Trans-geographical introduction of cluster bean (Cyamopsis tetragonoloba L.) in organic regime of Sikkim Himalaya - conditions conducive for successful cultivation

The present study was conducted to explore the possibility of cultivation of cluster bean in non-traditional areas under the organic regime of Sikkim Himalaya. The cluster bean cv. Pusa Navbahar was planted on eight different dates under four organic nutrient combinations. Results revealed that the sowing time and organic manures showed significant differences in morphobiochemical traits of cluster bean. The crop sown during the first three dates i.e fourth week of April, the second week of May, and the fourth week of May did not germinate. The sowing on the second week of August with FYM 50% (5 t/ha) + Vermicompost 50% (2.5 t/ha) was the most appropriate combination for the better growth, yield, and biochemical traits of cluster bean in Sikkim, suggesting the possibility for expansion of cluster bean in non-traditional areas. The introduction of cluster bean in Sikkim may help in diversifying the agricultural sector and provide additional income to the farmers.
