Abstract

Lupin (Lupinus perennis L.) is an emerging cut flower with enormous potential to be used extensively. Plant spacing plays a vital role in obtaining a better growth and development by manipulating the micro environment. Since there is a little data on impact of plant spacing on growth and flowering of Lupin, present study was carried out to standardize the spacing in order to obtain quality produce of Lupin cut flower. The experiment was laid out in Randomized Block Design (RBD) comprising of 11 treatments which replicated thrice. Results revealed that growth parameters like number of branches per plant (15.43) and number of leaves per plant (113.60) recorded maximum under treatment T5 (45 × 45 cm). Whereas, T1 (30 × 30 cm) spacing contributed maximum plant height (77.45 cm) and minimum days for flowering parameters such as days for flower bud initiation (44.21), flower stalk emergence (47.79) and 50 per cent flowering completion (24.08) however, treatment T5 (45 × 45 cm) recorded maximum duration of flowering (56.74 days), crop duration (175.39 days) and flower quality parameters viz., length of flower stalk (55.71 cm), number of florets per stalk (112.21), diameter of flower (1.35 cm) and yield parameters like number of stalks per plant (8.63), per plot (241.64) and per hectare (4.26 lakhs) while minimum under treatment T1 (30 × 30 cm) spacing.

Conclusion

On the basis of results obtained and facts mentioned in this chapter, among the different spacing levels which influenced plant growth, flowering, cut flower quality and yield of Lupin, it can be concluded that treatment T5 (45×45 cm) may be recommended for commercial cultivation of Lupin for cut flower production.
