Resumen

The research was carried out to define the value of the environmental indicators, and the general index of environmental sustain-ability of the production units of hard yellow corn (MAD) in the Pativilca valley, Peru. 73 surveys with structured questions in the environmental dimension were applied. To determine the Environmental Impact Coefficient (EIQ) and the Environmental Impact (IE), the EIQ values were obtained for the active ingredient of 12 pesticides, then the proportion of use in the field was calculated to obtain the value of environmental impact in the field. To define the levels of environmental sustainability, multicriteria analysis methodological tools were used. The data were ordered on a value scale of 1 to 5; 1 being the least sustainable value and 5 the ideal sustainability value. An IE ha–1 of 101.11 was found, a value that represents a high negative impact on the population and the environment due to inadequate practices in handling agrochemicals. The soil management and conservation, pest management and water management subindicators are the ones with the least contribution in the operation of agricultural systems, as a consequence, the environmental sustainability index with 2.54 presents a very low level in the sustainability scale established in the study by not reaching the minimum acceptable threshold of sustainability.
