Effect of bio-fertilizer on flowering, and corm parameters of Gladiolus cv. American beauty

Abstract

An experiment was undertaken to explore the effect on flowering and corm parameters of the biofertilizer in gladiolus (Gladiolus grandiflorus L.) cv. and laid out in Randomized Block Architecture (RBD) experiment with Azotobacter, Phosphobacteria, Azospirllium (Azotobacter + Phosphobacteria), respectively, (Azospirillum + Phosphobacteria). Results showed that minimum days taken to spike initiation (48.67 days), maximum diameter of 2nd floret (9.14 cm), number of florets per spike (10.86), number of spikes per plant (2.90), number of spikes per hectare (398065.70), number of corms per plant (2.59), weight of corms per plant (74.00 g), weight of cormels per plant (11.92 g), size of corm (5.86 cm), nitrogen (1.84 percentages per plant) Bio-fertilizer was identified in this experiment, in order to increase soil fertility and crop production in sustainable agriculture.
