Innovación tecnológica en la producción de jitomate (Lycopersicon esculentum) en invernadero por productores de milpa tradicional en Santo Domingo Teojomulco y San Jacinto Tlacotepec, Oaxaca.
Provedor de dados: 32
Autores: Ortíz Jiménez, Bersaín.
La tesis comprende el estudio de unidades familiares que producen jitomate en invernadero y realizan actividades productivas de autoconsumo como lo es la milpa. Se realiza el análisis del grado de adopción de innovación tecnológica en la producción de jitomate en invernadero y los flujos de conocimiento sobre tecnología entre los productores; también se analiza la productividad y sustentabilidad de los sistemas agrícolas de la unidad familiar. El índice de adopción (InAI), se obtiene a través del análisis de variables latente de los componentes tecnológicos, comparando el antes y después del proceso del método de las escuelas de campo para la difusión de tecnología; con el método de redes sociales se observa el flujo de conocimiento y relaciones de cada...

Methodological and empirical progress and challenges in integrated assessment of agricultural systems and policies
Provedor de dados: 31
Autores: van Ittersum,   Martin K.; Heckelei,   Thomas; Oude Lansink,   Alfons G.J.M.; Wolf,   Joost; Kanellopoulos,   Argyris; Britz,   Wolfgang.
In this contribution we first present a methodology for integrated assessment of agricultural systems (SEAMLESS Integrated Framework), illustrate its application in an integrated assessment of high commodity prices and then discuss its flexibility and limitations. From there we take a broader view and reflect on key scientific and empirical questions with respect to the development of research tools for the integrated assessment of agricultural systems.

Provedor de dados: 96
Autores: Defante,Leslié; Damasceno,Julio Cesar; Bánkuti,Ferenc Istvan; Ramos,Carlos Eduardo Crispim de Oliveira.
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...

Application of a model of management by macroprocesses to a beef cattle enterprise: a case study
Provedor de dados: 96
Autores: Rosado Júnior,Adriano Garcia; Lobato,José Fernando Piva.
This is a case study that aimed at proposing a management method based on macroprocesses to determine and achieve strategic goals for a beef cattle enterprise in order to maintain or to increase the company's competitiveness. The method suggests using a series of tools mentioned in the literature that were organized providing logical reasons for the managers to build the management system. When mapping the processes of the studied enterprise, four macroprocesses were identified, which were sustained by 21 support processes, in addition to three management processes. The strategic aims were determined by the internal and external environmental analysis, resulting in five priority items, and the processes considered critical to achieve them were described by...

Ancestral practices in potato ( Solanum tuberosum L.) crop of two rural communities in the Tungurahua, province of Ecuador
Provedor de dados: 109
Autores: Pomboza-Tamaquiza*,Pedro Pablo; Paucar,Dario; Cruz-Tobar,Saúl Eduardo; Núñez-Torres,Oscar Patricio; Velástegui-Espín,Giovanny Patricio.
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...
