 ABSTRACT

The present investigation was carried out at Floriculture and Landscaping Block, College of Horticulture, VCSG, UUHF, Bharsar, Pauri Garhwal during March-September, 2016. The experiment consists of eight treatments viz. control, PSB (2 ml/l), Azotobacter (25 g/l), VAM (20 g/l), PSB (2 ml/l) + Azotobacter  (25 g/l), PSB (2 ml/l) +VAM  (20 g/l), Azotobacter (25 g/l) +VAM (20 g/l) and PSB (2 ml/l) + Azotobacter (25 g/l) +VAM  (20 g/l). The treatments were replicated thrice in a Randomized Complete Block Design. The results revealed that the minimum days taken to first floret opening (111.76± 0.26), maximum diameter of 2nd floret (12.46 ±0.11cm), number of spikes per plant and plot (2.00 ± 0.11 and 32.00 ±2.13, respectively) and number of corms per plot (31.00 ±1.15) were recorded from the plants grown in plots applied with PSB (2 ml/l) + Azotobacter (25 g/l) +VAM (20 g/l). However, maximum corm weight (60.60 ± 1.11g), corm diameter (6.20 ± 0.10 cm), number of cormels per plant and plot (37.33 ± 1.20 and 600.76 ±1.94, respectively) were recorded in treatment combination Azotobacter (25 g/l) +VAM (20 g/l).

Key words: Azotobacter, Corm yield, Floral attributes, Gladiolus, PSB and VAM.
