 40, 60, and 60 DAR, respectively, under winner conditions. Under summer conditions, the WPPI and CPPI were 20, 80 and 20 to 80 DAR.

Sericiculture is characterized by the possibility of income generation in areas smaller than 10.0 ha and by the rationalization of family labor. Even considering this favorable scenario for the development of this activity, there is still a gap in the management of its economic factors in most of the rural properties within this chain, contributing negatively to their expansion. This study aimed at assessing the production cost and economic viability for producing silkworm cocoons, by using a case study conducted in a property located in Quatá, São Paulo State, Brazil. The main results for a production of 1,904 kg-1 of silkworm cocoons, with labor costs reaching 51.5% of the Effective Operating Cost and 35.5% of the Total Operating Cost, were a profitability index higher than 50% and an Internal Rate of Return of 9.68%, for the second production year, providing a good profitability rate for this agricultural segment, when we consider that the improved profitability of the producer is proportional to the best production indicators, particularly due to the fast return that this activity provides.

A presente dissertação intitulada Desenvolvimento Local Sustentável como Liberdade: uma Experiência de Planejamento Estratégico do Grupo de Mulheres Erva Vida tem como objetivo principal analisar as perspectivas das participantes do grupo Erva Vida na discussão de estratégias que contribuam para o processo de desenvolvimento local sustentável. Alicerça seu arcabouço teórico, na apropriação do conceito de Instrumental Freedoms (IF’s) , discutidas por Amartya Sen (2000). São ao mesmo tempo o fim e o meio do processo de desenvolvimento. Estão entrelaçadas e se fortalecem à medida que são alcançadas. Essas liberdades instrumentais foram denominadas de political freedom; econômic facilities; social opportunities; transparency e guarantees e measures ensurig social protection and security. Para alcance dos resultados desta pesquisa, foram observados os aspectos internos e externos de uma organização social e análise das perspectivas de remoção de restrições a essas liberdades, a partir de uma experiência de Planejamento Estratégico conduzido junto ao grupo de mulheres Erva Vida, em Marapanim (PA). O grupo foi selecionado a partir de uma ação de economia solidária, desenvolvida pelo laboratório de Etnofarmácia, do Núcleo de Meio Ambiente da UFPA com uma associação de mulheres do bairro Sossego, no distrito de Marudá, em Marapanim (PA) envolvidas na produção de remédios artesanais. Considerando os resultados desta pesquisa, os produtos diretos constituem-se no documento de planejamento estratégico do grupo e num manual de orientação para facilitadores de planejamento local. Esses produtos podem contribuir indiretamente para o aperfeiçoamento das políticas públicas de desenvolvimento sustentável local na região amazônica, contribuindo, em linhas gerais, diretamente nas ferramentas para formulação de propostas para gestão de recursos naturais.

This work aimed to evaluate the carcass yields, commercial cuts and non-carcass components of Santa Inês lambs fed with 30, 40, 50 or 60% of oldman saltbush hay with concentrated. Were used 32 castrated lambs at 8 months old and initial body weight of 22 + 1.97kg, housed individually and slaughtered after 60 days of feedlot. The weights of hot and cold carcass decreased linearly with the inclusion of saltbush hay in the diet, however, there was no effect for true carcass yield and commercial cuts: shoulder (19.26%), neck (8.52%) ribs (26.57%) and leg (33.88%). There was a linear decrease for ribeye area and fat thickness when the level of hay in the diet increased. The weights and yields of skin, liver, heart, kidneys with perirenal fat, omental and mesenteric fats decreased linearly with the inclusion of hay in the diet, while the content (%) of gastrointestinal tract increased. The increased proportion of saltbush hay in the diet of lambs provided adequate true carcass yield and commercial cuts, however, reduces the ribeye area and fat thickness, important measurements in the qualitative evaluation of the lamb's carcass.
