ABSTRACT
The experiment was conducted during Kharif 2 season of 2017-18 in the farmer’s field of Dolirkandi and Boisaki sites under the upazila Sariakandi and Dhunut of Bogura district. Two varieties of blackgram viz. BARI Mash-3 and Local (check) were tested in both locations. The experiments were laid out in RCB Design with three replications having plot size 1320 m2. The highest plant height was found in local cultivar than that of BARI Mash-3 in both of the locations, which is one the strong ground to achieve more yields in blackgram. The performance was best up to 35% for pod characteristics and about 47% more yields were acquired from BARI Mash-3 compared to local/cultivated variety in Dolirkandi site. On the other hand the performance was best up to 34% for pod characteristics and about 13% more yields were acquired from BARI Mash-3 compared to local/cultivated variety in Boisaki site.

Key words: Black gram, varietal performance, BARI Mash-3, local variety, yield.

Introduction

Blackgram (Vigna mungo) belongs to the family leguminosae, is one of the important pulse crops in Bangladesh. It is used in various forms such as grain for human consumption and fodder for cattle, green manure, cover crop and short-lived forage. It is a fast growing, short season, drought tolerant, (Pillai and Arasuya, 1997) and low input promising crop for south East Asia. The national average yield of black gram in Bangladesh is low. This low yield may be due to the cultivation of the low yielding local varieties, incidence of diseases and insects, lack of technical knowledge etc. BARI already developed some high yielding blackgram varieties. These varieties have potential to help generate farmers’ income in very short period of time. Great circulation of these varieties in different areas of Bangladesh is perquisite in respect of grain crop security in Bangladesh. Hence, the present study was undertaken to evaluate the performance of the BARI variety under farmer’s field condition and make popularized among the farmers to promote their adoption in char land of Bogura.

Materials and Methods

The experiment was conducted during Kharif 2 season of 2017-18 in the farmer’s field of Dolirkandi and Boisaki sites under the upazila Sariakandi and Dhunut of Bogura district. Two varieties of blackgram viz. BARI Mash-3 and Local (check) were tested in both locations. The experiments were laid out in RCB Design with three replications having plot size 1320 m2. Seeds were sown on 22nd September 2017 in Dolirkandi and 28th September 2017 in Boisaki. Soil was fertilized with NPK at the rate of 20.74, 20 and 20 kgha-1, respectively. The crop was harvested during 14th December 2017 in Dolirkandi and 20th December 2017 in Boisaki. At harvest, 10 randomly selected plants from each plot were carefully uprooted to record plant height (measured from the root-stem junction to the top of the shoot), number of pods/plant, number of seeds/pod, 1000 seed weight and seed yield. The yield per plot was recorded and converted into yield per hectare. Collected data were analyzed statistically by using MSTAT software packages and mean differences for each character were compared by Least Significant Differences (LSD) test (Gomez and Gomez. 1984).
