hello sir
Ginger requires tropical,subtropical and humid climate for its commercial production.It can be successfully grown to an altitude of 1500mt.
Ginger prefers good soil, rich in humus, light, loose, friable, well drained and of at least 30 cm depth. Rhizome growth is better on slightly acidic soil.
A seed rate of 15-20 Quintal per hectare is considered to be optimum for planting. Before planting bits should be treated with fungicide like carbendazim and mancozeb by dissolving the 30 gm of powder in 15 litres of water as a safeguard against soft rot and to induce early sprouting.The spacing for planting of the ginger should be kept 25-45 cm between rows and 15-20 cm between plants.
Well rotten FYM or compost at the rate of 25-30 ton/hectare should be applied at the time of planting. The amount of inorganic fertilizer depend upon the fertility of the soil and organic manure used. It ranges between 100-120 kg nitrogen, 75-80 kg of phosphorus and 100 -120 kg of Murat of potash.
