摘要

无机肥料是为水稻作物提供必要营养并提高其生产力的替代方法。为了确定决定无机肥料技术采用和雨养水稻产量的因素,对贝宁4个农业发展中心(ADC) 11个城市的763名农民进行了调查。从227个农民的农田中收集了复合土壤样本,并在实验室进行了分析。在这些不同的田地里测定了雨养水稻的产量。采用R 3.5.1软件对收集的数据进行分析。结果表明,采用无机肥料技术与年龄、受教育程度、家庭规模、水稻对家庭收入的贡献和有机肥使用量有显著关系(0.004 kg•ha - 1,平均值为74.68 kg•ha - 1)。不同农民施用无机肥料的数量差异更大,范围从4.58%到90.5%,平均为研究建议水平的27.15%。然而,氮、磷、钾、有机碳、pH水和阳离子交换能力决定了雨养水稻的产量。旨在向雨养稻农推广无机肥料的政策必须考虑到这些因素。

Inorganic Fertilizer Adoption, Use Intensity and Rainfed Rice Yield in Benin
Inorganic fertilizers are alternative ways of providing the necessary nutrients to rice crop and increase its productivity. In order to identify the factors determining inorganic fertilizer technology adoption and rainfed rice yield, a survey was carried out among 763 farmers in 11 municipalities in four agriculture development centers (ADC) of Benin. Composite soil samples were collected from 227 farmer fields and analyzed at the laboratory. Rainfed rice yields were determined in these different fields. Data collected was analyzed with R version 3.5.1 software. Results show that inorganic fertilizer technology adoption depends significantly on age, educational status, household size, contribution of rice to household income and organic fertilizer use (0.004 kg•ha−1 with a mean of 74.68 kg•ha−1. The quantities of inorganic fertilizer applied differ more importantly from one farmer to another and range from 4.58% to 90.5% with a mean of 27.15% of the level recommended by research. However, nitrogen, phosphorous, potassium, organic carbon, pH water, and exchanging capacity cation determine the rainfed rice yield. The policies that aim at promoting inorganic fertilizer among rainfed rice farmers must take into account these factors.
