ABSTRACT
The experiment was conducted at Agronomy Division, Regional Agricultural Research Station (RARS), Bangladesh Agricultural Research Institute (BARI), Burirhat, Rangpur, Bangladesh during 2011-2012 to find out the pattern base fertilizer dose and irrigation number for Potato -Potato / Maize / Mungbean – T. Aman rice cropping pattern. The fertilizer doseses and irrigations treatments were- T1: Native Fertility (NF), T2: 50% Recommended Fertilizer Dose (RFD), T3: 75% RFD, T4: 100% RFD, T5: 125% RFD and T6: Integrated Plant Nutrient System (IPNS) RFD and Number of 1, 2 and 3 irrigations of each crop of the cropping pattern. The GM and BCR were increased like IPNS fertilizer dose for fertilizer and three time irrigations for second potato, maize, mungbean and T. Aman rice crop and two irrigations for first potato, of the cropping pattern were performed better.
Keywords: Response, Fertilizer, Irrigation and Five crop base cropping pattern.
