In Mauritius, many food crops are grown in the sugarcane interrows. These crops are planted after a previous cane crop has been harvested and may compete with the new cane crop for light, water and nutrients. The degree to which the interrow crop has a detrimental effect on the cane yield is an important aspect of this type of cropping system. Measurements of the amounts of light intercepted and water transpired by plant sugarcane (cv. R570) and an interrow crop of maize (cv. UR22) are given. Concurrent measurements of direct soil evaporation are also presented and shown to be a substantial portion of the total evaporation from the mixed crop, especially when the canopy cover is low. The comparatively slow development of the plant cane canopy led to low light interception and a very small surface conductance. Conversely, the maize canopy developed rapidly and, despite having lower stomatal conductances than the cane at the beginning of the season, it intercepted much more of the light and transpired most of the water used by the mixed crop may have been adequately irrigated at the beginning of the season and under-irrigated later in the season. | |
