Variation and comparison of forages’ cost-benefits in China

Based on the survey data of farmers who planted forages and grain crops, we calculated cost-benefit information of major forages and grain crops from the period of 2010-2014. Further, we comparatively analysed the variation. The results indicated that the net income and return rate of alfalfa declined in 2014, whereas that of ryegrass and silage corn showed an increasing trend. A comprehensive comparison showed that the average net income and return rate of alfalfa was higher than that of ryegrass and silage corn, from 2010 to 2014. The cultivation of potato and alfalfa had an economic advantage than other forages and grain crops, whereas wheat cultivation had a relatively lower economic benefit. Moreover, ryegrass and silage corn cultivation involved more labour and land cost, whereas alfalfa cultivation involved higher water and electricity costs. Finally, this study puts forth some valuable suggestions such as making amendments to the agriculture industrial structure, including the grain, economy, feed and forage crops, which would support the development of the forage industry, and establishment of a subsidy system for forages’ production factors.
