Abstract/ Executive Summary:

On-Farm performance of six Barley lines/varieties namely K163, BHL01, BHL02, BHL03, BB3 and BB4 were evaluated at Paikgacha MLT site, Khulna and Kalapara, Patuakhali during the rabi season 2003-04. The line BHL02 produced the significantly highest grain yield among the lines at Khulna but BB4 showed the highest at Patuakhali.

Keywords: Barley, salinity

Location: Satkhira and Patuakhali

Start Date: 01-11-2003

End Date: 05-03-2004

Program Area: Risk Management in Agriculture

Commodity: Barley

Objectives:

To find out the performance of this variety/lines at farmers field of saline area.

Methodology:

The trial was conducted at Paikgacha MLT site and Kalapara, Patuakhali during Rabi season, 2003-2004 with six Barley lines/varieties namely K163, BHL01, BHL02, BHL03, BB3 and BB4 following RCB design with three replications in farmers field. The unit plot size was 1m 1m. The crop was sown on 27 November 2003 at Khulna and 13 December at Patuakhali. Line to line spacing was 30cm. Fertilizer were applied at the rate of 100-60-40 kg/ha of N, P2O5, and K2O respectively. All Urea, TSP and MP were applied as basal. Irrigation was given at initial growth stage at Khulna but no irrigation at Patuakhali. All the intercultural operations were done as and when necessary. The crop was first harvested during the first week of March 2004 at Khulna and 5 April 2004 at Patuakhali. Data on yield and yield attributes were collected and analyzed statistically. The soil salinity level at Khulna during 26 November, 11 and 26 December 2003, 10 and 25 January 2004, 10 and 26 February 2004, 10 and 25 March 2004 were 2.14, 1.04, 1.80, 3.96, 5.16, 6.82, 4.90, 6.14 and 3.35 mm hos/cm, respectively whereas salinity level at Patuakhali were 2.65, 3.24, 3.68, 5.06, 5.87, 7.56, 8.22, 8.76 and 9.55 mm hos/cm on 1 & 30 December 2003, 15 & 30 January, 15 February, 1, 16 & 30 March 2004, respectively.

Achievement/Findings:

MLT site, Paikgacha Spike/m2, 1000-grain weight and grain yields were significantly influenced by variety/line. Performance of Barley lines/varieties have been presented in Table 1. The results revealed that the significantly highest grain yield (2120kg/ha) was obtained from BHL02. The lowest yield (1567kg/ha) was obtained from K163 but statistically identical for BHL4 and BB4. The highest yield produced by BHL–02 could be due to maximum spike/m2 and longest spike. The lowest yield produced by K-163 could be due to minimum number of grain/spike. MLT site, Kalapara, Patuakhali Plant height, grains/spike, effective tiller/hill and grain yields were significantly influenced by variety/genotypes. The line BB3 and BB4 showed similar in height and higher than other lines. Spike length was not significantly influenced by the line. Significantly the highest grains/spike was recorded from line BB3. But effective tiller/hill was higher from BHL1 & BHL3. Significantly the highest grain yield was obtained from line BB4. The line BB3, BHL2 and BHL1 showed similar yield but lower yield than BB4.
