Abstract

Calcium plays an important role in plant growth and in many physiological activities of bulbous flowers. It has been found to be the best for enhancing both vegetative and flowering attributes in bulbous flower crops. With this background, an experiment was conducted at the experimental block (under naturally ventilated polyhouse) of the Department of Floriculture and Landscape Architecture, College of Horticulture, Mudigere, under Keladi Shivappa Nayaka University of Agricultural and Horticultural Sciences, Iruvakki, Shivamogga during 2022-2023. The experiment was laid out in Randomized Complete Block Design consisting of thirteen treatments- viz., T1 - control, T2 - 30 g/m2 calcium ammonium nitrate, T3 - 40 g/m2 calcium ammonium nitrate, T4 - 50 g/m2 calcium ammonium nitrate, T5 - 30 g/m2 calcium nitrate, T6 - 40 g/m2 calcium nitrate, T7 - 50 g/m2 calcium nitrate, T8 - 100 g/m2 calcium oxide, T9 - 200 g/m2 calcium oxide, T10 - 300 g/m2 calcium oxide, T11 - 20 g/m2 dolomite, T12 - 30 g/m2 dolomite and T13 - 40 g/m2 dolomite with three replications. Among different treatments, the application of dolomite at 40 g/m2had taken minimum days for flower bud initiation (29.80), first floret opening (54.53), 50 per cent flowering (61.33), maximum duration of flowering (17.33 days), number of buds per spike (3.60), bud length (8.53 cm), bud diameter (21.64 mm), petal length (11.37 cm), petal breadth (4.37 cm), length of the flower stalk (71.85 cm) and vase life of flowers with and without anthers (8.17 and 9.55 days, respectively).While, minimum was recorded in control. Hence, it is concluded that the soil application of dolomite 40 g/m2 at the time of planting proved to be promising for enhancing the flowering and quality of Asiatic lily.

Conclusion

On the basis of the result obtained in the present investigation it is concluded that, the soil application of 40 g per m2 dolomite at the time of planting proved significant for improving the flowering and quality of Asiatic lily under protected cultivation. Hence, the treatment 40 g/m2 dolomite may be recommended for commercial cultivation of Asiatic lily.
