The intercropping is a production system that aims to provide increased yield with less environmental impact, due to greater efficiency in the use of natural resources and inputs involved in the production process. An experiment was carried out to evaluate the agronomic viability of kale and New Zealand spinach intercropping as a function of the spinach transplanting time. (0, 14, 28, 42, 56, 70, 84 and 98 days after transplanting of the kale). The total yield (TY) and yield per harvest (YH) of the kale in intercropping did not differ from those obtained in monoculture. The spinach TY was influenced by the transplanting time, the earlier the transplanting, the higher the TY. The spinach YH was not influenced by the transplanting time, but rather by the cultivation system. In intercropping, the spinach YH was 13.5% lower than in monoculture. The intercropping was agronomically feasible, since the land use efficiency index, which was not influenced by the transplanting time, had an average value of 1.71, indicating that the intercropping produced 71% more kale and spinach than the same area in monoculture. Competitiveness coefficient, aggressiveness and yield loss values showed that kale is the dominating species and spinach is the dominated.
间作是一种生产系统，旨在通过提高自然资源和生产过程中投入资源的利用效率，在减少对环境影响的情况下提高产量。开展了一项实验，以评估羽衣甘蓝和新西兰菠菜间作的农艺可行性，该可行性是菠菜移栽时间（羽衣甘蓝移栽后0、14、28、42、56、70、84和98天）的函数。间作中羽衣甘蓝的总产量（TY）和每次收获的产量（YH）与单作中的产量没有差异。菠菜的TY受移栽时间影响，移栽越早，TY越高。菠菜的YH不受移栽时间的影响，而是受种植系统的影响。在间作中，菠菜的YH比单作低13.5%。间作在农艺上是可行的，因为土地利用效率指数不受移栽时间影响，其平均值为1.71，这表明间作生产的羽衣甘蓝和菠菜比相同面积的单作多71%。竞争系数、侵略性和产量损失值表明，羽衣甘蓝是优势种，菠菜是劣势种。
