Abstract

The dried tobacco waste was mixed in proportions of 1%, 2% and 3% in soil and filled in earthen pots of 6 kg capacity. Three replicate pots for each soil concentration were used. Tomato saplings of cultivar Bezosheetal were transplanted age of 20 days (signifying stage before flowering), 25 days (signifying stage at the start of flowering) and 45 day (signifying just at the onset of fruiting). The morphological parameters like plant height, number of leaf, flower plant(-1), number of fruits and yield plant(-1) were recorded. Nutrient parameters like moisture, total soluble solids (TSS), acidity vitamin C, reducing sugar proteins, pectin and lycopene were analyzed in tomato fruits. Experiments revealed that the yield of tomato fruit and critical nutritional parameters showed significant increase. For higher yield (183 g plant(-1)) of tomato, the best option is the use of 3% tobacco waste after 45 days of transplant. Alternatively, use of 2% tobacco waste with 45 days of transplant provides a higher quality tomato. The yield obtained here would be significantly higher than control but not as high as with 3% tobacco waste.
