Abstract: the purpose of this study was to assess the indicators of social capital and the innovation dynamics in two groups of corn producers in the same social network, one with productive units of less than 2.2 ha (small farmers) and another with properties of 6.44 to 150 ha (midsize farmers) in a representative sample of the rural development district 088, zamora, michoacán de ocampo, mexico. we used the theoretical concepts of social capital in order to identify the elements involved in the enhancement of technological and institutional capabilities in the framework of the innovation process and its transmission to the rural sector. the methodology used was based on innovation and social relationships networks. midsize producers had an average yield of 5.75 t/ha-1, almost three times higher than what smallholders achieved, largely due to their rate of adoption of innovations (inai), which was 48.22%, in contrast to 12.55% in the other group, and to their excellent trust relations (social capital). furthermore, the midsize farmers' network is more comprehensive because it has higher density, size and number of links, and a smaller standard deviation. in addition, their centralization index is lower than in the small farmers' network, a fact related with unequal access to information and knowledge.

Abstract: the loss of profitability of bean farming in mexico, together with an increase in imports and free market conditions, makes beans less competitiveness in comparison to the united states, mexico's main trade partner.the objective of this research was to analyze mexico's bean production competitiveness under free market conditions; at the macro level, competitiveness was negative, due to an overvalued currency that favors import dumping, and also to the fact that bean production is no longer protected by the north american free trade agreement (nafta), because protective tariff were canceled. at the meso level, the establishment of farmers' organizations has favored producers, who have been able to achieve market scale economies, although consolidation is needed. a field study at the micro level, in the state of chihuahua, showed that production costs are high and yield costs are low, which generates lower competitiveness compared to the united states.

Abstract: the objectives of this work were to characterize strawberry growers in zamora, michoacán, mexico, and to identify factors limiting production with the methodology of innovation networks. the state of michoacán is the largest strawberry producer in mexico, but production is extensive and disorganized. the productive system network of strawberry has a large number of nodes, but dispersion is high. this fact is reflected in the scarce number of links (265), a low density and an elevated standard deviation (12.47 %). the centralization index is 18.36 %, in part because decision-making and access to system information in the web are concentrated in only two actors; one of them is a final buyer and the other is a local lender. the strawberry agribusinessmen from michoacán interviewed had a mean yield of 24.44 t·ha-1. their per hectare income was $ 9,208 uscy, but with a cost of production of $11,867 uscy and an index of innovation adoption of 55.56 %. the adoption of organizational innovations is limited. all these factors originate low macro competitiveness. it is necessary to enhance innovation to increase the competitiveness.

Región y sociedad , 2008,
Abstract: La pérdida de rentabilidad del cultivo de frijol en México, aunada al incremento de los volúmenes de importación y la desregulación del mercado, ocasiona que el grano sea cada vez menos competitivo en relación con el cultivado en Estados Unidos, su principal socio comercial. El objetivo de esta investigación fue analizar la competitividad de la producción de frijol en México en el marco de la liberalización comercial; se encontró que a nivel macro, ésta es revelada negativa, debido al tipo de cambio sobrevaluado que favorece el dumping en las importaciones, además de que ha quedado desprotegida por e l Tratado de Libre Comercio de América del Norte (TLCAN), al omitirse el pago de aranceles. A nivel meso, la formación de organizaciones ha favorecido a los productores, que han logrado crear economías de escala, aunque les falta consolidarlas. En el estudio a nivel micro, en Chihuahua, se observó que los costos de producción unitarios son elevados y los rendimientos bajos, lo que resulta en una rentabilidad menor en comparación con la de Estados Unidos.

Revista mexicana de ciencias agrícolas , 2012,
Abstract: Se realizó un estudio para analizar la rentabilidad, el porcentaje de adopción de innovaciones y la atribución causal de la reticencia a adoptar innovaciones y al trabajo colectivo de horticultores de brócoli y apio, que son cultivos representativos de las hortalizas del Distrito Federal. Al hacer un comparativo de la rentabilidad de la producción entre México y Estados Unidos de América, se puede observar que los horticultores mexicanos obtienen una ganancia mucho menor que los de EE.UU, a pesar que sus costos de producción son menores, debido al bajo rendimiento obtenido en el Distrito Federal. El porcentaje de adopción de innovaciones (INAI) de los agricultores(as) del Distrito Federal fue 15%, que se considera muy bajo. Esta es la principal razón del bajo rendimiento y la reducida rentabilidad. Tanto productores como funcionarios manifestaron que la atribución causal a no adoptar innovaciones y no realizar trabajo colectivo, es debido en primer lugar a la desconfianza, en segundo lugar al desconocimiento y en tercer lugar a la falta de tiempo. In order to analyze the profitability, the adoption rate of innovations and causal attribution of the reluctance to adopt innovations and collective work of growers of broccoli and celery, which are representative crops of vegetables in México City a study, was performed. By making a comparison of the profitability of the production between México and the United States of América it can be seen that, Mexican growers make a much lower profit than the U.S., even though, the production costs are lower, due to a low yield in the Federal District. The rate of adoption of innovations (INAI) of the farmers from the Federal District was 15%, which is considered quite low. This is the main reason for low yield and reduced profitability. Both, the producers and officials said that the mainreason for not adopt innovations and not working as a group, is primarily due to mistrust, and second is the ignorance and the third is the lack of time.

Abstract: El sector agropecuario en México es cada vez menos competitivo, dado que existe una creciente importación de alimentos, lo que implica la existencia de menor capacidad de producirlos y distribuirlos en el mercado. El objetivo de la presente investigación fue analizar indicadores macroeconómicos, para cuantificar la competitividad del sector agropecuario en México y su tendencia, dentro de un marco de apertura comercial. La competitividad aditiva revelada resultó menor de cero, con una tendencia decreciente. A la vez, la autosuficiencia alimentaria, la balanza comercial, el producto interno bruto agropecuario (PIBA) en relación al PIB nacional, PIBA per capita nominal y el salario por productividad, presentaron una tendencia significativa a disminuir, con lo que la base macroeconómica no será un pilar adecuado para mejorar la competitividad agropecuaria bajo el contexto analizado. La apertura comercial no ha repercutido en un incremento en la competitividad, pero puede ser mejorada dando prioridad a la soberanía alimentaria, fortaleciendo su mercado interno e invirtiendo en bienes públicos. The agricultural sector in Mexico is becoming less competitive, since there is a growing food import, which implies the existence of reduced ability to produce and distribute them in the market. The aim of this paper was to analyze macroeconomic indicators to quantify the competitiveness of agriculture in Mexico and its tendency, within a framework of trade liberalization. The revealed additive competitiveness was less than zero, with a decreasing trend. At the same time, food self-sufficiency, balance of trade, gross domestic product of agriculture (GDPA) in relation to GDP, per capita nominal GDPA and productivity wages, showed a significant tendency to decrease, so that, macroeconomic fundamentals will not be an appropriate pillar to improve agricultural competitiveness in the analyzed context. Trade liberalization has not resulted in increased competitiveness, but it can be improved by giving priority to food sovereignty by strengthening its domestic market and investing in public goods.

Abstract: A pesar de la pérdida en la producción de frijol, los productores continúan sembrando, pues no consideran el costo de oportunidad de su mano de obra, la tierra, y la depreciación de su maquinaria. Una probable explicación sobre la permanencia del cultivo, es que el apoyo de Procampo impacta en la rentabilidad de la actividad. Pero ante esta situación, surge la pregunta de si esto se podrá mantener ante la amenaza que representa la competencia con los productores de Estados Unidos, sobre todo a partir del a o 2008, cuando el frijol quedará libre de gravamen y podrá importarse libremente, y además está la conclusión de Procampo, que también será en el 2008.

Abstract: in order to grow ornamental plants in non-controlled environments, the effect of temperature on seedling emergence and growth must be known in order to optimize plant production. the aim of this research was to compare the growth of statice and viola seedlings, during the winter in the valley of mexico, under three production conditions: a polyethylene-covered tunnel, shade netting that cuts light transmission by 50 %, and in the open. we measured air temperature (0c), emergence percentage (e%), leaf area (la) per plant and dry weight biomass (dwb) per plant at 10, 18, 24, 31 and 35 days after planting (dap) in statice seedlings, and at 21, 28, 35, 43 and 52 dap in viola seedlings. in addition, the absolute growth rate (agr), the relative growth rate (rgr) and the net assimilation rate (nar) were calculated. compared to the outdoor treatment (control), the polyethylene tunnel and shade netting produced higher e% values: 95 and 93 % for statice and 97 and 95 % for viola, respectively. two different sigmoid curves of dry matter accumulation were observed in both species. the polythene tunnel produced higher dwb than the other conditions (p<0.05) with an average temperature of 19.5 0c and high thermal oscillation, but without frost. in the polyethylene tunnel, maximum dwb, la and agr (88 mg·seedling-1, 15.1 cm2seedling-1, and 7.4 mg·d-1, respectively) were observed at 35 dap in statice and 52 dap in viola (43.6 mg·seedling-1, 7.6 cm2 seedlingh and 2.4 mg·d-1, respectively) before transplanting. the polythene cover prevented temperatures below 0 °c, which explains the greater seedling growth in this environment.
