Abstract:
An experiment was carried out at Horticultural Research Station, Mondouri, BCKV, West Bengal to identify the suitable bio-organic combination for production of organic ginger variety Gorubathan, with three types of biofertilizers namely nitrogenous biofertilizer, phosphate solubilizing Bacteria and potassic mobilizer with combination of inorganic fertilizer doses (100%, 75% and 50% NPK) and two levels of FYM
i.e. 15 t and 30 t. Among different treatments, maximum plant height, number of tillers, number of leaves and plot yield 3m
-2 were recorded, in respect of sole effect of farmyard manure the maximum plant height (83.81) under F
2 (30t ha
-1), maximum number of tiller (16.96) under F
2 (30t ha
-1), Plants under F
2 (30t ha
-1) recorded maximum leaf number (156.0) and maximum plot yield (9.92 kg
3m
-2) were observed with F
2 (30t ha
-1). In case of inorganic fertilizer and biofertilizer, the maximum plant height of (85.60 cm) recorded under B
1 (NPK 100% +
Azotobacter + PSB + K mobilizer) maximum number of tiller (16.04) was observed under B
1 (NPK 100% +
Azotobacter + PSB + K mobilizer), maximum leaf number (157.50) were associated with B
1 (NPK 100% +
Azotobacter + PSB + K mobilizer) maximum yield 10.57 kg
3m
-2 was observed with B
1 (NPK 100% +
Azotobacter + PSB + K mobilizer).
