Abstract/ Executive Summary:

A study was conducted to investigate the phenology and growth of barley in relation to sowing date and irrigation frequency. Results revealed that earlier sowing with higher irrigation took longer duration to attain all the phenological stages viz., tillering, booting, heading, anthesis and maturity. While late sowing with no irrigation required the minimum time to attain all of the phenological stages of barley. The growth parameters performed better with earlier sowing and higher irrigation frequency. The highest value of LAI, TDM, CGR, RGR and NAR was recorded in November 1 sowing with three irrigations. Whereas, late sowing with no irrigation gave the lowest value for all the growth parameters.

Keywords: Sowing date, Irrigation frequency, Phenology, Growth

Location: Crop Botany Research Field and Laboratory, Hajee Mohammad Danesh Science and Technology University,Dinajpur

Start Date: 00-11-2005

End Date: 00-03-2006

Program Area: Crop-Soil-Water Management

Commodity: Barley

Objectives:

1. To know the effect of sowing date and irrigation levels on phenological, morphological and growth parameters of barley.

Methodology:

The experiment was conducted at the Crop Botany Research Field and Laboratory, Hajee Mohammad Danesh Science and Technology University, Dinajpur during the period of November, 2005 to March 2006. The experiment was two factors randomized complete block design (RCBD) with three replications. Four sowing date viz., November 1 (S₁), November 15 (S₂), November 30 (S₃), December 15 (S₄) and four irrigation levels viz., no irrigation (IR₀) one irrigation (IR₁) at the tillering stage, two irrigations (IR₂) one at the tillering and one at the booting stage, three irrigations (IR3) one at the tillering, one at the booting and one at the grain filling stage were the two factors. Unit plot size was 2.5 m x 2.5m. The land was uniformly fertilized with 100-86-30-22-3 kgha^-1 of N-P-K-S-Zn in the form of urea, TSP, MP, Gypsum and Zinc sulfate respectively; in addition 10 ton cow dung ha^-1 was applied in each experimental unit. The seeds of barley were sown in rows 30 cm apart at about 3 cm depth from the soil surface and the seed rate was 120 kg ha^-1. BARI 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 3 cm water was applied in each irrigation. Data were collected on some phenological characteristics like days to tillering, booting, heading, anthesis and maturity. Number of days from sowing to tillering of 50% tillers, emergence of 50% heads, booting of 50% of plant and anthesis of 50% of the ears in each plot were estimated manually. Number of days from sowing to maturity was determined visually by the total loss of green color from the plant. Five randomly selected plants from middle rows of each plot were collected for measuring some morphophysiological and growth parameters were undertaken from 20 DAS at 10 days interval and continued to physiological maturity. Then the plants were separated into leaves, stems and roots and corresponding dry weights recorded after being oven dried at 80 ± 2⁰C for 72 hours. The leaf area of each sample was measured by on digital leaf area meter (Model: CI 202, USA). Leaf area index (LAI), crop growth rate (CGR), relative growth rate (RGR), net assimilation rate (NAR) and total dry matter (TDM) were then calculated.

Achievement/Findings:

From the overall results it might be concluded that earlier sowing with higher irrigation took longer duration to attain almost all the phenological stages. Similarly the growth parameters performed better with earlier sowing and higher irrigation frequency. The highest value of LAI, TDM, CGR, RGR and NAR was recorded in November 1 sowing with three irrigations.
