Economic efficiency of legume-cereal intercrops in conditions of organic farming

Abstract

The paper presents economic analysis of growing of legume-cereal intercropping in conditions of organic farming. Results of the analysis are based on data monitoring in chosen organic farms that grow LCI. In the paper there is also compared economic efficiency of LCI grown in organic and conventional farming system. Methodological solution results from costingness and earnings monitoring of LCI production in five chosen organic farms in the period 2007–2008.When evaluating costs existing in individual variants of LCI growing it is necessary to say that the selection of individual machines and machine aggregations represents the most important factor of influencing direct costs, namely with regard to the size of organic farms and to the area of individual field blocks. Under conditions of organic farms, the LCI production is also significantly influenced also by agrotechnical (tillage) operations. As compared with conventional farms, the final yield of both green fodder and grain is lower by 14–38%. Total direct costs per hectare of harvested LCI acreage ranged in case of fodder production from 9.249 CZK to 11.620 CZK per hectare. In case of grain production, the corresponding costs ranged from 8.848 to 9.970 CZK per hectare. In case of LCI, the direct costs of organic farms per unit of production of both fodder and grain consist mainly of material costs, which represent 63–76% and 61–68% of total expenses associated with production of fodder and grain, respectively. These direct costs are influenced also by higher prices of inputs.
