大米是尼日利亚的主要粮食作物，但该作物的供应受到几个因素的限制，如收获后损失(PHL)。PHL对家庭粮食和营养安全构成威胁，因为它导致家庭粮食生产的质量和数量下降。这项研究是为了增加我们对这一威胁的了解，以期提供持久的解决方案。利用从尼日尔州100个稻农的农村调查中收集的初步数据，我们确定了水稻中苯丙氨酸的阶段、原因、数量和价值。我们发现，在采收和采后处理、加工点、储藏期和运往储藏地或销售地的过程中，PHL的主要阶段。水稻的PHL较高，主要发生在收割期间，而精米的损失主要发生在储藏期间。不同阶段的原因是由于运输过程中使用的包装材料不佳而导致的溢出、过度干燥造成的破碎、啮齿动物的攻击、盗窃和溢出。根据这项研究的结果，我们得出结论，采后损失，特别是水稻，已被证明是对水稻生产和家庭粮食安全的威胁。我们建议国家农业推广服务机构对农民进行适当的稻米采后处理方法的教育。政府和非政府组织以补贴价格提供现代加工和储存设施，如大米去粉碎机、金属筒仓和普渡改善作物储存，可帮助降低大米的PHL。
Rice is a major food crop in Nigeria but the supply of the crop is constrained by several factors such as Post harvest loss (PHL). PHL constitutes a threat to household food and nutrition security as it leads to reduction in both quality and quantity of household food production. This study was conducted to increase our understanding of the menace with a view to proffering lasting solutions. Using primary data collected from a village survey of 100 Rice farmers in Niger State, we determined the stages, causes, quantity and value of PHL in rice. We found that the major stages of PHL were at harvesting and postharvest handling, point of processing, at storage, and during transportation to place of storage or marketing. PHL was higher with paddy rice and occurred mostly during harvesting while the losses for milled rice occurred mostly during storage. The causes at various stages were due to spillage, breakage due to over drying, rodent attack, theft, and spillage due to poor packaging materials used during transportation. Based on findings from the study, we conclude that Postharvest loss especially in paddy rice, has proved to be a threat to rice production and household food security. We recommend that the state agricultural extension service should enlighten farmers on proper postharvest handling methods for rice. The provision of modern processing and storage facilities such as rice destoners, metal silos and Purdue Improved Crop Storage by government and NGOs at subsidised rates can help to reduce PHL in rice.
