The objective was to evaluate three yard long bean genotypes (BARI yard long bean-1, BARI yard long bean-2 and Kagornatki) in three planting dates (20 March, 20 April and 20 May) under acidic soil conditions of Sylhet. The two factors field experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Yard long bean planted on 20 March recorded the minimum number of days to flower (40.33), the minimum number of days to first harvest (53.33), the maximum number of pods per plant (31.01), the highest individual pod weight (12.25 g), pod length (45.98 cm), per plant pod yield (389.47 g) as well as per decimal pod yield (97.34 kg). The genotype BARI yard long bean-1 was the earliest in flowering (41.66 days). BARI yard long bean-1 had the highest number of pods Original Research Article
