Abstract:
The present investigation was carried out to study the “Effect of biofertilizers and growing media on seed germination and seedling vigour of tamarind (Tamarindus indica L.)” at College of Horticulture, Dr. Y.S.R. Horticultural University, Venkataramannagudem, West Godavari District in the year 2021-22. The experiment was laid out in a factorial randomized block design (FRBD) with three replications containing of sixteen treatment combinations which consists of two factors viz., biofertilizers at four levels (B₀: control, B₁: Azospirillum, B₂: PSB and B₃: KRB) and growing media at four levels (M₁: soil, M₂: soil + cocopeat @ 2:1, M₃: soil + vermicompost @ 2:1, and M₄: soil + cocopeat + vermicompost. @ 2:1:1). The treatment combination T₁₄ recorded highest in germination parameters like days required for initiation of germination (8.50), maximum germination percentage (99.79) and in growth parameters like height of the seedling(28.75, 50.99, 66.72, and 89.61 cm respectively), number of leaves(11.36, 23.81, 36.22 and 59.42 respectively), stem diameter(1.23, 3.89, 5.36 and 7.26 mm respectively), root length (15.63, 28.41, 37.87 and 44.10 respectively) at 30, 60, 90 and 120 DAS and survival percentage (99.53) at 120 DAS.
