Abstract/ Executive Summary:

This study was conducted to examine the relationship of climatic variables and aman rice cultivation area and production at six regions (Rajshahi, Sylhet, Khulna, Barisal, Dhaka and Chittagong) of Bangladesh considering 30 (1972-200I) years or climatic data (temperature, rainfall, relative humidity and sunshine) and aman rice cultivated area and production. Evidence showed that the aman rice cultivated area and production were recorded increasing trends during the studied period. Area under cultivation in every region showed a highly significant relationship whereas other parameters showed less variable relations with aman rice production concerning the regions. The production damaged in the years of 1974, 1987, 1988 and 1998 by excessive rainfall and catastrophic flood and in the year of 1972 by deficit rainfall. The information produced may serve not only as a guide to the selection of proper site for aman. rice production but also the most desirable period for sowing and harvesting.

Non-commodity: Data collection and collation

Objectives:

To examine the relationship of climatic variables and aman rice cultivation area and production at six regions (Rajshahi, Sylhet, Khulna, Barisal, Dhaka and Chittagong) of Bangladesh

Methodology:

Data were collected from Bangladesh Meteorological Department (BMD) and Bangladesh Agricultural Research Council (BARC), Dhaka. Monthly mean data of different climatic elements such as maximum temperature (⁰C), minimum temperature (^oC), rainfall (mm), relative humidity (%) and sunshine (hr) at different regions (Rajshahi, Sylhet, Khulna, Barisal. Dhaka and Chittagong) over Bangladesh for the period of January 1972 to December 2001 (i.e. 30 years) were used in this study. The yearly data on aman rice such as cultivated area (ha), production (t) and yield (t/ha) have been obtained from Yearbook of Agricultural Statistics of Bangladesh (BBS, 1972-2001). The aggregated figures of local and modern varieties were used for present analysis. Crop-climate relationship was investigated on the basis of cropping season of aman rice.

Achievement/Findings:

Increasing trends of aman rice production were showed in different areas during 1972-2001. It might be due to cultivation of modern variety, improved irrigation system and modern technology. But in Dhaka region aman rice production was decreased because of shifting aman rice area to boro rice cultivated area during the said period. The production damaged in the years of 1974, 1987, 1988 and 1998 by excessive rainfall and catastrophic flood and in the year of 1972 by deficit rainfall. Aman rice cultivated area and production showed highly significant positive relationship in different areas except Rajshahi region.
