In this study, two hydroponic experiments were conducted in nutrient solution growth system. Experiments were conducted in growth chamber of Erciyes University, Agricultural Faculty in Kayseri, Turkey. In the first experiment, 10 local Turkish bottle gourd genotypes and two commercial watermelon cultivars were screened under 2 N doses (0.3 mM and 3.0 mM N) in RBD design with three replications for six weeks. In the second experiment, four genotypes (N-efficient: 70-07 and 07-45, N-inefficient: 35-10 and 45-07) were selected and used as rootstock for grafting with N-inefficient watermelon cultivar (Crimson Sweet) under 2 N doses. The grafted N-efficient gourd genotypes (07-45 and 70-07) significantly contributed to growth and biomass production of the N-inefficient watermelon plants as compared to non-grafted control plants and thus showed a higher rootstock potential for watermelon. The N-efficiency of some gourd genotypes was associated with vigor root growth and active root system particularly at low N conditions. These traits could be useful characters to select ‘N-efficient’ bottle gourd rootstocks for sustainable agriculture in the future.

To test the hypothesis that root growth at depth is a key trait explaining some genotypic differences in drought tolerance in potato (Solanum tuberosum L.), two varieties (Horizon and Maris Piper) differing in drought tolerance were subjected to different irrigation regimes in pots in a glasshouse and in the field under a polytunnel. In the glasshouse, both cultivars showed similar gas exchange, leaf water potential, leaf xylem ABA concentration and shoot biomass independently of whether plants were grown under well watered or water deficit conditions. Under well watered conditions, root growth was three-fold higher in Horizon compared with Maris Piper, 3 weeks after emergence. Water deficit reduced this difference. In the polytunnel, applying 60% or less irrigation volume compared with full irrigation significantly decreased tuber yield in Maris Piper but not in Horizon. This was coincident with the higher root density of Horizon in deep soil layers (>40 cm), where water content was stable. The results suggest that early vigorous root proliferation may be a useful selection trait for maintaining yield of potato under restricted irrigation or rainfall, because it rapidly secures access to water stored in deep soil layers. Although selecting for vigorous root growth may assist phenotyping screening for drought tolerance, these varieties may require particular environmental or cultural conditions to express root vigour, such as sufficiently deep soils or sufficient water shortly after emergence.

Objetivo: Establecer una línea base como fundamento para la intervención e inducción de innovaciones a través de escuelas de campo y planes de negocios. Diseño/metodología/aproximación: El estudio se desarrolló en San José del Carmen, San Cristóbal de Las Casas, Chiapas, México. Se elaboró una encuesta como instrumento para recabar en campo información de familias de la localidad con la finalidad de conocer su situación actual. La localidad de trabajo se eligió utilizando como criterio las poblaciones que se encuentran dentro de Cruzada Nacional contra el hambre y en la clasificación de la pobreza extrema Resultados: La localidad de San José del Carmen es considerada como de alta marginación, la población es bilingüe, su principal lengua es el Tzotzil, el nivel de estudios promedio es hasta el tercer año de primaria, las principales actividades productivas son la siembra de maíz (Zea mays L.), frijol (Phaseolus vulgaris L.), papa (Solanum tuberosum L.) y haba (Vicia faba L.) que son utilizadas principalmente para autoconsumo.  No cuentan con agua potable ya que su sistema es a través de la recaudación de agua de lluvia o a través de un jagüey. Sus principales actividades económicas son la albañilería por parte de los hombres, y venta de productos, tales como el pozol (bebida energética a base de maíz y cacao (Theobroma cacao L.), tostadas y algunos vegetales por parte de las mujeres. Las tostadas son producidas en forma artesanal con un proceso de doble nixtamalización y vendida en bolsas de 20 tostadas cada una, a un costo de MX$10.00 en los mercados de San Cristóbal de las Casas, una a dos veces por semana alrededor de 40 bolsas por día de venta. Limitaciones del estudio/implicaciones: La afiliación zapatista de alguno de los pobladores y el hecho de que algunos habitantes no hablen español, fueron factores que limitaron desarrollar al 100% el estudio; sin embargo, se considera que se tienen los elementos necesarios para establecer la línea base de la situación de San José del Carmen. Conclusiones: El diagnóstico servirá como una herramienta para establecer una intervención a través de innovaciones y planes de negocios en la comunidad de estudio. Los pobladores cuentan con herramientas necesarias para obtener nuevos conocimientos que ayuden a un desarrollo de su producción. El idioma no deberá de ser una limitante para ello.
