Abstract/ Executive Summary:

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%.

Objectives:

To overview the existing cropping patterns, crops diversity and cropping intensity in Rajshahi region.

Methodology:

Thirty-two upazilas of Rajshahi, Naogaon, Chapainawabganj and Natore districts under Rajshahi agricultural region were the locale of this study. Data were collected using double stage procedure. At initial stage, data were collected through pre-tested semi- structured questionnaire from 32 pre-assigned Sub-Assistant Agriculture Officers (SAAO) of each upazila during February 2016 at upazila level. The SAAOs were purposively preselected by Agriculture Extension Officers (AEO), Additional Agriculture Officer (AAO) and Upazila Agriculture Officer (UAO) or altogether. Prior to data collection, the pre- tested questionnaire was explained along with proper guidelines to the AEOs or UAOs or both and handed over to them at each Deputy Director’s office of the Directorate of Agricultural Extension (DAE) during monthly meeting for the sake of accurate data collection. The scientists of RFS Division collected the filled questionnaires. They also checked and analyzed those to find the inconsistencies of the supplied data before validation workshop. All the inconsistencies among the information were documented. The collected data along with documented inconsistencies were discussed in district level workshop for necessary correction and validation. Second stage of data collection was daylong data validation workshop at district level. The workshop dates were 25 April for Naogaon; 26 April for Natore; 16 August for Rajshahi; and 17 August 2016 for Chapainawabganj. Four field-workers i.e. one SAPPO and three SAAOs experienced and engaged in crop-based data documentation, all officers from all upazilas viz UAOs, AEOs, AAEOs, DD (DAE), DD (Horticulture), DD of Seed Certification Agency, DTO and ADDs, one representative from Agricultural Training Institute (ATI) and scientists of BRRI regional station, Kushtia, and Rajshahi participated in the data validation workshop. The number of participants of validation workshop ranged from 56 to 98 in each district. All the participants were divided into three to four groups for data validation. Each group was facilitated by two RFSD scientists to finalize and validate the data and authenticated data were captured. Crop diversity index was calculated by using the following equation described by Kshirsagar et al. (1997). It approaches unity as the level of diversity increases. Compilation and processing of collected data were done using Micro Soft Excel programme. Descriptive statistics were used to facilitate the presentation of the findings.

Achievement/Findings:

The net cropped area of the Rajshahi region is 693,620 ha. Crops occupying the particular land for round the year were considered under annual crops. The major annual crops reported in the region were pineapple, sugarcane, banana, papaya, betel leaf, ginger and turmeric. The annual crops area in different upazilas ranged from 40 to 7,940 ha. The annual crops area accounted only 5.96% of the net cropped area (NCA) in the region. At a glance the region possesses 10.73% single cropped area (SCA), 48.38% double cropped area (DCA), 33.58% triple cropped area (TCA). The quadruple cropped area QCA also exists as a very negligible portion (0.67%) and is limited in only six upazilas viz Badalgachhi, Manda, Mohadevpur and Raninagar of Naogaon district, and Bagha and Mohanpur of Rajshahi district. Compared with DCA and TCA the SCA remained much lower in each and every upazilas. In Rajshahi region, DCA remained higher in Singra upazila of Natore district followed by Godagari upazila of Rajshahi district. Chapainawabganj sadar and Shibganj upazilas are the exceptions where TCA occupied the biggest share of NCA.
