Abstract/ Executive Summary:

A field experiment was conducted at PRC, Ishurdi and RARS, Jessore during rabi season of 2014-2015 to find out the effect of sowing date on the growth and yield in varying moisture, temperature and day length. There were three sowing dates i.e. early sowing (25 October, 2014), Optimum sowing (10 November, 2014) and late sowing (25 November, 2014). It was laid out in a RCB design with three replications there was a significant effect of dates of sowing on branches/plant, pods/plant and seed yield at PRC, Ishurdi but all the parameters were sinificant at RARS, Jessore. The 2^nd date of sowing (10 November) produced the highest seed yield of 2990 kg/ha at PRC,Ishurdi and 1883 kg/ha at RARS, Jessore as well as high yield contributing characters which influenced to achieveing higher yield. The lowest seed yield of 2220 kg/ha at PRC,Ishurdi and 1350 kg/ha at RARS, Jessore under late sowing condition due to less yield contributing characters for both the locations.

Start Date: 00-00-2014

End Date: 00-00-2015

Program Area: Crop-Soil-Water Management

Commodity: Lentil

Objectives:

To find out the effect of sowing date on the growth and yield in varying moisture, temperature and day length.

Methodology:

A field experiment was conducted at PRC, Ishurdi and RARS, Jessore during rabi season of 2014-2015 to find out the effect of sowing date on the growth and yield in varying moisture, temperature and day length. There were three sowing dates i.e. early sowing (25 October/2014), Optimum sowing (10 November/2014) and late sowing (25 November/2014). It was laid out in a RCB design with three replications. Plot size was 6m x 3m.The variety BARI Masur- 6 was used and seed rate was 35 kg/ha. In the experimental plots, fertilizers @14-20-20-10 kg NPKS/ha was applied during final land preparation. Intercultural operations were done as and when required. Data on different growth parameters and soil related were collected as required for the APSIM model. 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 and presented

Achievement/Findings:

From the last two years study, it may be concluded that around 10 November is the optimum time for sowing lentil to achieving higher seed yield. But after modeling the range of sowing dates for achieving higher yields will be identified.
