Abstract/ Executive Summary:

Significance differences were shown in plant height, branch/plant, pods/plant, seeds/pod, seed weight and straw yield except seed yield through applying different seed rates (15 kg/ha, 20 kg/ha, 25 kg/ha and 30 kg/ha). The mutant lines/varieties (N1M-149 and E4M-934) had shown reasonable highest yield at the highest plant density (30 kg/ha), but the mutant line N5M-573 and N4M-423 (1186.7 and 1058.3 kg/ha) which gave the highest yield at 20 kg/ha. The experiment confirmed that, number of pods/plant was the main factor to give the higher yield of these mutant lines/variety

Keywords: Different date, yield and Mungbean

Location: BINA sub-stations at Ishurdi

Start Date: 10-11-2007

End Date: 15-02-2008

Program Area: Variety and Species

Commodity: Lentil

Objectives:

The objective was to observe how the yield performances of these lines were affected by seed rate

Methodology:

Four lentil mutants, N1M-149, N5M-573, N4M-423 and E4M-934 along with check variety Barimasur-4 were grown under four plant density (15 kg/ha, 20 kg/ha, 25 kg/ha and 30 kg/ha) during 2007. The locations were BINA sub-stations at Ishurdi and Magura. The experiment was laid out in Split plot designs with three replications. Seed rates were placed in the main plots and the mutant lines in the sub plot. Seeds were sown in lines with row to row spacing 30 cm. At maturity, plant population and seed yield were recorded from 3 random harvest of one linear meter plot. Data on yield attributes were recorded from randomly selected 10 plants from each plot. The data were analyzed as per design used and means were compared by LSD tests.

Achievement/Findings:

The Lentil mutant lines/varieties N1M-149 and E4M-934 had shown reasonable highest yield at the highest seed rate (30 kg/ha) but the mutant lines N5M-573 and N4M-423 gave the highest yield at 20 kg/ha (1058.3 kg/ha).
