Abstract/ Executive Summary:

An experiment was conducted to find out the effect of soil moisture regimes on growth and grain yield of barley at the experimental field laboratory of Department of Crop Physiology and Ecology, Hajee Mohammad Danesh Science and Technology University, Dinajpur to study the performance of two barley varieties namely, BARI Barley 5 and BARI Barley 6 during the rabi season of 2006-2007. Four levels of irrigations were applied, viz., control or no irrigation (I0), one irrigation at the tillering stage, when only 30 mm water was applied (I1), two irrigations, one at the tillering and one at the booting stages, 60 mm water was applied during these two stages (I2) and three irrigations, one at the tillering, one at the booting and one at the grain filling stages, 90 mm water was applied during these three stages (I 3). Three irrigations produced the highest TDM, CGR, LAI, and NAR while, LAR was the highest in rainfed crops (I0). In irrigated crops, the highest grain yield (3.40 t ha-1) was produced by three irrigations applied at 25, 45 and 65 DAS (I3) followed by two irrigations (3.22 t ha-1). The lowest grain yield (1.96 t ha-1) was recorded in the non-irrigated (I0) barley varieties. Between two barley varieties, BARI Barley 5 produced significantly higher grain yield (3.11 t ha-1) than BARI Barley 6 (2.87 t ha-1).

Start Date: 00-00-2006

End Date: 00-00-2007

Program Area: Crop-Soil-Water Management

Commodity: Barley, Water management

Objectives:

Tillering, booting and heading are adversely affected by water stress at the early growth stage and dry matter partition, leaf area indices, crop growth rate also affected with water deficit condition (Baheri et al. 2005 and Rafiq et al. 2005). The present study was set up to find out a suitable irrigation level for better growth and yield of barley under field condition.

Methodology:

The experiment was conducted at the Crop Physiology and Ecology Field Laboratory, Hajee Mohammad Danesh Science and Technology University, Dinajpur, during the period from November, 2006 to April, 2007. Seeds of two barley varieties were collected from BARI, Gazipur. These are BARI Barley 5 (Hulled) and BARI Barley 6 (Hull-less). Seeds were sown continuously by hand in 25 cm apart rows. The seed to seed distance was 4 cm. The experiment was laid out in a split-split plot design with 3 replications. The irrigations were assigned in the main plots and the barley variety was assigned in the sub-plots. The unit plot size was 2.5 m X 2 m having a plot to plot distance of o.5 m. Barley was sown in November 16, 2006. Four levels of irrigations were applied, viz., control or no irrigation (I0), one irrigation at the tillering stage, 30 mm water was applied in total lifespan (I1), two irrigations, one at the tillering and one at the booting stages, 60 mm water was applied in total lifespan (I2) and three irrigations, one at the tillering, one at the booting and one at the grain filling stages, 90 mm water was applied in total lifespan (I3) were given. Growth analysis has been established followed by standard techniques for the study of plant growth and development.

Achievement/Findings:

In the present study, among different irrigation treatments, the three times irrigations (13) where 90 mm water was applied at 25, 45 and 65 DAS, exhibited /treated/ as a suitable water management technique for the cultivation of barley during rabi season. Between the two varieties, BARI Barley 5 showed better performance in their growth and yield attributes.
