DELGADO RAMIREZ, Gerardo et al. Evaluation of technology to maximize the production of chile serrano in the Region Lagunera. Rev. Mex. Cienc. Agríc [online]. 2014, vol.5, n.8, pp.1557-1565. ISSN 2007-0934.

Mexico has an extensive genetic diversity of green chile with about 40 varieties. The chile serrano is a favourite for fresh consumption for making sauces. For its adaptability, chile serrano is produced in regions that cover a wide range of environmental conditions; however, yields achieved are contrasting by the different levels of technology applied. In the Lagunera region of Coahuila and Durango, the average yield reaches 65% of the state average with the highest production of this vegetable. However, previous studies with other crops have shown that it is possible to reach and even surpass the highest producing States using improved varieties in combination of techniques such as drip irrigation and plastic mulch. The aim of this study was to evaluate technology to increase production, productivity and profitability of growing chile serrano in the Lagunera Region. We tested the commercial hybrids Camino Real F1, Montero and Arista F1, as well as some strategies to precisely control the water regime in chile serrano grown with drip irrigation and plastic mulch. These strategies involved the use of two methods for calculating water consumption and two alternatives for the placement of the irrigation tract. The results indicated that, the factors studied significantly affected yield, water use efficiency and fruit quality, achieving comparable or higher yields than those recorded in the States with the highest production.
