Abstract
A nursery study was conducted to find out the effect of organic mixtures on stone germination and seedling growth of mango (Mangifera indica L.) cv. Totapuri under nethouse and polyhouse in the Department of Horticulture, UAS, GKVK, Bengaluru. To improve the germination and seedling quality, a nursery study was conducted to notice better combination of organic mixtures. The seedlings were kept to study the growth under nethouse and polyhouse for 180 days. Under polyhouse, the treatment (T10) consists of Soil : Sand : FYM : Vermicompost : Cocopeat : PGPR [2:1:1:1:1:1] ratio recorded maximum germination percentage (80.00 %) and better growth parameters, viz. higher plant height (55.07 cm), more number of leaves (19.45), higher vigour index of fresh and dry weight (3822.00 and 2854.60 respectively) and higher root length (41.54 cm) at 180 DAS. Similarly, under nethouse the treatment (T10) noted maximum germination percentage (70.00 %) and better growth parameters, viz. higher plant height (44.81 cm), more number of leaves (14.00), higher vigour index of fresh and dry weight (3051.60 and 2286.43 respectively) and higher root length (34.74 cm) at 180 DAS. Thus, it can be concluded that, the combination of organic mixtures are positively influenced the germination, growth and vigour of mango cv. Totapuri seedlings under polyhouse compared to nethouse.
