title: Ferti-irrigational effect of paper mill effluent on agronomical characteristics of Abelmoschus esculentus L. (Okra).
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 ofA. 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, PO4(3-), SO4(2-), 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.
