EFFECT OF GREYWATER (SOAP WATER) IRRIGATION ON GROWTH AND ROOT NODULES OF MEDICINAL PLANT (SESBANIA GRANDIFLORA) L.

Abstract

Present study was conducted to evaluate the effect of household greywater (soap water) on growth of Sesbania grandiflora L. The plants were grown in sandy loam soil irrigated with soap water solutions (C = 0g/L, T1 = 0.5g/L and T2 = 1.0g/L). Significant increase in growth parameters (root length, shoot length, fresh and dry weights of root, shoot and leaves) was observed with application of T1 followed by T2 over control. Root nodules were significant increased under T1 followed by T2. Larger size nodules were found more in T1 compared to T2 and the control. The results demonstrated that utilization of greywater is beneficial for the cultivation of Sesbania grandiflora L. under scarcity of fresh water irrigation.
