摘要

在干旱和半干旱环境中,水产养殖与农业的结合对于最大限度地提高水和土地的生产力至关重要,特别是考虑到全球水资源日益匮乏以及作物和渔业生产同时用水的情况。一项温室研究旨在确定鱼类污水对豇豆(Vigna unguiculata)生长、产量参数和产量的影响。试验涉及 13 种施肥处理,包括三种灌溉水(河水控制、尼罗罗非鱼(Oreochromis niloticus)、非洲尖吻鲶(Claras gariepinus))、四种肥料(10 吨/公顷的家禽、牛和羊粪)、推荐的无机肥料(150 千克/公顷的 NPK 6-20-10)以及六种鱼类污水和 50%的单独粪肥施用量(5 吨/公顷)的混合处理。与氮磷钾处理相比,联合使用鱼腥草污水和 50%的家禽粪便可显著增加茎杆直径、每株结节数、每株豆荚数和种子产量。使用尼罗河豚的污水+50%羊粪、C. gariepinus/尼罗河豚+50%家禽粪便和 10 吨/公顷家禽粪便时,达到 50%开花的天数最短。然而,施肥处理对分枝数、豆荚和根的长度、每株豆荚数、100 粒种子重量和叶片叶绿素浓度没有显著影响。这项研究表明,鱼类污水与粪肥结合可改善植物生长和种子产量,为小农提供了一种替代无机肥料的经济有效的方法。

Enhancing the sustainability of cowpea production through the integrated use of fish effluents and animal manure

Enhancing the sustainability of cowpea production through the integrated use of fish effluents and animal manure

The integration of aquaculture and agriculture in arid and semi-arid environments is crucial for maximizing water and land productivity, especially considering the increasing global water scarcity and the simultaneous use of water for crop and fish production. A greenhouse study was conducted to determine the effects of fish effluent on the growth, yield parameters, and yield of cowpea (Vigna unguiculata). The experiment involved 13 fertilization treatments, including three types of irrigation water (river water—control, Nile tilapia (Oreochromis niloticus), African sharp-toothed catfish (Clarias gariepinus), four fertilizers (poultry, cattle, and sheep manures at 10 t ha−1), recommended rate of inorganic fertilizer (150 kg ha−1 of NPK 6-20-10), and six mixed treatments with fish effluent and 50% of the applied rate of manure alone (5 t ha−1). The combined use of C. gariepinus effluent + 50% poultry manure significantly increased stem diameter, nodules per plant, pods per plant, and seed yield compared to NPK treatments. The shortest days to reach 50% flowering were obtained with the effluent of O. niloticus + 50% sheep manure, C. gariepinus/O. niloticus + 50% poultry manure, and 10 t ha−1 poultry manure. However, fertilization treatments did not significantly influence the number of branches, pod and root length, number of pods per plant, 100-seed weight, and leaf chlorophyll concentrations. This study suggests that fish effluents, when combined with manure, can improve plant growth and seed yield, providing a cost-effective alternative to inorganic fertilizers for smallholder farmers.
