Abstract

A pot experiment was conducted to study the response of high yield variety of Vigna radiata (Mung bean; Var. Pusa-105), after fertigation with distillery effluent (DE) in two seasons, that is, rainy and summer season. The DE irrigation produced significant (P<0.001) changes in electrical conductivity (EC), pH, organic carbon (OC), sodium (Na+), potassium (K+), calcium (Ca2+), magnesium (Mg2+), iron (Fe2+), total Kjeldahl nitrogen (TKN), phosphate (PO43-), sulphate (SO42-),  zinc (Zn), copper (Cu), cadmium (Cd), manganese (Mn) and chromium (Cr) of the soil. The non-significant (P>0.05) changes were observed in water holding capacity (WHC) and bulk density (BD) of the soil in both seasons. The agronomical performance of V. radiata was gradually increased from 5 to 50% concentrations of DE in the rainy season and 5 to 25% concentration of DE in the summer season, while it was decreased at higher concentration, that is, from 75 to 100% concentrations of DE in the rainy season and 50 to 100% concentrations of DE in the summer season in comparison to the control. The maximum growth of V. radiata at maturity stage was observed at 50% concentration of DE in the rainy season and at 25% in the summer season. The contamination factor (Cf) of various metals were in order of Mn>Cd>Cr>Cu>Zn for soil and Cr>Cu>Zn>Cd>Mn for V. radiata in both seasons after irrigation with DE.
