Abstract: A field experiment was conducted to evaluate the relative costs and return in Mukhi kachu cv. Bilashi production as influenced by different levels of urea and MP fertilizers and their time of application. Four levels of urea and MP fertilizers viz., F0, F1, F2 and F3 and four times of application were used in this investigation. Different doses of urea and MP fertilizer and their time of application had significant influence on yield of Mukhi Kachu. The combination of the highest level of urea and MP fertilizer (300 kg each of urea and MP/ha) and application of 1/3 dose each at 60, 100 and 140 DAP gave the highest yield of corms (7.20 t. ha-1) and cormels (47.89 t. ha-1). The highest gross return, net return and the best economic return (BCR) were Tk. 205820 ha-1, Tk. 125905 ha1 and 2.58, respectively obtained from the same treatment.
