其他摘要：The experiment was conducted at Agronomy Research Field, Bangladesh Agricultural Research Institute (BARI), Gazipur during 2009-2010 to find out suitable sowing time of maize in potato + maize intercropping for maximum yield and economic return. Treatments of the experiment were: T 1 = Simultaneous sowing (SS) of potato and hybrid maize (HM), T 2 = SS of potato and composite maize (CM), T 3 = HM sown 10 days after potato planting (DAPP), T 4 = CM sown 10 DAPP, T 5 = HM sown 20 DAPP, T 6 = CM sown 20 DAPP, T 7 = HM sown 30 DAPP, T 8 = CM sown 30 DAPP, T 9 = HM sown 40 DAPP, T 10 = CM sown 40 DAPP, T 11 = Sole potato, T 12 = Sole HM and T 13 = Sole CM. The result revealed that sole potato and maize produced the highest yield, LAI, TDM and CGR. The HM showed better performance than CM. The highest equivalent yield a monetary return indicated that potato + HM sown 30 DAPP intercropping was the most productive and profitable. Bangladesh Agron. J. 2016 19(2): 11-20
