Title of the technology: Introduction of Wheat-Jute-T. Aman cropping pattern

Year of innovation: 1993

2.

Indroduction: The Wheat-Jute-T. Aman cropping pattern is cultivated in almost all regions of Bangladesh. Farmers receive food as well as financial support from this pattern. Rice and wheat are monocotyledonous and have relatively shallow roots, whereas jute is dicotyledonous and has deep roots. As a result, when these crops are successively cultivated, nutrients can be supplied from both the shallow and deep portions of the soil, and fertilizers may be used properly. This cropping pattern was introduced through improved varieties and management in different AEZs of Bangladesh.

3.

Salient features of the technology:

a) Three crops might be grown on the same plot of land in a single year using this pattern.

b) Growing three different types of crops improves the natural or physical condition of the soil and increases productivity.

c) Insects and diseases affecting these three crops are almost different. That is why, it is resisted in this cropping system. Since successive crops are similar, insects and diseases from those crops can transmit easily to the subsequent crops.

d) This cropping system can meet a variety of needs of the farmer.

Suitability of the technology:

This cropping pattern is suitable for medium-high, rainfed fields. Through research projects in Manikganj, Kishoreganj, Mymensingh, and Faridpur from 1981 to 1989, the utility of this technology was verified.

6.

Economic benefit of the technology and role for livelihood development:

The improved pattern yielded an average yield of 1.44 ton, 2.15 ton, and 2.94 ton per hectare of wheat, jute, and T. aman, respectively. These yields were 33, 25, and 27% higher than those produced by the conventional pattern, respectively.
