Evaluation of Pigeon Pea Lines for Biological Soil Decompaction

open access: yesInternational Journal of Agronomy, Volume 2009, Issue 1, 2009., 2009
Soil decompaction is generally achieved through mechanical cultivation practices; however biological processes can significantly add to this process through root growth, development, and later senescence. This study was carried out in Piracicaba, SP, Brazil and had the purpose of selecting, among forty one pure pigeon pea lines, the most efficient ...
