Impact of integrated nutrient management on growth and flowering of gladiolus (Gladiolus grandiflorus L.) cv. American beauty

Abstract

The present investigation entitled “Impact of integrated nutrient management on growth and flowering of gladiolus (Gladiolus grandiflorus L.) cv. American Beauty” was carried out at Floriculture Research Farm, Navsari Agricultural University, Navsari (Gujarat) during the year 2015-16. The experiment was conducted in Randomized Block Design (RBD) with three replications and ten treatments consisting of bio-fertilizers (Azotobacter, PSB and KMB), different levels of inorganic fertilizers and their combinations. Among all treatments application of 100% RDF + FYM @ 7.5 t/ha + Azotobacter + PSB + KMB + 1% foliar spray of Nauroji Novel Organic Liquid Fertilizer was found most effective in plant height at 60 and 120 days (59.73 and 84.00 cm), number of leaves/plant (19.87), minimum days taken to spike initiation (48.10), days to harvesting of spike from initiation of spike (16.57 days), maximum spike length (66.63 cm), rachis length (39.53 cm), number of florets per spike (11.30), diameter of 2nd floret (8.50 cm), vase life of the spike (14.93 days), with highest production of spikes/plant (2.50).
