Root growth in an intercrop of pearl millet/groundnut

摘要: Abstract The growth of monocropped and intercropped pearl millet groundnut was studied during the 1978 rainy season in India. Washed cores soil a trench profile technique were used to measure root length spatial distribution roots. These measurements then analysed assess whether intercropping changed size system intermingling roots from two crop species occurred. Monocropped produced longer per unit ground area than (3500 m −2 compared with 2500 ) also rooted deeper (90 cm 70 cm). differed for monocrops while intercrop appeared intermediate both total its distribution. Observations made trenches confirmed greater indicated that adjacent rows mixing mid-way through growing season. This suggests interaction between crops may occur intercropping; it is unlikely, however, this major factor contributing increased yields measured experiment. Criteria assessing yield advantages are discussed briefly. Two different assessments showed resulted additional growth, later stages 10–15% more as monocrop.
