摘要：Species and density of green manures intercropped with maize modify the patterns of interspecific competition, which may alter the responses of temperature and soil moisture. This study analyzed the effects of Crotalaria spectabilis and Cajanus cajan on soil temperature and moisture along the development stages of maize grown in intercropping in an organic system. The experimental design was randomized blocks with four replications. The treatments consisted of three maize intercropping: MC - Crotalaria spectabilis (5 plants m -1); MG - Cajanus cajan (5 plants m -1); MCG - Crotalaria spectabilis and Cajanus cajan (10 plants m -1, five plants of each green manure), sown in the maize row and three control treatments: M - maize; C - Crotalaria spectabilis and G - Cajanus cajan, single. Soil temperature readings were taken in the row and between the sowing rows, and soil moisture readings in the maize sowing row at 8, 12 and 17 hours, in V5, V8, VT, R2, R4 and R6 phenological stages. The evaluation depths were 0-0.10, 0.10-0.20 and 0.20-0.40 m. The times, the depths and the line-between-row positions influenced the soil temperature, while the depths and the phenological stages influenced the soil moisture retention capacity. Intercropping reduced soil temperature, especially MG, which also reduced soil moisture between V8 and R2 maize stages.
