| Abstract: The aim of this research was to analyze the permanence of ancestral practices used on growing potatoes, between the years 1950 and 2016. Two rural communities (Apatug and Puñachisag) were selected in the province of Tungurahua, Ecuador. Semi-structured interviews were conducted with 63 key informants selected with the snowball and group interview methods. Has characterized the agricultural calendar, the use of varieties, associativity and observation of lunar phases. The results suggest the temporal relationship of potato planting and harvest with the feasts ancestral religious. These cycles were observed until the decade of the sixties and seventies. However, with the agriculture modernization, these calendars are modified. On the other hand,... |

| Este estudo teve como objetivo avaliar os efeitos de diferentes sistemas agrícolas na comunidade de nematóides de uma área do Sistema Intergrado de Produção Agroecológica (SIPA) de Seropédica, Estado do Rio de Janeiro. Os tratamentos consistiram nos seguintes cultivos: 1- abacaxi; 2-feijão; 3- consórcio milho/feijão; 4- araruta; 5- pasto sujo e 6- capoeira. Os parâmetros avaliados foram: Abundância relativa, Grupos tróficos, índices de Shannon, Dominância, Equitatividade, IM, IM2-5, e a Análise faunística dos nematóides. A abundância relativa dos nematóides flutuou entre 0,02 e 0,59, o número de gêneros variou entre 4 e 14 e a riqueza acumulada foi de 21 gêneros. 79% dos nematóides encontrados foram fitófagos, 14,5% bacteriófagos, 4,7% onívoros-predadores... |

| ABSTRACT We aimed to compare the typology of dairy production systems (DPS) that meet Brazilian quality standards with that of non-compliant DPS. Semi-structured questionnaires were applied in 128 DPS located in Santa Izabel do Oeste, Paraná, Brazil (25°49'16" S and 53°29'04" W). In addition, milk quality reports of each DPS were analyzed. Dairy production systems were segregated into two groups: G1 – DPS that were in accordance with Brazilian regulations on milk quality, and G2 – DPS that did not comply with Brazilian regulations. Exploratory factor analysis was performed on structural, production, and technical variables. Two factors were defined: F1 – production scale and bargaining power, and F2 – autonomy and production control. Groups 1 and 2 were... |
