With the results shown, the behavior of agricultural yield is indicated, reported for Cuba during the last 30 years (1990 to 2019) in the statistical yearbooks of the branch, as well as its relationship with Solar Activity (AS) and geomagnetic. The central objective is to corroborate whether, for the geographical conditions of Cuba, the synchronism that in other regions of the planet shows agricultural production with respect to the multiannual cycles of Solar and Geomagnetic Activity is manifested in the corresponding time series. It was found that, through analysis of time series, cross-correlation and with the use of the Fast Fourier Transform (FFT), that in most cases a quasi-periodic variability in performance is manifested, whose main period is in the order of 10 to 12 years, typical of the helio-geophysical variables used. It is justified to give continuity to the analysis already carried out and presented here, as a comparative advance with previous results. The classic statistical analysis of the time series is presented, which shows a marked synchronism, which is corroborated by spectral analysis. The confirmation of the results obtained could be an important tool to take into account in the strategies for the production of food of agricultural origin, by allowing the forecasting of future productive behaviors and consequently a better and more profitable planning of resources in the medium and long term.
