Evaluation of cashew nut (Anacardium occidentale L.) germplasm in North-Eastern Hilly region of Bangladesh

Five cashew nut germplasms (AO Jai-001, AO Jai-002, AO Jai-003, AO Jai-004 and AO Jai-005) were evaluated in an experiment carried out in 2024–2025 at the Citrus Research Station, BARI, Jaintaapur, Sylhet. The experiment was conducted in a Randomized Complete Block Design with three replications. Significant variations among germplasm were noted for all the attributes evaluated. Among five cashew nut germplasm AO Jai-001 exhibited superior vegetative growth with the tallest height, highest base girth and widest spreading. Flowering was early in AO Jai-003 and maturity durations (42.67 days), potentially offering early harvest advantages. AO Jai-001 produces maximum nut yield per plant (3.52 kg), edible kernel weight per plant (1.09kg). However, based on overall growth and yield performance, AO Jai-001 and AO Jai-003 were identified as promising germplasm for cultivation in the north-eastern hilly region of Bangladesh.
