An Experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from October 2012 to April 2013 to study the yield advantages and economic gains from the variable row arrangements of lentil and chickpea as intercropping within the base crop maize. Seven treatments were included in the study viz.; - T1 (sole maize), T2 (sole lentil), T3 (sole chickpea), T4 (one row of maize followed by one row of lentil intercropping), T5 (one row of maize followed by one row of chickpea intercropping), T6 (one row of maize followed by two rows of lentil intercropping) and T7 (one row of maize followed by two rows of chickpea intercropping). In all the sole crop treatments the recommended plant population of maize, lentil and chickpea was maintained. Results indicated that seed yield of maize was significantly affected by the maize-lentil/chickpea intercropping systems. The highest seed yield was obtained from T1 (sole maize) (7490.67 kg/ha). Maize yield gradually decreased in lentil and chickpea rows. In intercropping situation the highest seed yield (4716.33 kg/ha) was obtained from T5 (one row of maize followed by one row of chickpea intercropping) which was similar to that of T6 (one row of maize followed by two rows of lentil intercropping) (4677.67 kg/ha). The lowest seed yield (3900 kg/ha) was obtained from the T7 (one row of maize followed by two rows of chickpea intercropping). The highest maize equivalent yield (10054.77 kg/ha) was obtained from the treatment T6 (one row of maize followed by two rows of lentil intercropping). Treatment T6 (one row of maize followed by two rows of lentil intercropping) produced the highest LER. Economic analysis of the different treatments showed that highest gross return (180996.80 Tk/ha) and the highest net return (108447.89 Tk/ha) and BCR (2.49) were found in T6 (one row of maize followed by two rows of lentil intercropping). Therefore, present study suggests that intercroppinDownload
