Abstract/ Executive Summary:

A study was conducted to estimate the productivity gap in MV T.Aus rice between potential farm and actual farm as well as examine the factors responsible for MV T.Aus rice yield gaps in Chuadanga. In the Aus season, 80 demonstration plots managed by Department of Agriculture Extension and 80 farmers’ managed plots were selected from four villages of Chuadanga sadar upazila. Data were collected in two phases using structured questionnaire. Both tabular and statistical techniques were employed for analyzing the data. The analysis has further been extended to estimate the contribution of individual technical factors to the yield and the input-output relations. The average yield of MV Aus rice were 2.84 t/ha and 3.31 t/ha in the farmers’ plots and demonstration plots, respectively, indicating 17% yield gain in the demonstration plots. The production cost per hectare on full cost and cash cost basis were 16 and 1% higher, respectively, in the demonstration plots than that in the farmers’ plots. But the unit cost of production on full cost and cash cost basis were lower 0.60 and 15%, respectively, in the demonstration plots than that in the farmers’ plots. The benefit cost ratio (BCR) was also higher on full cost and cash cost basis in the demonstration plots compared to farmers’ plot. Analysis further indicated that there is ample scope of increasing modern Aus yield by 0.29 t/ha through adopting appropriate variety, timely sowing and proper irrigation as well as weeding at the farm level.

Objectives:

Specific Objectives

To estimate the productivity and profitability gap as well as input use differences in MV T.Aus rice between demonstration and farmers’ plots.
To examine the contribution of factors responsible for MV T.Aus rice yield gaps and assess farmers’ choice/preferences towards selecting modern Aus variety, and
To provide estimates on T.Aus yield loss as a vital factor of yield differentials at the farm level.

Methodology:

The study is based on the farm level information obtained through sample survey of 160 farmers under 4 villages named Khajura, Sangkarchandra, Hatikata, and Belapara under Chuadanga sadar upazila of Chuadanga district during 2010-11. Data were collected in two phases: crop cut data was collected before harvesting the MV Aus rice crop and the other information were collected during the growing period using pre-designed questionnaire. After collecting data, it was checked and edited properly. The Department of Agricultural Extension (DAE) had conducted demonstration on different farms under Chuadanga Sadar. In the Aus season, 80 demonstration plots and 80 farmers’ plots were randomly selected from those villages. All of the four varieties, such as BRRI dhan28, BR26, Purbachi, and Swarna were grown in both the farmers’ plots and demonstrations’ plots. Swarna was undertaken due to widely adopted by the farmers in the study areas. Data on yield, seed rate, fertilizer, labour use, price of different inputs, etc. were collected through interviewing the farmers. The collected data were coded, computed and tabulated and then analyzed for achieving the specified objectives of the study. Both tabular and statistical techniques were used for analyzing the data. In addition, partial budgeting analysis was done to determine the profitability gap. The difference between the yield of demonstration plots and farmers' plots have been estimated as they provide the measures of yield gap due to technological and other factors. The analysis has been extended further to estimate the contribution of individual technical factors to the yield and the output input relations on the following lines: Contribution of technical factors Based on the technical factors adopted in the demonstration and farmers’ plots during the period, different treatments have been devised to estimate the contribution of individual treatment factors. All the farmers were grouped into different treatments. Description of the treatments was given below: V₁= Improved variety (BRRI dhan28, BR26 and Purbachi) recommended in Bangladesh F₁= Recommended fertilizer rate V₀ = Introduced Improved variety Swarna (Indian variety) F₀ = Fertilizer rate other than recommended S₁ = Timely sowing (before 10 th June) I₁ = Inter cultural operations (two to three weeding after planting) S₀ = Late sowing (after 10 th June) I₀ = Less than two weeding after seeding R₁= Recommended seed rate (146-150 kg/ha) M₁ = Farmers used power tiller and tractor R₀ = Seed rate other than the recommended rate M₀ = Farmers not used power tiller and tractor.

Achievement/Findings:

Gap between demonstration plots and farmers’ plots were positive due to human labour, animal labour, power tiller, and fertilizer dose. It indicated that these factors were responsible for higher yield of MV T.Aus rice in demonstration plots as compared to farmers’ plots. The profitability analysis indicated that the gross return, net return, and benefit cost ratio were also higher in the demonstration plots than those of farmers’ plots although the total cost of cultivation were higher on full cost basis. Partial budgeting analysis also indicated that MV T.Aus rice cultivation was more profitable under demonstration plots compared to farmers’ plots. In the Aus season, weed is the most important constraint for yield loss followed by soil related stress (mainly organic matter deficiency). Among the varieties grown in this season, BRRI dhan28 is the most popular variety due to better taste and higher grain yield with wide yield difference between demonstration and farmers’ plots. The yield could be increased by adopting recommended technologies with management practices. The contribution of yield depends upon many factors, such as recommended variety, use of fertilizers, timely sowing/planting, and weeding for profitable growing of MV T. Aus rice. It was also observed that the high monetary returns were directly associated with the above technical factors.
