Abstract

Intercropping aims at sustainable maximization of soil and water use, and has become an alternative for regions with relatively short rainy periods and high temperatures. The aim was to verify the dynamics and maintenance of soil moisture as a function of soil temperature oscillations in intercropped maize systems with and without irrigation. The experimental design was composed of twelve treatments: maize, brachiaria and crotalaria in monoculture, intercropping between maize and brachiaria, intercropping between maize and crotalaria, and uncovered soil, in two systems (six irrigated treatments and six without irrigation), with four replications. Soil temperature at depths of 10, 20, 30, and 40 cm and soil moisture in the 0-30 cm layer were evaluated. The production components of maize at the end of the cycle were evaluated. Maize intercropped with crotalaria or brachiaria provided a 17.4 and 17.6% reduction in average soil temperature, respectively. Intercropping reduced the temperature range of the soil when compared to maize in monocrop. Soil moisture showed lower values at the development, intermediate, and final stages for the intercropped maize crops. Maize under irrigated intercropping showed no significant difference in yield when compared to monocropping.
