Rajma is an important rabi pulse crop cultivated by local farmers in the plain regions of
South Tripura. Productivity remained low due to the continued cultivation of the local
variety, poor crop management practices, and limited access to quality inputs and organized
markets.

To address these constraints, the College of Agriculture, Tripura implemented a
Demonstration on Scientific Cultivation of Rajma during the Rabi season
2025–26 under the ICAR–Indian Institute of Pulses Research (ICAR-IIPR)
collaborative programme “Promotion of Pulses in NEH Region (Tripura).”
The demonstration covered 25 ha in South Tripura district involving farmers of Doulbari and
Indira Nagar villages.
Under the programme, the improved rajma variety Kashipur Farash Bean was introduced in 12 ha
of the demonstration area, replacing the traditionally grown local variety. Farmers were
supplied with quality seed, fertilizers, Trichoderma-based bio-pesticide,
micronutrients, plant protection chemicals, manual seed drills, and manual ridgers. Two
capacity-building programmes on Good Agricultural Practices (GAP) in rajma cultivation were
organized, followed by field demonstrations on line sowing, seed treatment with
Trichoderma, ridge making, and micronutrient application.
A Crop Cut Evaluation conducted on 15 March 2026 demonstrated the superiority of the improved
production technology. The Kashipur Farash Bean variety recorded 12–15% higher yield
than the local variety, with an average productivity of 1.8–2.0 t/ha. Besides higher
yield, the improved variety produced more pods per plant, larger seed size, and better grain
quality, making it more acceptable in the market.
A major achievement of the programme was the establishment of a direct market linkage between
the participating farmers and a buyers’ organization in Raipur, Chhattisgarh. Owing to
the superior seed size, attractive colour, and better grain quality, the harvested produce
fetched a premium price. The entire produce was successfully transported by rail to Raipur,
eliminating the role of intermediaries and improving farmers’ profitability. Economic
analysis indicated that farmers adopting the scientific production technology realized a
benefit–cost (B:C) ratio of 1.8–2.0:1, demonstrating the economic viability of the
intervention.
The demonstration showed that the adoption of improved varieties coupled with scientific crop
management and market linkage can significantly enhance rajma productivity, quality, and
farmers’ income in the North Eastern Hill Region. The success has generated considerable
interest among neighbouring farmers, creating opportunities for wider horizontal spread of
improved rajma cultivation in Tripura.
The institute describes the 12 ha under Kashipur Farash Bean as half of the demonstration area;
against the 25 ha it reports, that is 48%.
