Abstract/ Executive Summary:

An experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University, Bangladesh during November 2011 to March 2012 to study the growth and yield of wheat to irrigation stages. Four irrigation stages viz. I₀: No irrigation; I₁: Irrigation at crown root initiation (CRI) stage (18 DAS); I₂: Irrigation at pre-flowering stage (45 DAS) and I³: Irrigation at both CRI and pre-flowering stage were used following Randomized Complete Block Design with three replications. Maximum number of tiller/hill (5.2), CGR (6.7 gm^-2day^-1), RGR (0.03 gg^-1day^-1), dry matter content (28.7%), number of spikes/hill (4.5), number of spikelets/spike (19.0), ear length (17.5), filled grains/spike (30.8), total grains/spike (32.9), weight of 1000-grains (47.1 g), grain yield (3.9 tha^-1), straw yield (4.9 tha^-1), biological yield (8.8 tha^-1) and harvest index (45.9%) were found from I3 whereas minimum from I0. On the other hand, early flowering (70.6 days), maturity (107.2 days) and minimum number of unfilled grains/spike (2.1) were also found from I₃.

Location: Experimental field of Sher-e-Bangla Agricultural University, Dhaka

Start Date: 00-11-2011

End Date: 00-03-2012

Program Area: Crop-Soil-Water Management

Commodity: Wheat

Objectives:

To study the growth and yield of wheat to irrigation stages

Methodology:

The experiment was conducted at experimental field of Sher-e-Bangla Agricultural University, Bangladesh during the period from November 2011 to March 2012 to study the growth and yield of wheat as influenced by irrigation stages. Experiment consisted four different irrigation stages viz. I₀: No irrigation i.e., control condition; I₁: Irrigation at crown root initiation (CRI) stage (18 DAS); I₂: Irrigation at pre-flowering stage (45 DAS) and I₃: Irrigation at both CRI and pre-flowering stage following Randomized Complete Block Design with three replications. BARI Gom-21 (Shatabdi) was used. Seeds were sown with maintaining 20 cm line to line distance and plant to plant 5 cm. Cowdung, Urea, TSP, MP, Gypsum were applied @ 10 t ha-1, 200 kg ha^-1, 80 kg ha^-1, 50 kg ha^-1 and 120 kg ha^-1 respectively as basal dose (BARI, 2006). Data were collected on plant height, number of tiller/hill, dry matter content/plant, crop growth rate, relative growth rate, days to flowering, days to maturity, number of spike/hill, ear length, number of filled grains/spike, number of unfilled grain/spike, number of total grain/spike, weight of 1000-grains, grain yield/ha, straw yield/ha, biological yield and harvest index. Using the data on dry matter the following growth parameters were derived . Collected data were analyzed statistically using MSTAT-C computer package program. The mean values of all the characters were calculated and analysis of variance was performed. The significance of the difference among the treatment means was estimated by the Duncan Multiple Range Test (DMRT) at 5% level of probability.
