Abstract/ Executive Summary:

A field experiment was conducted at PRC, Ishurdi and PRSS, Gazipur during rabi season of 2016-2017 to find out the effect of phosphorus with moisture level on yield and BOAA content of lathyrus. There were two moisture levels like- control and light irrigation at 20 DAE which were placed in the main-plot and 5 ‘P’ levels (kg/ha) viz. Control, 10, 20, 30 and 40 were placed in the sub-plot. The experiment was laid out in a slit-plot design with 3 replications. Moisture levels had no significant differences on seed yield but little higher seed yield was found in light irrigation at 20 DAE for both the locations. Different P levels had no significant effect on grain yield but numerically the highest seed yield was obtained by 20 kg/ha of P level for both the locations. The combined effect of moisture level and P level had no significant variation seed yield. The highest gross margin was recorded from light irrigation at 20 DAE with 20 kg/ha P level at Gazipur but without irrigation@ 20 kg/ha P level produced the highest at Ishurdi and lowest was in control for both the locations.But the highest BCR was obtained by without irrigation with10 kg/ha P level for both the locations and the lowest was produced by light irrigation at 20 DAE with 40 kg/ha P level.

Start Date: 00-00-2016

End Date: 00-00-2017

Program Area: Postharvest and Agro-processing

Commodity: Soil fertility, Lentil

Objectives:

To find out the effect of “P” fertilizer with moisture level yield and BOAA content in lathyrus.

Methodology:

The field experiment was conducted at PRC, Ishurdi and PRSS, Gazipur during rabi season of 2016-2017 to find out the effect of phosphorus with moisture level on yield and BOAA content of lathyrus. There were two moisture levels like- control and Light irrigation at 20 DAE which were placed in the main-plot and and 5‘P’ levels (kg/ha) viz. Control, 10, 20, 30 and 40 were levels were placed in the sub-plot. The experiment was laid out in a slit-plot design with 3 replications. The unit plot size was 3m x 4m. Soils were collected before sowing and after harvesting for NPK analysis. The sowing date was 19 November, 20016 for both the locations. Fertilizers N and K @ 20-20 kg/ha and P as per treatment were used as basal. The variety was used Serajganj local and seed rate was 60 kg/ha. Irrigation @ 2-3cmwas done as per treatment by surface irrigation. During sowing, moisture level (0-15 cm) was 22% but at the time of irrigation it was 17%. Intercultural operations were done as and when required. The crop was harvested on 21 March, 2017 and 29 March, 2017 at Joydebpur and Ishurdi, respectively. Data on yield contributing characters were recorded from 10 randomly selected plants from each plot and seed yield (kg/ha) was recorded from whole plot at harvest. The recorded data were statistically analyzed. Besides these, seed samples of Lathyrus as per treatment have been collected for BOAA analysis which is under process. Later on it will be done through the cooperation of ICARDA. Economic analysis results are presented. The highest net return was recorded from light irrigation at 20 DAE with 20 kg/ha P levelat Gazipur but without irrigation@ 20 kg/ha P level produced the highest at Ishurdi and lowest in control. But the highest BCR was obtained by without irrigation with10 kg/ha P level for both the locations and the lowest was produced by light irrigation at 20 DAE with 40 kg/ha P level.

Achievement/Findings:

From the last two years study, it is revealed that P @ 20 kg/ha is effective for achieving higher seed yield of lathyrus. But it will be finalized after receiving the analytical results of BOAA content.
