The economical analysis complements the evaluation of the intercrop systems efficiency, considering besides the physical production of crops, the price of products according to their quality classification and time of the year. Intercropping systems of lettuce and cucumber in two plant populations under greenhouse were economically evaluated in winter-spring, in Jaboticabal City, São Paulo State, Brazil. The total operating cost (TOC) of cucumber and lettuce as sole crop and intercropping were estimated, as well as gross revenue (GR) and operating profit (OP). The labor for the crops was the component with greater participation in the TOC of crops in intercropping and single crop. Greater GR and OP were observed in intercrops established by transplanting lettuce and cucumbers on the same day. Considering the operating profit and the land efficient ratio, it is recommended the intercropping of lettuce transplanted until 10 days after the transplanting (DAT) of cucumber with two rows per plot, and at 0 DAT of cucumber grown with a row plot.
经济分析对间作系统效率评估起到补充作用，除了考虑作物的实际产量外，还会根据产品质量分级和一年中的时间来考量产品价格。在巴西圣保罗州雅博蒂卡巴尔市，对冬季-春季温室中两种种植密度下生菜和黄瓜的间作系统进行了经济评估。估算了黄瓜和生菜单作及间作的总运营成本（TOC）、毛收入（GR）和运营利润（OP）。在间作和单作中，作物的劳动力是总运营成本中占比更大的组成部分。在同一天移栽生菜和黄瓜所建立的间作中，观察到更高的毛收入和运营利润。考虑到运营利润和土地利用效率比，建议在黄瓜移栽后10天内移栽生菜进行间作，每块地种两行，黄瓜移栽当天种植的生菜种一行。
