Abstract/ Executive Summary:

A field experiment was conducted at PRC, Ishurdi and PRSS, BARI, Gazipur during rabi season of 2015-16 to find out the sowing method with optimum seed rate for short duration lentil lines for better crop growth and yield. There were two sowing methods- line sowing 20 cm apart and broadcast, and four seed rates like-50 kg/ha, 60 kg/ha, 70 kg/ha and 80 kg/h. It was laid out in a split-plot design with three replications where sowing methods were placed in the main-plot and seed rates were placed in the sub-plot. It was observed that between line and broadcast sowing there was no significant difference but a slightly higher yield was obtained by line sowing for both the locations. Among the seed rates, 70 kg/ha produced the highest significant seed yield and the lowest was obtained by 50 kg/ha for both the locations. The combined effect of the sowing method under different seed rates had no significant differences but numerically the highest seed yield was obtained by line sowing with 70 kg/ha seed rate for both locations.

Commodity: Lentil

Objectives:

To find out the optimum seed rate under different sowing method for short duration lentil for better crop growth and yield.

Methodology:

A field experiment was conducted at PRC, Ishurdi and PRSS, Gazipur during rabi season of 2015-2016 to find out the suitable sowing method with optimum seed rate for short duration lentil lines for better crop growth and yield. There were two sowing methods- line sowing 20 cm apart and broadcast and four seed rates eg. 50 kg/ha, 60 kg/ha, 70 kg/ha and 80 kg/h. It was laid out in a split-plot design with three replications where sowing methods were placed in the main-plot and seed rates were placed in the sub-plot. Plot size was 3m x 2m. The genotype BLX-05008-15 was used and seed rates and sowing methods were used as per treatment. In the experimental plots, fertilizers @14-20-20-10 kg NPKS/ha were applied during final land preparation. The sowing date was 9 November, 2015 for Gazipur and 16 November, 2015 for Ishurdi. Intercultural operations were done as and when required. The crop was harvested on 4 February, 2016 (88 DAS) and 18 February 2016 (93 DAS) at Gazipur and Ishurdi, respectively. During harvest data on yield contributing characters were recorded from 10 randomly selected plants from each plot and grain yield was recorded from 2.0 m²/plots and converted into kg/ha. The recorded data were statistically analyzed and mean separation was done following LSD test.

Achievement/Findings:

It was observed that between line and broadcast sowing there was no significant difference but a slightly higher yield was obtained by line sowing for both the locations. Among the seed rates, 70 kg/ha produced the highest significant seed yield and the lowest was obtained by 50 kg/ha for both the locations. The combined effect of the sowing method with seed rate had no significant differences but numerically the highest seed yield was obtained byline sowing with 70 kg/ha seed rate for both locations. It may be due to optimum plant population as the well cumulative influence of yield contributing characters which influenced to achieving higher yield. It was revealed that line sowing under 70 kg/ha seed rate is suitable for short-duration lentil genotype/lines. These were first-year experiments, so the concrete decision, should be repeated for the next season.
