The investigation on organic ginger (var. gorubathan) was carried out to study the effect of organic, inorganic manure and biofertilizers on ginger with reference to rhizome yield and its attributes. The study revealed that, ginger showed better response to the application of organic, inorganic and bio-fertilizer. An experiment was carried out at Horticultural Research Station, Mondouri, BCKV, West Bengal to identify the suitable bio-organic combination for production of with three types of biofertilizers namely nitrogenous biofertilizer (Azotobacter chroococcum), phosphate solubilizing Bacteria (Bacillus polymixa) and potassic mobilizer (Fraturia aurantea) with combination of inorganic fertilizer doses (B1= NPK (100%) + Azotobacter + PSB + K Mobilize B2= NPK (75%) + Azotobacter + PSB + K Mobilizer B3= NPK (50%) + Azotobacter + PSB + K Mobilizer and B4= Recommended NPK (100%) and two levels of FYM . 15 t and 30 t. Among different treatments, the sole effect farmyard manure, the maximum number of primary fingers (), weight of primary finger ( g), length of primary finger ( cm), breadth of primary fingers ( cm), number of secondary fingers (), weight of secondary finger ( g), length of secondary finger ( cm), breadth of primary fingers ( cm), yield ( t ha-1 ) and the higher oleoresin () content was recorded with 30 t ha-1 , in case of inorganic and biofertilizer, maximum number of primary fingers (), weight of primary fingers (), length of primary fingers ( cm), length of secondary finger ( cm), breadth of secondary finger ( cm), yield ( ha-1 ) and oleoresin () content was observed with combination of B1 (NPK 100% + Azotobacter + PSB + K mobilizer). | Yield and quality of ginger as influenced by biofertilizers, organic and inorganic manures
