Abstract/ Executive Summary:

The present study was undertaken in two production environments in order to estimate the level of growth in area and production of rice and maize over the years, and to assess the level of changes in area under different crops. Applying both descriptive and inferential statistics, the study revealed that, the growth in acreage and production of maize had much accelerated rate compared to that for rice over the period 1987-88 towards 1996-97 and in the subsequent periods. In the favourable environment, the acreage under MV Boro increased by 18% in 2008-09 compared to 2004-05. In rabi season, the area under maize increased to 46% and 21% in drought prone and favourable areas, respectively. The magnitude of area changes from rice to non-rice crops under favourable area was negative. Per hectare cost of maize cultivation in drought prone area was about 13% higher than that of favourable area resulting in better net return in maize production under favourable area. Family labour, farm size and market accessibility were the important determining factors for devoting areas to maize cultivation instead of rice.

Objectives:

To estimate the level of growth in area and production of rice and maize over the years.
To asses the level of changes in area under different crops over the years in some selected areas of Bangladesh.
To determine the profitability differences in producing maize in the selected production environments.
To examine the relative contribution of different factors influencing area devotion to maize cultivation in the selected areas of Bangladesh.

Methodology:

Both primary and secondary data were used in this study. As such, sample survey was carried out in four districts in order to capture two production environments, i.e. favourable and drought-prone environments. Two districts under each environment were selected purposively. Categorically, Bogra and Dinajpur were taken under favourable situation, while Chapai-Nawabgonj and Chuadanga were selected under drought-prone environment. One Upazila from each district and two villages under each Upazila were selected purposively. From a comprehensive list of maize growers in each village, twenty farms were selected randomly. Finally, a total of 160 farms were selected for carrying out the sample survey from which the required primary data were generated through using structured questionnaire. The survey was carried out during both rabi and kharif seasons of 2009. The required secondary data were collected from different sources, such as BBS, DAE, and IMMP (Integrated Maize Management Program). Both descriptive and inferential statistics were employed in analyzing the generated data.
