Effect of leaf and bark aqueous extract of Anogeissus latifolia on growth performance of Vigna unguiculata

The present study was carried out to assess the effect of leaf and bark aqueous extract of Anogeissus latifolia tree on Vigna unguiculata traditional crop to understand the suitability of treecrop combination in agricultural fields. Different concentrations of leaf (1%, 3% and 5%) and bark (1%, 3% and 5%) aqueous extract of A. latifolia were used to study radicle and plumule growth of V. unguiculata. The leaf and bark aqueous extract have shown minimum allelopathic effect on V. unguiculata and suppressed/stimulated radicle and plumule growth under different concentrations. The wide distribution of A. latifolia in a sub-tropical region of Garhwal Himalaya, provides good fodder fuel wood and timber to the villagers. Therefore introducing Anogeissus latifolia in agricultural field and maintaining the existed trees at boundaries of agricultural fields can be useful to the villagers requirements and wherever the possible allopathic effect exit can be minimized by lopping the branches of trees and use of naturally flecked off bark for fuel wood purposes.
