Effect of Weak Sinusoidal Magnetic Field on Germination and Yield of Cotton (Gossypium spp.)

This paper presents the results of a preliminary study on the effects of sinusoidal magnetic fields on percentage germination, growth, and yield of cotton (Gossypium species). The paper covers a brief account of the experimental setup, protocol, and the essential parameters employed. The study was carried out using var.spch‐1 cotton seeds having three different germination capacities (Type 1—31%, Type 2—49%, Type 3—64%). The seeds were subjected to magnetic fields with nine different frequencies and intensities as follows: A. 1 Hz, 100 nT; B. 1 Hz, 1500 nT; C. 1 Hz, 4000 nT; D. 10 Hz, 100 nT; E. 10 Hz, 1500 nT; F. 10 Hz, 4000 nT; G. 100 Hz, 100 nT; H. 100 Hz, 1500 nT; I. 100 Hz, 4000 nT. In Type 3 cotton seeds exposed to 10 Hz, 100 nT fields, the yield was 75.3% higher than that of control, and in Type 2 cotton seeds exposed to 100 Hz, 1500 nT fields, the yield was 85.2% higher than that of control.The experiment leads to two major clear‐cut findings: Pre‐sowing exposure of seeds to extremely low frequenc...
