Type: article
Abstract: Lupine is a showy hardy annual and biennial flowering plant.They are mainly grown for cut flowers and food sources.In crop performance, yield and quality result from genotypic expression, modulated by continuous interaction with the environment and other plant behavior factors.Among them, nutrients are the essential factor.The present study was formulated with different doses of nitrogen, phosphorus and potassium along with a control to standardize the optimum dose of NPK to improve the quality and quantity of Lupine.An investigation was carried out at the College of Horticulture, Mudigere, 2020-21.The experiment consisted of different levels of nitrogen, phosphorus and potassium kg/ha (T 1 -85:21:43, T 2 -50:20:40, T 3 -50:25:40, T 4 -75:20:40, T 5 75:25:40, T 6 -50:20:45, T 7 -50:25:45, T 8 -75:20:45, T 9 -75:25:45 and T 10 -Control).The results reveal that fertilizer treatments had a significant response on all parameters.The minimum days taken for first visible flower bud formation (46.07), days taken for flower stalk emergence (48.20), days required for blooming from Days After Sowing (DAS) (51.07), days taken for 50 percent flowering (25.40), the maximum duration of flowering (58.03 days), days taken for wilting from Days After Flowering (DAF) (5.01), number of florets per stalk (131.80),diameter of flower (2.22 cm), stalk length (71.56 cm), vase life (4.85days), cut flower yield per plant (5.50 stalks), per plot (192.50 stalks), per hectare (4.07 lakh) and highest BC ratio 5.95 were recorded by application of 75:25:45 kg NPK per ha which was found better over the check (85:21:43 kg NPK/ha).It can be concluded from the present investigation that nitrogen, phosphorus, and potassium play a significant role in the morphological characteristics of lupine.Hence, NPK at the rate of 85:21:43 kg per ha can be recommended for commercial cultivation of lupine under the hill zone of Karnataka.
