SUMMARY
The fertilizer value of several plant residues as sources of organic matter for the bean plant (Phaseolus vulgaris L.) was compared. It was noticed in this field trial that the incorporation of non-decomposed stems and leaves of white lupine (Lupinus algus L.) to the soil one day prior to sowing beans resulted in plants with longer internodes than the controls. This effect of the white lupine vegetation was further tested in two varieties of beans in a pot experiment, in comparison with kudzu (Pueraria thunbergiana (Sieb. & Zucc.) Benth) and jackbean (Canavalia ensiformis (L) DC).
The results of the experiment showed that non-decomposed white lupine stems and leaves added to the soil induced more elongation of the stems of the two bean varieties tested than that recorded for the controls; the var. Pintado (undetermined growth) gave a stronger reaction than Goiano (determined growth). The vegetation of jackbean had a slight effect on stem elongation of the bean test plants, but kudzu had none.
The best response was obtained when 200 g of white lupine stems and leaves were incorporated in the soil used to fill the pots. Pintado bean plants grown in these pots were on an average 47 cm taller than the controls.
