Abstract:
The ferti-irrigational effect of an agro-based paper mill
effluent on Abelmoschus esculentus (var. IHR-31) was investigated. Different
doses of paper mill effluent viz. 5, 10, 25, 50, 75 and 100% were used for fertigation
of A. esculentus along with bore well water (control). The study revealed
that paper mill effluent had significant (p<0.05) effect on EC, pH, OC, Na+,
K+, Ca2+, Mg2+, Fe2+, TKN, PO43¯,
SO42¯, Cd, Cr, Cu, Mn and Zn of the soil in both
seasons. Insignificant (p>0.05) changes in WHC and bulk density of the soil
were observed after irrigation with paper mill effluent. The agronomical performance
of A. esculentus was increased from 5 to 25% and decreased from 50 to
100% concentration of paper mill effluent as compared to control in both seasons.
The heavy metals concentration was increased in A. esculentus from 5
to 100% concentrations of paper mill effluent in both seasons. Biochemical components
like crude proteins, crude fiber and crude carbohydrates were found maximum
with 25% paper mill effluent in both seasons. The order of Contamination Factor
(Cf) of various heavy metals was Cr>Cd>Mn>Zn>Cu for soil and Zn>Mn>Cu>Cr>Cd
for A. esculentus plants after fertigation with paper mill effluent.
Therefore, paper mill effluent can be used as a biofertigant after appropriate
dilution to improve yield of A. esculentus.
