A total of 247 farmers adopting the rice-corn farming systems and 80 adopting the rice-onion farming systems were the respondents of the study. The rice-corn farmers were categorized into two: rainfed rice-corn farmers and irrigated rice-corn farmers. Rice-onion farmers follow an irrigated type of farming system.
Not all the area utilized for rice was utilized for onion and corn. The rice-based crops were always smaller in farm size compared to rice.
Cultural management practices adopted by rice-corn and rice-onion farmers particularly on fertilizer application and pest/weed control widely varied. As such yields also varied. The total expense per hectare was higher for onion than rice; while rice and corn were almost the same.
Labor input for rice was higher than corn but lower than onion, hence farm expenditures was more in rice than in corn. The reverse was observed in rice-onion farming systems.
High labor cost, pest and soil problems, high seed cost and low price were among the major constraints to rice-onion and rice-corn farming systems.
