During recent seasons, drought has caused losses of 50 % of potato production in several countries in Central America. Knowledge and use of varieties tolerant to drought is a key to increase potato production and yield under stress conditions. The experiments were done in the Research Institute of Tropical Roots and Tubers Crop (INIVIT) during the months of December 2014 to March 2015. Ten plots per variety were planted; half of them (five) was withdrawn irrigation to after 50 days after planting for 20 days (period of drought stress) irrigation restarting after 70 days. At the harvest time it was determined: the Stress Susceptibility Index (SSI), Stress Tolerance Index (STI ), Tolerance Index (TOL), Mean Productivity ( MP) and Yield Stability Index (YSI ). Atlas and Maranca varieties have the lowest values of SSI, with 0,67 and 0,61 respectively, and the highest values of STI, with 0,79 and 0,81 respectively. MP recorded the highest was in the Atlas variety, with 19.92 t/ha. Higher values of YSI belong to Atlas and Maranca varieties, with 81,07 and 79,29 % respectively.

The paper addresses the social impact of scientific research, conducted by the Engineering Agroindustrial Processes in the municipality of Rhodes during the period 2012-2013. The main results obtained relate to a process consisting of three stages: diagnosis, impact measurement and evaluation of results. The first stage includes a description of the municipality and classified by subject and research bodies of the territory, of agreements to set it proposed instruments. In the second, through variables (joint research with reality, knowledge and innovation in the implementation of the results and impact of the research management in the municipality) and a set of indicators for each of them, the social impact that research has on the development of the territory is measured. In the third step an evaluation of the results of each variable and indicators is performed. The method, validated by expert consensus, ensuring an assessment with regard to the relevance, feasibility and applicability of them, allowing local governments to draw scientific and management policies in line with the needs and priorities identified in the local environment.
