Abstract
Pot experiments were conducted to find out the nursery management techniques in hippe (Mahua indica) at Biofuel Information and Demonstration Centre (BIDC), Hanumanamatti, University of Agriculture Sciences, Dharwad during kharif - 2015 and were laid out in RCBD.
Among different nursery mixtures, composition of red soil + white sand + vermicompost in 1:1:1 proportion (T8) recorded significantly higher values of normal seedlings (74.25 %) and germination (90.25 %) with significantly minimum abnormal seedlings (4.00 %), dead seeds (5.75 %) and hard seeds (16.00 %). This treatment also recorded significantly maximum root length of 16.70 cm, shoot length of 16.54 cm, seedling length of 33.23 cm, highest seedling dry weight of 15.31 g/10 seedlings, seedling vigour indices-I value of 2997, seedling vigour indices-II value of 1381 and also significantly highest germination rate index (2.41) was recorded at 45 days after sowing compare to other treatments.
Among different pre-sowing treatments, seeds dipping in conc. H2SO4 for 1 min (T6) recorded significantly higher values of normal seedlings (80.00 %) and germination (84.00 %) with significantly minimum dead seeds (5.80 %) and hard seeds (4.00 %). This treatment also recorded significantly maximum root length of 16.78 cm, shoot length of 16.16 cm, seedling length of 32.93 cm, highest seedling dry weight of 16.19 g/10 seedlings, seedling vigour indices-I value of 2772, seedling vigour indices-II value of 1357 and also significantly highest germination rate index (3.39) while significantly minimum abnormal seedlings (6.00 %) observed by control at 45 days after sowing compare to other treatments.
