Abstract/ Executive Summary:

The experiment was conducted at Joydebpur, Ishurdi and Barind, Rajshahi to observe performance of barley genotypes under rainfed condition during the rabi season 2003-2004. The trial consisting eight genotypes including one check variety BARI Barley 3. Among the genotypes BHL–02 was produced the highest yield (2.15 t/ha) at Joydebpur while BHL–08 (2.55 t/ha) and BHL-05 (2.09 t/ha) produced the highest yield at Ishurdi and Rajshahi respectively.

Keywords: Barley, Screening, Rainfed

Location: Joydebpur, Ishurdi and Rajshahi under BARI

Start Date: 00-00-2003

End Date: 00-00-2004

Program Area: Variety and Species

Commodity: Barley

Objectives:

To evaluate the performance of some selected barley lines in rainfed condition.

Methodology:

This experiment was conducted with 8 entries including BARI Barley-3 as check variety at 3 locations i.e., Joydebpur, Ishurdi and Rajshahi Barind area during 2003-04 following Randomized complete block design with three replications. The unit plot size was 2.0m x 1.5m maintaining spacing of 25cm between rows. Fertilizers were applied at the rate of 100:60:40 kg/ha of N, P₂O5, K₂O, respectively. Half of N and the whole amount of other fertilizer were applied as basal dose and rest of the urea was applied in two installments. Intercultural operations were done as and when necessary. Data on days to 50% heading and maturity, plant height, number of fertile tillers per plant, spike length, 1000 grain weight, grain yield per plant and yield per hectare were recorded. Soil moisture data and weather data were recorded accordingly and presented in Appendix-1. Statistical analysis was also done following DMRT

Achievement/Findings:

From the study, it was observed that among the genotypes BHL– 02 was earliest entry for days to heading (53 days) and it was also the highest yielder (2.15 t/ha) followed by the entry BHL-04 (1.90 t/ha) at Joydebpur. It was observed that BHL-02 was the earliest entry (57 days) for days to heading and BHL–08 produced highest yield (2.55 t/ha) followed by BHL-07 (2.07 t/ha) and BHL-09 (2.06 t/ha) at Ishurdi. BHL-05 was the highest yielder (2.09 t/ha) at Rajshahi Barind area. From the combine effect of the genotypes over 3 locations it was observed that BHL-08 was the best performer in terms of spike length (8.26 cm) and grain yield (1.79 t/ha) which was identical to the genotypes BHL-07 (1.67 t/ha), BHL-02 (1.64 t/ha), BHL-04 (1.60 t/ha) and BHL-09 (1.58 t/ha) for grain yield.
