Assessment of the Effects of NPK on Flowering Characters of Gladiolus (Gladiolus grandiflorus L.) cv. Big Time Supreme

Abstract

Aim: Gladiolus the most important cut flower crop and as it has great demand in national and international flower market it is worthwhile to apply the experimental trial on it, in respect to estimate the flowering characters of Gladiolus. Place and duration of Study: The field experiment was conducted at Horticultural Research Farm-I, Babasaheb Bhimrao Ambedkar University (A Central University), Lucknow, (U.P), India. During the 2018-2019 and 2019-2020 rabi seasons. Results: Replicated thrice having twenty three treatments in each replication. The minimum days taken to emergence of spike (102.21 and 101.04 days), The maximum number of spikes per plant (1.29 and 1.30), The minimum days to first floret opening (109.25 and 110.25 days), The maximum duration of flowering (15.55 and 15.85 days), The highest length of spike (87.35 and 88.05 cm), The highest number of florets per spike (15.12 and 16.13), The maximum diameter of floret (9.25 and 9.42 cm) and The maximum length of floret (9.85 and 9.92 cm) with the application of N 20g + P 15g + K 15g (T16). Moreover, the treatment T16 showed the best results on flowering characters of gladiolus. Appeared as the best practice for better flowering and therefore it may be recommended to boost up flower production and quality of gladiolus.
