The growth of pearl millet and groundnut singly or intercropped was studied during the 1978 rainy season in India. Washed cores of soil and a trench profile technique were used to measure the root length and spatial distribution of roots. Root length/unit ground area was 3500 and 2500 m/m2 and root depth was 90 and 70 cm in monocropped millet and monocropped groundnut, resp. The distribution of root length also differed for the 2 monocrops while the intercrop appeared intermediate both in total length and distribution. Observations made in trenches confirmed the greater length of the millet root system compared with the groundnut and showed that roots in adjacent rows of millet and groundnut in the intercrop were mixing midway through the growing season. Methods for assessing yield advantages of intercropping are compared and it was calculated that intercropping gave a 10-15% increase in root length compared with the monoculture
