Selection of forage pigeon‐pea (Cajanus cajan (L .) Millsp) lines for soil decompaction

摘要

According to Camargo & Alleoni (1997 ), pigeon‐pea plays an important role among species fit to promote soil decompaction, due to the capacity of its roots to penetrate highly compacted soil layers.Since differences not only among species but also within species have been observed for this character, selection within a species like Caj anus caj an seems to be an excellent aid to help solving the problem of soil compaction.This work had the purpose of selecting,among forty pigeon pea pure lines, the most efficient genotypes to promote soil decompaction.
