Effect of growth and yield of the ginger with the combination of organic, inorganic and biofertilizers

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 F2 (30t ha-1), maximum number of tiller (16.96) under F2 (30t ha-1), Plants under F2 (30t ha-1) recorded maximum leaf number (156.0) and maximum plot yield (9.92 kg 3m-2) were observed with F2 (30t ha-1). In case of inorganic fertilizer and biofertilizer, the maximum plant height of (85.60 cm) recorded under B1 (NPK 100% + Azotobacter + PSB + K mobilizer) maximum number of tiller (16.04) was observed under B1 (NPK 100% + Azotobacter + PSB + K mobilizer), maximum leaf number (157.50) were associated with B1 (NPK 100% + Azotobacter + PSB + K mobilizer) maximum yield 10.57 kg 3m-2 was observed with B1 (NPK 100% + Azotobacter + PSB + K mobilizer).
