Tipología de productores de durazno en Zacatecas, México por atributos de calidad del fruto
Zacatecas se posiciona entre los cinco principales Estados productores de durazno en México. El durazno es criollo, amarillo, hueso pegado, pulpa firme, propagado sexualmente y cultivado en temporal en ˜ 81% de la superficie cultivada; lo que, destaca la baja competitividad de este cultivo. No obstante, por el número de productores dedicados a este cultivo, realza su importancia socioeconómica con relación a otros frutales. Si se pretende entender las características y problemáticas de las unidades de producción (UP) que sirvan como un instrumento para optimizar la asignación de recursos públicos, y proponer estrategias que mejoren el desarrollo de la agricultura, es necesario entender la heterogeneidad de los productores considerando sus características socioeconómicas dentro de las UP. Por ello, en esta investigación se buscó analizar y segmentar técnica y tipológicamente a los productores de durazno del estado de Zacatecas. Los datos se recopilaron a través de una encuesta a 204 productores de durazno en Zacatecas, México. Los resultados sugieren cuatro tipos de productores: 1) aquellos que plantan durazno sin objetivo; 2) los que plantan durazno a nivel de traspatio; 3) productores donde el durazno forma parte de un sistema de producción agropecuario; y 4) productores empresarios de durazno. En esta última categoría, se encontró ˜31% de los productores, lo cual podría explicar, en parte, la baja competitividad del cultivo ante otros sistemas productoPeer ReviewedPostprint (published version
Preferences in ‘Jalapeño’ pepper attributes: a choice study in Mexico
Background: According to Mexican growers of ‘Jalapeño’ peppers, its commercialization is the primary limitation. Thus, consumer knowledge is critical to develop added-value strategies. The objective of this study was to identify ‘Jalapeño’ quality attributes to determine consumer preferences and willingness to pay, based on socioeconomic characteristics. Methods: A nationwide face-to-face survey was carried out using the discrete choice experiment method. The survey included 1200 consumers stratified by gender, age and region. Results: Heterogeneity analysis using the probabilistic segmentation model revealed three types of consumers: A price-sensitive segment, non-demanding consumers without specific preferences and selective consumers with a preference shifted toward specific ‘Jalapeño’ characteristics. Thus, detail-oriented producers must compete through price strategies, based on the marketplace (markets on wheels, grocery stores, or supermarkets) and through some quality attributes preferred by selective consumers. Therefore, results suggest that farmers should grow the correct varieties with appropriate agronomic management to cope consumer preferences. Conclusions: This paper contributes to the growing body of the ‘Jalapeño’ literature by explicitly investigating consumer preferences and willingness to pay for them.Postprint (published version
Forage Productivity Evaluation and Geographic Information Systems in Temperate Semi-Arid Agro-Ecosystem
700,000 ha of the temperate semi-arid area of Zacatecas state are grown with rainfed crops. Low productivity is obtained from these crops: 350 kg/ha of beans grain and 500 kg/ha of corn grain. This state is characterized by a wide range of topographic and climatic values. A need for alternative crops led to establishment of a trial to evaluate rainfed forages, and to know in what range these could be located. Geographic information systems were used to find out the potential area of the species. Results indicated that sorghum presented a higher yield (5822 kgDM/ha) than sorghum x sudan (5460), pearl millet (4316), corn (3783), barley (3092), triticale (2638), wheat (2540), oats (1934) and beans (1243). Pearl millet presented the highest CP (16.5%) and lowest FAD (28.2%); and sorghum x sudan the lowest CP (6.5%) and highest FAD (38.7%). Sorghum (Sucro) produced 2.07 kg DM per each cubic meter of water evapotranspired, and for beans 0.5 kgDM/m3. Areas of low productivity potential for the traditional crop (beans) appeared as the medium potential areas for sorghum forage

New quality index based on dry matter and acidity proposed for Hayward kiwifruit
Researchers from various countries have proposed using dry matter at harvest as a worldwide quality index for Hay-ward kiwifruit, because it includes both soluble (sugars and acids) and insoluble (structural carbohydrates and starch) solids and doesn't change during post-harvest handling. Our consumer tests in 1999 and 2008 indicated that dry matter and ripe titratable acidity are related to in-store consumer acceptance of kiwifruit. In most California seasons, when ripe titratable acidity was less than 1.2%, only a dry matter greater than or equal to 15.1% was required for consumer acceptability. Our 6-year quality attribute survey of California kiwifruit at harvest and from cold storage demonstrated that dry matter and ripe soluble solids concentration were highly variable among vineyards and seasons, but ripe titratable acidity values varied more among seasons than between vineyards. Our results provide strong evidence that dry matter would be a reliable quality index candidate for California kiwifruit, especially if ripe titratable acidity were factored in

TECHNOLOGY ADOPTION OF DOUBLE LINE SEEDING ON A ROW WITH BASIN PLANTING SYSTEM IN MALTING BARLEY
The rainfed malting barley crop has been sown traditionally with the direct seeding system. This seeding system has led to runoff soil erosion problems and low productivity in Zacatecas, México. The Instituto Nacional de Investigaciones Forestales y Agropecuarias developed an alternative technology called double line seeding on a row with basin planting system (DLSRBPS) for this crop. The objectives of this study were to evaluate the extent of DLSRBPS adoption, characterize the technology users, and identify factors associated with the adoption of this technology in Zacatecas, México. The information was collected during 2009 and 2010 through surveys applied to 135 farmers in nine municipalities of Zacatecas. An adoption rate of 27 % for the DLSRBPS technology was estimated. Growers that adopted this technology had more experience in this crop, their educational level was higher than other farmer groups, and they planted a large area with this crop. Using the DLSRBPS technology, farmers noticed increased yields, reduced amount of seed at planting time and production costs. Lack of economic resources, limited availability of specialized agricultural machinery for the DLSRBPS technology, and little or no technical assistance were the main limiting factors for using the DLSRBPS technology in Zacatecas

Partial Root-Zone Drying Technique: from Water Saving to the Improvement of a Fruit Quality
Due to climate changes and increased demands of different water users (agriculture, industry, domestic) water becomes scarce resources worldwide. Since irrigated agriculture is the one of the largest consumer of these resources (so-called blue water footprint), irrigation management must be shifted from maximal production per crop area to maximal production per unit of water used by crops. Among the strategies for reducing water footprints, changing the full irrigation to the reduced crop's water supply (deficit irrigation techniques) is one of the options. In this mini-review, we present the latest advances of partial root-zone drying (PRD) applications in different agricultural plants, with the special emphases on the PRD effects on increasing WUE, yield and yield quality. We describe two PRD practical approaches (alternate and fixed), BACKGROUND: of PRD induced increase in yield and water use efficiency and improved understanding about nutrient use efficiency. The evidence of PRD effect on the increase in nutritional and health attributes of yield in different species is also presented. Because of limited available data, further research is needed to understand complex biosynthetic pathway and synthesis of nutritive- and health-related metabolites and antioxidants in PRD-treated plants. Practical application and promotion of this knowledge will allow farmers in water scarce areas to adapt PRD not only as a strategy for saving water, improving nutrient use and increase/sustain yield, but also for producing food with enhanced nutritive and health characteristics
