Banana based intercropping system in north-west part of Bangladesh

Abstract

An experiment was conducted to find out a suitable banana (Ranginsagar and Sabari) based intercrop combination of potato and mustard in the research field of Institute of Biological Science of Rajshahi University, Rajshahi-6205, during Rabi season of 2003-2004. Average over the two years, it revealed that the highest yield of banana was observed in Ranginsagar + potato (64.72 t ha -1) and the lowest in sole mustard (1.92 t ha-1). Combinations of Ranginsagar + potato intercropping showed better performance than other combination and sole crop in respect of gross return (Tk. 735219 ha-1), net return (Tk. 359794 ha-1) and benefit cost ratio (1.95). The highest land equivalent ratio (LER) was 1.82 in Ranginsagar + Potato followed by Sabari + potato (1.79) and the lowest in Sabari + mustard (1.60). The economic return was more in intercropping than all sole crops. © 2006 Asian Network for Scientific Information.
