Abstract

Economic indices were computed from the experimental data obtained from the investigations carried out at Tamil Nadu Agricultural University, Coimbatore during summer and Kharif seasons of 1984 and 1985 in order to find out the influence of agromet factors and irrigation scheduling on the performance of COH 1 maize. The crop supplied with adequate moisture throughout the crop period recorded higher gross and net returns, benefit cost ratio and per day gross return which declined progressively with the level of moisture stress experienced during various growth stages irrespective of the season. Higher values of these indices were registered when the maize crop was sown on December 1 during summer and August during Kharif seasons.
