Abstract/ Executive Summary:

The study was undertaken to find out variety wise adoption rate of lentil in Bangladesh through expert elicitation procedure. Many varieties have been developed by BARI and BINA but in details of varietal information and adoption information database was not developed which is very important and valuable for the scientist and policy planner. From all over the Bangladesh, 12 experts was invited to share their valuable knowledge and experience on lentil cultivation and adoption in the country. The average age of the experts were 51 yrs and average experience on lentil adoption was 21 yrs. The lentil expert informed that 16 major varieties are adopted by the farmers in the recent year (2013-14). Among those varieties, BARI Masur-6 covered highest cultivated area (54,642 ha) which shared 30.04% of total lentil cultivated area. BARI Masur-4, BARI Masur-3 and BARI Masur-5 ranked 2nd, 3rd and 4th position according to the share of cultivated area covered. The seed production information showed that BADC the only lentil seed producer supplied 2151 mt of lentil seed in the year 2009-2013.The adoption of variety BARI Masur-6 increased due to its high yield attribute. The another variety BARI Masur-4 and BARI Masur-3 adoption increased due to its high yield, resistant to rust disease attributes which showed increasing adoption path among the expert. Satisfying higher demand for lentil consumption and ensuring food security through providing alternative to winter crops are the major concerning issue of the policy planner and the scientist. To ensure nutrition security in the country, it is very important to encourage and support the farmers to grow more lentil through providing improved cultivation technology to the farmers.

Keywords: Economics, Expert elicitation, Varietal adoption

Location: Rajshahi, Jessore, Barisal zone of Bangladesh

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Socio-economic and Policy

Non-commodity: Adoption of technology

Objectives:

i)   To document and process on varietal release at the national level
ii)   To find out variety wise adoption rate of lentil in Bangladesh and
iii)   To suggest policy implications from the above.

Methodology:

Data and data sources
The main approach is to assemble the relevant data for the most recent years from multiple sources such as national data sources (BBS, DAE), Annual Report of pulse research center of BARI, BARI & BINA annual report, Books of BARI developed crop varieties, consultation with related scientists and expert elicitation (EE) workshop.

Details of experts
A panel of experts knowledgeable about the adoption of lentil cultivars in the zones (ecosystem, season or administrative zone) was formed. Typically, a panel consisted of 12 experts including scientists (breeders, agronomists, and agricultural economists), extension workers, seed producers & traders, development worker and farmers about lentil production systems in the locality. Lentil is grown in most of the areas of Bangladesh. As per the statistics of DAE, the total area under lentil cultivation is 0.18 million hectare with the production of 2.16 million tons during 2013-14. The adoption study of lentil variety has been taken-up top four zones of Rajshahi, Jessore, Barisal zone of Bangladesh because they were the top producer’s zones of lentil occupying an area 92.36% and production of about 94% during 2013-14.

Achievement/Findings:

Very valuable information about lentil was collected through the elicitation of 12 experts who had expertise of different discipline of pulse sector through involving in lentil research and extension at different corners of the country. On an average, the expert’s age was 51 years, and had 21 years of experience on lentil research and extension. The adoption rate information provided by experts revealed that 12 different varieties were cultivated on highest percentage of cultivation area. Among those cultivated varieties, finding of the EE workshop revealed that the farmers adopted lentil varieties such as BARI Masur-6, BARI Masur-4 and BARI Masur- 3 etc. BARI Masur-6 was highly adopted variety (30.04%) followed by BARI Masur-4 (23.41%), BARI Masur-3 (13.1%), BARI Masur-5 (7.4%), BARI Masur-7 (4.79%), Binamasur-5 (1.94%), BARI Masur-2 (1.87%), and BARI Masur-1 (1.7%). Others varieties such as Binamasur-1, Binamasur-2 and Binamasur-3 etc. occupied rest of the total lentil areas in Bangladesh. A difference was found between the percentage of adoption area mentioned by the experts and percentage found in secondary source. The difference in adoption percentage might be due to different study year and also difference in study area location. Seed production information is not publicly available. In spite of that, the breeder seed information from BADC showed that BARI Masur-3 increased sharply but BARI Masur-4 gradually decreased.
The adoption of variety BARI Masur-6 increased due to its high yielder attribute. The another variety BARI Masur-4 and BARI Masur-3 adoption increased due to its high yield, resistant to rust disease attributes.
Variety developed by NARS with the support of ICARDA has a small share in adoption status. This indicated that there is a very wide scope to give more emphasis on varietal improvement of lentil by NARS. To ensure nutrition security in the country, it is very important to encourage and support the farmers to grow more lentil through providing improved cultivation technology to the farmers.
