Abstract

Faced with the challenges of extreme climatic events and increasing food demand, cowpea farming offers a viable option for generating grains and foliage while aiding soil preservation. This research aimed to evaluate the impact of diverse organic fertilizers and plastic mulches on cowpea yields and soil macrofauna. A completely randomized block design was employed, with a factorial arrangement of 3 × 3 + 1, encompassing plastic mulch (3.5 mm) color (white, black, and blue), organic fertilizer (compost of chicken manure-agricultural soil-dolomite, island guano, and cattle manure compost), as well as a control (without synthetic mulch and organic fertilization). The study evaluated soil temperature, plant height, area biomass, foliar macronutrients, yield, and soil macrofauna. The findings demonstrate that soil temperature varies based on the color of the plastic mulch. It was observed that using organic fertilizers resulted in significantly taller plants than the control group, with fresh and dry biomass weight also being significantly greater (p<0.05) for cattle manure compost compared to the other treatments. Furthermore, the use of plastic mulches had an impact on soil macrofauna. Cowpea displayed resistance to low soil fertility and fluctuations in soil temperature ranging from <35°C to >40°C. However, high precipitation during the fruiting and harvesting seasons significantly impacted grain yields. Organic fertilizers produced noticeable variances (p<0.05) in the aerial biomass weight of cowpeas, particularly cattle manure compost. The data, indicates that soil macrofauna, like the earthworm Pontoscolex corethrurus, improved the availability of N, P, and K to the plant during the reproductive stage. Plastic mulches and organic fertilizers were linked to an increase in earthworm weights, specifically P. corethrurus. Additionally, plastic mulches served as a physical barrier against ants and bugs.
Vigna unguiculata:面对气候变化的生产选择?
面对极端气候事件和日益增长的粮食需求的挑战,豇豆种植提供了一个既能生产谷物和叶片又能保护土壤的可行选择。本研究旨在评估多种有机肥和塑料覆盖物对豇豆产量和土壤大型动物的影响。研究采用完全随机区组设计,因子排列为 3 × 3 + 1,包括塑料地膜(3.5 毫米)颜色(白色、黑色和蓝色)、有机肥料(鸡粪-农业土壤-白云石堆肥、海岛鸟粪和牛粪堆肥)以及对照(无合成地膜和有机肥)。研究评估了土壤温度、植株高度、面积生物量、叶面宏量营养素、产量和土壤大型动物。研究结果表明,土壤温度因塑料地膜的颜色而异。据观察,使用有机肥后,植株高度明显高于对照组,新鲜和干燥生物量重量也明显高于对照组(p40°C)。然而,结果期和收获期的高降水量对谷物产量有很大影响。有机肥对豇豆的气生生物量重量产生了明显的差异(p<0.05),尤其是牛粪堆肥。数据表明,土壤中的大型动物,如蚯蚓(Pontoscolex corethrurus),提高了植物在生育期对氮、磷和钾的利用率。塑料覆盖物和有机肥与蚯蚓(特别是核心蚯蚓)体重的增加有关。此外,塑料覆盖物还起到了抵御蚂蚁和虫子的作用。
