Rice yield is low at 2.1 t ha−1 in sub-Saharan Africa. Increased yield is a critical challenge to food security and environmental conservation in this region. However, smallholder farmers have limited access to irrigation, mineral fertilizers, and improved crop varieties. One approach that even resource-limited farmers can easily manipulate is to optimize planting densities. However, there is limited empirical evidence to provide technical recommendations under such low-yielding conditions.

优化马达加斯加高原低产环境下低地水稻生产的移栽密度


撒哈拉以南非洲的水稻产量很低，为 2.1 t ha−1。提高产量是该地区粮食安全和环境保护面临的重大挑战。然而，小农户获得灌溉、矿物肥料和改良作物品种的机会有限。即使是资源有限的农民也可以轻松操纵的一种方法是优化种植密度。然而，在这种低产量条件下提供技术建议的实证证据有限。
