Irrigational Impact of Sugar Industry Effluent on Vegetative Characters of Lycopersicon esculentum Mill. Var. Navodaya

Five concentration of sugar industry effluent was given in irrigation medium i.e., 20% as T1, 40% as T2, 60% as T3, 80% as T4 and 100% as T5. The vegetative characters studied were height of the plant, length of petiole, length of lamina, breadth of lamina, length of stomatal aperture, breadth of stomatal aperture and number of stomata per unit area. Height of the plant was found to increase with the treatment of sugar industry effluent and maximum increase was recorded as 6.62 per cent inT3 treatment. Maximum increase in the length of petiole was noted in T2 treatment and it was 21.12 per cent. Length and breadth of lamina was found to increase with treatment of sugar industry effluent and maximum increase were noted in T3 treatment and it was 20.86 and 19.19 per cent respectively. Length of stomatal aperture was almost unaffected with the treatment of sugar industry effluent; a little increase was recorded in T1 and T3 treatment and it was 0.09 per cent and 2.23 per cent respectively. While the treatment T2, T4 and T5 showed a little decrease in the length of stomatal aperture and it was 2.39, 0.23 and 1.1 per cent respectively over the control. Breadth of stomatal aperture also found to be unaffected by the treatment of different concentration of sugar industry effluent. A little increase was recorded in T2, T3 and T4 treatment as 2.87 per cent, 4.62 per cent and 1.17 per cent respectively. A little decrease was also recorded in T1 and T5 treatments and it was 2.25, and 4.89 percent respectively. Number of stomata per unit area was also found to increase with the irrigation of different concentration of sugar industry effluent and maximum increase was 20.89 per cent in T3 treatment. It was observed that T3 treatment where plant were irrigated with 60 per cent concentration of sugar industry effluent was found to enhance the maximum vegetative growth in almost all the parameters taken into consideration except length of petiole. It is concluded that the concentration upto 60 per cent favour the vegetative growth of Lycopersicon esculentum Mill. Var Navodaya. The concentration above 60 per cent showed toxic effect on the vegetative growth of tomato plants.
