Abstract/ Executive Summary:

The study was conducted on effect of supplemental irrigation for both MV and local aromatic rice cultivation in T. Aman season. The result showed that the rainfall distribution pattern during the growing season of rice cultivation was uniform. As a result rainfed condition gave satisfactory yield. The plot with supplemental irrigation gave slightly higher yield than rainfed condition.

Keywords: Supplemental irrigation, MV and local aromatic rice, Aman season

Location: BRRI farm, Gazipur

Start Date: 01-07-2008

End Date: 30-06-2009

Program Area: Crop-Soil-Water Management

Commodity: Supplemental irrigation

Objectives:

• To quantify amount of water needed for MV and local aromatic rice cultivation • To determine WUE by practicing AWD for MV and local aromatic rice cultivation • To determine the productivity and profitability of AWD for MV and local aromatic rice cultivation

Methodology:

The experiment was conducted in medium and high land in Aman season. The treatment comprised four aromatic varieties in split plot design with water treatment in main plot and four aromatic varieties in sub plot replicated three times. The water treatments were: I₁=Rainfed condition I₂=Irrigation when water level is 15 cm below the soil surface I₃= Irrigation when water level is 30 cm below the soil surface The four aromatic varieties were BRRI dhan34, BRRI dhan37, BRRI dhan38 and local aromatic variety Kalizira.
