The project entitled "A study on the use of Agricultural Inputs for Major Crops in Bangladesh" was undertaken in October 1992. The 16 month field survey was conducted between mid February, 1992 and mid June, 1993. A long questionnaire with 59 columns was canvassed once a month in 9143 clusters of temporary crops. The average cluster size was 5 acres, each with an average 20 plots. The temporary crops include rice, jute, wheat, potato and sugercane.
The objective of the project is to find out farmers' practices on the use of agricultural inputs in temporary crops. Finding out of a relationship between the inputs used and the resultant outputs, that is, impact of inputs (individually and collectively) on outputs is aimed at. This will help determine an objective basis for planning of crop production, inputs supply and use and pricing.
This is the first survey of this kind. The size of the sample survey has been very large. About 2 lac plots involving interview of about 1.5 lac farmer4 every month were taken for the survey. The size of the questionnaire (with 59 questions) was also very large. On the other hand there was no provision of man-power except 6 officers and 8 staff for handling this survey. Initially the project suffered organisational difficulties due to man-power shortage. The project proforma was then revised and some staffmembers were added.
Since this is the first survey of its kind some conceptual mistakes, omissions and operational lapses were observed during processing the survey data. We hope that these lapses and omissions will not be repeated in future surveys.
A seperate report has been prepared for each major crop. The report contains tables of crop data with explanatory notes on each table. The regression tables and their analysis on the impact of each input on production merit special attention.
I am thankful for the wholehearted co-operation and willing disclosure of facts by our farmers.
I want to express my sincere thanks to Mr. M.A. Jalil Bhuiyan, Project Director and other officers and staff of the Project who have worked very hard.
Kind of Data
Sample survey data [ssd]
In the original Project Profon-na (P.P.) 12 monthly surveys were proposed. In the revised P.P. the survey was extended by 4 months to cover the missed input data of cultivation & sowing stages in respect of major crops like boro, wheat and potato. The survey was conducted on monthly basis through observing the clusters and crop condition in each plot and inteviewing the operator cultivators. It may be mentioned here that the survey filed work started in Falgun, 1395 Bangla year corresponding to mid-February, 1989.
Only five major crops namely Rice (all varieties), Jute (two varieties), wheat (two varieties), potato and sugarcane were studied. National, regional or sub-regional estimation of inputs or outputs were not included in the scope of the survey. Data on crop area, inputs used and outputs produced were collected only from 9143 clusters in respect of five major crops. These data were processed and tabulated as per predesigned tabulation plan.

Stratified random survey design was the sample design for selecting the clusters. All the 9143 operated clusters of the existing stratified random clusters design were studied between mid February, 1989 and mid June, 1990 once every month.
Dates of Data Collection (YYYY/MM/DD)
Mode of data collection
Upazila statistical officers were responsible for close supervision of the filed work. Regional statistical officers also travelled within their regions during the survey period to supervise field work. Officers from the project-headquarters frequently visited clusters to monitor progress of field worki During the,visits the officers identified the errors/mistakes committed by enumerators and made corrections on the spot if.necessary.
Type of Research Instrument
Pre-test of questionnaire :
BeIre finalisation of the questionnaire designed for the survey, a Pre-Test was conducted in eight upazilas of four divisions during the period from 15-11-92 to 22-11 -92. Four Deputy Directors were assigned for conducting the Pre-Test in one selected cluster in each of the following eight upazilas.
The objectives of the Pre-test were :-
1. To test suitability of the questionnaire.
2. To test and verily coverage of items of the questionnaire.
3. To identify the questions which respondents found difficult to answer and to determine if enumerators had any difliculty in understanding the concepts, definitions or terminologies used in the questionnaire.
4. To assess respondents' willingness and co-operation.
5. To estimate time required for filling in the questionnaire.
The results obtained in the Pre-Test were discused by the Technical Committee and the questionnaire modified.

Data processing is the most important and vital part of a survey/census operation. On receipt of the filled-in schedules, these were arranged by upazila, district and region. Manual editing was taken up with the help of the staff of Agriculture Statistic Wing. After completion of the manual editing, the verification of the geo-àode of the schedules was undertaken and completed.
On completion of geo-code verification schedules were sent to Computer and Data Processing Wing of BBS for processing by the Main-frame computer. Under the supervision of the Deputy Director (System) of the project the information of the schedules were punched in Mini computer and stored in magnetic tape. An error list was printed out and supplied to the project office for correction. The staff of the project reviewed the inconsistancies and corrected them.
