Modern Farming: Black Turmeric (Curcuma caesia) cultivation under soilless medium

Black turmeric commonly known as “kali Haldi”. It is an industrially important plant now categorized as endangered species. Due to the Ethnobotanical importance, it is useful for the treatment of many diseases. An experiment was conducted during, Sep.2021 to Jan.2022 at DIBER, DRDO, Haldwani, Nainital (Uttarakhand). During the study period, the maximum and minimum temperature of the field and low-cost shade net recorded was 28-34°C and 16 -18 °C, respectively. soil less cultivation system used for the growing the crop was a UV stabilized buckets white color and vertical net pot filled with mixture of coco peat and vermiculite and partite ratio (3:1:1). The aim of this study was grown Black Turmeric under soilless culture. The result found that the germination of turmeric rhizome takes place under soilless culture after 15 DAT. Nutrients solution supplied after the germination. The result shows the growth of crop after 15 days. The number of rhizomes arising from mother rhizome also positively effect on production under soilless culture. The 5-7 rhizome node growth found after one month. The maximum (20 cm) plant growth found after one month from DAT. The maximum yield (1-1.5 kg/plant) found under per pot. Whereas the minimum average yield was found (560 gm/plant) under per pot.
