Abstract/ Executive Summary:

An adaptive experiment was implemented at RARS, Rahmatpur, Barishal during Rabi season of 2018-19 to evaluate the adaptive quality of eight selected cowpea germplasms with one check variety in southern agro-climatic conditions. Eight selected cowpea germplasms viz.CPL-1-17, CPL-2-17, CPL-3-17, CPL-3-17, CPL-4-17, CPL-5-17, CPL-6-17, CPL-7-17, CPL-8-17 including one check variety BARI Felon 1 were evaluated in the trial. Results showed that all the characters under this study were significantly different among the genotypes except days to maturity, number of seeds/pod and hundred seed weight. Germplasm. The germplasm CPL-8-17 had produced the maximums seed yield (1569.4 kg/ha) which was statistically identical with CPL-7-17 (1297.2 kg/ha) whereas the lowest seed yield can be observed from the check BARI Felon 1and CPL-6-17 (630 kg/ha and 693.6 kg/ha respectively).

Start Date: 00-00-2018

End Date: 00-00-2019

Program Area: Crop-Soil-Water Management

Commodity: Cowpea

Objectives:

To evaluate advance cowpea germplasms to make a suggestion for cowpea varietal improvement in southern agro-climatic conditions.

Methodology:

The experiment was conducted at the experimental field of Regional Agricultural Research Station (RARS), Rahmatpur, Barishal in the rabi season, 2018-19 to evaluate the performance of eight selected cowpes germplasms with the check variety BARI Felon 1. Eight selected cowpea germplasms viz.CPL-1-17, CPL-2-17, CPL-3-17, CPL-3-17, CPL-4-17, CPL-5-17, CPL-6-17, CPL-7-17, CPL-8-17 including one check variety BARI Felon 1 were evaluated in the trial. The experiment was laid out in Randomized Complete Block Design with three replications. The unit plot was 10 rows and 4m long with spacing 50cm×5cm. Seeds were sown in the rows on 18th November 2018. Intercultural operations e.g. Irrigation, weeding etc. were done in time. Data on yield contributing characters were recorded from 10 randomly selected plants from each plot. Grain yield (kg/ha) was recorded from the whole plot. Data were analyzed statistically by using R software at 5% level of significance.

Achievement/Findings:

With findings of the present study it could be concluded that, the germplasm CPL-8-17 had produced the maximums seed yield (1569.4 kg/ha) which was statistically identical with CPL-7-17 (1297.2 kg/ha). So, these germplasms should be considered for further trial to release a variety.
