Abstract/ Executive Summary:

The experiment was conducted at Crop Physiology and Ecology research field and laboratory, Hajee Mohammad Danesh Science and Technology University, Dinajpur, during the period of November, 2005 to March, 2006 to study the yield attributes and yield of barley (Hordeum vulgare L.) in relation to different sowing dates and irrigation levels. BARI barley 5 was sown with four sowing dates viz., November 1 (SI), November 15 (S2), November 30 (S3) and December 15 (S4), and four irrigations viz., Control (IR0), one irrigation at the tillering stage (IR1), two irrigations one at the tillering stage and one at the booting stage (IR2), and three irrigations, one at the tillering stage, one at the booting stage and one at the grain filling stage (IR3). Most of the yield components i.e., plant height, fertile tiller, spike length, fertile spikelets, 1000-grain weight, grain yield (3.61 t/ha) and HI were found the highest in the plants sown in November 1 with three irrigations and the lowest plant height, fertile tiller, spike length, fertile spikelets, 1000-grain weight, grain yield (1.66 t/ha) and HI were obtained in the crop sown in December 15 with no irrigation (control) while infertile tillers and infertile spikelets showed a reverse result with delay in sowing and control irrigation. It has found that November I sowing with three irrigations showed the best performance in respect of growth, yield attributes and yield (3.61 t/ha) of barley.

Start Date: 00-11-2005

End Date: 00-03-2006

Program Area: Crop-Soil-Water Management

Commodity: Barley

Objectives:

To find out the effect of different sowing dates and irrigation levels on yield and yield attributes of barley.

Methodology:

The experiment was conducted at the Crop Physiology and Ecology research field and laboratory, Hajee Mohammad Danesh Science and Technology University, Dinajpur, during the period of November 2005 to March 2006 at 25°38' N latitude and 88°41 longitude and at the elevation of 34.5m above the sea level. The experiment was two factorial randomized complete block design (RCBD) with three replications. The two factors were adopted as: (A) four seeding dates viz., S I: November 1. S2: November 15, S3: November 30 and S4: December 15, and (B) four irrigation levels viz., IRO: no irrigation, IRI: one irrigation at the tillering stage and IR2: two irrigations one at the tillering stage and one at the booting stage and IR3: three irrigations, one at the tillering stage, one at the booting stage and one at the grain filling stage. There were a total of 48 plots having the size of 2.5 m x 2.5m each. The distance between block to block was I meter and plot to plot was 0.75 m. The land was uniformly fertilized with 100-86-30-22-3 kg for the supplement of N-P-K-S-Zn ha^-1 in the form of urea, TSP. MP. Gypsum and Zinc sulfate respectively. In addition, cowdung at the rate of 10 ton ha^-1 was appl ied in each experimental unit. The seeds of barley were hand sown in rows at about 3 cm depth from the soil surface with the seed rate of 120 kg ha^-1. The variety BARl barley 5 was used as planting material in the present study. Irrigation water was applied as per experimental treatment stated earlier. A measured amount of water was applied with a bucket. An equal amount of 6 cm water was applied in each irrigation. At maturity, ten plants were selected randomly and data were recorded for plant height, fertile tillers per plant, infertile tillers per plant, spike length. number or spikelets per spike, fertile spikelets per spike, infertile spikelets per spike, thousand-grain weight and harvest index. Grain yield was recorded on whole plot harvest basis and calculated as ton per hectare. The collected data were analyzed statistically using the analysis of variance (ANOVA) technique with the help of computer by MSTAT-C program. The treatment means were compared by Duncan's New Multiple Range Test.

Achievement/Findings:

The overall results indicated that the early sowing (November I) performed better in relation to growth. yield attributes and yield of barley. Three irrigations at early tillering, booting and grain filling stages seemed to be suitable for the same. In conclusion, the early sowing (November I) with three irrigations (IR3) performed the best for improving the yield of barley. However, further investigations are essential to reach at firm conclusion.
