Microclimatic interactions in agroforestry systems uri icon

abstract

  • The interaction of the components of an agroforestry system with elements of microclimate is presented in terms of the interception by foliage of radiant energy and of rainfall; and of the temperature, humidity and windspeed of air surrounding the foliage. Most of the measurements reported are from a trial in which pearl millet was grown at ICRISAT, Hyderabad, between hedges of Leucaena leucocephala Lam. In terms of microclimate, the main advantage of the alley system was to intercept more light throughout the year and therefore to produce more biomass. Temperatureand humidity within the alleys differed little from values in the open but windspeed was substantially less. The main disadvantage of the system in terms of pearl millet production was therefore competition below ground rather than above
