Study on the production of wheat technology per agro-system, for pointing out needs of information. Rev. Mex. Cienc. Agríc [online]. 2014, vol.5, n.8, pp.1351-1363. ISSN 2007-0934.

Great vision technology generated in the experimental fields may have biases in reality, which can reduce their efficiency and effectiveness. In southern Sonora, stratification production environment is a function of soil type, which can distinguish two main contrasting scenarios; Entisols (alluvium) light in the river bed, heavy on the sides and in flood zones, and Vertisols (clays) dominated by clay; nearby are deeper, then compacted and finally the stony ones. In each of these agro-systems, information on management practices in wheat were collected during 2007 and 2010. With this information, a correlation analysis, stability analysis and, a stepwise regression were performed. In alluvial soils, expanding the range of risks adversely affected yields and the opposite happened in stony clayed soils. Delaying the planting date affected yields in clay soils. The probability of response to additions of phosphorus was low, except in compacted clayed soils. Insecticide applications were on time in alluvial soils, these were flawed in stony clayed soils. Dragging is the only practice that allowed alluvial soils, in the rest it affected adversely the production. In compacted clayed soils, dragging negatively affected wheat production. To the extent that habitat productivity was higher, the quantified variables were less predictable, probably because of the higher availability of information.
