Effect of Growing Media, Structures and Sowing Dates on Seed Germination and Seedling Growth of Custard Apple cv. 'Balanagar'

The treatment of soil : vermicompost : paddy husk (1:2:1) had significant influence by recording maximum seed germination at 30 DAS, seedling length, number of leaves per seedling, number of primary ischolar_mains per seedling, length of tap ischolar_main per seedling, number of secondary ischolar_mains per seedling at 30, 60 and 90 days after sowing. It also recorded the maximum fresh and dry weight of seedling at 90 DAS. The condition of net house with 70 per cent mesh size recorded maximum seed germination at 30 DAS, seedling length, number of leaves per seedling at 30 and 90 DAS, number of primary ischolar_mains per seedling at 30, 60 and 90 DAS, length of tap ischolar_main per seedling at 30 and 60 DAS, maximum seedling girth at 30 and 60 DAS as well as maximum fresh and dry weight of seedling at 90 DAS. The sowing of seeds on 15^th April, 2012 gave maximum germination at 30 DAS and recorded maximum seedling length, number of leaves per seedling, number of primary ischolar_mains per seedling, length of tap ischolar_main per seedling, number of secondary ischolar_mains per seedling and maximum seedlings girth at 30, 60 and 90 DAS. At 90 DAS, maximum fresh and dry weight of seedling was obtained with sowing on 15^th April, 2012.
