Abstract/ Executive Summary:

A study was conducted to find out the rice varietal diversity in some selected Haor areas of Sunamganj district during January to march, 2008. Data were collected from 102 farmers of 6 villages of Sunamganj district. It was revealed that majority (65.69%) of the farmers cultivated 2 to 3 rice varieties, 26.47% farmers cultivated single variety and only 7.84% farmers cultivated 4 to 5 varieties. Among the varieties, BRRI dhan29 ranked first in respect of percent of cultivated farmers (92.20%) and areas (58.30%) followed by BR19. Overwhelming, majority (69.30%) of the farmers had low to moderate rice varietal diversity while 26.47% had no rice varietal diversity and only 3.92% farmers had high rice varietal diversity.

Keywords: Rice varietal diversity, Farmer, Haor

Location: Some selected Haor areas of Sunamganj district

Start Date: 00-01-2008

End Date: 00-03-2008

Program Area: Conservation and Biodiversity

Commodity: Rice

Objectives:

Objective of the study was to describe and to ascertain the rice varietal diversity in Haor areas of Suanamganj district of Bangladesh

Methodology:

Data were collected through multistage sampling procedure from six villages of Sunamganj district. Initially, two Upazilas were selected randomly from 12 Upazialas. In the second stage, a union was selected randomly from each of Tahirpur and Sunamganj sadar upazila. In the third stage, three villages were selected from each selected union by using random number. The selected villages were pataboka, Manik khola and Vabanipur of Dakshin Sreepur union under Taherpur upazila and Bahadurpur, Neelpur and Haluargaon of Lakshmansree union under Sunamganj sadar upazila. Finally, 17 farmers were selected by using random number from each selected village. Thus a total of 102 farmers constituted the sample of this study. Data were collected through pre-tested structured interview schedule by face-to-face interview procedure during January to March, 2008. Variety is simply understood as a crop population recognized by farmers and encompasses land races that have been grown and selected by farmers for many years, including modern varieties that meet the traits of being distinct, uniform and stable. Rice varietal diversity refers to the existence of diversity of rice varieties in farmer’s field. Rice Varietal diversity was measured through rice varietal diversity index (VDI). The operational definition of rice varietal diversity index (VDI) for a particular farmer was one minus of the squared sum of the proportional area planted to each variety and rice varietal diversity index (VDI) for a particular farmer was measured by using the formula. The index could range from 0 to 1, zero indicated no rice varietal diversity and 1 indicated very high rice varietal diversity for a farmer. Data were analyzed according to the objectives of this study with Excel and Statistical Package for Social Sciences (SPSS).

Achievement/Findings:

Due to the great concern of declining of rice biodiversity and overwhelming majority farmers of the study area possessed moderate, low or no rice varietal diversity, it is essential to conserve varietal diversity through arrangements of adequate program by the concern authorities for creating favorable attitude of farmers towards maintaining varietal diversity in rice and other crops. In this case, mass media campaign by popular TV channels, radio, cinema halls and news papers can play vital role. During, launching programmes for the promotion of diversity of rice as well as other crops emphasis are needed on in situ conservation. Timely availability of adequate amount of quality seeds of farmers’ desire rice varieties and other crops at farm level may enhance rice varietal diversity. Policy makers need to consider the matter and introduce program involving seed producers and suppliers for timely disposal of different variety’s seed to the farmers. It is also essential to aware the farmers about the benefits of high rice varietal diversity by the different government, nongovernment and private extension agencies.
