Abstract/ Executive Summary:

The experiment was conducted at Pulses Research Centre, Ishurdi, Pabna, during rabi season 2018-19 to find out the suitable germplasm/s having higher yield of grasspea under relay condition using a randomized complete block design with three replications. Significant genotypic differences were detected for all recorded traits. The entry BGP 130010 flowered earlier than others and the entry BKX 0002-4 was matured earlier followed by BGP 130010 and Narail local. The highest yield was obtained from BGP 130010 (1692 kg/ha) followed by Narail local and BGP 13008. Three genotypes BGP 130010, Narail local and BGP 13008 was selected for next breeding trial.

Program Area: Crop-Soil-Water Management

Commodity: Grasspea

Objectives:

To evaluate the performance of grasspea germplasm under relay condition.

Methodology:

The experiment was consisted of seven genotypes along with BARI Khesari-2 as check and carried out in rabi, 2018-19 at Pulses Research Centre, Ishurdi, Pabna. The study was undertaken to evaluate the performance and growth of grasspea under relay condition. The experiment was laid out in a RCB design with three replications and spacing was 50 cm between rows. The unit plot size was 6 rows and 4 m long with 1 m border between plots and 1 m between replications. Seeds were sown on 30 October, 2018 in between T. aman rice rows carefully in the transplanted monsoon rice field after drainage of excess water, before 15 days of rice harvest. Seeds were sown in between the T. aman rice rows carefully on wet soil 15 days prior to rice harvest. For this experiment, short duration aman rice field (BINA Dhan 7) was used. Rice was harvested with 20 cm remaining straw at the field. Rice straw was quickly removed from the field to save the lentil seedlings. Recommended fertilizers were used for relay before seed sowing. Mulching was done and soil crusts were broken after rice harvesting. Each of the entries were investigated from seedling to harvest and compared with checks. Ten plants from each unit plot were selected at random outside the harvest area and tagged at the maturity of the crop for the data collection on yield contributing characters. The crop was harvested when 80% of the plant and pod turned to straw color. Yield data was recorded from the whole plot and converted into kg/ha. The recorded data were compiled and tabulated for statistical analysis. Analysis of variance was done using the R software. Yield and yield contributing characters are presented.
