Abstract

This experiment was conducted in the experimental field of Department of Horticulture, Sylhet Agricultural University (SAU), Bangladesh during 2022. 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 (27.81) as well as pod yield (309.85 kg) per plant. Although individual pod weight and pod length of BARI yard long bean-1 and Kagornatki were statistically similar, the per decimal pod yield (76.86 kg) of BARI yard long bean-1 was significantly higher than Kagornatki (56.31 kg). Interaction effect showed that the genotype BARI yard long bean-1 planted on 20 March showed the best performance in terms of pod yield per plant (506.56 g) and per decimal (127.22 kg). Therefore, the genotype BARI yard long bean-1 can be recommended to cultivate at 20 March sowing date under acidic soil condition of Sylhet.

Keywords: Yard long bean, acidic soil condition, pod yield, Sylhet region
