Root distribution and water uptake patterns of individual chilli pepper (Capsicum annuum L. ’Long Slim Cayenne’) plants growth in 1-m-high soil columns in plastic cylinders were examined under irrigated and nonirrigated conditions. Roots were able to grow through the soil profile and consequently extract water from a soil which was conducive to root growth. Water uptake occurred both in the irrigated and in the nonirrigated treatment throughout the soil profile. Uptake was highest in the top 0.50 m of the former and was a result of greater water availability rather than lack of root growth at greater depths. Chilli pepper plants can, under droughty conditions, extract subsoil moisture.Key words: Chilli pepper, soil moisture, water uptake, root growth
