“…The remainder of the designated area received nonlabeled (NH 4 ) 2 SO 4 by hand application at the grower's fertilization rate (N at 373 kg•ha -1 ) and schedule. The recommended N application rate for pecan in New Mexico is 168 to 224 kg•ha -1 (Herrera, 1995). The 15 N-labeled ammonium sulfate (ISOTEC, Miamisburg, Ohio) had a total N content of 20.9% and a 15 N content of 10.4 atom percent.…”

From March through June 1996, 15N-labeled fertilizer was applied to mature pecan trees [Carya illinoinensis (Wangehn.) K. Koch] in a commercial orchard to determine the fate of fertilizer-N in the tree and in the soil directly surrounding the tree. The concentrations of 15N and total N were determined within various tissue components and within the soil profile to a depth of 270 cm. By Nov. 1996, elevated levels of 15N were greatest at depths just above the water table (280 cm), suggesting a substantial loss of fertilizer-N to leaching. Recoveries of 15N from tissue and soil at the end of 1996 were 19.5% and 35.4%, respectively. Harvest removed 4.0% of the fertilizer-N applied, while 6.5% was recycled with leaf and shuck drop. In 1997, with no additional application of labeled fertilizer, the tissue components continued to exhibit 15N enrichment. By the end of the 1997 growing season, 15N levels decreased throughout the soil profile, with the most pronounced reduction at depths immediately above the water table. Estimated recoveries of 15N from pecan tissue (excluding root) and soil at the end of 1997 were 8.4% and 12.5%, respectively. In 1996 and 1997, 15N determinations indicated an accumulation of fertilizer-N in the tissues and a loss of fertilizer-N to the groundwater. Early spring growth, flowering, and embryo development used fertilizer-N applied the previous year, as well as that applied during the current year.

“…In the 90's approximately half of the improved varieties that were planted in the USA corresponded to Stuart, Western Schley and Desirable, with 22, 14.6 and 10.9% respectively. During this period, the main varieties sown for commercial production in the western region of the USA (Burns et al, 1990;Herrera, 1995;Wells, 2017a) and northern Mexico (Núñez et al, 2001;Orona-Castillo et al, 2006) were mostly "Western Schley" and "Wichita" the latter is used mainly as a pollinator, due to the incomplete dicogamy of the species. From 2010 to 2014 the planting of 14 to 30 different cultivars was reported in Georgia, the main producing state of the USA, with…”

Pecan is a North American native tree that produces a stone fruit or kernel, commonly known as pecan nut,which is highly valuable worldwide due to its sensory quality, and health promoting properties derived from the presence of mono- and polyunsaturated fatty acids, tocopherols and monomeric and polymeric polyphenolic compounds. The increase in the demand for pecan nut leads to an increase in by-products such as leaves, cake and principally nutshell, which have high contents of bioactive components, making them interesting raw materials to produce nutraceuticals with health benefits. The phytochemical content of pecan oil and kernel, as well as that of the main pecan by-products is discussed in detail, paying special attention to the presence of individual polyphenols with monomeric and polymeric structures. Finally, studies regarding the biological activity and potential use of pecan oil, kernel and by-products are summarized and discussed.

“…Otra diferencia está referida al tipo de riego utilizada en su cultivo. En la Comarca Lagunera 92% de los huertos riegan con agua proveniente de presa, en Jiménez, Chihuahua este tipo de riego es 15% y en Hermosillo, Sonora se riega sólo con agua bombeada del subsuelo (Herrera, 1995;Medina y Cano, 2002).…”

México es el segundo país productor de nuez pecanera y el primer exportador de este producto en el mundo. Con el objetivo de proponer acciones para favorecer la productividad de esta actividad, se caracterizó el funcionamiento de su producción y comercialización en tres de las zonas productoras más importantes de nuez en México: la Comarca Lagunera, Hermosillo, Sonora y Jiménez, Chihuahua. Para lo anterior, se formularon dos tipos de cuestionarios aplicados en los años 2014 y 2015. Uno se aplicó a una muestra de productores determinada aleatoriamente. El segundo se dirigió a comercializadores-transformadores del producto. Los resultados mostraron que los tamaños de huerto predominantes para la Comarca Lagunera y Jiménez son menores que los de Hermosillo, donde son hasta de 800 ha. El número de plagas es mayor en la Comarca Lagunera y Jiménez. En Hermosillo, además, el productor cuenta con mayor infraestructura para manejar el cultivo y los productores reciben mayor asistencia técnica y financiera, lo que explica los mayores rendimientos obtenidos. En el aspecto de comercialización-transformación, el número de empresas es mayor en Jiménez, seguido por Comarca Lagunera y al final Hermosillo, región que comercializa nuez hacia China directamente por los productores. Se concluye que, para mejorar la producción en la Comarca Lagunera y Jiménez, Chihuahua se requiere atender aspectos de organización, capacitación y financiamiento, y para mejorar la comercialización en las tres zonas de estudio es necesario crear un sistema de información de precios y empresas que le permitan al productor vender al mejor precio.
