In this study, we analyzed the relationship between peanuts yields and meteorological conditions using the results of field performance tests and mesh agricultural meteorological data from 1980 to 2020. We found that the pod weight tended to increase when the temperature was high and the sunshine hours were long immediately after flowering. The pod weight of ‘Nakateyutaka’ was more affected by the meteorological condition near the flowering date than that of ‘Chibahandachi’. The pod weight in the standard sowing date (from mid-May to late May) plot was more affected by meteorological conditions than in the late sowing date (in mid-June) plot, and the pod weight in the late sowing date was more affected by climatic conditions at an earlier growing stage than the standard sowing date plot.
