With a view to document the existing cropping patterns, cropping intensity and crop diversity, a study was carried out over all the upazilas of Bogra agricultural region during 2015-16. A pre-tested semi-structured questionnaire was properly used for this purpose. In the findings it was recorded that 21.88% of net cropped area (NCA) of the region was occupied by the cropping pattern Boro−Fallow−T. Aman. This pattern was found to be distributed over 27 upazilas out of 35. The second largest area, 13.26% of NCA, was covered by Potato−Boro−T. Aman, which was spread over 17 upazilas. A total of 177 cropping patterns were identified in the whole region in this investigation. The highest number of cropping patterns was identified 36 in Nandigram upazila and the lowest was six in Dupchachia and Kahalu upazila of Bogra district. The lowest crop diversity index (CDI) was reported 0.718 in Raiganj upazila of Sirajganj district followed by 0.734 in Kalai of Joypurhat. The highest value of CDI was observed 0.978 in Pabna sadar followed by 0.972 in Bera upazila. The range of cropping intensity values was recorded 183-291%. The maximum value was for Khetlal upazila of Joypurhat district and minimum for Bera of Pabna. As a whole the CDI of Bogra region was calculated 0.966 and the average cropping intensity at regional level was 234%.Bangladesh Rice j. 2017, 21(2): 73-90

With this view, a survey-work was implemented over all the upazilas of Barisal region during 2016. A pre-tested semi-structured questionnaire was used as tool to document the existing cropping patterns, cropping intensity and crop diversity of the area. In the current investigation, 103 cropping patterns were identified. The highest number of cropping patterns 40 was found in Burhanuddin upazila of Bhola district and the lowest eight was in Betagi and Taltali of Barguna. The most dominant cropping pattern single T. Aman occupied 13.40% of net cropped area (NCA) of the region with its distribution over 33 upazilas out of 42. The second largest area, 10.44% of NCA, was covered by Boro−Fallow− T. Aman, which was spread out over 32 upazilas. The lowest crop diversity index (CDI) was recorded 0.221 in Agailjhara of Barisal district followed by 0.598 in Bhandaria of Pirojpur.

Comilla region is highly diverse in respect to topography, agro-ecology, land-use pattern and cropping systems. Planning of agricultural development largely depends on the reliable and comprehensive statistics of the existing cropping patterns, cropping intensity and crop diversity of a particular area, which will provide guideline to our policy makers, researchers, extensionists and development workers. The study was conducted over all 33 upazilas of Comilla region during 2016 using pre-tested semistructured questionnaire with a view to document the existing cropping patterns, cropping intensity and crop diversity. From the present study it was observed that 73.56% of net cropped area (NCA) is covered by exclusive rice cropping systems whereas deep water rice cropping system occupied 16.09% of the regional NCA. The most dominant cropping pattern single Boro alone occupied 26.18% of NCA with its distribution over 30 out of 33 upazilas. The second largest area, 19.93% of NCA, was covered by Boro−Fallow−T. Aman cropping pattern, which was spread over 25 upazilas. One hundred and forty-six cropping patterns were identified in the whole region under this investigation.

Attempts have been made in this paper to overview the existing cropping patterns, crops diversity and cropping intensity in Rajshahi region. The study was conducted in all the upazilas of four districts of Rajshahi region during 2014-15 using pre-tested semi-structured questionnaires. The most predominating crop in this area was rice where exclusive rice based patterns occupied 40.48% of NCA. Boro-Fallow-T. Aman was the dominant cropping pattern, occupied 22.83% of NCA in 27 upazilas out of 32. The second dominant cropping pattern in Rajshahi region was Boro-Fallow-Fallow. It occupied 7.23% of NCA of the region and existed in 28 upazilas. Wheat-Fallow-T. Aman was the 3rd dominant pattern and practiced in 4.34% of the NCA in 14 upazilas. The data also revealed that the wheat based patterns stands for 14.7% of NCA. Mustard-Boro-T. Aman was the 4th dominant cropping pattern. A total of 172 cropping patterns were recognized in this region and the maximum (36) numbers of cropping patterns were identified in Paba upazila nearly followed by Durgapur (35) and Chapainawabganj upazila (34) while the lower numbers of cropping patterns were identified in Charghat (11) followed by Bagha (12) upazila of Rajshahi district. The range of cropping intensity values was recorded 171−253%. The maximum value was for Badalgachhi of Naogaon district and minimum for Bagha of Rajshahi district. The overall CDI of Rajshahi region was calculated 0.970 and the average cropping intensity at regional level was 218%.Bangladesh Rice j. 2017, 21(2): 237-254
