Pineapple ( (L.) Merrill) is among the main fruits produced in West Africa. This is also the case for the Republic of Benin, where pineapple fruit is regarded as an important crop for numerous producers in the Southern part of the country. However, crop production is constrained by various issues, the major one being poor yield caused by current agronomic practices. This has become a bottleneck that affects high-quality fruit production. The objective of this research was to (i) conduct a comprehensive analysis of the current fresh pineapple production system with a focus on trends over a decade and (ii) explore the compounds used to artificially induce flowering of pineapple plants, along with the perception of fresh pineapple producers on the use of calcium carbide (CaC) on their health. Semi-structured interviews were conducted with 308 producers. Our results indicate that agronomic practices were diverse, with the involvement of more women in pineapple production over the last decade. A decrease in the involvement of young people was also observed. Cv. Sugarloaf remains the main cultivar grown, with a slight increase in cv. Smooth Cayenne. Increasing numbers of pineapple producers applied chemical fertilizers, with an increase in the use of potassium sulphate (KSO). Artificial flowering induction practices such as adding (i) petroleum/motor oil, (ii) cooking salt, (iii) liquid fertilizer ("Super Gro"), or (iv) urea to calcium carbide were reported, as well as health issues related to the use of calcium carbide. The research highlights the need for further studies on the use of alternatives to calcium carbide for artificial flowering induction in pineapple production in Benin.
菠萝（(L.) Merrill）是西非主要的水果之一。贝宁共和国也是如此，在该国南部，菠萝被众多生产者视为一种重要作物。然而，作物生产受到各种问题的制约，其中主要问题是当前农艺实践导致的产量低下。这已成为影响高品质水果生产的瓶颈。本研究的目的是：（i）对当前新鲜菠萝生产系统进行全面分析，重点关注十年间的趋势；（ii）探索用于人工诱导菠萝植株开花的化合物，以及新鲜菠萝生产者对使用电石（CaC）对其健康影响的看法。对308名生产者进行了半结构化访谈。我们的结果表明，农艺实践多种多样，在过去十年中参与菠萝生产的女性增多。同时也观察到年轻人的参与度有所下降。“砂糖面包”品种仍然是主要种植品种，“光滑卡宴”品种略有增加。越来越多的菠萝生产者施用化肥，硫酸钾（KSO）的使用量有所增加。报告了一些人工催花诱导方法，如在电石中添加（i）石油/机油、（ii）食盐、（iii）液体肥料（“超级生长剂”）或（iv）尿素，以及与使用电石相关的健康问题。该研究强调有必要进一步研究在贝宁菠萝生产中使用替代电石进行人工催花诱导的方法。
