Abstract:
Optimization of crop productivity and sustainability should be achieved through
optimization of seed germination and viability of seedlings. This study examined
how certain sound frequencies affect the early development of Chili (Capsicum
annuum) seeds to find eco-friendly, non-chemical methods for maximizing
seedling vigour. In here, the effects of frequencies of sound such as 125 Hz, 250
Hz, and 500 Hz were used to check the germination and early growth of Capsicum
annuum seeds as pertaining to identify the best frequency which encourage the
seedling growth. The experiment was conducted under a controlled environment
where seeds were exposed to single sound frequencies for four hours daily with
constant environmental conditions along with two controls (ambient and no
sound). Important growth characteristics like germination percentage, shoot and
root length, seedling weight, and chlorophyll content were monitored on a 15-day
regimen. Results indicated that at 250 Hz sound frequency, it showed the maximum
germination percentage, shoot and root elongation, and seedling vigour, while 125
Hz caused an increase in the content of chlorophyll to the highest level. 500 Hz
treatment caused variable effects and the control sound group never lived up to
expectation. In addition to this, the development of fungi along with seedlings was
affected due to treatments with sounds. According to this research, 250 Hz sound
frequency was confirmed as the best sound frequency for promoting germination
of Capsicum annuum seeds and development of seedlings. Seeds treated with this
frequency showed more germination, shoot and root elongation, and chlorophyll
content than controls involving no sound and ambient sound. These results show
that the processing of sound frequency can be an environmentally friendly,
chemical-free method for increasing crop yield.
