Las familias campesinas trabajan buscando en primera instancia su autoabasto y complementan su ingreso con otras actividades. En este trabajo se analizan las estrategias; multi actividad y autoabasto a través de los resultados obtenidos mediante entrevistas y la aplicación de una encuesta a 35 jefes de familia de la comunidad de Pueblo Nuevo, ubicada en el municipio de Acambay en el estado de México. Se practica una agricultura tradicional, se fusiona el sistema de cultivo de maíz blanco (criollo) y el sistema de crianza de ganado menor (borregos, vacas, porcinos, aves). En la fertilización, predomina el uso de fertilizantes nitrogenados. También se utiliza estiércol del ganado o aves como complemento, debido a que es fuente de nutrientes y materia... |

The objective of this study was to identify gliadin band patterns and the extent of genetic diversity in durum wheat genotypes from Northwestern Iran and the Republic of Azerbaijan. Gliadins from 46 landraces and four cultivars were evaluated through acid PAGE analyses. Sixty-six polymorphic bands and 81 patterns were identified. Twenty-four different motility bands and 22 patterns were found in the ω gliadin region with 14 polymorph bands and 20 patterns for α and γ gliadins, and 14 bands and 19 different patterns for β gliadins. The combination of these patterns generated 38 and 39 combinations for Gli-1 and Gli-2 loci, respectively. The genetic diversity index (H) was higher for α gliadins (0.924), followed by ω and γ gliadins (0.899 and 0.878,... |

The major objective of this study was to analyze and link the level of technical efficiency of Nigerian small-scale farmers to specific farmers' socio-economic and policy variables. Data were collected on 461 food crop farmers selected from five states of Southwestern Nigeria. The selection of respondent farmers was multi-stage and involved random sampling method, stratification as well as purposive sampling. The collected data were analyzed with the use of stochastic frontier production modeling technique. The results show that while farmers socio-economic and policy variables significantly influenced the level of technical efficiency, education has the highest marginal effect on technical efficiency while gender has the least marginal effect. The highest... |

Traditional growers of the Vale do Ribeira, São Paulo State, grow and make use of several D. alata landraces. This study assessed the genetic diversity of 16 landraces, using isozymatic and morphological markers and comparing them with 19 commercial varieties of D. alata. Their distribution in different levels of organization such as households and communities of the Vale do Ribeira was evaluated. Isozymatic analyses were performed with polyacrylamide (six systems) and starch gels (one system), while the morphological analyses were carried out with 24 traits. Due to the polyploid nature of this species, the isozymatic bands were scored as binary data. Morphological traits were also scored as binary data. Principal coordinates and cluster analyses were... |

The phenotypic diversity of sweet potato (Ipomoea batatas) landraces was assessed using morphological traits, verifying how this diversity is distributed among the households and settlements of the Vale do Ribeira, Brazil. A total of 74 accessions, involving 53 landraces, collected from 30 households distributed among 18 settlements that practice traditional agriculture in the municipalities of Iguape, Ilha Comprida, and Cananeia, as well as four commercial varieties acquired in markets of Iguape and Piracicaba, were evaluated under an ex situ experimental condition in Piracicaba, SP, Brazil. Nine phenological and floral descriptors, nine morphological vegetative aerial descriptors and five storage root traits were recorded. The 14 aerial vegetative and... |

In Brazil current studies and investments on yams are incipient. Similarly, the literature in recent decades lacks adequate information on this group of plants. The existing literature, on its turn, requires more than ever to be revised and organized. Yams have joined the so-called "neglected" group of crops for several reasons, but particularly because they are associated with poor and traditional communities. Many vegetables introduced in Brazil during the colonization period have adapted to different cropping systems, yams being an excellent example. This diversity resulted very widespread, yet poorly recognized in the country. In turn, the gardens using traditional farming systems continue to maintain and enhance yam local varieties. Studies from other... |
