Abstract/ Executive Summary:

Keywords:

Location: Agronomy Field, Sher-e-Bangla Agricultural University (SAU), Dhaka-1207

Start Date: 18-11-2012

End Date: 30-03-2013

Program Area: Crop-Soil-Water Management

Commodity: Wheat, Irrigation scheduling

Objectives:

To determine the effect of irrigation and optimum sowing time on the growth and yield performance of wheat.

Methodology:

The experiment was conducted in the Agronomy Field, Sher-e-Bangla Agricultural University (SAU), Dhaka-1207 during the period of November 18, 2012 to March 30, 2013.The experimental field was located at 23⁰41´ N latitude and 90^o 22´ E longitude at a height of 8.6m above the sea level belonging to the Agro- ecological Zone “AEZ-28” of Madhupur Tract (BBS, 2011). The soil of the research field was slightly acidic having p^H 5.8 in reaction with low organic matter content (0.78%). The experimental field was situated under sub- tropical climate; usually the rainfall is heavy during kharif season, (April to September) and scanty in rabi season (October to March). The experiment was consisted of two factors as irrigation and sowing dates. Factor A: I₀ = No irrigation and I = Irrigation (three irrigation were applied; the first irrigation was after 20 days of sowing at crown root initiation (CRI), the second after 45 days and the third irrigation after 62 days). Factor B: S₁ = 1^st sowing on 18 November, 2012, S₂ = 2^nd sowing on 03 December 2012) and S₃ = 3^rd sowing on 18 December 2012. Ploughing was followed by laddering in order to break clods as well as level the land. The experiment was laid out in a split plot design with three replications. Land was prepared by applying proper doses of manures and fertilizers which was recommended by BARI for wheat cultivation. Urea-220 kg ha^-1, TSP-180 kg ha^-1, MoP-50 kg ha^-1 and Gypsum-120 kg ha^-1 were applied. Total urea was split twice being the first dose was applied at sowing time and s
