摘要：An experiment was conducted to evaluate the effect of tannery waste on growth and flower yield of Chrysanthemum plants. The planting media were prepared by mixing garden soil, sand and tannery waste in the ratio of 3:3:1, 3:3:2, 3:3:3, 3:3:4 and 3:3:5. The pots were planted with Chrysanthemum @ 1 cuttings/pot. In control pots, sand and soil were used as planting media mixed in the ratio of 1:1. The growth and yield data obtained showed that there was a significant (p<0.01) increase in the number (88%) and weight (59%) of flowers in Chrysanthemum plants planted in pots having planting medium in the ratio of 3:3:2. Maximum increase in plant height, shoot dry weight, root dry weight and number of branches were recorded in Chrysanthemum cuttings grown in planting medium having ratio of 3:3:1. However, there was a decrease in growth and yield of plants when they were planted in media containing garden soil: sand: tannery waste in the ratio of 3:3:3, 3:3:4 and 3:3:5. The present study clearly showed that tannery waste at lower concentration promotes vegetative growth and yield of Chrysanthemum cuttings and behaves as growth inhibitor at higher concentration. Therefore, tannery waste can be successfully utilized in planting medium for production of Chrysanthemum flowers. There is also a need to screen the effect of tannery waste based planting medium on other non edible floricultural crops.
