An experiment was done to determine the best intercropping methods for maximizing land utilization while also enhancing overall production and return. The experiment consisted of four treatments, viz. i) sweet potato 100%+lentil 20%, ii) sweet potato 100%+linseed 15%, iii) sweet potato 100%+ coriander 15% and iv) sweet potato sole 100% (60cm×30cm) were used in the study. Results indicated that diverse intercropping systems had an impact on the sweet potato’s yield and yield-contributing traits, and that overall productivity had increased as a result of the added output of pulse, oil seed, and spice crops.When comparing intercrop combinations to base crops, the gains in total productivity in terms of sweet potato equivalent yield (SPEY) ranged from 2 to 17 t/ha. In comparison to solitary crops, all intercropping combinations had greater sweet potato equivalent yields, gross returns, and benefit cost ratios (BCR). In terms of sweet potato equivalent yield (47.31 t/ha), gross return (Tk.425790/ha), and benefit cost ratio, sweet potato 100%+lentil 15% was the most practical and profitable intercropping method (3.67). The sweet potato 100%+lentil 15% intercropping system likewise produced the highest land equivalent ratio (1.17). The findings suggested that intercropping sweet potato and lentil at a rate of 15% might be most productive and profitable.
