Morphological Variation and Yield Performance of Photo-insensitive Lablab bean [Lablab purpureus (L.) Sweet] Genotypes under Sylhet Region
Journal Title: Asian Research Journal of Agriculture - Year 2017, Vol 7, Issue 4
Abstract
An experiment was conducted during August 2013 to February 2014 at the experimental field of the Sylhet Agricultural University (SAU), Sylhet to study the morphological variability, yield and yield contributing characteristics among the five lablab bean genotypes viz., SB003, BP003, IPSA Sheem-2, SB008 and SB010. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The genotypes SB003, IPSA Sheem-2 and SB008 had reddish brown seed coat color while it was black in SB010 and reddish color in the genotype BP003. Among the genotypes 100 dry seed weight was ranged from 35.50 g (IPSA Sheem-2) to 41.30 g (SB003). Variation in yield and yield contributing characteristics were found among five lablab bean genotypes. The genotype SB010 produced the maximum number of pods plant-1 (562.3) followed by SB008 (381.3). A similar trend was also noticed in pod yield plant-1 among the genotypes. The highest pod yield was recorded in the genotype SB010 (20.46 ton ha-1) while it was the lowest in IPSA Sheem-2 (6.26 ton ha-1). For seed production potentiality, the genotype SB010 produced the highest amount of seed plant-1 (451.67 g) since it produced the maximum number of dry pods plant-1 (228.67). Seed yield ha-1 varied from 1.0 ton to 3.0 tons. However, pod and seed yield ha-1 indicating bright scope to popularize lablab bean production in the Sylhet region.
