Field experiments were conducted at Tamil Nadu Agricultural University, Coimbatore, during three seasons viz., Rabi 2000, Late Rabi 2001 and Kharif 2001 seasons. The treatments comprised of four times of sowing each at fortnight interval in main plots and four fertilizer management practices in subplots, adopting a split plot design. The test maize hybrid used for the study was COH 3. The observations on economics of maize production were recorded and computed after completion of each experiment. The results of the study revealed that Kharif 2001 season sowings recorded higher economic returns followed by Rabi 2000 and Late Rabi 2001 seasons.
