Abstract/ Executive Summary:

The rainfall and rainy days in T. aman season of selected 4 districts, which revealed variation of rainfall and rainy days among districts. In partial budgeting analysis, supplemental irrigation vs. rainfed T. aman production showed that supplemental irrigation T. amam cultivation was profitable and increased per hectare profit of Tk. 6870, Tk. 5752, Tk. 11130 & Tk. 7935 in Rangpur, Thakurgoan, Rajshahi, & Natore areas respectively, which indicated that by practicing supplemental irrigation Rajshahi area farmers eared more gross margin than other areas. It is revealed the major constraints to supplemental irrigation reported by DAE officials and farmers, which indicated that opinion about constraints to supplemental irrigation, were same for DAE personnel and farmers but the degree of respond were different.

Keywords: Economics of irrigation, Supplemental irrigation, Rice production.

Location: Rangpur, Thakurgoan, Rajshahi, & Natore

Start Date: 01-07-2004

End Date: 30-06-2005

Program Area: Socio-economic and Policy

Commodity: Supplemental irrigation

Objectives:

Supplemental irrigation and its impact on T.Aman rice production in Bangladesh

Methodology:

Primary survey data were used for this study. For this purpose, a pre-tested survey questionnaire was used for interviewing the farmers as well as the DAE officials for district level data. The questionnaire contains information related to adoption of supplemental irrigation, utilization status of DTW and STW for supplemental irrigation purpose, cost and return for different T. aman production, constraints to supplemental irrigation and provable suggestions for wide adoption of supplemental irrigation. A total of 60 farmers from 4 districts (Rangpur, Thakurgoan, Rajshahi, & Natore) were interviewed. The trend of irrigation devices use and area coverage of T. aman under supplemental irrigation for the selected district which indicated that both irrigation devices and area under supplemental irrigation increasing year to year. STWs were commonly used for supplemental irrigation purpose in Rangpur Thakurgoan & Natore areas. But in Rajshahi area DTW, STW & LLP were used for supplemental irrigation purpose. The district level and farm level T. aman area under supplemental irrigation, which indicated that both district and farm level supplemental irrigation coverage are expanding year to year. To determine economic implication of supplemental irrigation on T. aman rice, a partial budgeting analysis was carried out.

Achievement/Findings:

In our country sufficient rainfall is occurred during T.aman season, but it is not equally distributed through out the season. Thus, some time T.aman crop suffer moisture stress during vegetative and reproductive stage, which decrease yield and farm income. Therefore, timely application of supplemental irrigation is essential for optimal T.aman production. Recent field survey showed that per hectare profit from two of supplemental irrigation were Tk. 6870, Tk. 5752, and Tk. 11130 & Tk. 7935 in Rangpur, Thakurgoan, Rajshahi, & Natore areas respectively. Through DAE activities and overcoming constraints to supplemental irrigation, farmers awareness toward supplemental irrigation on T.aman production could be increased and there by increase yield, farm income and livelihoods
