Abstract
Aim: To understand and reason out the effect of lunar phases on the rice crop growth and development.
Study Design: Experiment was laid out in Factorial Randomized Block Design.
Place and Duration of Study: Field trial was conducted in the wetland farm of Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu during the Navarai season (Dec. 2021 – Apr. 2022).
Methodology: Treatment consists of two factors viz., Sowing date (4 Nos.) weekly sowing with respect to lunar phases – New moon, first quarter, full moon and third quarter) and Varieties (4 Nos.) in which two organic (i.e. Kullakar, Karunkuruvai) and two conventional varieties (ADT 43, ASD 16). Normal cultivation practices were followed as per the Tamil Nadu Crop Production Guide 2021.
Results: The pooled mean value revealed that the seeds sown at full moon gave significant positive influence on the growth parameters such as plant height, number of tillers, leaf area index and dry matter production compared to other sown dates. Whereas the treatments that had flowering stage synchronized with full moon phase were produced more yield and dry matter content.
Conclusion: The rice varieties sown in full moon phase exhibited superior growth on compared to other lunar phases and the treatments had flowering synced with full moon phase resulted with more yield and dry matter production.
