This study evaluated the effects of different soybean injury levels at early growth stages of the plants. The experiments were carried out in two different growing seasons, using a randomized complete block design, with 11 treatments in the first and 10 treatments in the second season, and four replications. The 'BRS 133' soybean cultivar was used, and the injury levels tested were: 1-Control; 2-Removal of 1 cotyledon; 3-Removal of both cotyledons; 4-Removal of both cotyledons + 1 unifoliate leaf; 5-Removal of both cotyledons + both unifoliate leaves; 6-Removal of 1 unifoliate leaf; 7-removal of both unifoliate leaves; 8-Cut below unifoliate leaves; 9-Removal of trifoliate leaf sprouts; 10-Total defoliation; 11-Total defoliation + removal of apical bud (only in the first trial). Injury was manually imposed, and insecticides were applied weekly to prevent injury by insects. The results showed that the soybean yield was reduced only when the injury was severe enough to cause plant stand reductions as a consequence of plant death. This occurred for treatments 5, 10 and 11. Under the other treatments, the soybean plants were able to recover. These findings show that the recommended economic threshold of 30% defoliation to initiate pest control is safe, and should be accepted by growers. Resposta da cultura da soja a diferentes intensidades de injúria nos estágios iniciais de desenvolvimento. Este estudo avaliou os efeitos de diferentes níveis de injúria nos estádios iniciais de desenvolvimento das plantas de soja. Os experimentos foram realizados em duas diferentes safras agrícolas em delineamento de blocos completos casualizados, com 11 tratamentos na primeira e 10 tratamentos na segunda safra, e quatro repetições. A cultivar utilizada foi a 'BRS 133' e os níveis de injúria foram: 1-Testemunha; 2-Remoção de 1 cotilédone; 3-Remoção de ambos os cotilédones; 4-Remoção de ambos os cotilédones + 1 folha unifoliolada; 5-Remoção de ambos cotilédones + ambas as folhas unifolioladas; 6-Remoção de 1 folha unifoliolada; 7-Remoção de ambas as folhas unifolioladas; 8-Corte abaixo das folhas unifoliadas; 9-Remoção do broto das folhas trifolioladas; 10-Desfolha total; 11-Desfolha total + remoção da gema apical (apenas no primeiro ensaio). A injúria foi realizada manualmente e inseticidas foram aplicados semanalmente para impedir injúria por insetos. Os resultados evidenciaram que a produção de soja foi reduzida somente quando a injúria foi severa o suficiente para provocar a redução do estande em consequência da morte de plantas. Isso ocorreu nos tratamentos 5, 10 e 11. Nos demais tratamentos, as plantas foram capazes de se recuperar, o que comprova que o nível de ação de 30% de desfolha que é recomendado para iniciar o controle é seguro e deve ser respeitado pelos sojicultores.

The last few years have seen the emergence of different initiatives designed to promote the biodiversification of agroecosystems as a counterpoint to the global expansion of homogenized industrial agriculture. In Brazil, two food procurement programs demonstrate the potential to promote discussions related to this agroecological transition: the National School Meal Program (Programa Nacional de Alimentação Escolar, PNAE) and the Food Procurement Program (Programa de Aquisição de Alimentos, PAA). The objectives of this paper are to analyze: (a) how these procurement programs currently integrate agrobiodiversity (crops and cropping systems) according to the local context; (b) the main challenges that key stakeholders perceive for the adoption of biodiverse systems; and (c) the extent to which the key stakeholders involved in these programs associate agrobiodiversity with the provision of ecosystem services. We carried out this research in 2017 in two contrasting municipalities in the eastern part of the Brazilian Amazon, Paragominas and Irituia. Our research shows that these programs have included up to 42 species in Irituia and 32 species in Paragominas. Perennial crop species are the most common type of culture in Irituia (up to 50%), while vegetables are the most common in Paragominas (up to 47%). Although in both municipalities stakeholders identify a large number of ecosystem services (up to 17), services mentioned in Irituia were more closely related to agrobiodiversity. Stakeholders indirectly associated with the programs have a broader view of ecosystem services. We conclude that these procurement programs can be useful tools to promote the biodiversification of local production systems, but their potential may depend on involving institutions not directly associated with their administration. Additionally, despite the observed differences in production context, providing more ecosystem services appears to be a compelling motivation for promoting changes in agroecosystems.
