The level of productivity of the hard yellow corn crop, cultivated mainly in the coastal region of Ecuador, registers increases due to technological advances. The technology for the production of corn allows to improve its productivity if it is used correctly; however, various agro-socio-economic factors limit its adoption. In this work, the level of adoption and the factors that affect the use of new technologies for the cultivation of hard corn are established through a semi-structured questionnaire applied to 150 farmers with a scale of variables with three intervals and the calculation of the index of adoption. In Ecuador, the level of technology adoption is high for seed, disease management, and weed control, while soil analysis, crop rotation, nutrition, and direct seeding present a low degree of adoption since producers, based on their experience, modify doses and frequencies in order to reduce costs. The agro-socioeconomic factors that present significant differences in adopting technology are the cost of production followed by the offer of technological packages, training and credit. In addition, farmers demand new technologies from institutions such as irrigation infrastructure, organic waste management and precision agriculture.
