“…Poorly drained soils cause stress in the root system due to the lack of oxygen, leading to a reduction in the productivity and/or death of the plants. In addition to excessive moisture, pecan trees are sensitive to saline soils (GRAGEDA et al, 2011). …”

Given the increasing investment in the pecan production in southern Brazil, it becomes necessary researches, assisting in solve problems and proposition of technical and methodology to enhance this production chain. Thus, the present review aimed to survey the existing information about the culture, both on the world and the Brazilian scene. Issues related to botany, climate and soil requirements, alignment and planting density, cultivars, pests and diseases, among other technical aspects of this culture will be addressed. Pecan nut presents nutraceutical properties that are beneficial to human health, which has increased its demand from consumers. However, there are few research results with pecan nut in Brazil and there are many gaps in scientific knowledge about this culture, especially as regards the management of pests and diseases control, irrigation and nutrition, in Brazilian conditions.

Palabras clave: Carya illinoinensis, metales, pH, nitratos, calidad del agua RESUMEN El cultivo de nogal pecanero es muy importante por su impacto económico en la región norte de México. La aplicación de agua en las huertas proveniente de pozos agrícolas con alto contenido de sales propicia su acumulación en el suelo, dificultando su movilidad hacia las raíces de los árboles. Con el propósito de analizar químicamente la composición del agua de riego en la región nogalera del sur de Chihuahua y contrastarla con las normas mexicanas vigentes se realiza la siguiente investigación. El muestreo se llevó a cabo el 25 de junio del 2014, se seleccionaron 10 huertas de nogal pecanero del sur del estado de Chihuahua y se tomó una muestra de agua de cada pozo. Los parámetros analizados fueron pH, cloruros, Fe, Mn, Zn, Cu, As, B, Pb, Cd, Ni, Na, sólidos disueltos totales, nitratos, dureza y alcalinidad, relación de absorción de sodio y conductividad eléctrica (CE). Para uso y consumo humano se consideró la Norma Oficial Mexicana 127, mientras que para riego agrícola se utilizó la Ley Federal de Derechos y Disposiciones Aplicables en Materia de Aguas Nacionales. Se obtuvieron valores dentro de los parámetros establecidos tanto para agua de consumo humano como en agua de riego en el sur del estado de Chihuahua, siendo dicha agua de buena calidad. Sin embargo, se sugiere tener un monitoreo periódico de las concentraciones de Pb, Ni, As, B y CE para evitar afectar a la población humana de comunidades circundantes en la región, así como impactos negativos en la actividad agrícola.Key words: Carya illinoinensis, metalles, pH, nitrates, water quality ABSTRACT Cultivation of pecan nuts is very important for the economic impact in the northern region of Mexico. The application of water in the orchards from agricultural wells with high salt content, promotes their accumulation in the soil, hindering their mobility to tree roots. In order to chemically analyze the composition of water irrigation in the pecan-producing Rev.

Pecans are cultivated extensively in the Yaqui Valley, Sonora. These soils often have problems of salinity and high concentrations of exchangeable sodium, which cause a decline in pecan productivity. At the end of the season of irrigation with water from the system of reservoirs on the Yaqui River, groundwater is generally used from May to August. This can result in salt accumulation in the soil when water is of poor quality. Gypsum has been used as an amendment to rehabilitate soil by improving its physical and chemical properties. The main objective of this study was to investigate the effect of gypsum application to a saline soil of a pecan orchard in the Yaqui Valley. Rehabilitation was carried out for two consecutive years. In the first year a dose of 5 and 10 Mg ha‑1 was applied, while in the second year 2 Mg ha‑1 of gypsum was used. Two ridge washings were done after each aplication. The physico-chemical analyses of the soil were conducted following NOM-021-RECNAT-2000 during three years prior to and after the applications of amedment. Once the amendement was applied, the values of electrical conductivity decreased from 12.41 to 6.29 dS m-1, percentage of exchangeable sodium from 12.48 to 5.57 and sodium adsorption ratio from 10.54 to 4.88 at the depth of 0-30 cm. The use of agricultural gypsum and washing in a saline soil of the pecan orchard improved soil chemical properties using 5 and 10 Mg ha-1.
