Lunar rhythms in agriculture - review on scientific perspectives

An attempt is made to review the salient research findings of the application of astronomical ephemeris in agriculture. In biodynamic agriculture, lunar rhythms are used as a calendar for scheduling farming operations like tilling, planting and harvesting of crops. Studies reveal seed germination, growth and production of crops are appraised due to the lunar influences. The scientific understanding of rhythms and its reflection through 12 zodiac signs are evident in multiple germination studies, growth and yield analysis on crops. Since these are non-monitoring inputs, more insights into rhythms and their physiological response that results in high-end physiological and biochemical characterization of various parts of plant is warranted. Planting based on the lunar cycles is an important component of biodynamic agriculture. Though several subjective insights are shared by the farmers there is a need for region-specific scientific studies to evaluate those experiences objectively. Compared to studies on biodynamic preparations, manures and their effect on crop, few studies on planting by moon rhythms are reported under field condition. Planting in sync with lunar rhythms is a zero-cost input for the farmers to take advantage for enhancing crop production and simultaneously improve the quality of byproducts.
