Abstract/ Executive Summary:

A survey was carried out in the district in two upazilas namely Nowabgonj Sadar and Shibgonj of the district of Nowabgonj .There were 16 demonstration blocks in the two upazilas of the district. Out of those 16 demonstration blocks, 6 blocks takting 3 from each Upazila were selected for the study The study revealed that there was no significant difference in agronomic practice and input use for blackgram cultivation both for BARImash-1 and local variety. But significant difference was found incase of yield between BARImash-1 and local variety, and it was found 35% higher for improved variety than local variety of blackgram. Result of multiple regression model using dummy variable shows that BARImash-1 had a positive significant impact on production of blackgram in the farmers fields. It also implies that in existing situation, if the local variety could be replaced by BARImash-1, per hectare Tk.4542.00 would increase production in monetary term.

Keywords: Economic Performance, Barimash-1, Production, Blackgram

Location: Nawbabganj district.

Start Date: 00-00-2000

End Date: 00-00-2001

Program Area: Socio-economic and Policy

Commodity: Black gram

Objectives:

1. To compare the economic performance of BARImash-1 and local variety at farm level.

2. To asses the varietal impact and evaluate farmers' attitude towards BARImash-1

3. To identify the constraints to the adoption of BARImash-1.

Methodology:

Nawbabganj district was selected for the study as one of the most potential areas for blackgram production. A survey was carried out in the district in two upazilas namely Nowabgonj Sadar and Shibgonj . There were 16 demonstration blocks in two upazila of the district. Out of those 16 demonstration blocks, 6 blocks takting 3 from each Upazila were selected for the study depending on convenience of communication. A total of 49 farmers were interviewed from these 6 blocks. Besides 49 farmers from outside the demonstration plots were also surveyed. Data were collected during Kharif-II season, 2000-2001. Finally, a total of 98 farmers were surveyed to fulfill the objectives of the study. In the demonstration block, the farmers cultivated BARImash-1 whereas non-demonstration farmers cultivated local variety of blackgram. Standard deviation and t-statistics were often used for this analysis. Moreover, to assess the varietal impact on blackgram production a Multiple Linear Regression Function was also used. Model was chosen on the basis of best fits. Multiple Linear Regression Function was as follows: Yj = b₀ + b₁X_1j +b₂X_2j + b₃X_3j + ----+b_nX_nj+Uij. where, Yj = Yield of jth product; b₀ = Intercept; b_i = Co-efficient of explanatory variables; I= 1,2,3, ----n; X_ij = ith variable inputs of jth product; I= 1,2,3,-------n; U_ij = Error term. so, the empirical function would be Y = b₀ + b₁X₁ + b₂X₂ + b₃X₃ + b₄X₄ +b₅X₅ + b₆X₆ + e. where, Y = Yield of blackgram (Tk ha^-1), b₀ = constant, X₁ = Animal power cost (Tk ha^-1), X₂ = Seed cost (Tk ha^-1), X₃ = Manure cost (Tk ha^-1), X₄ = Fertilizer cost (Tk ha^-1), X₅ = Human labour cost (Tk ha^-1), X₆ = Dummy variable, assuming that BARImash-1 = 1 and Local variety = 0, e = Error.

Achievement/Findings:

Result of multiple regression model using dummy variable showed that, BARImash-1 had a positive significant impact on the production of blackgram at the farmers fields. It also implied that, if the local variety could be replaced by BARImash-1, additional economic return @ Tk.4542/ha could be attained
