Abstract/ Executive Summary:

An experiment was conducted from March 2014 to August 2014 at the experimental field of Sylhet Agricultural University (SAU), Sylhet to study the morphological variability, yield, and yield contributing characteristics among the four lablab bean genotypes viz., SB003, SB010-1, SB011, and BP003. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The genotypes SB003 and SB010-1 had reddish-brown seed coat color while it was black in SB011 and reddish color in the genotype BP003. Among the genotypes, 100 dry seed weights were ranged from 34.00 g (SB010-1) to 42.00 g (SB011). Variation in yield and yield contributing characteristics were found among four lablab bean genotypes. The genotype SB003 produced the maximum number of pods plant^-1 (206.3) followed by SB010-1 (134.3) while it was minimum for the genotype SB011 (92.67). A similar trend was also noticed in the case of pod yield plant^-1 among the genotypes. The highest pod yield was recorded in the genotype SB010 (7.73 ton ha^-1) while it was the lowest in SB011 (2.87 ton ha^-1). However, pod yield ha^-1 indicates bright scope to popularize lablab bean production during early Kharif in the Sylhet region.

Start Date: 00-03-2014

End Date: 00-08-2014

Program Area: Variety and Species

Commodity: Lablab bean

Objectives:

To assess the morphological variability and yield performances among the collected genotypes of Lablab Bean.

Methodology:

The experimental plot was located at the Horticulture research field of Sylhet Agricultural University, Sylhet and the experimental period was March 2014 to August 2014. Four lablab bean genotypes were used in the experiment. The seeds of these genotypes were collected from the Department of Horticulture, Sylhet Agricultural University, Sylhet. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The unit plot size was 1.5 m × 6.0 m accommodating a single row per bed. Pits were spaced 1.0 m in a bed and 2.0 m between two adjacent beds. The experimental plots were prepared by digging pits about two weeks before sowing. The land was fertilized with cowdung, urea, TSP, and MoP ® 10 ton, 50 kg, 150 kg, and 150 kg ha^-1, respectively. A full dose of cowdung, TSP, and half of the MoP was applied during pit preparation two weeks before transplanting. The remaining MoP and urea were applied in three equal installments as top dressing at 15, 30, and 45 days after transplanting. Hence the land was acidic in nature, lime (Dolomite) was applied in the field @ 4 kg decimal^-1. The soil of the pits and basal dose of fertilizers mixed well and prepared in such a way that the pit tops remained at least 10 cm above the ground level to facilitate drainage. For planting two seeds of the five genotypes were sown in polybags containing a well-prepared soil mixture on 5 March 2014. Then10 day old seedlings were transplanted in the pit and out of two seedlings; one was thinned out two weeks after transplanting the young growing plant was supported by a single bamboo stake in each pit. Weeding and irrigation were done whenever necessary. The experiment was protected from herbivorous animals (e.g. cows, sheep, goats, etc.). Fencing was made around the experimental plots for this purpose. The pods were also protected from aphids, jute hairy caterpillar (Spilosoma obliqua), and pod borer (Maruca vitrata) invasion by applying Maladan @ 2 ml L^-1 of water. Data were recorded from all experimental plants on different morphological parameters, yield, and yield attributes and were analyzed using MSTAT software for the interpretation of results.

Achievement/Findings:

Among the genotypes, the genotypes SB003 and SB010-1 showed better performance especially in respect of pod yield. Therefore, these genotypes can be taken under consideration for commercial cultivation in the early Kharif season in the Sylhet region.
