Pineapple production is greatly hindered by waterlogging. This condition reduces the profitability of pineapple producer in areas frequently under temporary or permanently waterlogging soil condition. This situation weakens pineapple production and accentuate poverty in rural small-scale pineapple family producers, imbalance diet of consumer and high failure risk for young entrepreneur engage in transformation and commercialization of pineapple fruits. This study investigates the potential of ridge height and planting density on the growth and yield of in waterlogged soil conditions. A split-plot design was employed, featuring three levels of ridge height (15 cm, 30 cm, and 45 cm) and two planting densities (27,777 and 57,142 plants.ha) with four replications. Data was collected on shoot and root at growth, yield formation and harvest stage. The results indicated that a ridge height of 30 cm significantly enhanced root development, leaf area, and fruit yield, achieving an increase of 149% in yield with crown compared to 15 cm ridges. A ridge height of 45 cm creates a capillary barrier approximately 15 to 20 cm below the top of the ridge, which alters water movement within the soil during both wet and dry periods. Additionally, increased planting density resulted in improved resource utilization without adversely affecting growth parameters. The highest fruit yield of 86.9 t.ha was recorded at 30 cm ridge height with a density of 57,142 plants.ha, demonstrating the potential of optimized agroecological practices in enhancing pineapple production in waterlogged conditions. Incorporating soil moisture sensors, as noted in recent studies, could optimize water management and prevent water stress, contributing to more stable yield outcomes. Appropriate ridge height and optimal plant density optimize resource use by pineapple plant in waterlogging soil condition.
菠萝生产受到涝害的严重阻碍。这种情况降低了在经常处于临时或永久涝渍土壤条件地区菠萝种植者的盈利能力。这种状况削弱了菠萝生产，加剧了农村小规模菠萝家庭生产者的贫困、消费者饮食不均衡以及从事菠萝果实加工和商业化的年轻企业家的高失败风险。本研究调查了在涝渍土壤条件下垄高和种植密度对菠萝生长和产量的影响。采用裂区设计，设置三个垄高（15厘米、30厘米和45厘米）水平和两种种植密度（27,777株/公顷和57,142株/公顷），重复四次。在生长、产量形成和收获阶段收集地上部和根系的数据。结果表明，30厘米的垄高显著促进了根系发育、叶面积和果实产量，与15厘米的垄相比，带冠产量增加了149%。45厘米的垄高在垄顶以下约15至20厘米处形成了一个毛管屏障，这在湿润和干燥时期都会改变土壤中的水分运动。此外，种植密度的增加提高了资源利用率，且未对生长参数产生不利影响。在30厘米垄高、57,142株/公顷的密度下，最高果实产量达到86.9吨/公顷，表明优化的农业生态措施在涝渍条件下提高菠萝产量方面的潜力。如最近的研究所指出的，引入土壤湿度传感器可以优化水分管理并防止水分胁迫，有助于实现更稳定的产量结果。合适的垄高和最佳种植密度可优化菠萝植株在涝渍土壤条件下的资源利用。
