AGUIRRE ORTEGA, Jorge et al. Edafoclimatic effect on the development of agroforestry and silvopastoril modules in Nayarit’s Coastal Plain, Mexico. Zootecnia Trop. [online]. 2008, vol.26, n.3, pp.309-313. ISSN 0798-7269.

Agroforestry systems in Latin Americas have been important, especially in Mexico. Nayarit has a great potential for the farming-forestry development, where woody species interact with traditional culture components (annual and perennial plant cultures, and animals) bringing in an integrated system. The objective was to evaluate the adaptation and development of eight agrosilvopastoral species (amapa, mahogany, cedar, guanacaste, melina, paulonia, primavera, and teak) intercropped with sorghum in a sandy coastal ecosystem. In a mixed plot, the same tree species plus four fodder trees: guaje, guajillo, cacahuananche, and capomo associated with two herbaceous legumes: frijolillo and mucuna, and guinea grass. Study was conducted at Puerta de Mangos de Santiago Ixcuintla, Mexico. The following forestry variables were measured: plant height and stem and crown diameter, while in the fodder plants, height and biomass yield were measured. The results obtained for plant height in the timber groups indicated differentiated groups of fastest growing (P>0.05) among treatments. The difference between groups also showed for stem diameter and cup, height to first branch, number of branches and leaves; Sorghum yield was unstable. It was attributed to the negative effect of water-saturated on low drainage clay soil the primavera extinction, prevalence of stem borer in cedar, and maturity and low yield of grain sorghum. The mixed plot located in a lower portion caused higher loss of timber trees and disappearing of paulonia and primavera. Same results occurred with the creeping legumes and grass. Except capomo, the other trees tolerated floods. Biomass yield of guaje surpassed statistically the rest, but with productive differences between seasons.
