Some indigenous cropping systems of Eastern Nigeria

Se revisan brevemente los sistemas de cultivo en uso por los agricultores campesinos de la region del sudeste de Nigeria. Se recomienda un sistema de cultivo basico tradicional de tipo rotacional, con una fase cultivable de 2 anos, seguida por uno o mas anos de arbusto natural en barbecho. En esta parte de Nigeria, localizada en la zona de bosque humedo tropical, las raices tuberosas dominan los sistemas de cultivo; los demas cultivos, granos y hortalizas ocupan una posicion secundaria. Por una combinacion de varios factores, se ha alterado la rotacion tradicional de cultivos y se han desarrollado numerosas variantes que estan en uso en las diferentes zonas agricolas de la region.

The cropping systems in use by the peasant farmers in the Southeastern region of Nigeria have been briefly reviewed. A basic traditional rotational cropping system with a 2-year arable phase, followed by one or more years of natural bush fallow, is postulated. In this part of Nigeria, which lies in the rain forest zone, tuberous root crops dominate the cropping systems; all other crops, grains and vegetables occupy a secondary position. Because of a combination of several factors, the immutability of the traditional arable rotation has been challenged and numerous variants have been developed and are in use in the different agricultural zones of the region.
