Influence of Bioinoculants on Dormancy and Growth of Gladiolus (Gladiolus grandiflorus L cv. Black Jack) Seed Corms

摘要

A field experiment was conducted to study the influence of bio-inoculants such as panchagavya and manchurian mushroom tea on dormancy and growth of gladiolus corms. The corms treated with panchagavya and manchurian mushroom tea at 2 per cent gave better sprouting and growth parameters viz. speed of sprouting (0.75 quotient), sprouting percentage (50.33 and 94.33 percent respectively at 15 and 30 days after planting), less time for sprouting (16 and,30 days respectively for 50 arid 100 percent sprouting), vigour index (1375), plant height (36.6,47.3 and 59.5 cm respectively at 30, 60 and 90 days after sprouting), less time for spike emergence (61 days), 50 and 100 per cent flowering (71 and 82 days respectively), number of spikes/ m2 (14.67) and corm diameter (18.37 cm). Corm yield parameters were not shown significant differences among treatments except for corm diameter. Use of recommended dose of fertilizers (100:50:50 kg NPK/ha/year) was inferior to all other treatments.
