Potatoes are the most important root and tuber crop in the worl and is farm in more than 125 countries (NeBambi et al., 2009). The potato is a crop sensitive to drought and high temperatures. Therefore, in the face of accelerated climate change, measures are urgently needed to reduce the effects of drought and thermal stress on potato crops. The mulch reduce the thermal amplitude and retains moisture in the soil. The objective of this work is to evaluate whether the presence of grass mulch in different thicknesses offers a higher yield and a reduction of the physiological effects related to thermal and water stress in the potato crop “Solanum tuberosum“. The plant material used was sprouted tubers of potato variety “Canchán“, sown directly in enriched soil and subjected to poor controlled irrigation. The experimental design used was a completely randomized block design (DBCA), 120 potato plants were grown, separated into three blocks with four treatments and ten repetitions during a period of 120 days. The response variables were plant height, number of stems, number of leaves, root length, dry weight, fresh weight, chlorophyll analysis, proline analysis, additionally the geotemperature and gravimetric humidity were evaluated at different depths. The data obtained were analyzed by simple analysis of variance (ANOVA), Tukey's test and / or Friedmann's test, where significant differences were obtained in several variables with respect to the applied treatments. It was concluded that the best thickness of dry grass mulch to reduce drought and thermal stress is 5 cm and 7.5 cm thick, in addition to the variables dry weight of leaves, stem and concentration of foliar proline, are good indicators of the degree of incidence of stress
