Efficacy of arbuscular microbial inoculations in relation to organic growing media on growth and budtake of citrus nursery were investigated in the current study. Three soil solarized organic growing media Soil,Soil + Farmyard manure and Soil + Vermicompost enriched with bioinoculants Glomus mossae, Gigaspora and Acaulospora, consortium of Arbuscular Mycorrhizal fungi (AMF) and uninoculated was kept as control.The combinational effect of soil + vermicompost enriched with consortium of AMF recorded the maximumseedling height (68 cm), diameter (6.81 mm), number of leaves (94.23) and plant biomass (58.82%). The rootgrowth attributes exhibited maximum length and diameter of tap root (45.88 cm and 7.12 mm respectively) andnumber of secondary roots (50.02). Total microbial count was also recorded maximum with soil + vermicompostsupplemented with consortium of AMF. Kinnow budded on rough lemon rootstock attained maximum buddingsuccess (88.73 %) with combinational application of soil + vermicompost fortified with Consortium of AMF.The same combination furthermore registered maximum length (20.04 cm) and diameter (8.73 mm) of sprout,number of leaves (14.61), leaf area (17.00 sq cm), N, P and K content in leaves and roots of Kinnow budlings.The highest N, P and K (1.51, 0.16 and 1.05 % respectively) in roots of budded plants was recorded in soil +vermicompost with consortium of AMF inoculation. The present study established the positive role of organicgrowing media and potent isolates of AMF on seedling growth and nutrient and bud take of rough lemonseedlings. Soil + vermicompost combined with consortium of AMF was found to be the most promising forraising quality nursery and maximum bud take of Kinnow on rough lemon.
