Assessment of biological parameters in tomato cultivars irrigated with fertilizer factory wastes

In the present evaluative study, an effort has been made to assess different biological parameters like seed germination and growth of plants, etc. in three varieties of tomato. Fertilizer factory liquid wastes contain nitrogenous and ammonical substances which showed a promotional impact on percent seed germination and growth parameters due to these nutritional supplements present in it. The incremental effects have been recorded up to the extent of lower dilutions of fertilizer wastes. Lower concentration of waste (i.e.25%) found to be growth-promoting while rest higher concentrations of fertilizer wastes showed a decrement impact on growth parameters. Growth of tomato plants such as length of root and shoot under different effluent concentrations viz. 25, 50, 75, and 100% shows significant variation over the control. The results clearly show that with the increase of dilution of effluent, percent germination and growth parameters also changes. This may be due to the accumulation of certain solid and dissolved solids in plants that have a negative correlation with growth response in tomato varieties studied.
