Abstract
The present investigation entitled, "Standardization of NPK for spider lily (Hymenocallis speciosa L.) under hill zone of Kamataka," was conducted at the College of Horticulture, Department of Floriculture and Landscape Architecture, Mudigere, Keladi Shivappa Nayaka University of Agricultural and Horticultural Sciences, Shivamogga, during the year 2020-21. The experiment was laid out in a Randomized Block Design, with nine
treatments (viz., T1 - Control, T2 - 50:15:25 kg NPK/ha, T3 - 50:20:25 kg NPK/ha, T4- 75:15:25
kg NPK/ha, Ts - 75:20:25 kg NPK/ha, T6- 50:15:50 kg NPK/ha, T1 - 50:20:50 kg NPK/ha, Ts - 75:15:50 kg NPK/ha and T9 -75:20:50 kg NPK/ha) and three replications. The results revealed that significant differences were observed among different treatments of NPK doses. The treatment comprising of 75:20:50 kg NPK/ha recorded the maximum plant height (96.40 cm), leaf length (99.63 cm), leaf breadth (6.97 cm), leaf area (458.67 cm2), chlorophyll a, band total chlorophyll content of the leaves (2.93, 2.98 and 5.91 mg/g fresh weight, respectively), number of suckers (5.80), spike length (81.66 cm), flower bud length (21.40 cm), flower bud diameter (1.27 cm), flower bud weight (3.59 g), flowering duration (32.20 days), flower bud yield per plant (185.79 g), flower bud yield per plot (3.33 kg), bud yield per hectare (9.73 t), number of flowers per spike (21.31), number of spikes per plant (5.03), number of spikes per hectare (90.54), vase life with and without anthers (2.96 and 3.34 days, respectively), shelf life (37.79 hrs.), number of bulbs and bulblets per plant (5.87 and 5.83, respectively), diameter of bulbs and bulblets (13.98 cm and 5.87 cm, respectively), weight of bulb (997.46 g), bulb and bulblet yield (94.63 and 6.48 kg, respectively), B:C ratio for loose flowers and bulb yield (5.23) and cut spike (3.23), available N, P and K (250.80, 13.83 and 156.48 kg/ha, respectively), m1mmum days taken for spike emergence (25.00) and days taken for bud initiation to harvesting of flower spike (9.41). Hence, the above treatment may be recommended for commercial cultivation of spider lily under hill zone of Kamataka.
