For the 2025 cropping season, ARDC Bajo has initiated a series of rice research trials activities aimed at promoting sustainable rice cultivation, improving varietal performance, and ensuring quality seed production in line with 13FYP
- Alternate Wetting and Drying (AWD) Technology
A field experiment comparing AWD with continuous flooding has been established to assess water-saving potential and crop performance. The technique uses perforated field tubes to manage irrigation based on soil moisture levels, targeting improved water-use efficiency without compromising yield. - Premium and Traditional Rice Variety Characterization
Ten premium rice varieties are being evaluated on-station for morphological and agronomic traits. An additional ten traditional varieties have been requested from the National Biodiversity Centre (NBC) for characterization in the coming season to support conservation and future varietal development. - K-Booster Nutrient Application Trial
In collaboration with the National Soil Services Centre (NSSC), this trial evaluates the impact of K-Booster—a natural potassium-based product—on rice growth and yield. The study aims to assess its role as a sustainable alternative to chemical fertilizers in Bhutanese rice farming systems. - Use of Effective Microorganisms (EM) and Organic Fertilizer
Also coordinated with NSSC, this trial assesses the efficacy of EM and farmyard manure (FYM) on soil health and rice productivity, providing insight into low-input, organic fertilization options for local conditions. - Demonstration of Released Rice Varieties
Seven released rice varieties have been transplanted as part of an on-station demonstration to showcase their performance and promote adoption among farmers and stakeholders. - Breeder Seed Production
Breeder seed production is being carried out for six rice varieties to ensure availability of quality foundation seeds for further multiplication and distribution. - Seed Purification of Khamtey Rice
A seed purification program for the traditional Khamtey rice variety is underway to maintain varietal purity and support conservation of this high-value local rice.
These integrated research and demonstration activities reflect the Centre’s commitment to enhancing rice productivity, conserving traditional varieties, and promoting climate-smart and organic practices in Bhutan.
