As agricultural science seeks sustainable and holistic methods to enhance crop productivity, unconventional variables such as subtle energy fields have gained academic interest. This study investigates the impact of spiritual energy (an intentional, non-physical intervention) on the growth, physiological development, and yield of the bottle gourd (Lagenaria siceraria L.). The experiment was performed dividing into two groups: control group (subjected to standard agronomic practices without energetic intervention) and a treatment group (exposed to remote spiritual blessing energy session by a distinguished experienced practitioner). The spiritual blessing energy was transferred through distance mode via online web-conferencing platform. The findings indicate that the treatment group exhibited improvement of vegetative features such as plant vigor, plant growth habit, stem pubescence, leaf size., colour of leaf blade, fruit skin, and seed compared to the control. Additionally, plant vine length and leaf width were significantly increased by 55.65% (p = 0.005) and 44.67% (p ≤ 0.001) in the spiritual blessing energy treated bottle gourd group (BTBOGG) compared to the control (CONBOGG). Seed width and fruit yield per hectare were significantly increased by 45.28% (p ≤ 0.001) and 47.32%, respectively, in the BTBOGG than CONBOGG. In conclusion, the study demonstrates that the application of remote spiritual blessing energy treatment, delivered via a non-physical, intentional intervention, resulted in a statistically significant enhancement of both the vegetative, reproductive, and yield parameters of the Bottle Gourd (Lagenaria siceraria L.).
