ALVAREZ DIAZ, Paulino A. et al. Production systems of malting barley (Hordeum vulgare L.) in Zacatecas state, Mexico. Agric. Téc. Méx [online]. 2006, vol.32, n.2, pp.181-190. ISSN 0568-2517.

In order to know the production systems of malting barley in the state of Zacatecas, a diagnosis study was carried out by direct interview to 48 farmers following a questionnaire based on the evaluation of market chains. Data was gathered on 194 variables and submitted to multifactorial and cluster analysis. Three production system were defined whose main characteristics for System I were: 50 years average age, education up to elementary school, 43 ha of land property and cultivation of 81 ha, low irrigation availability, method of sowing without rows and soil corrugationsm, average yield, 1.6 t ha^-1, 10-30% of grain not suitable for malting, profit/cost ratio, 1.7. For System II: 40 years average age, education up to high school, 50 ha of land property and cultivation of 82 ha, method of sowing without rows and soil corrugations, yield from 1.5 to 2.5 t ha^-1, 10% of grain not suitable for malting, profit/cost ratio, 1.7. For System III: 36 years average age, education up to baccalaureate, 215 ha of land property and cultivation of 250 ha, precision sowing average yield, 1.8 t ha^-1, 5% of grain not suitable for malting, profit/cost ratio, 1.45. The productivity of the systems was directly related to farmer's level of education, and the sowing method used, and inversely related with farmer's age.
