Abstract

Lupine (Lupinus perennis L.) cut flower is a very versatile cut flower with a lot of potential for usage. Since very little study has been done on the “Influence of nitrogen fixing biofertilizers on growth, flowering, quality and yield of Lupine at graded levels of nitrogen”, a study was carried out to obtain quality produce of Lupine cut flower. The experiment was laid out in Randomized Complete Block Design (RCBD) with 8 treatments and 3 replications. As the recommended dose of nitrogen is high, nitrogen is reduced up to 25 % and incorporated with biofertilizers which not only improved the flower quality and yield but also reduced the use of inorganic nitrogen which may affect the soil. The results revealed that growth parameters like plant height (59.36 cm), number of branches per plant (19.44) and number of leaves per plant (87.67) recorded maximum in treatment T7 (100% Recommended dose of nitrogen (75 kg/ha) + P (25 kg/ha) + K (45kg/ha) + Rhizobium + Azotobacter (625ml/ha))Whereas, flowering parameters such as minimum days taken for flower bud initiation (46.67), flower stalk emergence (49.60), 50 per cent flowering (22.20) and duration of flowering (164.52 days), whereas flower quality parameters like stalk length (69.51 cm), number of florets per stalk (135.20), diameter of flower (1.57 cm) and yield parameters like number of stalks per plant (6.25), per plot (224.88) and per hectare (4.63 lakhs) in treatment T8 (75 % Recommended dose of nitrogen (75 kg/ha) + P (25 kg/ha) + K (45 kg/ha) + Rhizobium + Azotobacter). Hence treatment T8 can be recommended.

Lupine, Biofertilizers, Cut flower, flower quality, flower yield and stalk length

Conclusion

Based on results obtained and facts mentioned in this chapter, among the different treatments T7(100 % RDN + Rhizobium + Azotobacter + P + K) influenced morphological parameters whereas T8 (75 % RDN + Rhizobium + Azotobacter + P + K) influenced flowering, cut flower quality and yield of Lupine, hence, it can be concluded that treatment T8 may be recommended for commercial cultivation of Lupine for cut flower production as it saves 25 % of nitrogen.
