Abstract/ Executive Summary:

To expand the wheat area a field study was taken during rabi season to find the water requirement and optimum sowing time of wheat. Four sowing time were examined as Nov 15, Nov 22, Nov 30 and Dec 7. The results shows that Nov 15 sowing, gave highest yield (2960 kg/ha) and highest water productivity (9.13 kg/ha/mm) compared to other sowing date. Therefore, wheat sowing in Nov 15 was found suitable for both yield and water productivity aspects.

Keywords: Water requirement, Water use efficiency, Yield of wheat, Rice-wheat system

Location: Chuadanga sadar Upazila, Chuadanga

Start Date: 01-07-2000

End Date: 30-06-2001

Program Area: Crop-Soil-Water Management

Commodity: Water management

Objectives:

To determine the amount of water use and their respective water use efficiency for different sowing time of wheat
To determine the best option of wheat sowing time for achieving maximum yield

Methodology:

The experiment was conducted at farmers’ field in Chuadanga sadar Upazila. Treatments were: D₁= wheat sowing on Nov 15; D₂= wheat sowing on Nov 22; D₃= wheat sowing on Nov 30; D₄= wheat sowing on Dec 7. Five water treatments were followed: T₁=Irrigation at CRI stage (20 DAS); T₂= Irrigation at CRI and maximum tillering stage (20 and 40 DAS); T₃= Irrigation at CRI, maximum tillering and booting stage (20, 40 and 60 DAS); T₄= Four irrigation at 20, 35, 50 and 70 DAS; T₅=Five irrigation at 20, 35, 50, 65 and 80 DAS. The variety was sonalika and fertilizer rate was standard recommended dozes. The soil was sandy loam.

Achievement/Findings:

The results shows that Nov 15 sowing, gave highest yield (2960 kg/ha) and highest water productivity (9.13kg/ha/mm) compared to other sowing date.Under late sowing (Dec 7) the yield was only 1670 kg/ha. Therefore, wheat sowing in Nov 15 was found suitable for both yield and water productivity aspects.
