In semiarid areas producing corn in the State of Paraiba (Brazil), despite the social and economic importance of this culture associated with some types of stress mainly in semiarid regions, as well as the soils of these regions, which in many cases have a low organic matter content, generally < 1.5%, limiting the viability of the crop. The correct management of organic fertilization via fertigation is a possibility to minimize water losses by evaporation. The objective was to evaluate the vegetative growth and productive parameters of corn (Poaceae) fertigated with bovine biofertilizer under irrigation levels. The experiment was carried out under field conditions, in the locality of the agroecology sector (UEPB, Catole do Rocha, Paraiba, Brazil). The treatments were distributed in blocks at random with four replications, in a 3 × 5 split plot scheme, represented by three irrigation depths (60, 90, and 120% of ETc—crop’s evapotranspiration) that when applied daily were considered the main plots and the subplots represented by the doses of biofertilizer (0, 20, 40, 60, and 80 mL plant⁻¹) applied biweekly via fertigation, totaling to 60 experimental plants. Plants on water stress conditions inhibit their growth and production, but when associated with biofertilizer, they result in plants with greater productive potential in semiarid conditions. The blade of 120% of the ETc provided greater growth and production of corn compared with the layers of 60 and 90% of the ETc. The 50 ml plant⁻¹ biofertilizer dose provided corn growth and production compatible with conventional cultivation.

在帕拉伊巴州（巴西）的玉米半干旱地区，尽管这种文化在社会和经济上具有重要意义，但主要与半干旱地区以及这些地区的土壤有关，这种压力与某些类型的压力相关，主要是在半干旱地区有机物含量通常<1.5％，限制了农作物的生存能力。通过施肥对有机施肥进行正确管理，可以最大程度地减少蒸发引起的水分流失。目的是评估在灌溉水平下用牛生物肥料施肥的玉米（禾本科）的营养生长和生产参数。该实验是在田间条件下，在农业生态部门（UEPB，巴西的Paraiba的Catole do Rocha）进行的。治疗以随机重复的方式分四批重复分布，^-1）每两周一次通过施肥施肥，总计60株实验植物。处于水分胁迫条件下的植物会抑制其生长和生产，但是当与生物肥料结合使用时，它们会使植物在半干旱条件下具有更大的生产潜力。与60％和90％的ETc层相比，120％的ETc的叶片提供了更大的玉米生长和产量。50毫升植物^-1生物肥料的剂量提供了与常规种植兼容的玉米生长和产量。
