Variety and Planting Density Effects on Grain and Fodder Yield of Groundnut, Ghana

Groundnut is the most important food and feed crop in West Africa. Grain and fodder yields on farmers field in Ghana are low due to limited use of improved varieties and inappropriate agronomic practices such as low planting densities. An on-farm was conducted over a three-year period to evaluate the effect of plant density on grain and fodder yields of improved groundnut varieties in northern Ghana.

花生（Groundnut）是西非地区最为重要的粮食与饲料作物。加纳农户田间的花生籽粒与饲料产量偏低，原因在于改良品种应用不足以及种植密度过低等不当农艺措施。本研究于加纳北部开展了为期三年的田间试验，以评估种植密度对改良花生品种籽粒与饲料产量的影响。
