The study was executed during rabi season of 2020-21 and 2021-22 at the research field of Agricultural Research Station, BARI, Rajbari, Dinajpur (Latitude: 25038̍7.3̎ N, Longitude: 88039̍5.65̎ E) to evaluate how well intercropping potatoes with long-duration maize performs economically. Six treatments viz. T1= Sole maize (60cm×20cm), T2= Maize planting (60cm×20cm) + 1 row potato in between two maize rows, T3= Maize paired row (30cm/120cm/30cm × 20cm) + 1 row potato, T4= Maize paired row (30cm/120cm/30cm×20cm) +2 rows potato, T5=Maize paired row (30cm/120cm/30cm × 20cm) +3 rows potato and T6= Sole potato (60cm ×25cm). Among the intercropping treatments, the highest maize yield was recorded in Maize paired row (30cm/120cm/30cm × 20cm) +1 row potato (T3). In contrast, the highest potato yield was also achieved in T5 (Maize paired row (30cm/120cm/30cm × 20cm) +3 rows potato), indicating its superior productivity. From an economic perspective, the highest gross return, gross margin, and benefit-cost ratio (BCR) were recorded in T5 (maize paired row with 3 rows of potato), while the lowest values were observed in sole maize cropping (T1). These results highlight the advantages of intercropping, particularly in systems combining maize and potato, for improving yields and economic returns compared to sole cropping.
