EFFECTS OF PHOSPHORUS/NITROGEN RATIOS ON ROOTINGRESPONSE OF MUNG BEAN (PhaseolusaureusRoxb.)CUTTINGS

Abstract

Abstract :The effect of phosphorus (P) and nitrogen (N) on the rooting response of mung bean (PhaseolusaureusRoxb.) cuttings was studied. A wide range of P concentrations (8-62 mg/L) was used as well as for N (75-400 mg/L) separately and in combinationsat different ratios. The optimal rooting response,(20.34) roots per cutting, was obtained by the combination of (20:250 mg/L) P:N.Keywords: Mung bean, phosphorus, nitrogen, rooting response, mineral nutrition.
