An experiment was carried out at the field laboratory of the Department of Agricultural Botany, Patuakhali Science and Technology University (PSTU), Patuakhali during the period from January to March, 2012 to study the effect of mugbean genotypes on growth, development, morpho-physiological, yield and yield attributing characters under the agro ecological Zone (AEZ-13) in the region of Southern part of Patuakhali District. Five hybrid genotypes of mugbean viz., Local variety (V1), BARI mung 5(V2), BINA mung 5(V3), BARI mung 6(V4) and BINA mung 8(V5) were used as planting materials for this study. Among the genotypes, BINA mung 5 showed significantly better performance  on growth, yield and morpho-physiological characters compare to other genotype during this study while local variety were less efficient among those parameters.  As a result, the tallest plant of 57.020 cm higher TDM (72.538 g/plant) and LA (421.152 cm2) were recorded in BINA mung 5 at harvest. BINA mung 5 also had higher number of seeds per pod (13.25), 1000 seeds weight (52.495g), grain yield (1.997t/ha), straw yield (3.660t/ha), biological yield (5.657t/ha) and harvest index (35.303%).  On basis of these findings, BINA mung 5 was the most productive variety under the coastal area.

An experiment was carried out at the research farm of Patuakhali Science and Technology University (PSTU) during the period from November 2010 to April 2011 to study on growth and yield performance of cowpea (BARI Falon-1 and local Falon) with different concentration of GA3 (control, 25.00, 33.33, 50.00 and 100.00 ppm) to find out the suitable variety and optimum level of  gibberelic acid (GA3) application which would be also suitable to cultivate under coastal region of Patuakhali. Among the treatments, GA3 at 33.33 ppm treated plant of BARI Falon–1 showed the better performance on growth and yield contributing characters. As a result, the tallest plant (62.53 cm), number of leaves and branches plant–1 (28.67 and 20.07, respectively), TDM (83.99 g), CGR (1.68 cm2 day-1), RGR (0.729 cm2 day-1) and NAR (1.275 cm2 day-1) were exhibited from the variety BARI Falon-1 with the spraying of GA3 at 33.33 ppm at harvest. Yield contributing characters had also higher such as pods plant–1 (11.67), length of pod (17.20 cm), seeds pod–1 (16.80), 100-seed weight (12.49 g), seed yield (20.16 g plant-1 and 3139.93 kg ha-1) and harvest index (24.04%) with the variety BARI Falon–1 whily it was treated by 33.33 ppm GA3. Hence, it can be concluded that the application of GA3 up to 33.33 ppm than other GA3 levels and BARI Falon-1 than Local Falon would be the most suitable for obtaining the greater yield of cowpea under the coastal area of Patuakhali region. So, considering the above observation, BARI Falon-1 therefore is suggested to cultivate in Patuakhali region while 33.33 ppm GA3 would be also optimum level for the better prodcution of cowpea.Progressive Agriculture 27 (2): 94-100, 2016
