Lupin (Lupinus perennis L.) is an emerging cut flower with enormous potential to be used extensively. Plant spacing plays a vital role in obtaining better growth and development by manipulating the microenvironment. Since there is little data on the impact of plant spacing on the growth and flowering of Lupin, the present study was carried out to standardize the spacing in order to obtain quality produce of Lupin cut flowers.
The experiment was laid out in Randomized Block Design (RBD) comprising 11 treatments which were replicated thrice. Results revealed that growth parameters like the number of branches per plant (15.43) and the number of leaves per plant (113.60) recorded maximum under treatment T 5 (45 × 45 cm).
Whereas, T 1 (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 percent flowering completion (24.08)however, treatment T 5 (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), the 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 T 1 (30 × 30 cm) spacing.
