Abstract:
A field experiment was conducted at the research farm of Sher-e-Bangla
Agricultural University, Dhaka-1207, from March to July, 2014 to evaluate
promising cultivars of okra. Sixteen okra cultivars viz. Shaymol Bangla,
Sarosh-3, BARI Dherosh-1, Porosh Plus, OK-285, Deb-412, Parvani Kranti,
Kalatia, Green soft, Arka Anamika, Malvika, Green valley, Toa DK-2,
Shehzadi, Gunjon, Kochi were used as treatments. The experiment was laid
out in a Randomized Complete Block Design (RCBD) with three
replications. Screening was done based on morphological features, yield and
yield contributing features and physiological features. Leaves per plant were
the maximum for Parvani kranti at harvest. Anthesis occurred in OK-285
prior to any other varieties. Minimum incidence of YVMV was found from
the variety Sharosh-3. In all other morphological attributes viz. plant height,
days required for 80% germination, pods plant-1 and pod yield as well as
physiological attributes like net assimilation rate, intercellular CO2
concentration, respiration rate and stomatal conductance were the highest for
variety Green valley. The highest pod yield (14.26 t/ha) was obtained from
the variety Green valley which was closely followed by Porosh plus (10.22
t/ha) and the lowest yield was obtained from the variety Parvani kranti (5.23
t/ha). So, Green Valley was the best variety in respect of morphological and
physiological characteristics among the studied varieties.
