英文文献摘要：
Fertilizer use in Nigeria is estimated at 13 kg/ha, which is far below the 200 kg/ha recommended by the Food and Agricultural Organization (FAO). The objective of this investigation was to identify the determinant factors of farmers’ participation in the Nigeria’s growth enhancement support scheme (GESS). In addition, we determined the impact of the GESS on fertilizer use in rural areas. One thousand, two hundred rural farmers were sampled across the six geopolitical zones of Nigeria. Results from the use of recursive bivariate probit model indicated that GESS significantly impacted on the access and usage of fertilizer among the rural farmers; and that contact with extension agents, ownership of mobile phones, power for charging phone batteries, value output, mobile network coverage, ability to read and write were positive determinants of rural farmers participation in the GESS; whereas increased distance to registration and collection centers, and cultural constraints to married women reduced farmers’ tendency to participate in the GESS. The findings suggest that farmers’ participation in the GESS is a critical factor for raising fertilizer use in Nigeria. This implies that food security in sub-Saharan Africa can be achieved by increasing the participation of rural farmers in the growth enhancement support scheme.
尼日利亚的化肥使用量估计为13公斤/公顷，远低于粮食及农业组织(粮农组织)建议的200公斤/公顷。本调查的目的是确定农民参与尼日利亚促进增长支持计划(GESS)的决定因素。此外，我们确定了GESS对农村地区肥料使用的影响。在尼日利亚的六个地缘政治区域，对1200名农村农民进行了采样。使用递归双变量probit模型的结果表明，GESS显著影响了农户对肥料的获取和使用;与推广代理的接触、手机所有权、手机充电电量、价值输出、移动网络覆盖、读写能力是农户参与GESS的积极决定因素;然而，离登记和收集中心的距离增加，以及对已婚妇女的文化限制，减少了农民参与GESS的倾向。研究结果表明，农民参与GESS是尼日利亚提高化肥使用的一个关键因素。这意味着，可以通过增加农村农民参与促进增长支助计划来实现撒哈拉以南非洲的粮食安全。
