Production Technology for In Vitro Induced Micro-rhizomes of Ginger in High-Tech Poly-house

Abstract

The production technology for the commercial cultivation of ginger using in vitro produced (tissue culture generated) and hardened micro-rhizomes, under the high-tech greenhouse conditions is detailed. From two season's experiments, it was found that yield realized with the fertigation schedule of 75:50:50 kg NPK/ ha has yielded the highest yield of 700 g fresh rhizome per plant. Yield was best in the planting done with single bud rhizome (650 g) compared to the microrhizome (630 g) and conventional rhizome with 20 g size (575 g). Among the varieties, Athira, Karthika and Aswathy, experimented, Karthika gave the highest yield of 651 g/ plant.

It was also found from the experiments that there is no yield advantage in ginger with higher amount of seed material. Potting mixture with 1:1:1 ratio of sand, soil and cow-dung will be best.
