Abstract/ Executive Summary:

At Ishurdi, sowing dates showed significant differences at both locations, however earlier sowings produced higher yield. All the mutant lines had shown reasonable yield at Nov. 10 sowing. The mutant line N₁M-149 produced highest seed yield (1317.3 kg ha^-1) in Nov.10 sowing followed by mutant lines/variety N₁M-134 (1139.8 kg ha^-1) and Barimasur-4 (1113.6 kg ha^-1). On the other hand, at Magura, the check variety Barimasur-4 produced the higher seed yield (1290 kg ha^-1), followed by the mutant N₁M-149 (1140.7 kg ha^-1) at Nov.10 sowing. The mutant line N₁M-134 produced the lowest yield (624 kg ha^-1) at this location for sowing time Nov. 30. Results revealed that Nov. 10 was better in seed yield in all the mutants and check variety.

Keywords: Sowing date, Yield and Lentil

Location: BINA sub-stations at Ishurdi and Magura

Start Date: 00-00-2004

End Date: 00-00-2004

Program Area: Variety and Species

Commodity: Lentil

Objectives:

The objective was to evaluate the yield performances of lentil mutants as affected by sowing dates

Methodology:

Three lentil mutant (N₁M-134, N₁M-149 and N₂M-119) with a check variety Barimasur-4 were grown under two sowing dates (Nov.10 and Nov. 30) during rabi season, 2004. Seed rate was 30 kg/ha. The locations were BINA sub-stations at Ishurdi and Magura. The experiment was laid out in randomized complete block designs (RCBD) with three replications. A unit plot size was 4m x 2m. Seeds were sown in lines with row to row spacing 30 cm. At maturity plant population and seed yield were recorded from the 3 random harvest of one linear meter / plot. Data on yield and yield attributes were recorded from randomly selected 10 plants from each plot. The data were analyzed as per design used and means compared by DMRT.

Achievement/Findings:

Three lentil mutants viz. N₁M-134, N₁M-149 and N₂M-119 and Barimasur-4 were assessed under two sowing dates( Nov. 10 and Nov.30) in two locations (Ishurdi and Magura). Early sowing (Nov.10) produced higher yield while delayed sowing decreased yield of the mutants. Mutant line N₁M-149 produced highest yield at Ishurdi and Magura on Nov.10 sowing (1317 and 1141 kg ha^-1), respectively. Among the mutants, N₁M-149 showed the highest yield potential both at Ishurdi and Magura.
