Abstract
An experiment was conducted during 2001-02 and 2002-03 at the Cropping Systems Research Centre of Kerala Agricultural University, Karamana, to study the production potential and economics of new cropping sys- tems. The highest production potential and net income were obtained by rice (Oryza sativa L.), banana (Musa paradisiaca) followed by rice-rice-okra [Abelmoschus esculentus (L.) Moench] cropping systems. The nutrient management above the present package of practices (POP) recommendations also increased net income in all the cropping systems included in the study. However, the highest benefit : cost ratio was obtained in rice-rice- green manure crop dhaincha [Sesbania cannabina (Retz.) Pers.] cropping system.
