Abstract

ABSTRACT Compared to monoculture, vegetable intercropping allows the optimization of environmental resources and inputs, with positive effects on the yield and profitability of the crop. This study aimed to evaluate the yield of lettuce and arugula in intercropping and intercrop evaluation indexes according to cattle manure doses. The experiment was conducted in Aquidauana, MS, Brazil. Five doses of cattle manure (0, 15, 30, 45, and 60 t ha-1) were evaluated with four replications in a randomized block design. Higher growth and yield of the intercropped species were observed when the intercrop received 60 t ha-1 of cattle manure. However, the maximum values of the variables were not reached, so better performances can be obtained with higher doses. The indexes of actual yield loss and advantage of intercropping presented higher values starting at doses of 26 and 30 t ha-1 of manure, respectively. The highest land use efficiency (1.28) was obtained with 60 t ha-1 of cattle manure, indicating the agronomic viability of the lettuce and arugula intercrop when fertilized only with cattle manure.

生菜和芝麻菜的间作和有机肥生产

与单作相比，蔬菜间作可以优化环境资源和投入，对作物的产量和盈利能力有积极影响。本研究旨在以牛粪用量为指标，评价间作莴苣和芝麻菜的产量及间作评价指标。该实验在巴西MS的Aquidauana进行。采用随机区组设计，采用4个重复评估牛粪5个剂量(0、15、30、45和60 t hm -1)。间作品种在施用60 t hm -1牛粪时生长和产量较高。但是，这些变量没有达到最大值，因此，高剂量可以获得更好的性能。实际产量损失指标和间作优势指标分别在施用26和30 t hm -1有机肥时呈现较高的数值。60 t hm -1牛粪处理的土地利用效率最高(1.28)，说明单牛粪处理的莴苣和芝麻菜间作具有良好的农艺生存能力。
