An investigation was conducted at farmers’ field of Baliakandi, Rajbari, during three consecutive rabi seasons of 2001 to 2003 to find out the optimum fertilizer dose of onion for greater Faridpur region under AEZ 12. Four different levels of NPKS viz. control, medium yield goal (MYG), high yield goal (HYG) and HYG X 1.3 were tested with Taherpuri variety of onion. Average of three years study reveals that a considerable response of onion to NPKS was observed. However, the response to N and P was more distinct in comparison to K and S. From the average yield data, a response curve was drawn and the relationship was quadratic in nature. The nutrient dose that maximized yield (107-72-90-33 kg NPKS/ha) as well as profit (95-50-70-32 kg NPKS/ha) of onion cultivation was found out from the response curve. Download
