Abstract/ Executive Summary:

An attempt was taken to transform Aman-fallow-Boro cropping pattern into Aman-rapeseed and mustard-Boro for three years beginning from Rabi 2011-12. Two components viz. Bangladesh Agricultural University, Mymensingh (BAU) and Bittohin Chashi Somaj Kallayan Sangstha (BCSKS) executed the programme under the leadership of BAU. Three upazillas viz. Mymensingh Sadar, Muktagacha & Haluaghat of Mymensingh district were under BAU component. Whereas, the upazillas Bagha of Rajshahi, Ishwardi of Pabna and Lalpur of Natore districts were under BCSKS component. A total of 1200 farmers (300+400+500 for 1st, 2nd & 3rd years) were taken into consideration to grow rapeseed and mustard in between Aman & Boro. Each of the farmers were provided with 1kg rapeseed and mustard seeds, necessary fertilizers, insecticide, fungicide & irrigation costs. Five rapeseed and mustard varieties namely BARI sarisha 14 & 15, BINA sarisha 4 & 7 and Unnata Tori 7 were used. Before rapeseed and mustard cultivation, all the farmers grew Aman rice &Boro rice after harvesting it. Among the five rapeseed and mustard varieties BARI sarisha 14 & 15, BINA sarisha 4 and Unnata Tori 7 were found to be suitable for the cropping pattern Aman-rapeseed and mustard-Boro. These varieties matured between 76.9 to 84.1 days. Per hectare seed yield of the varieties ranged from 1266.5 kg (Unnata Tori 7) to 1822.0 kg (BARI sarisha 14) with an average of 1544.6 kg. On an average per hectare cost of production, gross income & gross return from rapeseed and mustard were tk. 27770, 78180 and 50471, respectively. On an average, over three years gross income and gross return obtained from Aman and Boro rice were tk. 52,273 &22237 and tk. 71,138 & 30,935 per hectare, respectively. Thus, an additional income of tk. 50471 obtained by the farmers for growing rapeseed and mustard in between Aman & Boro over that of Aman & Boro only, and cropping intensity of the farmers raised into 300%.

Program Area: Crop-Soil-Water Management

Commodity: Mustard, Rice

Objectives:

To feed the ever growing people from the continuously decreasing cultivable land there is no other way but to increase cropping intensity of the country.

Methodology:

An attempt was taken to transform Aman-Fallow-Boro cropping pattern into Aman-Rapeseed and mustard-Boro for increasing cropping intensity, oilseed production of the country as well as net income of the farmers by using short duration aman rice and also short duration rapeseed and mustard varieties. With the view point 1200 farmers were selected over three years June, 2011 to may 2014 from the upazillas of Mymensingh sadar, Muktagacha and Haluaghat of Mymensingh district (Bangladesh Agricultural University (BAU) Component) and Ishwardi, Bagha and Lalpur upazillas of Pabna, Rajshi and Natore districts (Bittohin Chashi Somaj kallayan Sangstha (BCSKS) component), respectively. During farmer selection priority was given to the interested ones who will follow the cropping pattern Aman- Rapeseed and mustard-Boro. The selected farmers were trained about general pattern of livelihood, calories and nutritional requirements of a person, sources of calories and nutrition, present cropping pattern and cropping intensity of the country, future programs to be taken, quality seed production, distribution and use etc. During training, three technology sheets covering Aman, rapeseed and mustard & Boro were distributed. In addition of the farmers 37 extension service providers were trained and DAE/BADC/SCA personnel’s were also present. Each of the selected farmers were provided with 1kg rapeseed and mustard seeds, fertilizers, fund for insecticide & fungicide. The rapeseed and mustard varieties used were BARI sarisha 14, 15; BINA sarisha 4, 7 and Unnata Tori 7. For collecting data on various aspects a questionnaire/data collection sheet was prepared. Before going for data collection the data collectors/ Field assistants were also trained for appropriate and uniform data collection.

Achievement/Findings:

At times rapeseed and mustard was considered as a major crop but now-a-days it is considered as a minor one. As a result less attention has been given for its improvement. Once developed varieties of this crop was released through a long and appropriate procedure of the NSB. But now -a-days it is registered through a short-cut process. Once BADC paid much attention for its seed multiplication and DAE for its demonstration, dissemination etc. But now this activity has been slowed down. So, the country is not getting suitable varieties as required and the farmers are not much aware about the newly developed varieties and they are not getting quality seeds adequately. On the other hand, the land used during the rabi season are covered by so many crops in addition of rapeseed and mustard. So rapeseed and mustard as a crop has to complete intensively with many other crops and its return was found to be a bit less from some other rabi crops. So, the farmer has no other way to leave the crop slowly. In such a situation the present study has been started functioning, that is incorporation of rapeseed and mustard between Aman and Boro rice. If a considerable area of land remains fallow between Aman and Boro can be taken into rapeseed and mustard cultivation, then the country will be benefited enormously in various ways. The research findings indicated that Aman-rapeseed and mustard-Boro cropping pattern is applicable in some areas of Bangladesh. This will increase oilseed production of the country as well as total income of the farmers.

To establish the cropping pattern Aman-rapeseed and mustard-Boro throughout the country intensively programme should be taken involving research organizations like BAU, BARI, BINA etc.; seed multiplication organization like BADC, demonstration and seed distribution organization like DAE and some NGOs of the country.
