Abstract: The study was conducted at the farmers’ field of Bhaluka, Mymensingh to evaluate the agro-economic performance of Jute-T.aman-Cucumber cropping pattern against farmers’ existing pattern Jute-T.aman-Fallow through incorporation of modern high yielding varieties and improved management practices for crop production during 2016 and 2017. Two cropping pattern viz., Jute-T.aman-Cucumber improved pattern and Jute-T.aman-Fallow farmers’ existing pattern were the treatments variables of the experiment. The experiment was laid out in randomized complete block design with five dispersed replications in farmers’ condition. Mean data showed that the improved management practices for Jute-T.aman-Cucumber cropping pattern provided higher rice equivalent yield (16.86 t ha-1yr.-1), production efficiency (76.07 kg ha-1 day-1) and land utilization index (77.81 %) over farmers existing pattern Jute-T.aman rice-Fallow. Average gross return Tk. 291105 ha-1 and gross margin Tk. 118355 ha-1) of improved pattern were 72% and 130 % higher, respectively compared to that of farmers’ pattern with only 47 % extra cost. The marginal benefit cost ratio, land utilization index and production efficiency indicated the superiority of the improved pattern over the farmers’ practices.
